Fence laws in Normal, Illinois, question by question
The short version
- Who pays on the line
- A fence in Normal may sit on the property line, with one exception stated in the same sentence: where the line runs beside a sidewalk the fence comes back at least twelve inches. The figure is 12 inches, for clearance required where a fence runs beside a sidewalk.
- How tall
- Normal prints a table of permitted obstructions and gives fences three rows, one for each height, and the answer turns on the district, the yard, and what the lot next door presents. The figure is 4 feet, for fence allowed in every yard and district.
- Permits
- Illinois has no one statewide permit rule for work at a house.
- Pool barriers
- Normal sets no statewide pool barrier rule. The chapters that were read are listed below. Cities and counties decide this one.
- Spite fences
- Normal has no spite fence statute. The chapters that were read are listed below. Cities and counties decide this one.
- Measured from what
- Normal measures from the established grade to the highest point of the fence, and then names the thing most codes leave ambiguous: any barbed wire or similar material mounted on the fence counts toward the height.
- Corner lots
- Normal leaves corner clearance to the Illinois Department of Transportation, which defines the visibility triangle.
- Retaining walls
- Normal leaves retaining walls to the municipal or county residential building code, or the International Residential Code named in the construction contract. It reaches newly built homes only.
- Materials
- Normal names a material in only two places and both are about what the public sees, and the answer turns on what the fence encloses.
- Livestock

Normal answers this in its own law. The words that do it are quoted below.
A fence in Normal may sit on the property line, with one exception stated in the same sentence: where the line runs beside a sidewalk the fence comes back at least twelve inches. So the boundary fence is the normal case and the only mandatory gap in the town is the one that keeps a fence off the walk. The fence provisions set no requirement about which side faces out, no gate requirement, no rule about two parallel fences on a shared boundary and no maintenance strip, and the other half of the location rule is about sight lines rather than about the neighbor: a fence may not create a visibility conflict at driveways or intersections.
Can be on property line except when adjacent to a sidewalk, in which case must be at least 12 inches off.

- set in state lawIllinois makes both neighbors pay for a fence on the line between them, each one a fair share. Most of the section is about hedge fences. A hedge has to be cut back to four feet in the year after it turns seven, then trimmed to five feet at least every two years. An owner who has done the trimming can give the neighbor ten days written notice, do the work, and sue for the cost. Town officers called fence viewers settle the fights. 765 ILCS 130/3Illinois · Statute
How tall can a fence be in Normal?
Compare fence height across all 50 states
Normal answers this, but the answer changes depending on the district, the yard, and what the lot next door presents.
Normal prints a table of permitted obstructions and gives fences three rows, one for each height. A four foot fence is allowed in all yards in every zoning district, so there is no district where the front of a lot is closed to fencing. A six foot fence is allowed in the side and rear yards of the agricultural district and in the side, rear and corner side yards of the residential, commercial and manufacturing districts. An eight foot fence is allowed in side and rear yards on agricultural, special, commercial and business land, and in all yards in the M-1 and M-2 manufacturing districts. Two adjacency rules cut those back. In R-1, R-2 and R-3 a corner side yard fence may reach six feet unless it faces the front yard of another R zoned property, where that stretch drops to four. A business or manufacturing property directly adjacent to an R district is held to six feet, and to four where the adjacency is to an R front yard.
Properties in R-1, R-2 or R-3 may have a maximum 6-foot fence in the corner side yard unless adjacent to the front yard of another property zoned R, in which case the portion of the fence adjacent to the front yard may be no taller than 4 feet.
15.4-5(C), Fences, and Table 15.4-5(C)
The answer turns on the district, the yard, and what the lot next door presents.
- any yard in any district
- Four feet. 4 ft
- a residential side, rear or corner side yard
- Six feet. 6 ft
- a fence facing the front yard of another R zoned lot
- Four feet along that stretch. 4 ft
- a gas, electric or telephone utility site
- Eight feet in all yards, or six where it adjoins residential land. 8 ft
Also on fence height in Normal
- no rule, documents checkedIllinois sets no limit on how tall a fence at a house can be. The Fence Act names four and a half feet, but that is a floor for a farm fence that holds animals, and the same section lets a town meeting or the county board pick a different number. The state housing law sets no height either. A yard fence height comes from city zoning. 765 ILCS 130/2Illinois · Statute
Do I need a permit for a fence in Normal?
Compare permits across all 50 states
Illinois answers this in its own law. The words that do it are quoted below.
Illinois has no one statewide permit rule for work at a house. Where a town or county has no building code of its own, the Residential Building Code Act makes the builder and the buyer name a code in the building contract, and the International Residential Code applies when they name none. A separate law, in force since January 1, 2025, also requires a city or county code to be at least as strict as a recent model code on how a building is built to hold weight.
This one is Illinois law, not Normal law. All Illinois findings
A contract to build new residential construction in any non-building code jurisdiction must adopt as part of the construction contract the applicability of a residential building code that is agreed to by the home builder and the home purchaser as provided in this Section.
Illinois Residential Building Code Act, Sec. 15
Also on permits in Normal
- no rule, documents checkedThe fence provisions in the Normal zoning code set location, height, measurement and the finish required on a utility site fence, and never mention a permit. No section of the fence entry names an issuing department, an application, a drawing, a survey, a fee, a height threshold or an exemption, and the table of permitted obstructions lists fences at four, six and eight feet without attaching any approval to them. So whatever process applies to putting a fence up in Normal is set outside the zoning chapter that sets the standards for it. 15.4-5(C), Fences, and Table 15.4-5(C)Normal · Zoning code
Pool fence requirements in Normal

