Any interior or exterior remodel of any portion of the space will require an architectural review to ensure life safety criteria as outlined in the IEBC are met. This includes a remodel of a kitchen, bar, dining areas, storage areas, basement, entrances or exits, ramps, platforms, equipment, bathrooms, or any accessibility features. Your project will likely need to be issued a new maximum occupant load certificate for posting publicly in your space.
When the remodel includes electrical work, new or upgraded mechanical equipment, or plumbing work, you will also need electrical, mechanical, and plumbing reviews. All remodels need an SUDP, as even small changes could impact a site's sewer use or drainage.
Any remodel to a restaurant or commercial kitchen will receive a health review.
