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

Pool fences in Pittsburg must meet California Health & Safety Code §115920-115929 standards: minimum 60-inch height, self-closing and self-latching gates, no climbable features, and two approved safety features for pools built after 2007.

Hedges acting as boundary barriers in Pittsburg are subject to the same height limits as fences: 6 feet in side/rear yards and 3.5 feet in front yards. Hedges in the sight-distance triangle at driveways and corners must be kept low for traffic visibility.

Pittsburg limits fence height to 6 feet in side and rear yards and 3.5 feet in front yards under PMC Title 18 zoning. Fences over 6 feet require a building permit, and corner lots have additional sight-distance triangle restrictions.

Retaining walls in Pittsburg over 4 feet in height (measured from bottom of footing to top of wall) or supporting a surcharge require a building permit and engineered design under California Building Code Section 105. Walls under 4 feet and not supporting surcharge are typically exempt.

All pool and spa drains in Pittsburg must comply with the federal Virginia Graeme Baker Pool and Spa Safety Act and the California Pool and Spa Act. Single main drains must have anti-entrapment covers certified to ANSI/APSP-16, and pools built after 2007 must include either dual main drains or an automatic pump shut-off system to prevent suction entrapment. Commercial and public pools face more rigorous inspection and drain certification requirements.

Pool barriers in Pittsburg are governed by California Health and Safety Code sections 115920 through 115929 (the Swimming Pool Safety Act) as enforced through the California Building Code. Any new pool or spa or remodel equipped to be filled with water more than 18 inches deep must include at least two of seven approved drowning prevention safety features, with an enclosing barrier at least 60 inches high being the most common. Gates must be self-closing and self-latching with latches at least 54 inches above the ground.

Pittsburg Municipal Code Chapter 15.56 applies to any pool deeper than 18 inches or larger than 250 square feet, including above-ground pools. A 5-foot enclosure with openings no larger than 4 inches and a self-closing, self-latching gate is required. California's Pool Safety Act (Health and Safety Code 115921 et seq., as amended by SB 442) layers on at least two of seven approved drowning-prevention features for new or remodeled residential pools.
