Plan check correction: accessible toilet room clearances

Toilet rooms produce more accessibility comments than any other room type because every fixture has its own clearance and height. A plan at small scale cannot show them.

The comment asks for enlarged plans and interior elevations that dimension the turning space, the clear floor space at each fixture, water closet centerline and grab bars, and mounting heights. Clear it with dimensioned enlarged plans and elevations for every accessible toilet room, checked against the accessibility standard the jurisdiction enforces.

What the plans examiner is asking for

Turning space

A 60-inch circle or a T-shaped turning space inside the room. The 2010 ADA Standards let the door swing into the turning space, but not into the clear floor space at a fixture.

Water closet clearances

Centerline 16 to 18 inches from the side wall, and a clearance at least 60 inches wide and 56 inches deep, under 2010 ADA Standards Section 604.

Grab bars and accessories

Side and rear grab bar lengths and heights, and reach ranges to dispensers and mirrors.

Lavatories and doors

Knee clearance and pipe protection at lavatories, and maneuvering clearance at the door.

Comment

Provide fully dimensioned enlarged plans and elevations of accessible toilet rooms showing clearances, grab bars, and mounting heights.

Response

Revised as requested. Enlarged plans on A7.01 dimension the 60-inch turning space, water closet centerline at 17 inches from the side wall, and 60-inch-wide clearance. Interior elevations 2 to 5 on A7.02 show grab bar lengths and heights, lavatory knee clearance, and accessory mounting heights. Plumbing plan P2.01 updated for the relocated lavatory.

  2. Overlay the door

    Check that the door swing does not overlap the clear floor space required at any fixture.

  3. Match plumbing

    Confirm fixture locations on the plumbing plans match the architectural enlarged plans.

Questions, answered

Accessible toilet rooms: questions

Which accessibility standard applies to toilet rooms?

It depends on the jurisdiction. Many cities enforce IBC Chapter 11 with ICC A117.1; California uses CBC Chapter 11B; the 2010 ADA Standards apply as a federal civil rights requirement. The plans should name the standard used.

How wide is the clearance at an accessible water closet?

Under the 2010 ADA Standards Section 604.3.1, the clearance is at least 60 inches wide measured from the side wall and 56 inches deep measured from the rear wall. Toilet compartments have their own dimensions.

Do all toilet rooms need to be accessible?

New construction generally requires accessible toilet rooms, with specific exceptions. Alterations follow separate rules for which rooms must be made accessible. Check the adopted standard.
