Full Breakdown
Any pool or spa installation in SF needs a building permit. The application requires: structural design stamped by a licensed engineer (pools count as structural improvements), electrical and plumbing plans, barrier/enclosure details meeting H&S 115920 (60-in fence, self-closing gate, etc.), a site plan showing setbacks (typically 5 ft from property lines), and evidence of compliance with Energy Code (pump timers, solar requirements under Title 24). Plan check takes 6-12 weeks given SF's small pool volume and complex hillside sites. Inspections required: excavation, pre-gunite/steel, pre-plaster, electrical bonding, and final barrier/safety. In-ground pools typically cost $80K-$200K+ in SF due to hillside engineering, small yards, and labor costs. Above-ground pools over 24 inches deep also require permits. Permits expire after 180 days without inspection. Unpermitted pools discovered during title search or neighbor complaint can be cited and require retroactive permitting or removal, and may block resale.
