Palmdale, CA Building Safety: Building Permits (2026)

200, bars any person from erecting, constructing, enlarging, altering, repairing, moving, improving, removing, connecting, converting, demolishing or equipping any building, structure or automatic fire-extinguishing system, or performing grading or code-regulated landscaping, without first getting a permit from the Building Official or City Engineer. One exception: a single permit may cover a dwelling and one one-story accessory building under 600 square feet on the same lot. 2 separately bars owning, using, occupying or maintaining any unpermitted structure, meaning work done at any point without the required permit, regardless of how long ago it was built.

3 exempts specific minor work from permitting, including detached accessory structures like tool sheds, playhouses and greenhouses under 120 square feet and no more than 14 feet tall; chain link, wood, vinyl or wrought iron fences up to 8 feet (block walls to 6 feet); prefabricated water tanks under 5,000 gallons; retaining walls under 4 feet measured from footing to top; radio and TV antennae under 30 feet; flagpoles under 20 feet on single-family lots; and prefabricated above-ground pools under 5,000 gallons meeting slope and depth limits.

2; certain utility-connected work, like solar and main panel upgrades, requires a licensed contractor regardless of who owns the home. 4 if the work has not passed a foundation or first-phase inspection within one year, or is abandoned for a year, though a lapsed permit can be revived for 25 percent of the original fee if code requirements have not changed.
