Fence laws in Waukesha, Wisconsin
What the Waukesha municipal code says about fences, one topic at a time, with the section number and a link to the document behind every line. Where Waukesha sets no rule of its own, the Wisconsin rule is shown in its place and marked as such.
Fence laws in Waukesha, Wisconsin, question by question
The short version
- Who pays on the line
- Waukesha grants the boundary and then writes five conditions about what a fence may not interfere with, and the answer turns on what lies on or under the line. The figure is 0 feet, for setback from a property line.
- How tall
- Waukesha replaced its zoning code on September 1, 2026, and the new one puts fence height in a table keyed to the yard and the district, and the answer turns on the district, the yard and whether the code required the fence. The figure is 4 feet, for fence in a front or street side yard in the RN, MU and DC districts.
- Permits
- Wisconsin does not use the International Residential Code.
- Pool barriers
- Waukesha sets no statewide pool barrier rule. The chapters that were read are listed below. Cities and counties decide this one.
- Spite fences
- Wisconsin has a spite fence law and it covers hedges as well as fences. The figure is 6 feet, for height above which a maliciously built fence or hedge is a private nuisance.
- Measured from what
- Waukesha leaves the measuring rule to the council of a city, by ordinance.
- Corner lots
- Waukesha draws its vision triangle from the back of curb rather than from the property line, measured perpendicular to each intersecting right-of-way, access drive or driveway, and sizes it by what the fence is standing next to, and the answer turns on the kind of street or drive the triangle sits on. The figure is 10 feet, for minimum vision triangle depth at a driveway or interior access drive.
- Retaining walls
- Waukesha sets no rule for a wall that holds back earth. The chapters that were read are listed below. Cities and counties decide this one.
- Materials
- Waukesha sets materials in a grid, marking each one allowed or prohibited in each district, which is more granular than any list in this project, and the answer turns on the district, the yard and what the fence protects. The figure is 8 feet, for lowest height for barbed or concertina wire where it is allowed.
- Livestock
- Wisconsin lists the fences that count as legal and says nothing else does. The figure is 50 inches, for minimum height of a legal fence, measured at the posts.

Waukesha answers this, but the answer changes depending on what lies on or under the line.
Waukesha grants the boundary and then writes five conditions about what a fence may not interfere with. In all districts a fence may stand on or up to the property lines except where a specific setback is required, but it has to keep at least one foot from any public right-of-way, comply with the vision triangle, stay at least eighteen inches from underground utility access structures, drainage structures or pedestals for telephone, electric, cable or gas, leave access to above-ground utility structures and fire hydrants, and not inhibit the function of storm drainage. The eighteen inch figure is the unusual one and exists so a crew can get a lid up. Walls in residential districts are limited to decorative walls up to three feet set back at least two feet from front and street side lines, plus structural retaining walls needed for grade changes. Temporary deer fencing needs five feet of setback.
On or up to the property lines, except where specific setbacks are required,
The answer turns on what lies on or under the line.
- an ordinary lot line
- On the line. 0 ft
- a public right-of-way
- One foot clear. 1 ft
- buried utility access
- Eighteen inches clear. 18 in
- a decorative wall at the front
- Three feet tall, two feet back. 2 ft
Also on fences on the property line in Waukesha
- set in state lawWisconsin splits a fence on the property line in equal shares, but only where farming or grazing is involved. The duty runs between the people using two neighboring farm or grazing properties, and between the owners when one side is used that way. The fence stays in good repair all year unless both sides agree otherwise, and the two sides may agree to use markers instead of a fence. Wis. Stat. § 90.03Wisconsin · Statute
How tall can a fence be in Waukesha?
Compare fence height across all 50 states
Waukesha answers this, but the answer changes depending on the district, the yard and whether the code required the fence.
Waukesha replaced its zoning code on September 1, 2026, and the new one puts fence height in a table keyed to the yard and the district. In the four residential neighborhood districts and the mixed use and downtown core districts, a front yard fence is four feet, a street side yard is four, and interior side and rear yards are six. A street side fence may go to six if it is set back at least two feet from the street side lot line. Every other district gets six feet in front and eight everywhere else. Two entries sit outside the table. A fence surrounding an outdoor athletic court may reach fifteen feet provided it meets the opacity rules, and a fence the code itself requires for screening or buffering is exempt from the height table altogether. The agricultural, park and transportation districts are not covered by the height standards at all.
If a fence or wall is required by this Chapter for screening or buffering purposes, it shall be exempt from height restrictions.
The answer turns on the district, the yard and whether the code required the fence.
- a residential front or street side yard
- Four feet. 4 ft
- an interior side or rear yard
- Six feet. 6 ft
- every other district
- Eight feet behind the front. 8 ft
- an outdoor athletic court
- Fifteen feet. 15 ft
Also on fence height in Waukesha
- no rule, documents checkedWisconsin sets no limit on how tall a fence at a house can be. The six feet in the spite fence law is what starts a nuisance claim and not a cap, and that same law says a city or village may ban a fence under six feet. Chapter 90 describes legal fences for farm and grazing land without limiting height, and the Uniform Dwelling Code does not reach fences at all. Wis. Stat. § 844.10Wisconsin · Statute
Do I need a permit for a fence in Waukesha?

