The new hotel building is a 4-story type VA that sits on a type I podium used for parking and entry lobby. There is also 1-1/2 levels of basement parking. The second floor has a restaurant and guest units on the same level. Because of the sprinklers, we are able to raise it 1-story and an additional 12,000 sf. Will the sprinkler help per floor to increase the allowable area (table 503) which is 12,000 to a much higher figure for the sum of ratios calculation? Based on 506.4, the sum of ratios for Group A & R and some others cannot exceed 2 in multi-story buildings. The numbers add up to more than that (3.25 to be exact) especially adding one more floor due to sprinklers. Can you subtract areas that are non-occupiable such as restrooms, corridors, and stair/ elevator shafts? It's hard to get a sum of two. Is it a catch 22?
