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

Above-ground pools in unincorporated Calaveras County are treated under the same County rules as in-ground pools. The Building Department's permit-exemption list states 'Prefabricated swimming pools less than 24 inches deep' do not require a building permit. An above-ground pool deeper than 24 inches requires a building permit through the County Building Department under the 2022 California Building Code. Regardless of permit status, the Zoning Code (Section 17.16.130) regulates any manmade body of water more than 18 inches deep: the inside wall of the water-containing portion must be at least five feet from any property line, and related above-ground equipment such as pumps and filters must meet the standard zone setback or be at least five feet from the property line, whichever is less. Because an above-ground pool wall can itself serve as part of the barrier, owners should verify with the Building Department how the California Swimming Pool Safety Act (Health and Safety Code 115922-115923) applies; when a permit is issued, the pool still must provide at least two approved drowning-prevention features, and any access ladder or steps may need to be removable or guarded. Decks built around an above-ground pool may trigger their own permit unless they are under 200 square feet, less than 30 inches above grade, and free-standing. Confirm setbacks and barrier details with the County before installation.
