1004.31004.8 Posting of occupant load. No change to text.

Reason: The purpose for adding Section 1004.3, Multiple function occupanc load: The current table for determining the occupant loadfor a space or a building uses the term function. Since many of the activities noted in the table are not occupant specific that logic appearsto be correct. However, there are differing ways to determine what the occupant load is based on the measurement by net or gross area. Both terms are defined in the code, and both are exclusive of each other (they don't overlap). However, within most buildings there aremore than one function and quite often more than one occupancy. The application of Table 1004.1.2 does not provide guidance as tohow to determine which load factor to use.One very common area of confusion is often found in office buildings. The table indicates that for "business areas" that 100 sf. of grossarea would provide the basis for the occupant load. Gross floor area is by definition the entire building floor. So, a 10,000 sf. floor forbusiness would have 100 occupants. However, within a typical office there are other functions as well, such assembly. The codespecifically anticipates this in Chapter 3 and notes that assembly space within an office, with an occupant load of less than 50 is allowedto be classified as a B occupancy, thus eliminating a "mixed-use" condition. Assembly occupant loads are measured either by fixed seatsor by net area. That leaves the assembly function in the business occupancy with no direction as to what is intended by the code forcalculation of its occupant load.

The question that is constantly raised bby code users is what number should be used and what areas are they applied to? If the 100 sf.per person anticipates all the functional activities within a business function (stairs, hallways, restrooms, etc., etc.), then does it or doesn'tit include the assembly functions? If it does, then the occupant load is simple to calculate. If it doesn't, then how do you determine whatarea to ascribe to the assembly space? Do you then subtract that area from the business space?

Using the simplest example of a 10,000 sf. office floor, with a 600 sf. conference room with no chairs, the occupant load could either becalculated by the gross number (100) based on the simultaneous use concept. Or should the net area for the assembly function could bedeleted from the gross area. Assuming tables and chairs in the conference room, the occupant load for the space for that function wouldbe 40, and the remaining office occupant load would be 94. The occupant load for design of the means of egress from the floor would thenbe 134.

The reason for reorganization: The current organization for this section is random. With this reorganization of Section 1004, Section1004.2 through 1004.4 would be how spaces worked together, and Section 1004.5 through 1004.7 would be the specifics for calculating theoccupant load of each space. This will also set up this section so that where specific spaces need unique criteria (e.g. the conference roomproposal also submitted for consideration) there is a logical place to locate those sections. The final section, Section 1004.8, is for whenthat occupant load needs to be posted.

Cost Impact: Will not increase the cost of constructionThere should be little impact as this is simply clarifying how to determine the occupant load for a floor with varying functions.

a. Floor area in square feet per occupant.

Add new text as follows:

1004.6 Concentrated business use areas The occupant load factor for concentrated business use shall be appliedto telephone call centers, trading floors, electronic data processing centers and similar business use areas with ahigher density of occupants than would normally be expected in a typical business occupancy environment.Where approved by the code official, the occupant load for concentrated business use areas shall be the actualoccupant load, but not less than one occupant per 50 square foot gross of occupiable floor space.

Reason: The intent of this code change proposal is to revise the current maximum floor area allowance per occupant in Table 1004.1.2 for

business occupancies from 100 ft2/occupant (gross) to 150 ft2/occupant (gross) for determining the means of egress requirements inbusiness areas and to create a new occupant load sub-category for concentrated use areas in business occupancies having a higherdensity of occupants than would normally be expected in a typical business occupancy environment.

Our rationale is based on several past research studies that have concluded that the 100 ft2/occupant (gross) occupant load factor forbusiness occupancies is very conservative which has led to requiring Group B occupancies and office buildings in general to haveadditional egress capacity and a greater number of exits to accommodate an "over-estimated" building population. We believe the

increase from 100 ft2/occupant (gross) to 150 ft2/occupant (gross) for business occupancies is still a conservative figure; yet reasonable,based on recent changes in office building design as well as changes in the North American workplace and work style trends; such as workstation configurations, flexible work schedules, telecommuting, work at home, etc.