Wisconsin answers this in its own law. The words that do it are quoted below.
Wisconsin does not use the International Residential Code. It writes its own Uniform Dwelling Code in chapters SPS 320 to 325, which sets one set of building standards and inspections for one and two family homes and modular homes across the state. That code covers homes and their attached garages, porches, decks and stairways, and the word fence is nowhere in it. So a fence permit in Wisconsin is purely a local zoning question.
This one is Wisconsin law, not Waukesha law. All Wisconsin findings
The purpose of this code is to establish uniform statewide construction standards and inspection procedures for one- and 2-family dwellings and modular homes in accordance with the requirements of ss. 101.60 and 101.70, Stats.
Also on permits in Waukesha
- no rule, documents checkedThe fences and walls subsection sets location, height, materials, opacity, installation and maintenance and never mentions an application, a fee, an inspection or a height at which review begins. Two approvals appear nearby and neither is a fence permit. The City Engineer or a designee makes the final call on whether something in a vision triangle interferes with traffic visibility, and the same officer may approve a structure closer to a triangle in the mixed use and downtown core districts where safety precautions are provided. What the subsection does say, in place of a permit, is that its standards apply at all times regardless of whether new development, redevelopment or other site improvements are proposed, which makes them enforceable against an existing fence rather than only at the moment one goes up. The review procedures sit in a separate chapter of the zoning code that was not read for this page. Subsection 22.04(2)Waukesha · Zoning code
Pool fence requirements in Waukesha
Compare pool barriers across all 50 states
Waukesha law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.
Wisconsin sets no statewide fence rule for a pool at a house. The state pool chapter, SPS 390, says on its face that it covers public pools and water attractions only. The Uniform Dwelling Code, which governs one and two family homes, has no pool, barrier, fence or enclosure section in any of its six chapters. A pool fence at a home is a local matter.

Spite fence laws in Waukesha
Compare spite fences across all 50 states
Wisconsin answers this in its own law. The words that do it are quoted below.
Wisconsin has a spite fence law and it covers hedges as well as fences. Any fence, hedge or structure like a fence that goes over six feet with no need to, and was put up or kept up out of spite to annoy a neighbor, is a private nuisance, which means the neighbor can sue over it. The same section says it does not stop a city or village from banning a fence under six feet, so local rules still bite below that line.
This one is Wisconsin law, not Waukesha law. All Wisconsin findings
Any fence, hedge or other structure in the nature of a fence unnecessarily exceeding 6 feet in height, maliciously erected or maintained for the purpose of annoying the owners or occupants of adjoining property, shall be deemed a private nuisance.

