Regardless of how many square feet you have, or the number of seats that your fire regulations may permit, be sure to also check with all the building codes to determine the level at which you will be required to also add a sprinkler system. The determining factor is usually the number of seats approved by the Fire Marshall (or equivelent). Adding sprinklers would be expensive… so if, for example, sprinklers are required after 80 or more seats are approved…you would then simply seek only 79 seats to avoid the added costs. This potential issue is also something that could be discussed with your landlord when reviewing buildout paramaters and rent concessions.
