Iowa City, IA Fence Regulations: Permit Requirements (2026)

Iowa City takes a permit-only-when-needed approach to residential fences. The Building Division's published Fence Information and Guidelines (April 7, 2021 version) lists five specific permit triggers, all of which require a Residential Building - Accessory Structure permit: (1) fences over 6 feet in height; (2) electric fences (regardless of height); (3) barbed wire fences (regardless of height); (4) retaining walls over 4 feet in height measured from the top of the footing to the top of the wall; and (5) any retaining wall of any height that supports a surcharge (such as a driveway or building load above the wall) or impounds flammable liquids. Standard residential fences of 6 feet or less in a side / rear yard, or 4 feet or less in a front yard, that are not electric and not barbed wire do not require a permit - but they must still comply with the zoning standards in 14-4C-2L: height caps, the 2-foot setback from alley / street right-of-way, and the Article 14-5D visibility triangle. Permit applications go through the City's CSS (Customer Self-Service) online permitting portal at icgov.org/permitinfo; the Building Division at City Hall, 410 East Washington Street, processes them. Detailed plans showing dimensions and structure elements (post size, post spacing, footing depth, board layout) are required. The City does not survey property lines - applicants must rely on a licensed land surveyor for line determination, and the application instructs callers to contact the Johnson County Recorder for private covenants and Iowa One Call (811 or 800-292-8989) before any digging. Easement restrictions are checked through Development Services at (319) 356-5120. Fences in historic districts or conservation districts (Brown Street, College Green, East College, Goosetown / Horace Mann, Jefferson Street, Longfellow, North Side, Summit Street, Woodlawn, and the College Hill Conservation District) require additional Historic Preservation Commission certificate of appropriateness review before installation of any visible exterior fence.
