Introduction

The Florida Building Code, Residential regulates residential housing that falls under any of the following types:

Single family dwellings (homes)DuplexesMultiple single-family dwellings (townhouses) not more than three stories in height with a separate means of egress and their accessory structures

The code regulating housing is often referred to as the “Residential Code;”however, it must be noted that once a structure goes over three stories it will be regulated by the Florida Building Code, Building and the occupancy classification is called Residential. Residential occupancies regulate structures such as apartments, condominiums, hotels, resorts and dormitory housing as well as those residential structures contained in the Florida Building Code, Residential. Anytime a large number of occupants and multiple floors are involved particularly when the occupants are unfamiliar with the building and are sleeping, the codes become more restrictive. Typically the construction type on these types of structures are more fire resistant than other residential housing type buildings. The assumption is that in an individuals dwelling unit (home) they are more familiar with escape routes even in a smoke filled room.

Please note the following web sites of interest: The Florida Building Code (FBC) and Florida Residential Code (FRC) are available online at

Chapters 1-10 BuildingChapter 11 EnergyChapters 12-23 MechanicalChapter 24 Fuel GasChapters 25-32 PlumbingChapter 33 ElectricalChapter 41 Swimming PoolsChapter 43 Referenced StandardsChapter 44 Hurricane Zone

Note: Some of the chapters listed above are not addressed in this course Although the chapters of the Florida Building Code, Residential listed above are not all inclusive

in some cases they may reference residential designers, architects and contractors to other

codes, but for the most part the Florida Building Code, Residential is self contained except for

administration and energy compliance. For these requirements you must turn to the Florida

Building Code, Building. Chapters 11 through 33 as mentioned previously may refer the

professional to other legal codes such as the Florida Building Code, Mechanical;, Florida Building

Code, Plumbing, National Electrical Code and the Florida Building Code, Fuel- Gas.

Slide 5

Chapter 1

ADMINISTRATION

Chapter One of the Florida Building Code, Building lays out the process of applying for building

permits, the timing and process of plan review and subsequent inspections during the

construction phase. Remember the Florida Building Code Residential refers you to that code for

this purpose. Check with your city building department for all city, county and state codes that

may regulate the approval process.

Slide 6

Administration Chapter 1

R101.2 ScopeThe provision of the FBC, Residential shall apply to the construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal and demolition of detached one and two family dwellings and multiple single-family dwellings (townhouses) not more than three stories in height with a separate means of egress and their accessory structures.

The Florida Building Code has a separate volume for residential construction. It is part of the

Code and is only distinguished by the word residential after the title reading as Florida Building

Code, Residential. Additionally, the Code also has volumes that regulate the

construction/installation of electrical, gas, plumbing and mechanical systems which is also titled

similarly:

National Electrical Code

Florida Building Code, Fuel-Gas

Florida Building Code, Plumbing

Florida Building Code, Mechanical

Not all residential structures will fall under the FBC, Residential. The following criteria must be

met to use this volume of the Code:

Single family home

Two family home (duplex)

Multiple single-family dwellings (townhouses)

No more than 3 stories high

Each dwelling/home must have it’s own/separate means of egress (has it’s own entrance that

exits directly to the outside exterior). If a multi-family complex has entrance doors that exit into a

corridor and/or is over three stories, the structure will be regulated by the Florida Building Code

and will have an occupancy classification of Residential which will have much stricter regulations

on the materials, construction practices and means of egress layout.

Note that the scope includes any type of remodeling work that is to be done including additions,

remodeling of existing spaces including movement of walls, and replacement of equipment such

as air conditioning units, hot water heaters, etc.

