Fence laws in Fairfield, California, question by question

The short version

Who pays on the line
Fairfield states two clearances in the same sentence and they are very different sizes: three feet from any fire hydrant, and one foot from a utility or a utility cabinet, and the answer turns on whether the obstruction is a fire hydrant or a utility. The figure is 36 inches, for clearance required around a fire hydrant.
How tall
Fairfield draws its line fifteen feet back from the front property line rather than at the required setback, and the answer turns on how far the fence sits from the front property line. The figure is 42 inches, for fence height within fifteen feet of the front property line.
Permits
California does not write its own building code from scratch.
Pool barriers
A pool fence in California stands at least sixty inches high. The figure is 60 inches, for minimum height of a pool enclosure.
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
Where two Fairfield lots sit at different levels, the fence between them is measured using the finished grade of the higher parcel at the fence location.
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
Fairfield 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
California sets a wire standard for a lawful fence in grazing counties. The figure is 3 strands, for barbed wires in a lawful wire fence. It reaches lawful fences in grazing counties only.
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.

Fairfield answers this, but the answer changes depending on whether the obstruction is a fire hydrant or a utility.

Fairfield states two clearances in the same sentence and they are very different sizes: three feet from any fire hydrant, and one foot from a utility or a utility cabinet. Naming street lights as the example of a utility is the useful part, because a light standard in a parkway is the thing most likely to be in the way of a fence line and the least likely to be thought of as a utility.

Location. No fence, wall, hedge, or other structure shall be installed or maintained within 36 inches of any fire hydrant and no closer than 12 inches to any utility (e.g., street lights) or utility cabinet.

Also on fences on the property line in Fairfield

  • set in state lawTwo 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. Civ. Code 841California · Statute
  • set in state lawThe notice has to say six things: that the law starts from an even split, what is wrong with the fence now, what is planned instead, what it is expected to cost, how the cost gets shared, and when the work happens. Civ. Code 841(b)(1)California · Statute

How tall can a fence be in Fairfield?

Fairfield answers this, but the answer changes depending on how far the fence sits from the front property line.

Fairfield draws its line fifteen feet back from the front property line rather than at the required setback. Inside that band a fence on a single family lot, a duet or a duplex stops at forty two inches. Beyond it the limit is seven feet, which is a foot more than most California cities read for this site allow. The band is a fixed distance, so it does not move with the zoning district.

Single-family residential uses. Fences, walls, or hedges on a property with a single-family home, duet, or duplex shall be limited to a height of 42 inches within 15 feet of the front property line, and to seven feet in height beyond 15 feet from the front property line.

  • no rule, documents checkedCalifornia sets no limit on how tall a fence at a house can be. 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 Fairfield?

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 Fairfield 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 Fairfield

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

A pool fence in California stands at least sixty inches high. 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.

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

An enclosure shall have all of the following characteristics: (a) Any access gates through the enclosure open away from the swimming pool, and are self-closing with a self-latching device placed no lower than 60 inches above the ground. (b) A minimum height of 60 inches. (c) A maximum vertical clearance from the ground to the bottom of the enclosure of two inches. (d) Gaps or voids, if any, do not allow passage of a sphere equal to or greater than four inches in diameter. (e) An outside surface free of protrusions, cavities, or other physical characteristics that would serve as handholds or footholds that could enable a child below the age of five years to climb over.

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 Fairfield 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 Fairfield

Compare how height is measured across all 50 states

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

Where two Fairfield lots sit at different levels, the fence between them is measured using the finished grade of the higher parcel at the fence location. That is the stricter of the two readings and it means the owner on the low side sees more fence than the number suggests while getting no extra allowance for it.

Parcels with grade differential. Where there is a difference in the ground level between two sides of a fence (including property line fences), the height of any fence or wall constructed shall be determined by using the fence location finished grade of the higher parcel.

Also on how height is measured in Fairfield

  • left to the townCalifornia 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. Cal. Gov. Code 65850(c)(1)California · Zoning code

Fence rules for corner lots in Fairfield

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 Fairfield 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.

Fairfield 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.

Fence materials allowed in Fairfield

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

California sets a wire standard for a lawful fence in grazing counties. A wire fence takes three tight barbed wires on solid posts set no more than a rod apart, with one wire at least four feet up. Any fence as strong and as tall as that one counts too.

This one is California law, not Fairfield 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.

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.

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