The existing occupant load factor of 100 ft2/occupant (gross) for business occupancies first appeared in the 3rd edition of the Building

Exits Code that was published in 1934. The occupant load factor of 100 ft2/occupant (gross) was specified for office, factory, andworkrooms. All occupant load factors were based on the gross floor area of the building, such that no deduction was permitted forcorridors, closets, restrooms, or other subdivisions. To our knowledge there is no formal record indicating the basis of the occupant loadfactors included in the 1934 Buildings Exits Code. However, it seems likely that the results from a National Bureau of Standards (NBS)[now referred to as National Institute of Standards and Technology (NIST)] study published in 1935 were the most likely basis of theoccupant load factors adopted into the 1934 Code. However, since the initial NBS study in 1935, several other studies have beenconducted to determine the occupant load factors for various occupancies. One common similarity of each of the studies was that all of

the subsequent studies have concluded that the 100 ft2/occupant (gross) occupant load factor for business occupancies is conservative.Studies conducted between 1966 and 1992 have indicated that occupant load factors in business occupancies ranged from 150

ft2/occupant (gross) to 278 ft2/occupant (gross). In addition, a 1995 study of 23 Federal sector and private sector office buildings also

indicated a mean occupant load factor of 248 ft2/occupant for all office buildings.Lastly, a recent project to study the appropriateness of

the 100 ft2/occupant load factor for business occupancies has been undertaken by the NFPA Fire Protection Research Foundation. Thestudy was conducted by WPI undergrad students. The recommendations of this study have indicated that it is reasonable to increase the

occupant load factor to 150 ft2/occupant in business occupancies and to create a new occupant load sub-category for concentrated useareas in business occupancies.

Based on the points stated above and the occupant load factor ranges cited in recent studies, I believe it would be reasonable to increase

the occupant load factor of 100 ft2/occupant (gross) in Table 1004.1.2 for determining the means of egress requirements in Business areas

to 150 ft2/occupant (gross) and to create a new occupant load sub-category for concentrated use areas in business occupancies having a

range between 50 ft2-100 ft2/occupant depending on the work environment configuration.

Cost Impact: Will not increase the cost of constructionOverall, the proposal seeks to lessen the occupant load, thus reducing the required means of egress capacity, and the number ofplumbing fixtures required for business use occupancies. However, the cost of construction may increase where occupant load factors forconcentrated business use are applied to telephone call centers, trading floors, electronic data processing centers and similar businessuse areas with a higher density of occupants by increasing the means of egress capacity as well as the number of plumbing fixtures to

2015 International Building CodeRevise as follows:

1107.7.1.2 Additional stories with Type B units. On all other stories that have a building entrancewith entrancesnot included in proximity determining compliance with Section 1107.7.1.1, that are proximate to arrival pointsintended to serve units on that story, as indicated in Items 1 and 2 below, all dwelling units and sleeping unitsintended to be occupied as a residence served by that entrance on that story shall be Type B units.

1. Where the slopes of the undisturbed site measured between the planned entrance and all vehicular orpedestrian arrival points within 50 feet (15 240 mm) of the planned entrance are 10 percent or less, and

2. Where the slopes of the planned finished grade measured between the entrance and all vehicular orpedestrian arrival points within 50 feet (15 240 mm) of the planned entrance are 10 percent or less.

Where no such arrival points are not within 50 feet (15 240 mm) of the entrance, the closest arrival point shall beused to determine access unless that arrival point serves the story required by Section 1107.7.1.1.

Reason: The contorted language in this section is difficult to follow and should be clarified. The code is trying to make it clear that morethan one entrance may provide access, and each of those entrances may serve other stories. The criteria are then used to determine if theunits that are on those other floors must have Type B units.

Cost Impact: Will not increase the cost of constructionThe intent of the code change is to clarify how the various routes into a building are to be considered and does not change the technicalrequirements, and has not impact on the cost of construction.