Chapter 3

Removed classification for construction typeTable 500 on area limitation no longer includedHeight is still limited to 3 stories

Residential buildings more than 3 storiesFollow provisions of Florida Building Code

A few differences should be noted from editions before 2004 of the Florida Building Code,

Building. The Florida Building Code, Residential which was a new document adopted for use

beginning in 2004. This code does not include construction type classifications nor does it include

a table that regulates area limitations. However the height of any residential dwelling unit in order

to fall under the Florida Building Code, Residential is still limited to a maximum of three stories. If

a house or multi-family dwelling is over three stories in height the structure will fall under the

jurisdiction of the Florida Building Code, Building (not the residential code) and will have to follow

more stringent regulations. Additionally, the height of any wall will be limited by the materials

used to form the walls. For wood stud walls refer to Table R602.3(5). Steel framed walls cannot

exceed 10 feet in height but you can add to that an additional 16 inches for floor joists. With

masonry walls (concrete block typical) the maximum height is 12 feet plus the floor joist for above

floor (R 301.3).

Slide 9

Provisions for High Velocity Hurricane Zone

Section R301: Design CriteriaMust be constructed to safely support all loads including

Dead loadsLive loadsFlood loadsWind loads

Must transfer all loads from point of origin to foundation

All housing in the United States must be constructed to support the building materials that it is

constructed with along with the humans who occupy the house at any given time. Residential

structures are also required to be designed and built to resist live loads such as the wind loads

and the flood loads that come with hurricanes. These regulations are a requirement for housing

that is built in areas required per Figure R 301.2(1). The required construction practice is to have

the design engineered to transfer all loads to the foundation. Every building must be structurally

designed to support the dead load (weight of building construction materials), live load (weight of

building plus furnishings and occupants) and flood and wind loads that are associated with high

wind events such as hurricanes. Table R301.5 provides minimum distributed live loads in

pounds per square inch and Figure R301.2(4) provides a map showing basic wind speeds for

each county in the State of Florida.

Slide 10

Design Criteria (non- conventional construction)

Section R301.1.3

If the design of a dwelling requires construction practices not conforming to the code

Must demonstrate how it is compatible with applicable provisionsReferred to as “Engineered Design”

Sometimes in the design of a residential building the architect, contractor or designer will discover

that the design they have created for their client can not be constructed in accordance with the

prescriptive requirements of the code or they exceed the limits of R301. Section R301.1.3 allows

for engineered design for these structural elements provided the design professional can

demonstrate that the extent of such design is compatible with the performance of a conventionally

framed system. Engineered design in accordance with the Florida Building Code, Building is

permitted for all buildings and structures, and parts thereof, included in the scope of this code.

Slide 11

Design Criteria: Wind LoadsSection R301.2.1

Wind speeds determined by Figure R301.2(4)

Provides wind loads for WindowsSkylightsExterior doors

Windows and glazed openingsMust be protected from windborne debrisMeet following standards

ASTM E 1996 (LMT)ASTM E 1886 SSTD 12TAS 201, 202 and 203, or AAMA 506

The wind speeds to be met are detailed for each county in the state of Florida as outlined in

Figure R301.2 (4). Basic wind speeds are determined from Figure R301.2(4). Where loads for

windows, skylights and exterior doors (other than garage doors) are not otherwise specified, the

loads listed in Table R301.2(2) adjusted for height and exposure per Table R301.2(3), are used to

determine the design load performance requirements. If the site where the windows and doors

will be in a windborne debris regions then all must have glazed openings protected from wind-

borne debris. Glazed opening protection for wind-borne debris must meet the requirements of the

Large Missile Test of ASTM E 1996 and of ASTM E 1886, SSTD 12, ANSI/DASMA 115 (for

garage doors) or TAS 201, 202 and 203, or AAMA 506. The building products must be tested

according to these standards and pass the test. They must be able to resist breaking from not

only the force of the wind itself but also from flying debris. The ASTM standard 1996 tests window

glass and exterior door material for it’s performance of withstanding windborne debris in

hurricanes. ASTM standard 1886 is similar; however it further tests exterior materials including

hurricane shutters when the flying materials such as a wood beam becomes like a high powered

projected missile and the exterior window, door or shutters are under different air pressure

caused by hurricane force winds.

