receptacle
Standard mounting heights for non-accessible lavatories, toilets and urinals
Indicate acceptable substrate and wet wall finish in the Notes box.
All plumbing must be on plumbing chase.
Consider sight lines from the entrance and between fixtures - avoid view of
urinals from entry/door, from other fixtures like lavatories, and avoid reflections
when possible
Accessible fixtures/clearances should not block path of travel or access to other
fixtures.
Do they ever ask for showers or ambulatory stalls in the restrooms?Do they ever ask for showers or ambulatory stalls in the restrooms?
Not in the restroom exercise. In space planning, you may have showers. For the
purposes of this exercise, neither an ambulatory stall or shower has been
required in the past 5 years.
The accessible stall must be fully accessible and not ambulatory.
In space planning you may have showers as part of the program, so is important
to know how these are drawn.

incorrect. Older versions may not accommodate a turning circle at entry.

layouts for restroom and space planning, but use the NCIDQ Building Codes,
especially regarding unobstructed turning circle. The turning circle should not
overlap a door swing or fixture on the exam.

Annotations & DimensionsUse the following annotation and dimension standards on yourdrawing and schedule.
Tag all fixtures and accessories per program, only 1 tag per same of each fixture
Note accessories as recessed, with no more than 4” projection into space
Templates
Qpractice recommends the ASID Washington State Templates especially for
restroom, but you can use any standard mass produced templates
Use 30" x 48" furniture shape or flip a 30” x 24” item like stove for clear floor
space
Mark most commonly used items with a Sharpie
Use wall mounted toilet symbol or omit the tank and pull sides back
Use urinal with elongated rim
Partitions
4-6” standard interior partitions
½” -1” stall toilet partitions - you must show thickness, a double line works
You can fur out, extend or add partitions to enclose or support lavatories or stalls
All plumbing must go on plumbing chase
Grab bars cannot go on toilet partitions, they require blocking within a standard
partition
Wet wall
Use cement board with porcelain or ceramic tile
Doors
4.5.2 ALL door openings shall be a MINIMUM of 36” [900 mm] wide with an 18”
[450 mm] clear space on the pull side of the door and a 12” [300 mm] clear space
on the push side of the door.
36” door gives a 34” opening
Use 36” accessible stall doors and restroom entry door
CAN use 34” in standard 36”W stall
Show push/pull clearances at accessible stall and restroom door if given (if not
given you do not need to add a door
Partitions & DoorsUse these standards for partitions and doors
Fixtures
Practice drawing these individual fixture components separately to build up your
hand drawing speed
Standard stall
Accessible stall with door swing in, version with door swing out
Urinal with accessible clear floor space
Toilets
Standard Stall
36” x 60” with 34” door - you should be able to fit this in all problems
30”W absolute minimum
Standard Toilet
15-18” centerline
Standard height 15”H to accommodate a range of people including children, and
differentiates from accessible toilet
Be sure to use the wall hung symbol on your template or omit the tank and pull
the sides back to the wall
Accessible Stall
5’ x 8’ with 60” turning circle, 36” door swings in, does not overlap turning circle
FixturesIncluding accessible and standard toilets, urinals, stalls, grab bars andlavatories
If less than 8’-0” then you may need to swing the door out when not in path of
travel
Dimension push and pull clearances
Must have 60” at rear wall and 56” at side wall
Toilet centerline at 16 - 18”, easiest to use 18” standard
Grab bars
Dimension both grab bars and distance from wall
Distance from wall is based on centerline of toilet, use 18" standard
Grab bar requires blocking, must be mounted on standard partition, not toilet
partition
Vertical grab bars
Vertical grab bars have not been listed as required in the NCIDQ Building Codes
in the 2015 and 2016 PDPs. In the 2015-2 PDP, the program requirements are as
listed in Part III C:
Grab bars, top of horizontal bar and centerline of vertical bar
but in Part II Program Requirements:
Grab bars as required by code.
The NCIDQ Building Codes accompanying 2015-2 did not require a vertical grab
bar.
This program instruction was not repeated in the 2016-1 PDP.
Vertical grab bars are NOT required in 2010 ADA Standards for Accessible
Design. See ADA 604.5 Grab Bars, and 605 Urinals.
While in IBC Chapter 11 Accessibility :
1101.2 Design. 1101.2 Design. Buildings and facilities shall be designed and constructed to beaccessible in accordance with this code and ICC A117.1.
ICC A117.1-2009 Accessible and Usable Buildings and Facilities requires an
additional vertical 18 inch bar located 39 to 41 inches (990 to 1040mm) off of the
back wall, and these may be required by state building codes, they are not
currently part of Americans with Disabilities Act Accessibility Guidelines.
The purpose of the NCIDQ Building Codes is to create a standardized set of
requirements for candidates across the US and Canada.
Qpractice recommends understanding this requirement so that you are able to
draw and dimension correctly, and check to see if the codes given with your
exam include this.
Accessible Toilet
16-18” centerline
18” centerline if using the standard 6” and 12” distance from wall on ASID
Template
17-19” H
Urinals
Urinals are not required by the plumbing codes in all occupancies. However, if
only one urinal is provided, neither the IBC nor the 2010 ADA Standards require
the urinal to be accessible. If two or more urinals are provided, then at least one
is required to be accessible (this is because there is an accessible stall).
For the NCIDQ Exam, always refer to program requirements
Urinal screens
Urinal privacy screen requirements vary in IBC - IPC and ADA.
It is best practice design to include a urinal screen.
When a privacy panel is used at an accessible urinal, it can be located either
inside or outside the clear floor space. If it is located inside the required clear
floor space, it cannot extend past the front edge of the urinal rim.
Depth of screen at standard urinal is 18”D, and can be no more than 6” past the
rim.
Standard Urinal
24” H
30” between panels will work for regular and ADA
Accessible Urinals
17” H
13 ½” min. D with elongated rim
Show the 30” x 48” clear floor space pulled up to rim of urinal
Lavatories
Standard or Accessible
30” centerline to centerline for multiple lavatories in continuous counter
30” minimum from centerline to toilet/water closet
Show faucet and lever handles, draw a quick "T"
Have not been required in the accessible stall, but always go by the program
instructions
Mount 34”H in counter
Mount 34” H wall hung for standard or accessible
Show single mirror over counter, or single mirror per each wall hung
Mirror with bottom edge starting at 40”H maximum for accessible lavatory
Mirrors above 34” counter with 4” backsplash, will typically be flush at 38”H
