Greetings, I need clarification regarding allowable stories and area. The code used is the 2019 California Building Code.
We are doing a tenant improvement to an existing 12,200 sq.ft. 2 story Type V-B unsprinklered non-separated mixed use building. The occupancy groups will be A-2, M and B. I understand that the most restrictive occupancy will be A-2 and further that we will at least need to add fire sprinklers. Checking Table 506.2 for area, A-2 SM without height increase allows 18,000 sq. ft. Table 504.4 for stories, A-2 S without area increase allows 2 stories. The building basically has 100 feet or more on three sides and 50 feet on one side. It appears that we fall within the allowable area and height shown in those tables for A-2 occupancy.
However when using the UpCodes calculator, one data input asks "Does your plan incorporate the sprinklered height increase or the area increase from Tables 504.3, 504.4, and 506.2?" None is not a selection option so I have to enter one of the choices. Either choice returns that the building is not compliant, either too large or too many stories.
What am I missing? What do I need to do to make the existing building be code compliant based on the information listed above?
Thank you for any advice.