Location on Lot Section R302

Exterior walls separated by less than 6 feetMust be 1 hour rated (Table R302.1)Referred to as fire separation distance (fsd)Projections off structure must not come any closer than 4 feet from the fsd

ExceptionDetached garage within 2 feet of fsd or lot line with a roof overhang (eave) can hang 4 inches over

No openings (windows, doors) allowed in these exterior walls within 6 feet of a structure

When a dwelling unit is planned for construction on a lot the structures on adjoining lots can

influence the new buildings location. A fire separation distance (fsd) must be maintained. If

housing units are separated by less than six feet the exterior walls that run parallel to each other

must be one hour fire rated construction. Any kind of projection of these walls no matter how

small must not be any closer than 4 feet from the structure next to it. This would include roof

overhang, a bay window, a room projection or an attached garage. However, detached garages

and the overhang of a roof can encroach upon that two feet limit slightly. When exterior walls of

separate structures on adjoining lots are separated by less than six feet, no doors or windows are

allowed in either one of the exterior walls. Fire can spread very quickly from one structure to the

next by leaping from one house to the house next door through doors and windows. When fire

consumes one structure it seeks more oxygen and goes to flash over blowing out windows and

doors in search of that oxygen catching the neighboring house on fire almost immediately.

Slide 14

This illustration shows fire separation distance (fsd) as it must be maintained.

Slide 15

Minimum Room Sizes Section R304

At least 1 habitable room120 square feet

Other rooms min. 70 square feetException

Kitchens Any room

Horizontal dimension no less than 7 feetSloping ceiling in an area less than 5 feet horizontally, furred ceiling less than 7 feet

not be considered habitable area

Room size and ceiling heights are requirements that were put in place for the health and well

being of the occupants. It can also limit the number of individuals that could be in a dwelling unit.

Whole families would live in very crowded conditions leading to the spread of disease and with

poor sanitary conditions. These codes were put in place to limit the number of occupants of each

dwelling unit and/or regulate the size and height of each room. This requires the building owner

to maintain safe conditions for inhabitants. In the above requirements, the ceiling heights are

addressed to ensure that the minimum square footages are provided. The code does not prohibit

these spaces, but it does not allow them to be counted as part of the required square footage. To

limit overcrowded conditions, minimum room sizes must be maintained including all habitable

rooms which must be maintained at not less than 70 square feet and at least one habitable room

must be a minimum of 120 square feet. The only exception is kitchens. It should be noted that

no room (except kitchens) can be less than 7 feet in any direction. For example, a room can be

at a minimum 7 feet X 10 feet for a total square footage of 70. However, a room that is 6 feet X

12 feet is not acceptable even though it is 72 square feet.

Slide 16

This illustration shows how ceiling height will determine whether an area is large enough to be

habitable.

Slide 17

Toilet, Bath & Shower Section R303 & 307

Section 303: Light, Ventilation and HeatingBathrooms must have minimum of 3 sq. feet of window

One half must be openable

Bathroom fixtures Required to follow Fig. R307.1

Walls in tub and shower areasMust be finished with nonabsorbent material

Must be maintained up to 6 feet A.F.F.

The Florida Building Code, Residential requires that all bathrooms have a window that is a

minimum of 3 square feet and one half must be openable. This allows natural daylight and

ventilation which has been established for the health and welfare of the occupants. Again to

assure that spaces are not too small for habitation, fixtures such as lavatories (sinks), water

closets (toilets) and tubs/showers meet minimum spacing requirements that are shown in Fig.

R307.1.

The floor and walls that are to be behind a tub/shower fiberglass surround or tile must be a

nonabsorbent material and that the nonabsorbent material must go up at least 6 feet A.F.F. even

if it is a tub only unit (R307.2).

Slide 18

FIGURE R 307.1 MINIMUM FIXTURE CLEARANCES

Slide 19

Glazing Section R308

Glazing used in the following ways are considered hazardous (must use safety glazing) R308.4

Glazing used in swinging doorsSliding doorsBi-fold closet doorsStorm doorsAll glass frameless doorsAll doors for showers, tubs, steam roomsGlazing next to doors with some limitationsGlazing in an individual fixed or operable panel

Individual pane within window assembly that exceeds 9 sq. ft.Glazing that starts at 18 inches A.F.F.Top of glazing is greater than 36 inches A.F.F.Glazing that is 36 inches horizontally within a walking surface