404.10712.1.7.9 Interior exit stairways.

Reason: Reason: Chapter 4 of the IBC includes a hodge-podge of various criteria for "special use and occupancy." However, these areoften exceptions to specific limits or allowances from having to meet such limits, or even specific requirements for specific occupancygroups. The issue in general is that they are "gotcha's" built into the code. This series of code changes moves these special criteria into thechapters and sections where these issues are typically addressed, removing any doubt in the mind of the code user as to how thesecriteria are to be integrated into the design and construction of a building that includes these features.The provisions for Atriums in Chapter 4 are a classic case of the confusion caused by the code. As defined an atrium includes virtually anyopening between two or more floors. However, in the code there are a miriad of options for openings through two or more floors andindeed, an atrium is simply only one option for creation of openings and providing the necessary protection because of that opening aslisted in section 712.1. However, because it is listed in Chapter 4 without any direction that limits its application to a choice by thedesigner, it is often cited as being necessary, when in fact it is not because another option has been chosen. Similarly, because of thedefinition other floor openings are not being permitted, which is why the definition is being deleted and the charging language in theSection 712.1 for atriums includes the appropriate limitations from the definition.

By moving the provisions for atrium design to Chapter 7 and referencing the determination of when it is to be applied, the code users will

much more readily understand the intent of the code.

Cost Impact: Will not increase the cost of constructionAs a needed clarification of the code, this will actually reduce the cost of construction where the unnecessary application of this sectionwill allow for less onerous solutions the code allows.

509.2 427.2 Occupancy classification. Incidental uses shall not be individually classified in accordance withSection 302.1. Incidental uses shall be included in the building occupancies within which they are located.

509.3 427.3 Area limitations. Incidental uses shall not occupy more than 10 percent of the building area of the storyin which they are located.

509.4 427.4 Separation and protection. The incidental uses listed in Table 509427.1 shall be separated from theremainder of the building or equipped with an automatic sprinkler system, or both, in accordance with theprovisions of that table.

509.4.1 427.4.1 Separation. Where Table 509427.1 specifies a fire-resistance-rated separation, the incidental usesshall be separated from the remainder of the building by a fire barrier constructed in accordance with Section 707or a horizontal assembly constructed in accordance with Section 711, or both. Construction supporting 1-hour firebarriers or horizontal assemblies used for incidental use separations in buildings of Type IIB, IIIB and VBconstruction is not required to be fire-resistance rated unless required by other sections of this code.

509.4.2 427.4.2 Protection. Where Table 509427.1 permits an automatic sprinkler system without a fire barrier, theincidental uses shall be separated from the remainder of the building by construction capable of resisting thepassage of smoke. The walls shall extend from the top of the foundation or floor assembly below to the undersideof the ceiling that is a component of a fire-resistance-rated floor assembly or roof assembly above or to theunderside of the floor or roof sheathing, deck or slab above. Doors shall be self- or automatic-closing upondetection of smoke in accordance with Section 716.5.9.3. Doors shall not have air transfer openings and shall notbe undercut in excess of the clearance permitted in accordance with NFPA 80. Walls surrounding the incidental useshall not have air transfer openings unless provided with smoke dampers in accordance with Section 710.8.

509.4.2.1 427.4.2.1 Protection limitation. Where an automatic sprinkler system is provided in accordance with Table 509427.1, only the space occupied by the incidental use need be equipped with such a system.

Reason: This change is intended to relocate the incidental use requirements to Chapter 4 of the IBC. Incidental uses are not occupancies.Therefore, they do not belong in the occupancy chapter. They are areas in a building that have a higher level of risk and are separatedfrom the rest of the building. By placing the requirements in Chapter 4, they are then considered special uses and will eliminate theconfusion of whether they are occupancies or not. We believe that this will provide better clarification for these areas in a building thathave special requirements. The title of Chapter 4 is Special Detailed Requirements Based on Use and Occupancy. The location of theserequirements is more appropriate in this chapter.

