Pool Permits
Portland requires a building permit to install any in-ground swimming pool and most above-ground pools, with review under the Maine Uniform Building and Energy Code (MUBEC). A separate plumbing permit is required if the pool ties into the water supply and an electrical permit is required for heaters, pumps, and lighting.

Every outdoor swimming pool in Portland must be enclosed by a barrier at least 48 inches high under the 2015 IRC (adopted via MUBEC), with no openings allowing a 4-inch sphere to pass and no more than a 2-inch ground clearance. State law 22 M.R.S. §1632 separately mandates a fence around every pool, with gates capable of being securely fastened when not in use.

Above-ground pools in Portland generally require a building permit and must meet the 48-inch barrier rules under the 2015 IRC. State law 22 M.R.S. §1632 exempts portable above-ground pools with sidewalls at least 24 inches high from the separate fence requirement, but the IRC barrier provisions still govern any pool capable of holding 24+ inches of water.

A plumbing permit is required for any potable-water connection and an electrical permit for heaters, pumps, and lighting. Hot tubs on raised decks may trigger structural review.