All glazing in railings considered hazardous

When glass is used in the above conditions safety glazing is required. It is considered safety

glass when the glass shatters into thousands of very small pieces when broken which keeps the

occupant from coming into contact with shards of glass that is hazardous. It is used in areas

where people might fall against glass. Except as indicated in Section R308.1.1, each pane of

glazing installed in hazardous locations must be provided with a manufacturer’s or installer’s

label, designating the type and thickness of glass and the safety glazing standard with which it

complies, which is visible in the final installation. The safety glazing label must be acid etched,

sandblasted, ceramic-fired, embossed mark, or shall be of a type which once applied cannot be

removed without being destroyed.

Slide 20

Garages and Carports Section R309

Fire separation wall between house and garage (R309.2)

½ inch gyp. board on garage sideIf habitable rooms above garage

5/8 inch type “X” gyp. Board

Garage floor (R309.3)Non-combustible materialSloped towards drain

Attached garages need to be constructed with ½ inch gypsum on the garage side. If masonry

construction is used for the garage wall obviously gyp. board does not need to be used since

concrete block is inherently fire resistant. Additionally, it is common practice to use ½ inch gyp

board for most residential interior walls. If there is room above the garage that is meant to be

habitable the garage ceiling needs to be finished with 5/8 inch type “X” gyp board which will

provide a one hour rating.

Additionally, the garage floor needs to be of non-combustible material (usually reinforced

concrete) and the floor must be sloped either towards a drain or towards the car garage door so

any fluids leaking from the car will be moved away from the habitable part of the house. All of the

listed requirements are meant to reduce the spread and/or intensity of a fire and therefore protect

the occupants.

Slide 21

Emergency Escape Section R310

Basements with habitable space and every sleeping room must have an openable emergency escape and rescue openingMust meet minimum requirements

20 inches wide X 24 inches highSill no more than 44 inches A.F.F.Net clear opening of 5.7 Sq. Ft., grade 5 Sq. Ft.

Escape opening can open into a screened enclosure, open to the atmosphere

As long as it has a door that leads away from residenceSee R310.4 for allowances of bars, grills and covers on escape openings

Emergency escape and rescue requirements were put in place to aid in the ability for occupants

to escape the structure if there is a fire or so fire fighters can enter. Openings for emergency

escape must be a minimum of 20 inches wide and 24 inches high with a net clear opening of 5.7

Sq. Ft.; at grade they can be 5 Sq. Ft.. It is recommended that openings (windows) are larger to

accommodate more individuals. Additionally these escape windows must have the ability to be

opened and not be obstructed by bars, grills and other coverings. Doors may open into a

screened in area provided that the screened area has an exterior door that would be able to lead

the occupant away from the building.

Slide 22

Means of Egress Section R311

Section regulates areas of means of egress includingStairways

Minimum head room not less than 6 feet 8 inchesMax. riser height 7 ¾ inch R311.5.3.1

Greatest riser height should not exceed the smallest by more than 3/8 inchMin. tread depth 9 inches R311.5.3.2

Greatest tread depth should not exceed the smallest by more than 3/8 inchEvery tread less than 10 inches must have a nosingNosing on stair can range from

radius no more than 9/16 inch Projection not more than 1inchBevel not more than ½ inch

Area under stairsMust be protected with ½ inch gyp. Board

Provides 1/2 hour fire rating

Section R311 details the construction requirements of the means of egress elements in a

residential structure. This includes stairways, ramps, exterior exit balconies, hallways and doors.

Stairways shall be provided with a minimum head room height (ceiling height) of 6 feet 8 inches.

Hallways shall be a minimum 36 inches wide. The dimensions for stairs are established so that

the occupant has not only adequate tread to step on but so a rhythm of movement can be

maintained as they go down the stairs with a consistent rise.

Slide 23

This illustration shows minimum tread depth and nosing requirements.

Slide 24


RampsExit BalconiesHallways; minimum width of 3 feet

Section R311 not only regulates balconies, hallways and doors, but also includes ramp ratio

requirements and the protection of areas under stairs that are used for storage by providing a ½

hour enclosure.

