BACKGROUND:

I have an existing non-permitted 1,721 sf physical therapy/office space in CA, which we are preparing plans to legalize. The space has a single uni-sex restroom (non-ada compliant), 3 offices, reception, utility room and 658 sf of exercise area "gym". The area is calculated using inside of exterior walls.

The plan checker thinks two restrooms are needed, one for each sex. He's agreed not to classify the "gym" as an A group.

Per Table A the Occupant Load Factor for Group B or I is 200: (B being the closest group to the actual facility)

1,721sf/200 = 8.6, call it 9

Using 2010 CPC Chap 4, sec 412.3 Separate Facilities, Exception 2 - In occupancies serving 10 or fewer people (occupant load) one unisex restroom is permitted.

Our load is less than 10, thus the existing ui-sex restroom should be permitted - CORRECT??

Also, when determining the Load factor can walkways or paths of travel in a space that has no constructed corridors be eliminated when determining the area, since these are "accessory" spaces like a restroom, corridor or space beneath stairs?

I appreciate your responses.

Can't help you out on Cal code stuff, but wanted to welcome you to the forum....

OL for B is 200 per?
 
Women aren't going to like sharing the can at a physical therapy office. Once will be more than enough....but wait a minute, this is a successful business....I guess it's just the women I know....they're what you might call delicate.

The idea of deleting walkways and paths of travel from the area doesn't sound right. If there are no walls forming a hallway or corridor then the space is part of the area for the purpose of calculating an occupant load. If it were possible to delete a "walkway" who's to say what the boundary of the walkway is?

From the info you supplied I agree only one unisex restroom is required

FYI the IBC number is 15 before two restrooms are required

Welcome to the Forum. Yes, you are correct, Section 412.3 allows for an exception with an occupant load of 10 or fewer to be served by one unisex facility. And yes, you calculated the occupant load correctly.
 
Correct, the plan checker agreed.. I'm not sure what he was referencing in his head, given the clarity of the code in this case.
