Martinez, CA Swimming Pools & Spas: Pool Permits (2026)

Under Martinez Municipal Code Title 15 and the California Building Code, construction of any permanent in-ground pool, above-ground pool deeper than 18 inches, or spa requires a building permit from the Martinez Building Division. Required submittals include site plan showing setbacks (typically 5 feet from side and rear property lines, plus distance from sewer laterals and structures), pool plan and cross-section, barrier details, drainage plan, and structural calculations for decks and retaining walls. Electrical permits cover bonding and grounding per NEC Article 680, and plumbing permits address circulation, backwash discharge, and backflow prevention. Grading permits are required if excavation exceeds 50 cubic yards or changes drainage patterns. Inspections include pre-gunite (steel and bonding), deck pre-pour, final plumbing, final electrical, and final barrier/safety inspection. Pool construction must be complete including safety barriers before water is added. Permit fees are based on valuation and typically total $1,500-$3,500 for a residential pool including plan check. Work without permits results in double fees, required exposure of covered work for inspection, and potential removal orders. Anti-entrapment drain covers meeting the Virginia Graeme Baker Act are required.