Slide 25

Means of Egress Section R311.4

DoorsEvery home must have minimum one exit door to exterior that meet these requirements

Side hingedNo less than 3 feet wideNo less than 6 feet 8 inches in height

All other exterior and interior doors do not have to meet these standardsMust have minimum 36 inch width landing on each side of door

No landing is required at exterior doors when there is less than two risers

Every dwelling unit must have at least one exterior door that is side hinged and a minimum of 3

feet wide by 6 feet 8 inches in height. This door is considered the primary exit. Other exterior

doors can by hinged or sliding or another type of door. Additionally, the floor on both the interior

side and exterior side of any door must have a level landing that is at least 36 inches wide

Slide 26


Ramps (R311.6)Maximum slope (R311.6.1)

Height 34 - 38 inches (R311.6.3.1)Grip size same as size of stair rail (R311.6.3.2) Continuous for length of ramp (R311.6.3.3)

Guard rails required for (R312.1)Porches, balconies, raised floor 30” above floor Guard rails

Must not be less than 36 inches in height

The maximum slope for a ramp in a residential setting is a 1:12 ratio; meaning for every 1 inch

the ramp rises there must be 12 inches of straight run. This is a preferred ratio for all ramps for its

ease in maneuvering with a wheelchair or with a walker. Where it is technically infeasible to

comply because of site constraints, ramps may have a maximum slope of one unit vertical in

eight horizontal (12.5 percent slope). With a 1:12 ratio the ramp is steep enough that the FRC

requires handrails on one side of the ramp. The handrail height for ramps is 34 - 38 inches high.

Guards are required for porches, balconies and raised floors 30 inches or more in height. Guard

rails must not be less than 36 inches.

meaning for every 1 inch the ramp rises there must be 12 inches of straight run. This is a

preferred ratio for all ramps for its ease in maneuvering with a wheelchair or with a walker. Where

it is technically infeasible to comply because of site constraints, ramps may have a maximum

slope of one unit vertical in eight horizontal (12.5 percent slope).

1 hr. fire rated wall and/or floorTested in accordance with ASTM E119

Wall must extend to roof sheathingSeparation of townhouses R317.2

Meet requirements for exterior walls R302 or a common two-hour wall

All two-family units must have a one hour fire rated wall separating each dwelling unit. In order

for the wall to maintain a one hour rating the wall must extend from the floor all the way up to the

roof. If the fire rated wall is not constructed to go all the way up to the roof, a fire can spread from

one dwelling unit to the other through the attic. Townhouses must have exterior walls of one hour

(that is two one hour walls) or they can share a common two hour wall.

Slide 29

Accessibility ForResidential Buildings

All new residential dwellings (R322)Provide one bathroom on ground floor

with not less than 29” wide door

As the population continues to age, there becomes a need for accessible housing to

accommodate the aged population as they begin to loose some physical abilities and may

possibly need to use a wheel chair. The Florida Building Code, Residential is attempting to

address the current and future needs of an aging population.

Any newly constructed residential housing of any type must have a bathroom on the ground floor

with a door no less than 29 inches wide. It should be noted that this allows a wheelchair to be

pushed through the door but does not allow comfortable maneuvering space for someone to

wheel through the door on their own. In order to provide a door wide enough for an individual to

push themselves through the door on their own without hitting elbows and scraping fingers a clear

width opening of 32 inches is recommended for doors and door openings. As the base age of the

majority of the population shifts towards an older population, meeting not only the codes but the

recommended standards will become increasingly important.

Values provided in Table R401.4.1

Chapter 4 of the Florida Residential Code regulates the design and construction of the foundation

including support loads and water drainage away from structure. Table R401.4.1 provides

acceptable values of soil for load bearing purposes. Note that wood foundations will have special

provisions that will need to be met to be in compliance with the code.

Construction design drawings required for foundation walls under the following conditions (R404.1.3)

Walls subject to hydrostatic pressure from groundwaterSupports more than 48 inches of unbalanced backfill that do not have permanent lateral support top and bottom

Concrete foundations must meet the specifications outlined in Table R402.2 for compressive

strength in order to insure that the foundation can support the structural and live load of a house.

