Brentwood FAQ
Do I need a permit for an above-ground portable spa?
Yes. Portable above-ground spas still require a building permit; submittals must include the UL listing with installation requirements, and inspections include rough electrical and a final inspection.
What setback applies to above-ground pools?
Above-ground pools or spas may have greater setbacks than the 5-foot minimum required for in-ground pools and may require administrative review by Planning staff based on lot zoning and orientation. Contact Planning at 925-655-2700 for site-specific guidance.
Is Environmental Health approval needed for a backyard pool?
Sanitary or Environmental Health approval is required prior to issuance of a building permit, particularly where parcels are served by septic systems. Multifamily residential pools are classified as commercial and require additional Environmental Health permitting.