How fence height is measured in Waukesha

Waukesha does not set this. It leaves it to the council of a city, by ordinance.
Wisconsin does not set this. The city does. The fence law in chapter 90 covers fences on a property line and what a fence viewer does, and it has no measuring rule in it anywhere. Section 62.23(7)(am) lets a city council set rules for the height, number of stories and size of buildings and other structures, and tells courts to read that power broadly in the city's favor. So the city ordinance sets the fence height and decides on its own what the height is taken from.
This one is Wisconsin law, not Waukesha law. All Wisconsin findings
the council may regulate and restrict by ordinance, subject to par. (hm) , the height, number of stories and size of buildings and other structures, the percentage of lot that may be occupied, the size of yards, courts and other open spaces
The code hands this to the council of a city, by ordinance, which is not published in the code itself.
Also on how height is measured in Waukesha
- no rule, documents checkedThe height table states four feet, six feet, eight feet and fifteen feet and never says what any of them is measured from. No grade is named for a fence, a berm is not addressed, and a fence on a retaining wall is not addressed, even though the same subsection allows structural retaining walls where grade changes make them necessary. Grade appears twice, and both times for a material rather than a height: barbed or concertina wire has to sit at least eight feet above grade where it is allowed, and curved or spear tip fencing has to sit at least six feet above the ground. What Waukesha measures carefully instead is how much can be seen through, with a second table setting maximum opacity by yard and district, fifty percent in a residential front yard, twenty percent in a street side yard rising to a hundred if the fence is set back two feet, and a hundred percent along interior side and rear lines.

Fence rules for corner lots in Waukesha
Compare corner visibility across all 50 states
Waukesha answers this, but the answer changes depending on the kind of street or drive the triangle sits on.
Waukesha draws its vision triangle from the back of curb rather than from the property line, measured perpendicular to each intersecting right-of-way, access drive or driveway, and sizes it by what the fence is standing next to. A driveway or an interior access drive gets ten feet. An alley, a local street or a collector right-of-way gets twenty. An arterial gets forty, which is one of the largest in this project. A state or federal highway takes whatever the state or federal standard requires rather than a figure in the code. The rule inside is written as a standard rather than a height: no building, structure, landscaping or other obstruction that interferes with traffic visibility may be located in the triangle, and where there is a question the City Engineer or a designee makes the final determination. In the mixed use and downtown core districts a structure may come closer where adequate safety precautions are provided and the City Engineer approves.
A vision triangle shall be measured perpendicular to and starting at the back of curb of each intersecting right-of-way/internal access drive or driveway for the minimum depth established in Table 22.04(4)(G).
The answer turns on the kind of street or drive the triangle sits on.
- a driveway or access drive
- Ten feet. 10 ft
- an alley, local or collector street
- Twenty feet. 20 ft
- an arterial street
- Forty feet. 40 ft
- what may stand inside it
- Nothing that interferes with visibility.
Also on corner visibility in Waukesha
- set in state lawWisconsin draws a triangle at every highway crossing outside a city or village, running 1,000 feet out along each center line, and bans danger causing advertising inside it. Section 86.191 then goes past signs. The road authority has to ask the owner of land inside that triangle to cut back whatever blocks the view across it, as far as that can be done, and to work out an arrangement that makes travel on both roads as safe as it reasonably can be. It is a duty to work it out with the owner rather than a fixed height, and it stops at the city line. Wis. Stat. 86.191(4)Wisconsin · Traffic code
Retaining wall rules in Waukesha
Compare retaining walls across all 50 states
Waukesha law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.
Wisconsin has no rule at all for a wall that holds back earth. It does not use the International Residential Code, so the model code line about a four foot wall never reaches this state. It writes its own Uniform Dwelling Code for one and two family homes, and both halves of that code were read end to end. Chapter SPS 320 is the paperwork half, covering the building permit, who issues it, inspections and exemptions, and the word retaining is nowhere in it. Chapter SPS 321 is the building half, covering digging, footings, frost protection, foundations, masonry walls and decks, and the word retaining is nowhere in it either. The code does have sections on digging next to a neighbor's land and on erosion control, and neither one sets a rule for a wall built to hold back earth. A permit for that kind of wall in Wisconsin is a local question.