The width of the footing is regulated by Table 403.1 Footings for the foundation must meet

further regulations which requires them to be a minimum of 12 inches below the ground. This

section of the code is taking into account that unsettled top soil can compromise the stability of

the footing and therefore the stability of the foundation as well as the need for the footing to resist

overturning. It should be noted if the foundation is subjected to underground hydrostatic pressure

or if there is foundation wall that is 4 feet down with unsettled backfill dirt without lateral support,

then additional requirements may need to be met for compliance with the code.

A large proportion of foundations and sub-flooring in Florida will be a concrete slab. The absolute

minimum thickness of a concrete slab is 3 ½ inches thick but also must be a thickness that has

the comprehensive strength to support and distribute the weight of the building, furnishings and

wind loads plus the occupants. Section R402.2 and R501 of the Florida Building Code,

Residential will regulate the comprehensive strength needed for support and distribution of all

loads. Keep in mind that all wood floors on second floors or with a stilt frame must also be able to

support and distribute loads which is further detailed on the next page. This would also include

attic areas that may not be habitable by human occupants but house mechanical or plumbing

equipment. If the dwelling unit is in the High Velocity Wind Zone greater restrictions are laid out

in Chapter 44.

See figure R502.2.8

As mentioned previously wood floors are required to support and distribute weight which is

referred to as safe spans. Wood floor joists come in a variety of lengths and the safe length

before a horizontal support beam is utilized and vertical support (wall, column) for the girder is

required will be based on the information laid out in Table R502.2.5 (1)&(2). Section R502.2.8

limits the amount of notching or drilling in any part of the wood floor. This is limited so as to

maintain the supporting integrity of the wood floor frame and sub-floor.

Section 601 of the Florida Building Code, Residential gives a general overview of how walls and

interior partitions are to be constructed in housing. Additional sections regulate more specifically

wood or steel construction methods. A few key elements to be noted are the requirement of a

double top plate that overlaps at corners and are at least a nominal 2 inches in depth and a width

at least equal to the width of the studs (R602.2.3). Cutting or notching into an exterior or bearing

wood stud is allowed if the cut or notch does not exceed 25% of the stud width. Nonbearing

studs may be notched not to exceed 40% of the single stud width. Boring and drilling may be

done to any stud as long as the resulting hole does not exceed 40% of the stud width and the

hole is no closer than 5/8 inch away from the edge of the stud. These requirements are put in

place to ensure the walls ability to support the required load and maintain it’s structural integrity

even when drilling is necessary for other parts of the construction process (see Section

R602.2.7).

In wood stud framing, fire blocking is also a requirement which is covered in section R602.1.2. All

concealed draft openings both horizontal and vertical most be fireblocked. Most frequently

fireblocking occurs vertically in the space between studs that run from the subfloor to a second

floor and/or to a roof. Fire blocking is a wood piece that is run horizontally between studs close to

the second floor and or the roof. It’s purpose is to slow the fire from spreading up through the

wall cavity from floor to floor to roof. Additionally, fireblocking is used between floor joists (a

minimum of every 10 feet) to keep the fire from spreading horizontally along the floor.

Fireblocking is also required for shared party walls in two-family dwelling structures.

Chapter 7 Wall Covering

R701 GeneralControls design/construction of all interior and exterior wallsHigh-Velocity Hurricane Zone shall comply with the provisions of Chapter 44.

Exterior coverings; Masonry veneerCan not support any vertical loadsVeneer above openings must be supported on lintels

Meet allowable spans set forth in Table R703.7.3Lintels shall not be less than 4 inches

Exterior walls on all residential structures must be weather resistant which the code refers to as a

“weather-resistant exterior wall envelope.” The weather-resistant envelope has to be constructed

in a manner that prevents the accumulation of water in the wall cavity which would include the

use of flashing as described in Section R703.8. When the exterior wall has some type of stone or

brick (masonry) veneer that is applied to the outside face of the exterior wall the veneer is only to

be used for aesthetics purposes and can not be used as any form of support. Meaning that roof

trusses’ must not extend to the brick veneer but full support must rest solely on the supporting

wall. Additionally when there is a door or window (opening) in that exterior wall with a veneer the

door or window assembly must be supported by a lintel and not rest on the veneer.

