What the Westminster municipal code says about fences, one topic at a time, with the section number and a link to the document behind every line. Where Westminster sets no rule of its own, the California rule is shown in its place and marked as such.

Fence laws in Westminster, California, question by question

The short version

Who pays on the line
Two neighbors split the cost of a fence on the line in California.
How tall
Westminster caps a fence or wall at six feet, and at three feet in a front yard, and the answer turns on whether the fence is in a front yard, and whether a variance has been approved. The figure is 3 feet, for fence or wall height in a front yard.
Permits
California does not write its own building code from scratch.
Pool barriers
Westminster requires a pool or spa to be fenced and secured with approved materials, and gives no height figure of its own on this page.
Spite fences
A fence over ten feet tall in California is a private nuisance when it was put up or kept there to annoy the neighbor and the extra height serves no purpose. The figure is 10 feet, for spite fence threshold, with malice required.
Measured from what
Westminster leaves the measuring rule to the legislative body of each county and city, through its zoning ordinance.
Corner lots
California writes no clear view triangle into state law. It reaches the right of way of a state highway, whether or not the whole width is paved only.
Retaining walls
Westminster leaves retaining walls to Title 24 of the California Code of Regulations, the California Building Standards Code, which tracks the International Building Code and the International Residential Code.
Materials
Westminster spells out what its fence section reaches, and the list runs well past fences.
Livestock
California calls a fence lawful when it is strong enough to keep livestock from getting in or out. The figure is 4 feet, for height of the top wire on a lawful wire fence.

Who owns the fence between two properties in Westminster?

California answers this in its own law. The words that do it are quoted below.

Two neighbors split the cost of a fence on the line in California. The law starts from the idea that both get the same benefit from it, so both owe the same share of building it, keeping it up and replacing it. A neighbor about to spend that money gives the other one thirty days written notice first. Either neighbor can show the even split is wrong, and a court can then order less than half or nothing at all.

This one is California law, not Westminster law. All California findings

Adjoining landowners are presumed to share an equal benefit from any fence dividing their properties and, unless otherwise agreed to by the parties in a written agreement, shall be presumed to be equally responsible for the reasonable costs of construction, maintenance, or necessary replacement of the fence.

How tall can a fence be in Westminster?

Compare fence height across all 50 states

Westminster answers this, but the answer changes depending on whether the fence is in a front yard, and whether a variance has been approved.

Westminster caps a fence or wall at six feet, and at three feet in a front yard. Anything taller needs a variance approved before construction, which is a heavier route than the administrative permit several nearby cities use for the same thing. The city frames the rule as a traffic visibility and public safety matter rather than as a design one.

Walls, fences, and hedges which present a potential traffic visibility problem or public safety hazard are regulated by the City’s Municipal Code based on height and location. Walls and fences have a maximum height limit of six feet, except in front yards, where the height limit is three feet. A variance must be approved by the City prior to construction of overheight fences.

Cities and counties write that in their zoning codes and the answer changes a lot from one town to the next. The one height in state law is the ten feet in the spite fence rule, and that only matters when the fence was put up to annoy a neighbor. It is not a building limit. Civ.

Do I need a permit for a fence in Westminster?

California answers this in its own law. The words that do it are quoted below.

California does not write its own building code from scratch. Section 17922 adopts Title 24 of the California Code of Regulations and requires it to ask for much the same things as the International Building Code and the International Residential Code, with state additions and cuts. So the permit rule for a fence starts out as outside code text that California then edits.

This one is California law, not Westminster law. All California findings

The building standards and rules and regulations shall impose substantially the same requirements as are contained in the most recent editions of the following international or uniform industry codes as adopted by the organizations specified:

  • set in state lawA California city or county can make the statewide building code stricter, but not quietly. Section 17958.7 makes the city council say in writing why each change is needed because of local weather, ground or land shape. That finding goes to the California Building Standards Commission, and the change does nothing until it is filed. The finding is a public record, which is why a local permit line can sit well below the statewide one. Health & Saf. Code 17958.7California · Statute

Pool fence requirements in Westminster

Compare pool barriers across all 50 states

Westminster answers this in its own law. The words that do it are quoted below.

Westminster requires a pool or spa to be fenced and secured with approved materials, and gives no height figure of its own on this page. The maintenance duty is written into the same sentence as the barrier duty, so a pool left dirty is a code matter in the same way an unfenced one is. A building permit is required to build the pool in the first place.

