Fence laws in Milwaukee, Wisconsin
What the Milwaukee municipal code says about fences, one topic at a time, with the section number and a link to the document behind every line. Where Milwaukee sets no rule of its own, the Wisconsin rule is shown in its place and marked as such.
Fence laws in Milwaukee, Wisconsin, question by question
The short version
- Who pays on the line
- The first sentence of the fence rules grants the whole lot, and the answer turns on whether the line is shared with a neighbor or with a street. The figure is 0 feet, for setback from a residential property line.
- How tall
- Milwaukee sets four feet as the base in both the front yard and the side yard, which is stricter than most cities on the side, and then sells the extra two feet for openness in three different ways, and the answer turns on the yard, the material and how open the fence is above four feet. The figure is 4 feet, for fence in a front or side yard.
- Permits
- The zoning chapter sets no general fence permit and no fee, and the answer turns on what the fence is for and where it stands.
- Pool barriers
- Milwaukee 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
- Milwaukee answers the sloping boundary question by pointing at the neighboring lot rather than at a grade. The figure is 10 feet, for height a decorative gate or trellis may reach above the fence limit.
- Corner lots
- Milwaukee sizes its vision triangle by zoning district and lets it disappear entirely in the densest ones, and the answer turns on the zoning district and whether the object is opaque. The figure is 25 feet, for vision triangle leg in the RS1 to RS4 and similar districts.
- Retaining walls
- Milwaukee 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
- Milwaukee bans three materials in one sentence and names no others, and the answer turns on the material and how open the fence is.
- 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.

Milwaukee answers this, but the answer changes depending on whether the line is shared with a neighbor or with a street.
The first sentence of the fence rules grants the whole lot. Fences are permitted anywhere on a lot in a residential zoning district, including along property lines, and the paragraph says the word fence includes a wall or similar structure, so the permission covers both. No setback figure appears for an interior line anywhere in the section. Distance only enters as a way of buying height, with a side yard fence allowed six feet if it stands more than ten feet from the side lot line. Two limits sit at the street rather than at the neighbor. A fence along a side street or rear street property line is held to four feet, and a fence or retaining wall may extend into the public right-of-way only as chapter 245 allows or under a special privilege granted by the common council, which is a grant of public land rather than a setback.
Fences shall be permitted anywhere on a lot in a residential zoning district, including along property lines.
The answer turns on whether the line is shared with a neighbor or with a street.
- an interior lot line
- On the line. 0 ft
- ten feet off the side line
- Six feet allowed there. 10 ft
- a side or rear street line
- Four feet. 4 ft
- the public right-of-way
- Only by special privilege.

- 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 Milwaukee?
Compare fence height across all 50 states
Milwaukee answers this, but the answer changes depending on the yard, the material and how open the fence is above four feet.
Milwaukee sets four feet as the base in both the front yard and the side yard, which is stricter than most cities on the side, and then sells the extra two feet for openness in three different ways. In a front yard only an ornamental metal fence may reach six feet, and it has to be at least fifty percent open overall even counting its masonry or wood piers. In a side yard six feet is available where the whole fence is chain link, wrought iron or similar open construction, or where the part above four feet is at least half open, with a solid four foot fence topped by two feet of wood lattice given as the worked example. A side yard fence may also reach six feet outright if it stands more than ten feet from the side lot line. A rear yard gets six feet with no conditions, unless it runs along a side or rear street, where four feet returns.
A fence located in a front yard shall not exceed 4 feet in height. However, an ornamental metal fence may be erected to a height of 6 feet. Such ornamental fence may include piers constructed of masonry, wood or other approved materials, provided the fence is at least 50% open overall.
The answer turns on the yard, the material and how open the fence is above four feet.
- a front or side yard
- Four feet. 4 ft
- half open above four feet
- Six feet. 50%
- a rear yard
- Six feet. 6 ft
- a construction site
- Nine feet, removed when the job ends. 9 ft
Also on fence height in Milwaukee
- 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 Milwaukee?
Compare permits across all 50 states
Milwaukee answers this, but the answer changes depending on what the fence is for and where it stands.
The zoning chapter sets no general fence permit and no fee. Two approvals are named and each is tied to one situation. The commissioner of neighborhood services may permit a fence over six feet in specific locations on a premises to stop balls and other objects damaging adjoining buildings, which is a discretionary lift aimed at ball fields rather than at privacy. And a fence or retaining wall may extend into the public right-of-way only as chapter 245 allows or under a special privilege granted by the common council, which puts a fence over the property line in front of the city council rather than a counter clerk. Two more approvals appear indirectly: a fence enclosing a swimming pool has to satisfy the department of neighborhood services rules for pools, and a fence used to meet a required screen may be built to whatever height the screening section demands.
Notwithstanding any other provision of this paragraph, the commissioner of neighborhood services may permit a fence in excess of 6 feet in height in specific locations on a premises to prevent balls and other objects from damaging adjoining buildings or premises.
The answer turns on what the fence is for and where it stands.
- an ordinary fence
- No permit named in the zoning chapter.
- a ball stop over six feet
- The commissioner may allow it.
- a fence over the right-of-way
- A special privilege from the common council.
- a pool fence
- The pool rules apply as well.

