Blaine, MN Swimming Pools & Spas: Above-Ground Pools (2026)

Blaine addresses above-ground pools through the same Chapter 18, Article IX framework that governs all pools. The permit exemption is narrow: "private residential prefabricated pools entirely above ground, which do not exceed both 5,000 gallons and 24 inches in depth" do not need a building permit. A pool that exceeds either the gallon or the depth threshold requires a permit and the standard inspections, which for above-ground pools include gas piping air test, equipment location, fence/barrier, and final. Critically, the city emphasizes that even permit-exempt pools must still include the required barrier/fencing, so a larger inflatable or framed above-ground pool cannot simply be set up without an enclosure. The barrier rules are the same as for in-ground pools: a non-climbable barrier at least 48 inches high from finished ground level, no more than a 2-inch gap at the bottom, a 3-foot non-climbable horizontal zone, and materials able to resist a 200-pound lateral load. Because the wall of an above-ground pool can itself serve as part of the barrier in many jurisdictions, homeowners should confirm during permitting whether ladder removal or a self-closing gate at the steps is required to keep the pool inaccessible when not in use. Hot tubs, spas, and inflatable pools are all treated as pools. A site survey is required at application so the pool's placement can be reviewed.