Reason: In July/2014 the ICC Board decided to sunset the activities of the Code Technology Committee (CTC). This is beingaccomplished by re-assigning many of the CTC Areas of Study to the applicable Code Action Committee (CAC). This proposal falls underthe CTC Area of Study entitled Relocatable Modular Buildings. Information on the CTC, including: the sunset plan; meeting agendas;minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can bedownloaded from the CTC website.This public proposal is submitted by the ICC Building Code Action Committee (BCAC). The BCAC was established by the ICC Board ofDirectors to pursue opportunities to improve and enhance an assigned International Code or portion thereof. This includes both thetechnical aspects of the codes as well as the code content in terms of scope and application of referenced standards. Since its inception inJuly, 2011, the BCAC has held 13 open meetings and numerous workgroup calls which included members of the BCAC as well as anyinterested party to discuss and debate the proposed changes and the public comments. Related documentation and reports are postedon the BCAC website at: http://www.iccsafe.org/cs/BCAC/Pages/default.aspx.

Unlike site-built buildings, which are typically intended to remain on their original site for the life of the building, relocatable modularbuildings are designed and intended for relocation, reuse and/or repurposing. Many states have statutes that govern the building andrelocating of relocatable modular buildings. For those that do not have state mandated requirements, much confusion and inconsistencyexists about the requirements for relocatable modular buildings as existing buildings. The Modular Building Institute (MBI) ( www.modular.org) estimates that there are over 600,000 code compliant relocatable buildings inuse in North America today. While it is impossible to determine the exact amount owned by the public at large, MBI estimates that publicschool districts across North America collectively own and operate about 180,000 relocatable classrooms with the industry owning andleasing an additional 120,000. Additionally, the industry owns and leases approximately 280,000 relocatable buildings for various otherbusiness occupancies, including construction site offices and temporary sales offices.Unique characteristics of relocatable modular buildings that are unlike site-built buildings include:• There are sections of the IBC that are applicable equally to both site-built and relocatable modular buildings, particularly for newconstruction.• There are sections of the conflicting code sections that cannot be applied to both site-built and relocatable modular buildings,specifically related to construction documents, inspection, and relocation.The IBC does not have specific requirements on how to treat these buildings. In the absence of clear definitions and requirements thatare specific to both new and existing relocatable modular buildings, many code officials attempt to apply similar, but non-related sectionsof the building code intended for site built buildings to the relocatable modular industry. There are unique attributes to relocatablemodular buildings that warrant their own requirements in a new chapter in this code.Two proposals have been submitted on the subject of relocatable modular buildings. One proposal for new construction (this proposal)and a second proposal to address the relocation of modular buildings (proposal to the IEBC). This proposal includes:• The definition has been reproduced from the definition that was added to the 2015 IEBC last cycle.• Identification and inclusion of relocatables into Special Construction, Chapter 31. This chapter applies to new relocatable buildings,and also new site built structures.Moving this document forward through the ICC code development process will help the modular building industry comply with theintent of the code, provide a clear and consistent path for enforcement professionals, and for compliance by owners of relocatablebuildings who wish to re-use or repurpose their existing buildings.

Cost Impact: Will not increase the cost of constructionThis code change proposal will not increase the cost of construction due to the re-usable/relocatable nature of such buildings.

2015 International Existing Building CodeAdd new text as follows:

301.1.5 Compliance with accessibility Accessible requirements for existing buildings shall comply with the 2009edition of ICC A117.1.

Reason: Dramatic changes are being proposed in the next edition of the ICC A117.1 standard that will accommodate a higher number ofindividuals. For example, the turning radius is being changed from 60" diameter to a 67" diameter, and clear floor space from 30"x48" to30"x52" and related access to features. While these changes are able to be incorporated into new construction relatively easily, existingbuildings that have been designed to conform with earlier standards or were modified to meet those earlier standards are likely to findthat full compliance will create problems. Even using provisions based on the technical infeasibility for compliance will still requirecompliance in some circumstances that aren't justifiable financially and physically.The Department of Justice in development of the 2010 ADA Standard allows for "grandfathering" of elements in an existing building thathave already been made to conform and are found to comply with the earlier ADA standard. The 2009 edition of A117.1 provides the mostcomprehensively structured provisions for compliance with the original ADA and HUD standard, which is why a specific reference to thatedition of the Standard for determining whether areas outside the specific alterations or change of occupancy must be modified.