Normal law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.
Illinois writes no fence rule for a pool at a private home. The Swimming Pool Safety Act covers pools built for public swimming, and it says plainly that a pool at a private home used by the owner and guests is left out. The state Swimming Facility Code leaves the same pools out. What a home pool needs comes from the city or county and from whatever building code that place has adopted.

Normal law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.
Illinois has no spite fence law. The Fence Act covers who pays, what counts as a legal fence, and how hedges get trimmed. Nothing in it turns on why a fence was built. A fence put up to annoy a neighbor is fought in Illinois as a nuisance case in court, or under a city rule.

How fence height is measured in Normal
Compare how height is measured across all 50 states
Normal answers this in its own law. The words that do it are quoted below.
Normal measures from the established grade to the highest point of the fence, and then names the thing most codes leave ambiguous: any barbed wire or similar material mounted on the fence counts toward the height. That matters here because the town allows barbed wire on a utility site fence, so the eight feet permitted there is eight feet including the wire rather than eight feet of fence with wire above it. The rule sets no allowance for a post or a cap to exceed the limit, does not average grade between two lots and does not address a fence built on a retaining wall.
Fence height is measured from the established grade to the highest point of the fence, including any barbed wire or similar material mounted on the fence.
Also on how height is measured in Normal
- left to the townIllinois never says where a fence height is measured from. The Illinois Municipal Code lets a city set the height and size of buildings, in one short line, and stops there. The Fence Act calls four and a half feet a legal fence and says nothing about the surface those feet start at. So the number and the way to measure it both come from the city. 65 ILCS 5/11-13-1Illinois · Zoning code
Fence rules for corner lots in Normal
Compare corner visibility across all 50 states
Normal does not set this. It leaves it to the Illinois Department of Transportation, which defines the visibility triangle.
Normal states the corner rule in absolute terms and then hands the shape of it to another government. On a corner lot in every district except B-2, General Business, nothing at all may be erected, placed, planted or allowed to grow in the visibility triangle, and the triangle is the one defined by the Illinois Department of Transportation rather than one the town draws. So the code prints no leg length, no height band and no measuring point, and the answer for any particular corner comes from an IDOT standard that is not reproduced in the code. The carve out for B-2 means an entire zoning district has no corner visibility requirement at all. The fence provisions repeat the duty separately, saying a fence may not create a visibility conflict at driveways or intersections.
On corner lots in all districts, except the B-2, General Business District, nothing shall be erected, placed, planted, or allowed to grow in the visibility triangle as defined by the Illinois Department of Transportation.
15.4-5(A), with the fence rule at 15.4-5(C)
The code hands this to the Illinois Department of Transportation, which defines the visibility triangle, which is not published in the code itself.

