Antioch's Swimming Pools & Spas: The Rules That Matter

Every city handles swimming pools & spas a little differently. In Antioch, California, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Pool Permits

A City of Antioch building permit is required before constructing or installing any in-ground or permanently installed above-ground swimming pool, spa, or hot tub, and the project is reviewed under the 2025 California Building, Residential, Electrical, and Plumbing Codes.

Key details: Permit required: Yes, for all in-ground and permanent above-ground pools/spas. Adopted codes: 2025 California Building, Residential, Electrical, Plumbing Codes. Submittal portal: Antioch Civic Access (Enterprise Permitting & Licensing). Issuing department: Building Services Division, 200 H Street, 2nd Floor. Contact: 925-779-7065; Building@antiochca.gov.

Constructing or installing a pool without a permit is a violation of the adopted California Building Code and Antioch Municipal Code. Stop-work orders may be issued, work already performed can be required to be exposed for inspection or removed, and the project will not be finalized until plan review, fees, and inspections are completed. Code-enforcement penalties under the Antioch Municipal Code may also apply.

Fencing & Safety Requirements

Antioch enforces the California Swimming Pool Safety Act through its adoption of the California Residential Code: any new or remodeled residential pool, spa, or hot tub must be enclosed by a qualifying barrier and provide at least two drowning-prevention safety features.

Key details: State authority: Cal. Health & Safety Code sections 115920-115929 (Swimming Pool Safety Act). Local adoption: 2025 California Building/Residential Codes, effective Jan 1, 2026. Pool depth trigger: Any pool, spa, or hot tub holding water over 18 inches deep. Enclosure height: 60 inches minimum (HSC section 115923). Drowning prevention features required: At least 2 of 7 qualifying features per HSC section 115922.

The Building Services Division (200 H Street, 2nd floor, 925-779-7065) will not finalize or close out a pool/spa permit until field inspection confirms the barrier and drowning-prevention features comply with the California Residential Code and HSC sections 115922-115923. Unsafe or non-compliant pools may also be cited as a public nuisance under the Antioch Municipal Code.

The Bottom Line

Antioch's swimming pools & spas rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Antioch is broadly strict or permissive.
