Fence Regulations in Waukesha, WI

If you live in Waukesha or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. Waukesha has 3 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Retaining Walls

Waukesha caps an unengineered retaining wall at four feet under Municipal Code Sec. 22.17, the Preservation of Topography section. A taller wall needs a registered engineer, architect, or landscape architect to certify it will not collapse before the City will allow it between adjacent lots.

Key details: Unengineered wall cap: 4 feet maximum. Governing section: Municipal Code Sec. 22.17. Certification required for taller walls: Registered engineer, architect, or landscape architect. Small grade-cut standard: 2 ft or less: sod or masonry wall. Rip-rap slope limit: 1 ft vertical to 1 ft horizontal.

Building a retaining wall over four feet without the required engineer, architect, or landscape architect certification is a violation of Chapter 22 enforceable by the Zoning Administrator under Section 22.67, which lets the City, the City Attorney, or a damaged neighboring property owner seek injunctive relief. Because Chapter 22 does not set its own dollar penalty, violations fall under the Municipal Code's general penalty schedule in Section 25.05: not less than $10 nor more than $2,500 for a first offense plus prosecution costs, and $100 to $5,000 for each subsequent offense, with every day the wall remains noncompliant counted as a separate offense.

Material Restrictions

Waukesha bans barbed wire and electric fences almost everywhere: they are allowed only in the T-1 Temporary zoning district and only to contain livestock. Non-residential security fences can carry barbed wire on top, but only at least eight feet above grade, and a separate nuisance ordinance bans low barbed wire within five feet of the ground citywide.

Key details: Where barbed wire/electric fences allowed: T-1 Temporary district only. Purpose allowed: Livestock control only. Security fence barbed wire height: At least 8 feet above grade. Low barbed wire ban: Prohibited within 5 feet of ground citywide. Security fence approval: Plan Commission review required.

Installing a barbed-wire or electric fence outside the T-1 district, or a Security Fence with barbed wire lower than eight feet, violates Sec. 22.58(2) and is punishable under the general penalty schedule, Sec. 25.05: $10 to $2,500 for a first offense, $100 to $5,000 for repeat offenses. Barbed wire within five feet of the ground anywhere in the City is separately a public nuisance under Sec. 12.05(17), subject to City-ordered abatement.

This is one of the stricter rules in Waukesha's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Height Limits

The City of Waukesha regulates fences in residential districts under Section 22.58 of the Municipal Code, adopted under the city's zoning authority at Wis. Stat. Sec. 62.23(7). Standard residential fences may not exceed 6 feet in height. In the vision triangle at street intersections, street-alley intersections, and alley-alley intersections, fences are limited to 3 feet so they do not obstruct sight lines. Fences are not allowed in a required front yard, but are permitted in side and rear yards. No permit is required for residential fences, though all standards must be met.

Key details: Standard Max Height: 6 feet (residential side/rear yards). Vision Triangle Max: 3 feet. Front Yard Fences: Not allowed in required front yard. City Code Section: Waukesha Municipal Code Sec. 22.58. Enabling Statute: Wis. Stat. Sec. 62.23(7).

Installing a fence taller than 6 feet in a residential district, placing a fence over 3 feet within a vision triangle, or building a fence in the required front yard violates Section 22.58 and Chapter 22 of the Municipal Code. The Zoning Administrator may issue a notice of violation, require the fence to be lowered, removed, or relocated, and pursue forfeitures under the general penalty provisions of the Municipal Code. Encroaching onto a neighbor's property or into the public right-of-way may also expose the owner to civil action and removal at the owner's expense. Installing barbed wire or electric fencing in a residential district is also a zoning violation.

The Bottom Line

Waukesha's fence regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Waukesha is broadly strict or permissive.