Cost Impact: Will not increase the cost of constructionThis change will reduce the cost of construction where changes have already been made to features of a building to conform to olderaccessibility standards. Under the proposed changes to A117.1 significant cost would be required to conform to these requirements oftenin areas where upgrades have already been performed in areas such as toilet rooms to meet the barrier removal requirements of the ADAor because of alterations and change of occupancy under the I-Codes when that work had been done prior to the adoption of this newstandard.

Staff Note: If this code change is successful, the edition referenced for ICC A117.1 in Chapter 16 will remain the 2009 edition.

1204.1 Accessibility requirements. The provisions of Sections 705, 806 and 906, as applicable, shall apply tofacilities designated as historic structures that undergo alterations, unless technically infeasible. Where compliancewith the requirements for accessible routes, entrances or toilet rooms would threaten or destroy the historicsignificance of the building or facility, as determined by the code official, the alternative requirements of Sections1204.1.1 through 1204.1.4 for that element shall be permitted.

Exception: Type B dwelling or sleeping units required by Section 1107 of the International Building Code arenot required to be provided in historical buildings.

1204.1.1 Site arrival points. At least one accessible route from a site arrival point to an accessible entrance shall beprovided.

Exception: Type B dwelling or sleeping units required by Section 1107 of the International Building Code arenot required to be provided in historical buildings.

1401.2.5 Accessibility requirements. Accessibility shall be provided in accordance with Section 410 or 605.

SECTION 410 ACCESSIBILITY FOR EXISTING BUILDINGS

Reason: This change is written to move all of the accessibility requirements into a single section in new IEBC Section 303. New 303 iseditorial with no change in criteria or requirements and simply renumbers Section 410 to Section 303. All accessibility requirements forexisting buildings are placed in one section (303) allowing a focused and clear set of requirements for users to understand. In the existingIEBC, two of the three compliance methods (prescriptive and work area methods) have provisions for accessibility that are virtuallyidentical. In addition, the existing performance method refers to the accessibility provisions of the other compliance methods.

The intent of this change is a reorganization of accessibility provisions to avoid duplication of the same requirements in multiple codesections. The text of requirements is relocated, but the content of the moved sections is not changed. There is no intent to change coderequirements, only to recognize them. Note that Section 303.8.9 addressing dining areas is included only because that section has not yetbeen deleted from Chapter 7 as it was in current Section 410.

The identical provisions in all subsequent sections have been deleted.We understand that there are several proposals from BCAC to coordinate the provisions between Chapter 4 and 7. Our intent is thatthose proposals would be incorporated into the change. This move is editorial only.

Cost Impact: Will not increase the cost of constructionThis change simply consolidate the various crieria in the IEBC, and should not change the cost of construction.

Staff Note: The deletion to the committee scoping of [BS] to Sections B101.3, B101.4 and B102.2.3 is an errata and is not part ofthe proposal.

the alterations affecting the area of primary function.3. This provision does not apply to alterations limited solely to windows, hardware, operating

controls, electrical outlets and signs.4. This provision does not apply to alterations limited solely to mechanical systems, electrical

systems, installation or alteration of fire protection systems and abatement of hazardousmaterials.

5. This provision does not apply to alterations undertaken for the primary purpose of increasingthe accessibility of a facility.

6. This provision does not apply to altered areas limited to Type B dwelling and sleeping units.

Add new text as follows:

705.1.1 Compliance with accessibility. Accessible requirements for existing buildings shall comply with the 2009edition of ICC A117.1.

705.1.2 Extent of application. An alteration of an existing element, space, or area of a facility shall not impose arequirement for greater accessibility than that which would be required for new construction. Alterations shall notreduce or have the effect of reducing accessibility of a facility or portion of a facility..

705.2 Alterations affecting an area containing a primary function. Where an alteration affects the accessibility to,or contains an area of, primary function, the route to the primary function area shall be accessible. The accessibleroute to the primary function area shall include toilet facilities and drinking fountains serving the area of primaryfunction.

