Before You Build in Berkeley, CA: Permit & Rule Checklist (2026)

California Health and Safety Code 115920 et seq. requires 60-inch pool barriers with self-closing self-latching gates, enforced in Berkeley through building permit inspections.

Berkeley requires a building permit for fences over 6 feet tall and most retaining walls over 4 feet, with zoning review for all fences near public right of way.

California Civil Code 841 (Good Neighbor Fence Act) governs shared fence costs in Berkeley, presuming equal cost sharing with 30 days written notice before construction.

Retaining walls over 4 feet in Berkeley require a building permit and engineered design, with extra scrutiny in Berkeley Hills where seismic and slope stability are critical concerns.

Berkeley limits fences to 6 feet in rear and side yards and 3.5 feet in front yards under BMC zoning, with hillside and view-corridor considerations in the Berkeley Hills.

Hot tubs and spas in Berkeley over 18 inches deep need a permit and barrier compliance, but a locking safety cover meeting ASTM F1346 can substitute for fencing.

Berkeley pools must include anti-entrapment drain covers under the VGB Act, GFCI-protected electrical, and approved chemical storage, in addition to state barrier requirements.

Berkeley enforces California H&S 115920 requiring pool barriers at least 60 inches high with self-closing, self-latching gates and at least two additional safety features.

Berkeley requires a building permit for any pool or spa over 18 inches deep, with plan review for structural, electrical, and plumbing work under the California Building Code.

Above-ground pools in Berkeley over 18 inches deep need a building permit and full compliance with barrier, electrical, and setback rules — structure walls alone do not satisfy the fence requirement.

Berkeley allows garage-to-ADU and garage-to-JADU conversions under BMC 23.306, consistent with California Government Code §65852.2. No replacement parking is required when a garage is converted to an ADU, and the existing garage's setbacks are preserved for the converted footprint.

Berkeley regulates ADUs and JADUs under Berkeley Municipal Code Chapter 23.306. One ADU plus one JADU is allowed per single-family lot citywide (Hillside Overlay allows one ADU OR one JADU). New detached ADUs are limited to 16 feet in height, with a 4-foot minimum side and rear setback, and JADUs are capped at 500 sq ft within the existing dwelling.

Tiny homes on foundations qualify as ADUs under Berkeley and state law. Tiny homes on wheels (THOWs) are not permitted as permanent dwellings; RV-parked living is prohibited.

Sheds under 120 sq ft and 12 ft tall are permit-exempt in Berkeley. Larger structures need permits, fire zone sheds must meet WUI standards, and setbacks apply to all sheds.

Carports require building permits and must meet setbacks. Front-yard carports are restricted; fire zone carports need WUI-compliant materials.

Berkeley bans all outdoor burning of vegetation, yard waste, and debris. BAAQMD and BMC 9.24 prohibit open burning citywide; no burn permits are issued for residential properties.

Berkeley bans virtually all open flame and wood-burning fire pits outdoors due to BAAQMD Regulation 6 and Very High Fire Hazard Severity Zone (VHFHSZ) restrictions. Only fully enclosed gas appliances are tolerated.

Removal of Coast Live Oaks, Redwoods, and trees 12+ inches DBH requires a city permit with replacement. Street tree removal needs Parks approval; unauthorized removal triggers fines up to 10,000 dollars.

Private trees may be pruned by owners, but protected species and street trees require city approval. Fire zone pruning is mandatory under PRC 4291 defensible space rules.
