Before You Build in Lincoln, CA: Permit & Rule Checklist (2026)

Under the California Building Code adopted by Lincoln Municipal Code Title 15, retaining walls over 4 feet measured from the bottom of the footing to the top of the wall, or any retaining wall supporting a surcharge such as a driveway, slope, or structure, require a building permit and engineered drawings from the City of Lincoln Building Division.

New or remodeled residential pools and spas in Lincoln must comply with California Health and Safety Code section 115922 (the Swimming Pool Safety Act), which requires at least two of seven listed drowning-prevention safety features, including an isolation enclosure at least 60 inches high with a self-closing, self-latching gate. Lincoln Building inspectors enforce this at final inspection.

In Lincoln, fences 6 feet or shorter in side and rear yards generally do not need a building permit, but fences over 6 feet trigger a building permit through the Community Development Permit Center. Yard setback and front-yard height limits are set by the Title 18 Zoning Code, administered by the Planning Division.

Lincoln does not impose a city-wide ban on common residential fence materials (wood, vinyl, masonry, chain link), but fences over 6 feet must be permitted and meet the California Building Code wind, structural, and footing requirements adopted by Title 15 of the Lincoln Municipal Code. Barbed wire and electrified fencing are restricted to non-residential uses under typical Title 18 zoning practice.

Lincoln does not have a city-specific shared-fence cost ordinance. California Civil Code section 841 (the Good Neighbor Fence Law) presumes adjoining property owners share equally in the reasonable cost of constructing, maintaining, and replacing a boundary fence, and requires 30 days written notice to the neighbor before incurring costs.

A building/zoning permit is generally required in Lincoln for fences over 6 feet or masonry/retaining walls; pool barrier fences must meet the California Building Code. Standard residential fences at the height limit may be permit-exempt.

Above-ground pools in Lincoln must meet the same barrier rules as in-ground pools and require a building permit if water depth exceeds 18 inches or the pool is connected to permanent plumbing/electrical.