Permits from the City Building Division are required for the construction of a swimming pool or spa. Pools and spas must be fenced and secured with approved materials, and must be maintained in a clean, safe and sanitary condition.

No more than two inches may be left between the ground and the bottom of it, and no gap in it may pass a four inch ball. The outside face has no handholds or footholds a child under five could climb. Gates open away from the pool and close and latch by themselves, with the latch set no lower than sixty inches above the ground. Health & Saf. Code 115923California · Statute

Spite fence laws in Westminster

Compare spite fences across all 50 states

California answers this in its own law. The words that do it are quoted below.

A fence over ten feet tall in California is a private nuisance when it was put up or kept there to annoy the neighbor and the extra height serves no purpose. Height on its own is not enough. The case turns on proving why the fence is there. The rule covers anything built like a fence, not only a fence.

This one is California law, not Westminster law. All California findings

Any fence or other structure in the nature of a fence unnecessarily exceeding 10 feet in height maliciously erected or maintained for the purpose of annoying the owner or occupant of adjoining property is a private nuisance.

How fence height is measured in Westminster

Compare how height is measured across all 50 states

Westminster does not set this. It leaves it to the legislative body of each county and city, through its zoning ordinance.

California gives a fence height and never says what it is measured from. Civil Code section 841.4 makes a fence over ten feet a private nuisance when it is kept up to annoy a neighbor. It does not say whether the ten feet starts at bare dirt, at the finished yard, or at the high side of a slope. Government Code section 65850 is why the state stops there: it lets any county or city set the place, height and size of structures. So the number and the surface it starts from are both written into local zoning.

This one is California law, not Westminster law. All California findings

Regulate all of the following: (1) The location, height, bulk, number of stories, and size of buildings and structures.

Fence rules for corner lots in Westminster

Compare corner visibility across all 50 states

California answers this in its own law. The words that do it are quoted below.

California writes no clear view triangle into state law. The Streets and Highways Code counts a fence as an encroachment once it stands in, under or over any part of a state highway right of way. Section 670 then makes putting one there without a written permit from the department a misdemeanor. That covers the public strip, not the corner of a private yard. Government Code section 65850 gives every city and county the power to set the height and place of structures, and that is where a corner triangle gets written in California.

This one is California law, not Westminster law. All California findings

“Encroachment” includes any tower, pole, pole line, pipe, pipe line, fence, billboard, stand or building, or any structure, object of any kind or character not particularly mentioned in this section, or special event, which is in, under, or over any portion of the highway.

Retaining wall rules in Westminster

Compare retaining walls across all 50 states

Westminster does not set this. It leaves it to Title 24 of the California Code of Regulations, the California Building Standards Code, which tracks the International Building Code and the International Residential Code.

California has no rule of its own in statute for a wall that holds back earth. The rule is in Title 24 of the California Code of Regulations, which section 17922 adopts by reference and requires to match the newest editions of a named list of outside codes, the International Building Code and the International Residential Code among them. The same section leaves setbacks, side yards, rear yards and property line rules entirely to cities and counties.

This one is California law, not Westminster law. All California findings

The building standards and rules and regulations shall impose substantially the same requirements as are contained in the most recent editions of the following international or uniform industry codes as adopted by the organizations specified:

Fence materials allowed in Westminster

Compare materials across all 50 states

Westminster answers this in its own law. The words that do it are quoted below.

Westminster spells out what its fence section reaches, and the list runs well past fences. A wall used as a fence, a latticework screen, a hedge, a thick growth of shrubs or trees, and an open mesh wire fence are all named. Planting a row of shrubs across a front yard therefore runs into the same three foot limit as building a fence there, with nothing to permit and nothing to inspect.

Fences, walls used as fences, latticework screens, hedges, thick growths of shrubs or trees, open-mesh wire fences, and walls shall be installed and maintained in compliance with the provisions outlined in this Section .

Livestock and boundary fence law in Westminster

California answers this in its own law. The words that do it are quoted below.

California calls a fence lawful when it is strong enough to keep livestock from getting in or out. A wire fence gets real numbers: three tight barbed wires on posts set no more than one rod apart, with one of those wires at least four feet off the ground. Any other fence as tall, as strong and as good at holding animals counts too, and so does a cattle guard wide and deep enough to turn them.

This one is California law, not Westminster law. All California findings

No wire fence is a good and substantial fence within the meaning of this article unless it has three tightly stretched barbed wires securely fastened to posts of reasonable strength, firmly set in the ground not more than one rod apart, one of which wires shall be at least four feet above the surface of the ground.

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