STATE BUILDING CODE INTERPRETATION NO. 98-17
 
CODE: 1997 Uniform Building Code (UBC)
SECTION:  Chapter 29 Plumbing Systems
QUESTION:  1.  Based on Table 29-A, my calculation of minimum restroom fixture requirements for a 1250 seat multiplex theater results in four water closets for males and twenty-one water closets for females.  Is this calculation correct?
 
2.  If the answer to question number one is “yes”, are there other ways to determine minimum fixture requirements?
ANSWER:  1.  Yes, only if the facility has "limited time for fixture use (intermissions)".  If there are no "intermissions", then refer to Sections 2902.1.1 or 104.2.8, where the building official should decide, based upon sufficient supportive information provided by the designer for the most appropriate number of fixtures.
 
2.  Yes.  Refer to 104.2.8.
SUPERSEDES: None
