The Fire Marshal’s Office reviews development plans to ensure projects meet the minimum code requirements for adequate fire apparatus access and water supplies. Building plans are reviewed to ensure projects meet the fire and building codes for fire/life safety requirements for fire rated construction, occupant egress systems, fire sprinkler systems, and fire alarm systems.