- set in state lawIllinois treats this as blocking the road. Under the Illinois Highway Code it is a petty offense to block a public highway, and running a fence onto one counts, unless the highway authority in charge gave permission. The fine runs from fifty to five hundred dollars, and more for each day the blockage stays after an order to take it out. That rule covers the road strip. A clear view triangle on private ground comes from city zoning. 605 ILCS 5/9-117Illinois · Traffic code
Retaining wall rules in Normal
Compare retaining walls across all 50 states
Normal does not set this. It leaves it to the municipal or county residential building code, or the International Residential Code named in the construction contract.
Illinois has no statewide building code for homes, so no state law sets a height at which a wall that holds back dirt needs a permit. Where a town or county has its own building code, that code answers it. Where there is none, the Residential Building Code Act makes the builder and the buyer name a code in the building contract, and the current International Residential Code becomes part of that contract when they name none.
This one is Illinois law, not Normal law. All Illinois findings
The home builder and the home purchaser may agree to adopt the International Residential Code or any municipal residential building code or county residential building code that is in effect on the first day of construction in any county or municipality that is within 100 miles of the location of the new home.
The code hands this to the municipal or county residential building code, or the International Residential Code named in the construction contract, which is not published in the code itself.
Fence materials allowed in Normal
Compare materials across all 50 states
Normal answers this, but the answer changes depending on what the fence encloses.
Normal names a material in only two places and both are about what the public sees. A fence at a gas regulator station, gas well head, electric power station or substation, telephone switching station or similar utility use has to be black vinyl coated chain link or other decorative fencing material, and may be topped with barbed wire. A dumpster or recycling enclosure has to be screened on all sides with an opaque fence or masonry enclosure except where garbage pick up needs the opening, and that fence may not be chain link. Outside those two cases the fence provisions name no permitted material, set no opacity requirement and prohibit nothing, so an ordinary residential fence is unrestricted in what it is made of.
Such fences must be black vinyl coated chain link or other decorative fencing material and may be topped with barbed wire.
15.4-5(C), Fences, and Refuse and Recycling Storage Areas
The answer turns on what the fence encloses.
- a utility station fence
- Black vinyl coated chain link or other decorative material, barbed wire allowed on top.
- a dumpster or recycling enclosure
- Opaque fence or masonry, and never chain link.
- an ordinary residential fence
- The fence provisions name no material either way.

Livestock and boundary fence law in Normal
Compare agricultural fencing across all 50 states
Illinois answers this in its own law. The words that do it are quoted below.
Illinois calls a fence legal at four and a half feet tall and in good repair. It can be rails, boards, stone, hedge, barbed wire, woven wire, or anything the town fence viewers judge just as good at keeping cattle, horses, sheep and hogs off the land next door. Voters at the yearly town meeting can set a different number for their own town. In a county with no townships, the county board sets it.
This one is Illinois law, not Normal law. All Illinois findings
Fences four and one-half feet high, and in good repair, consisting of rails, timber boards, stone, hedges, barb wire, woven wire or whatever the fence viewers of the town or precinct where the same shall lie shall consider equivalent thereto suitable and sufficient to prevent cattle, horses, sheep, hogs and other stock from getting on the adjoining lands of another

- set in state lawIllinois puts the duty on the animal owner, not on the neighbor. A separate act bans letting livestock roam loose anywhere in the state and tells owners to put up whatever it takes to hold them. The owner pays in court for the damage loose animals do. The one way out is showing the animals got out without the owner knowing, and that the owner had taken reasonable care to keep them in. 510 ILCS 55/1Illinois · Statute

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 Normal publishes, plus the Illinois rules that apply where the city sets none. Fence laws in Illinois has the state layer in full.