Fence materials allowed in Waukesha
Compare materials across all 50 states
Waukesha answers this, but the answer changes depending on the district, the yard and what the fence protects.
Waukesha sets materials in a grid, marking each one allowed or prohibited in each district, which is more granular than any list in this project. Masonry, stone, decorative metal, architectural block, stained or painted or treated wood, wood composite and vinyl are allowed across every district except transportation. Smooth face block, above-ground electrified fencing and waste materials are prohibited everywhere, in every district, with no exception. Uncoated chain link without slats is allowed in the two lower density residential districts only in interior side and rear yards or around an athletic court. Barbed and concertina wire is allowed outright only in the transportation district and in the light, general, medium and outdoor manufacturing districts, where it has to sit at least eight feet above grade, and elsewhere it is permitted only to protect a utility facility. Curved and spear tip fencing is allowed in commercial districts only six feet or more above the ground.
Material is allowed in RN, MU, DC, GC, CC, and I districts only for the protection of any utility facilities and is otherwise prohibited.
The answer turns on the district, the yard and what the fence protects.
- masonry, stone, metal, wood or vinyl
- Allowed nearly everywhere.
- smooth face block and waste materials
- Prohibited in every district.
- barbed or concertina wire
- Manufacturing districts, eight feet up. 8 ft
- spear tips
- Six feet above the ground. 6 ft
Also on materials in Waukesha
- set in state lawWisconsin prints a closed list of legal fences and says the builds on it and no others count. Barbed wire and high tensile wire run through most of the list, always above a woven wire or board base, and one build is four or more barbed or high tensile wires at least 48 inches high on steel or wood posts. An electric fence is on the list too, with two extra strings attached. It takes two strands of tightly stretched wire fed by a standard approved electric or battery charger, with the top wire 34 to 36 inches up on insulated posts no more than two rods apart, which is 33 feet. And it counts as a legal fence only where the owners on both sides put their agreement in writing. Wis. Stat. 90.02(1m)(i)Wisconsin · Statute
Livestock and boundary fence law in Waukesha
Compare agricultural fencing across all 50 states
Wisconsin answers this in its own law. The words that do it are quoted below.
Wisconsin lists the fences that count as legal and says nothing else does. The list runs from woven wire of different widths with barbed or high tensile wire above it, to board fences on posts no more than eight feet apart, to a 48 inch fence of four or more barbed or high tensile wires. Whatever the build, the fence stands at least 50 inches high and its bottom sits no more than four inches off the ground, both measured at the posts.
This one is Wisconsin law, not Waukesha law. All Wisconsin findings
Fences shall not be less than 50 inches high, and the bottom of the fence shall be not more than 4 inches from the ground, measurements to be made at the posts.

Also on agricultural fencing in Waukesha
- set in state lawIn Wisconsin the fence on the line is the price of a damages claim. An owner who does not keep that fence in repair cannot collect for damage done by a neighbor's animals. Building it does not settle the other side either, because the owner of pigs, horses, sheep or goats still answers for damage those animals do inside the enclosure. Wis.

What this page does not cover
A city ordinance is not the only rule that reaches a fence. The zoning district a parcel sits in can change the height allowed on it, and so can an overlay district, a recorded easement, a fire hazard severity zone or a coastal zone. A homeowner association can be stricter than the city and nothing in the municipal code will say so. None of those appear here.
The rules above are the ones Waukesha publishes, plus the Wisconsin rules that apply where the city sets none. Fence laws in Wisconsin has the state layer in full.