Chapter 8 of the Florida Building Code, Residential regulates the materials and construction

practices used to assemble roofs and interior ceilings. Additional regulations may be required for

housing in high wind speed zones. Check with local building department code divisions within the

community. Section 803 regulates the type of roof sheathing that can be used and wood/shaker

style shingles that can be used per Sections R905.7 and R905.8. Ceiling materials will be

regulated like interior wall finishes and typically will be ½ inch gypsum board. When installing

lighting fixtures that generate heat in the ceiling such as recessed down lights, insulation cannot

come within 3 inches of the recessed part of the lighting fixture unless listed for less. Remember

that load-bearing wood roof framing needs to be marked by a grade mark from a lumber grading

or inspection agency that has been approved by an accreditation body that complies with DOC

PS 20.

Additional regulations are required for the manner in which roof-ceilings are to be fastened to the

overall structure. Roof framing details are given in R802.3 that require specific details for ceiling

rafters where wind speeds exceed 100 MPH. Safe spans for ceiling joists should be in

accordance with Tables R802.2(1) and R802.2(2).

Chapter 9 of the Florida Residential Code covers the design, materials and construction for the

entire roof assembly. It should be noted that if the home is in the High Velocity Hurricane Zone

(HVHZ), regulations for the roof assembly will be covered in Chapter 44 of the Florida Building

Code, Residential.

Section R902 and 903 covers materials and weather protection of roofs. Roof assemblies are

classified as A, B or C for fire resistance. The closer the roof is to property line the more

restrictive the codes for fire-resistant materials. Additionally, section 903 covers weather resistant

construction, in particular, water resistant materials and construction of roof assemblies. A

weather resistant roof protects the structure from long term damage such as mold and

deterioration. The use of flashing in roof valleys and proper drainage will minimize the chance of

water entering any part of the structure from the roof.

Chapter 10 Chimneys & FireplacesR1003

Chimneys can not support any load other than own weight R1003.8

Chimneys must extend 2 feet higher than any part of building within 10 feet R1003.9

Minimum of 3 feet above highest point of where it passes through roof

Fireplace hearth R1004.2Must be distinguishable from surrounding area

Masonry chimneys must be designed and constructed to support their own weight. If any part of

the chimney is intended to support any part of a roof or wall assembly it must be designed for the

additional weight. If the walls that come in direct contact with a fireplace and chimney are of brick

(masonry) or concrete, the fireplace and chimney walls can be part of the wall assembly. The

chimney and fireplace must be separated from combustible construction by 2 inches.

Chimneys also have height limits. First they must be constructed so that they are at least two

feet above roof lines within 10 feet and 3 feet above the highest point where it passes through the

roof.

Section R1004.2 requires the hearth to be non-combustible finish and be distinguished some how

from the surrounding finish flooring. So even if the finished floor is of tile (a non-combustible

material) the hearth would at a minimum need to be either a different non-combustible material or

a different color.

Skimmers R4101.21.2Requires one skimmer per 800 sq. ft. of surface area Inlet fittings R4101.21.51 per 300 sq. ft. of surface area

Private swimming pools at residential homes are regulated by Chapter 41 of the Florida Building

Code, Residential. One skimmer is required for every 800 square feet of surface area and

designed for a flow rate of at least 25 gallons per minute per skimmer. It should be noted that the

design professional will be referenced to ANSI standards that are not spelled out in the

Residential Code but must be looked up and read as a separate document. Typically, a pool

contractor is hired who specializes in pool design and installation will have knowledge of

applicable codes.

Chapters 25, 26 and 27 regulate the installation of plumbing and subsequent inspection of the

plumbing installation by the building department. Section P2503.5.1 requires the inspector to test

all drainage systems before a home is inhabited by the owner. An additional requirement in

section P2603.3 requires pipes within walls to be protected from corrosion and breakage which

requires the building contractor to use appropriate materials and construction techniques

including overseeing that the plumbing meets code.