- set in state lawWisconsin 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. Wis. Admin.

Pool fence requirements in Milwaukee

Milwaukee 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 Milwaukee
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 Milwaukee 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 Milwaukee
Compare how height is measured across all 50 states
Milwaukee answers this in its own law. The words that do it are quoted below.
Milwaukee answers the sloping boundary question by pointing at the neighboring lot rather than at a grade. Where a retaining wall exists at or adjacent to a property line and the neighboring property sits at a higher grade, the fence height may be measured to a height allowed on that higher property, so the owner on the low side is not punished for the difference in ground. The same paragraph carries a companion rule about the limit rather than the datum: where a taller fence is permitted directly across the property line on the abutting property, a fence on this side may be erected to that same height. Between them, the two sentences make a boundary fence a shared thing rather than two separate ones, which is rare. One thing is expressly outside the measurement: a decorative gate or trellis at an entrance may extend above the permitted fence height to ten feet, provided it is no more than six feet wide.
Where a fence is located along a lot line that abuts another property, and a higher fence is permitted directly across the property line on that property, the fence may be erected to the height permitted on the abutting property. Where a retaining wall exists at or adjacent to a property line and the neighboring property has a higher grade, the fence height may be measured to a height allowed on that higher property.

Also on how height is measured in Milwaukee
- left to the townWisconsin 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. Wis. Stat. 62.23(7)(am)Wisconsin · Zoning code
Fence rules for corner lots in Milwaukee
Compare corner visibility across all 50 states
Milwaukee answers this, but the answer changes depending on the zoning district and whether the object is opaque.
Milwaukee sizes its vision triangle by zoning district and lets it disappear entirely in the densest ones. Twenty five feet applies in the large lot single family, two family, multi-family, residence-office, neighborhood shopping, local business, regional business, industrial-office, light industrial and park districts. Twenty feet applies in the RS5, RT3 and RM3 districts, and fifteen in RS6, RT4, RT5, RM4 and RO2, so the distance shrinks as lots get smaller and houses come closer to the corner. In all other districts, which includes downtown, no vision triangle is required at a street intersection at all. Ten feet applies everywhere in the city where an access drive meets a street. Inside the triangle the test is opacity rather than height alone: an opaque fence, a coniferous tree or shrub, or a utility box may not exceed three feet, while semi-opaque and open fences, deciduous trees and shrubs, sign and utility poles and narrow masonry piers are all permitted.
Opaque fences and other opaque objects, such as coniferous trees and shrubs and utility boxes, located in the vision triangle shall not exceed 3 feet in height. Semi-opaque and open fences and other semi-opaque objects, such as deciduous trees and shrubs, sign and utility poles, traffic standards, and masonry fence piers not exceeding 16 inches in width, shall be permitted.
The answer turns on the zoning district and whether the object is opaque.
- the low density districts
- Twenty five feet. 25 ft
- the densest residential districts
- Fifteen feet. 15 ft
- downtown and the rest
- No triangle at all.
- an opaque fence inside one
- Three feet. 3 ft
Also on corner visibility in Milwaukee
- 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 Milwaukee
Compare retaining walls across all 50 states
Milwaukee 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 Milwaukee
Compare materials across all 50 states
Milwaukee answers this, but the answer changes depending on the material and how open the fence is.
Milwaukee bans three materials in one sentence and names no others. Barbed wire, concertina wire and razor wire fences are prohibited, flatly, with no district exception, no security plan and no agricultural carve-out, which is unusual because most codes that ban wire in houses allow it somewhere. Everything else is regulated by how much can be seen through rather than by what it is made of. Chain link and wrought iron are named as the way a side yard fence earns six feet, and an ornamental metal fence is the only thing that reaches six feet in a front yard. Two rules govern how a fence is put together rather than what it is. The vertical and horizontal supporting members have to face the interior of the lot, so the neighbor gets the finished side. And a masonry fence pier no more than sixteen inches wide is permitted inside a vision triangle where a solid fence is not.
Barbed-wire, concertina-wire and razor-wire fences are prohibited.
The answer turns on the material and how open the fence is.
- barbed, concertina or razor wire
- Prohibited outright.
- chain link or wrought iron
- How a side yard fence earns six feet.
- ornamental metal
- The only six foot front yard fence.
- the posts and rails
- They face the owner, not the neighbor.
Also on materials in Milwaukee
- 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 Milwaukee

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 Milwaukee 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 Milwaukee
- 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 Milwaukee publishes, plus the Wisconsin rules that apply where the city sets none. Fence laws in Wisconsin has the state layer in full.
