040. 1 of that chapter requires any owner or authorized agent who intends to construct, enlarge, alter or repair a building or structure to first make application to the Building Official and obtain a permit; work done without one is a code violation and can be deemed an unsafe structure. 2 lists narrow permit exemptions, and item 8 under "Building" is the only pool-specific carve-out: a prefabricated pool accessory to a single-family (Group R-3) home that is less than 18 inches deep, holds no more than 5,000 gallons, and sits entirely above ground.
Every other residential pool, in-ground or a larger above-ground unit, needs a permit. 1 to add "swimming pools" to the list of Group U accessory occupancies alongside private garages, retaining walls and sheds, meaning a completed pool must conform to the fire and life-hazard construction standards for that occupancy class. 13, stating its purpose is to prescribe regulations protecting public health and safety and to establish minimum regulations for pools and spas citywide; that chapter's amendments cap pool enclosure gates and doors at four feet in width.
Violations & Fines

Installing a pool gate or door wider than the four-foot maximum set under the 2024 International Swimming Pool and Spa Code amendments is also a violation, correctable before final inspection and issuance of a certificate of occupancy.