The centerline of water closets or bidets shall not be less than 15 inches (381 mm) from adjacent

walls or partitions or not less than 15 inches from centerline of a bidet to the outermost rim of an

adjacent water closet. There shall be at least 21 inches clearance in front of the water closet,

bidet or lavatory to any wall, fixture or door.

If water heater is fed from cold water hot water line needs to be on size larger than cold water line

Table FPC Table 604.5 determines water line type

When the code refers to plumbing fixtures it is referring to bathroom fixtures including showers,

tubs, toilets, and bidets along with sinks and faucets. Water-resistant materials need to be used in

shower areas to keep water from seeping into walls and under flooring. There is an exception to

this requirement. If the shower is on the first floor and has a drain that was poured as part of the

slab floor and it is 2 inches below the finished floor then moisture resistant wall materials do not

have to be used. The idea is that water will naturally drain more quickly to the recessed part of

the shower. Though from a quality stand point the above moisture resistant construction

materials and practices are recommended to protect the walls and other areas from water

damage and mold growth.

Chapter 29 of the Florida Building Code, Plumbing will regulate the size of water supply pipes and

fitting for bathrooms, kitchens, steam rooms and hot tubs. Both hot tubs and one-piece water

closets (toilets; such as some low-profile toilets) will require larger supply pipes than regular tubs

and toilets. The hot water pipes will need to be larger to accommodate expansion of the water

when heated and Table FPC 604.5 needs to be referred to for types and sizes of piping.

do not come back into the residence. Table P3005.1 provides the size and type of pipe fittings to

be used in homes. Table P3105.1 provides the maximum distance any drain trap can be from the

vent. Vents that are placed through exterior walls must not be any closer than 4 feet to a door or

window so that vented gases can not reenter the home. Additionally all traps must be sealed with

a liquid seal of a minimum of 2 inches but not more than 4 inches. A licensed plumber should be

aware of these requirements.

Chapter 24 Fuel Gas, G2439.5

In most single family homes it is common to vent the clothes dryer directly out through an exterior

wall. The flexible duct must be at least 4 inches in diameter and the length from the dryer vent to

the exterior can not exceed 8 feet for flexible duct.

All dryer vents must exhaust directly to outdoors and the vent can not have screens installed over

them which could cause the vent to become clogged with lint and catch on fire. The duct work

that leads from the dryer to the vent needs to be of smooth metal so lint and fibers do not get

caught in the duct.

Unlike flexible ducts which can not exceed 8 feet in length, regular metal ducts can be up to 25

feet from dryer to vent location on an exterior wall. Like clothes dryers the hood over a stove

must be vented directly to the exterior unless the range has a ductless hood which is not required

to be exhausted to the exterior.

R403.1 General. All exterior walls shall be supported on continuous solid or fully grouted

masonry or concrete footings, wood foundations, or other approved structural systems which

shall be of sufficient design to accommodate all loads according to Section R301 and to transmit

the resulting loads to the soil within the limitations as determined from the character of the soil.

Footings shall be supported on undisturbed natural soils or engineered fill. R403.1.1 Minimum size. Minimum sizes for concrete and masonry footings shall be as

set forth in Table R403.1 and Figure R403.1(1). The footing width, W, shall be based on the load-

bearing value of the soil in accordance with Table R401.4.1. Spread footings shall be at least 6

inches in thickness. Footing projections, P, shall be at least 2 inches and shall not exceed the

thickness of the footing. The size of footings supporting piers and columns shall be based on the

tributary load and allowable soil pressure in accordance with Table R401.4.1. Footings for wood

foundations shall be in accordance with the details set forth in Section R403.2, and Figures

R403.1(2) and R403.1(3).

R403.1.4 Minimum depth. All exterior footings shall be placed at least 12 inches (305

mm) below the undisturbed ground surface. Where applicable, the depth of footings shall also

conform to Sections R403.1.4.1 through R403.1.4.2.
