3,000 sq. ft. exemption

[Mech]

'09 IBC

1104.4 Multilevel buildings and facilities

Exception 1: An accessible route is not required to stories and mezzanines that have an aggregate area of not more than 3,000 sq ft . . .

Is the 3,000 sq ft based on the outside or the inside face of the exterior wall?

Thanks

inside face of the exterior walls (502.1, although mezzanines do not count towards building area)

Why does the link for your "3,000 square feet" link to Home Depot?

Net or gross depends on the occupancies involved for the building code.

Use your best judgement when it comes to ADA.

I would think that the aggregate area is net square footage of each space.

If you have five mezanines in a 10,000 square foot office and they are each 650 sq. ft. at a total of 3,250 sq. ft., then would you have to require that each one be accessible?

Yup! They sure would need to be accessible

gbhammer,

I hope to never see a scenario like you painted as the exiting costs and problems would be a designer's worst night mare IMHO

What about 1104.4, Exception 2?

Levels that do not contain accessible elements or other spaces as determined by Section 1107 or 1108 are not required to be served by an accessible route from an accessible level.

I just made a separate post about this exception. http://www.inspectpa.com/forum/showthread.php?7663-Accessible-Route-exceptions&p=73727#post73727