1012.8.2 Complete change of occupancy. Where an entire building undergoes a change of occupancy, it shallcomply with Section 1012.8.1 and shall have all of the following accessible features:

1. At least one accessible building entrance.2. At least one accessible route from an accessible building entrance to primary function areas.3. Signage complying with Section 1111 of the International Building Code.4. Accessible parking, where parking is provided.5. At least one accessible passenger loading zone, where loading zones are provided.6. At least one accessible route connecting accessible parking and accessible passenger loading zones to

an accessible entrance.

Where it is technically infeasible to comply with the new construction standards for any of these requirements fora change of group or occupancy, the above items shall conform to the requirements to the maximum extenttechnically feasible.

ExceptionExceptions:

1. The accessible features listed in Items 1 through 6 are not required for an accessible route to Type B units. 2. Accessible requirements for existing buildings shall comply with the 2009 edition of ICC A117.1.

Reason: Dramatic changes are being proposed in the next edition of the ANSI A117.1 standard that will accommodate a higher number ofindividuals. For example, the turning radius is being changed from 60" diameter to a 67" diameter, and clear floor space from 30"x48" to30"x52" and related access to features. While these changes are able to be incorporated into new construction relatively easily, existingbuildings that have been designed to conform with earlier standards or were modified to meet those earlier standards are likely to findthat full compliance will create problems. Even using provisions based on the technical infeasibility for compliance will still requirecompliance in some circumstances that aren't justifiable financially and physically.The Department of Justice in development of the 2010 ADA Standard allows for "grandfathering" of elements in an existing building thathave already been made to conform and are found to comply with the earlier ADA standard. The 2009 edition of A117.1 provides the mostcomprehensively structured provisions for compliance with the original ADA and HUD standard, which is why a specific reference to thatedition of the Standard for determining whether areas outside the specific alterations or change of occupancy must be modified.

In the other chapters (806.1, 906.1, 1012.8.1, 1105.1, 1204.1, 1401.2.5), by a reference back to Sections 410 and/or 705, this allowancewould be applicable to all existing buildings.

Bibliography: None

Cost Impact: Will not increase the cost of constructionThis change will reduce the cost of construction where changes have already been made to features of a building to conform to olderaccessibility standards. Under the proposed changes to A117.1 significant cost would be required to conform to these requirements oftenin areas where upgrades have already been performed in areas such as toilet rooms to meet the barrier removal requirements of the ADAor because of alterations and change of occupancy under the I-Codes when that work had been done prior to the adoption of this newstandard.

Staff Note: If this code change is successful, the edition referenced for ICC A117.1 in Chapter 16 will remain the 2009 edition.

2015 International Plumbing CodeRevise as follows:

403.1.2 Family or assisted-useSingle-user toilet facility and bathbathing room fixtures. FixturesThe plumbing fixtures located withinin single-user toilet facilities and bathing rooms, including family or assisted-use toilet and bathing rooms that are required by Section 1109.2.1 of the International Building Codeare permittedto be included in, shall contribute towards the total number of required plumbing fixtures for either the maleabuilding or female occupants in assemblytenant space. Single-user toilet facilities and mercantileoccupancies.bathing rooms, and family or assisted-use toilet and bathing rooms shall not be required to beidentified for exclusive use by either sex.

Reason: The use of single-user toilets has become increasingly beneficial system of providing not only better facilities, but more userfriendly facilities. A higher level of privacy is achieved, the facilities are typically better maintained by the users, and the efficiencies ofhaving unisex facilities where the users are of a dominate sex are significantly increased. Similarly, this code change removes the limitation of use for family or assisted-use facilities to mercantile and assembly occupancies. Families or persons requiring assisted-use can be found in various occupancies and should be allowed as providing required toilets. Currently, when there are multiple single-user toilets 50% of them are required to be accessible. If this is compared with the standardganged toilet rooms where there are multiple toilet fixtures, the number of accessible toilets and thus a greater number of useful toiletsby everyone will be increased by this change.

Cost Impact: Will not increase the cost of constructionThe single-user toilet room will reduce the cost of construction. Based on the minimum number of toilets, the larger general area requiredfor circulation for multi-fixtured toilet rooms can be eliminated in large part because areas such as sight-blocking and the multiplier forurinals for credit will be eliminated in multiple single-user toilet designs.
