Summary
Iowa City limits solid fences and walls to 8 feet anywhere over 10 percent solid, and cuts that to 4 feet inside a front setback on residential property, or on any lot within 50 feet of residential frontage, under zoning code section 14-4C-2L2. Corner lots get an added visibility-triangle rule for anything over 2 feet.
2. Location And Height Requirements: All fences, walls, and hedges located within a principal building front, side, or rear setback area or within five feet (5') of a lot line, are subject to the following location and height requirements: a. ... no portion of a fence or wall more than ten percent (10%) solid shall exceed eight feet (8') in height. The solidity is the percent of the fence over a random area which is made up of solid, opaque material, and which does not allow light or air to pass through. Retaining walls are exempt from the provisions of this paragraph. ... c. On corner lots, fences, walls, and hedges over two feet (2') in height must comply with the provisions of chapter 5, article D, "Intersection Visibility Standards", of this title. d. Fences and walls that exceed four feet (4') in height are not permitted in the principal building, front setback area on properties zoned residential or on properties located within fifty feet (50') of any property along the same frontage that is zoned residential. However, this height limit is increased to six feet (6') for lots with frontages along an expressway or an arterial street.

Full Breakdown
Section 14-4C-2L2, "Location And Height Requirements," governs every fence, wall, or hedge that sits within a principal building's front, side, or rear setback, or within 5 feet of a lot line, anywhere in Iowa City. The baseline rule is a solidity test: any portion of a fence or wall that is more than 10 percent solid, meaning made of opaque material that blocks light and air, cannot exceed 8 feet in height. Retaining walls are carved out of this solidity cap entirely.
Front yards on residential property get a stricter limit. A fence or wall over 4 feet tall is not allowed in the principal building's front setback area on a residential lot, or on any lot within 50 feet of another property along the same frontage that is zoned residential. That 4-foot cap rises to 6 feet only for double frontage or reversed corner lots that front an expressway or arterial street, recognizing that those lots face extra traffic noise and need more screening. A minor modification process is available to adjust the height of an entranceway gate within a front setback without a full board of adjustment case.
Corner lots carry a second, independent height trigger: any fence, wall, or hedge over 2 feet tall on a corner lot has to comply with the city's intersection visibility standards under chapter 5, article D, which keep sightlines clear at intersections regardless of the 4-foot or 8-foot limits that apply elsewhere on the same lot. Fences inside the riverfront crossings zones and the eastside mixed use district follow a separate frontage-type standard instead of these general rules.
Violations & Fines
A fence built taller than 8 feet where it is more than 10 percent solid, a front-yard fence over 4 feet on a residential lot, or a corner-lot fence over 2 feet that blocks the required sightline is a zoning violation of 14-4C-2L2. Under section 14-7C-5, that is a municipal infraction with a civil penalty of $250 to $750 per day under section 1-4-2D, and the city can also seek an injunction or abatement order to force the fence down or cut to height.
