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

A building permit from the City of Westminster Building Division is required before constructing a swimming pool or spa, per the City's Building Division information. Westminster adopts the California Building, Residential, Electrical, Plumbing, and related codes (with local amendments) through Title 15 of the Westminster Municipal Code; Chapter 15.08 sets out the adopted Building Code. According to the Building Division, most accessory projects with plans based on City standards — such as pools and spas — can be checked over the counter and the permit issued the same day, while custom or engineered designs go through standard plan review. The permit covers the pool shell, the required safety barrier, and associated electrical and plumbing work. Westminster does not publish a separate pool-specific ordinance chapter; the technical safety standards come from the adopted California codes and the state Swimming Pool Safety Act (Health and Safety Code sections 115922–115929), which apply to new and remodeled pools at single-family homes statewide. The Building Division can be reached at (714) 548-3254. The City's accessory-structure standards in Municipal Code section 17.400.130 also govern the placement of related items such as pool slides and decks. Always confirm current submittal requirements and fees with the Building Division before starting work.
