Sierra County, CA Swimming Pools & Spas: Above-Ground Pools (2026)

Sierra County does not have a separate ordinance carve-out for above-ground pools. The County's building-permit exemption list in Sierra County Code section 12.04.030 incorporates the exemptions of CRC R105.2 and CBC 105.2 but does not specifically exempt above-ground pools, so a building permit is generally required where the adopted California Residential Code thresholds are met (the CRC treats pools and spas above a certain water depth as requiring a permit and barriers). The same California Swimming Pool Safety Act standards apply: under Health & Safety Code section 115922, a new above-ground pool or spa serving a single-family home must include at least two of seven drowning-prevention features. The walls of an above-ground pool can count toward an enclosure only where they meet the barrier standards of Health & Safety Code section 115923, and any ladder or steps must be removable, lockable, or otherwise secured against unsupervised access. Electrical bonding and any pump and filter wiring are reviewed under the adopted California Electrical Code (Sierra County Code section 12.04.080). Owners in unincorporated communities should confirm permit applicability and setback placement with the Sierra County Building Inspection Division before installation.
