Fence laws in Cupertino, California
What the Cupertino municipal code says about fences, one topic at a time, with the section number and a link to the document behind every line. Where Cupertino sets no rule of its own, the California rule is shown in its place and marked as such.
Fence laws in Cupertino, California, question by question
The short version
- Who pays on the line
- Cupertino prints exactly what the eighth foot costs, and the answer turns on whether the fence passes seven feet. The figure is 7 feet, for height below which nothing is required.
- How tall
- In the R1, R2 and R3 zones, Cupertino allows a fence up to eight feet standing on the property line itself, everywhere except the front property line, and the answer turns on which boundary the fence stands on. The figure is 8 feet, for fence height allowed on a side or rear property line.
- Permits
- A driveway or roadway gate in Cupertino stands thirty feet back from the front or street side property line, which is far enough that a car clears the sidewalk and most of the parking strip before the gate opens. The figure is 30 feet, for setback of a driveway or roadway gate from the front or street side line. It reaches driveway and roadway gates only.
- 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
- Cupertino 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
- Cupertino 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
- Cupertino leaves fence materials to Cupertino Municipal Code 19.48.030(F). It reaches the Residential Hillside and Open Space zones 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.

Cupertino answers this, but the answer changes depending on whether the fence passes seven feet.
Cupertino prints exactly what the eighth foot costs. Up to seven feet: no neighbor approval, no building permit. Up to eight feet: both, and the approval is a Fence Approval Form submitted with the building permit application rather than a conversation. The neighbor therefore holds a documented veto over the last foot, and the city collects the evidence of consent before it issues anything.
Fence Height Neighbor Approval Building Permit Up to 7 feet Not required Not required Up to 8 feet Required (submit form with building permit application) Required
The answer turns on whether the fence passes seven feet.
- up to seven feet
- Neither neighbor approval nor a building permit. 7 ft
- up to eight feet
- Neighbor approval on the city form, filed with a building permit application. 8 ft
Also on fences on the property line in Cupertino
- 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 Cupertino?
Compare fence height across all 50 states
Cupertino answers this, but the answer changes depending on which boundary the fence stands on.
In the R1, R2 and R3 zones, Cupertino allows a fence up to eight feet standing on the property line itself, everywhere except the front property line. In the front yard setback the limit is three feet. Eight feet on a boundary is as tall as any residential figure on this site, and it is allowed on the line rather than set back from it, which is the opposite of how most cities handle their tallest fences.
For property zoned R1, R2 or R3, a fence up to eight (8) foot tall may be constructed at the property line except on the front property line.
The answer turns on which boundary the fence stands on.
- on a side or rear property line in R1, R2 or R3
- Up to eight feet, on the line. 8 ft
- in the front yard setback area
- Three feet. 3 ft
Also on fence height in Cupertino
- 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. Code 841California · Statute

Cupertino answers this in its own law. The words that do it are quoted below.
A driveway or roadway gate in Cupertino stands thirty feet back from the front or street side property line, which is far enough that a car clears the sidewalk and most of the parking strip before the gate opens. Going closer, or building a fence outside the ordinance in any other way, is a fence exception decided at a public hearing on published findings, so it is a decision the city makes in the open rather than a fee it charges.
These gates need to be set back thirty feet (30') from the front and/or street side property lines.

- set in state lawCalifornia 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. Health & Saf. Code 17922California · Statute
- 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 Cupertino

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 Cupertino 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 Cupertino 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 Cupertino
Compare how height is measured across all 50 states
Cupertino 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 Cupertino law. All California findings
Regulate all of the following: (1) The location, height, bulk, number of stories, and size of buildings and structures.
The code hands this to the legislative body of each county and city, through its zoning ordinance, which is not published in the code itself.
Fence rules for corner lots in Cupertino

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 Cupertino 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 Cupertino

Cupertino 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 Cupertino 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 Cupertino

Cupertino does not set this. It leaves it to Cupertino Municipal Code 19.48.030(F).
In the Residential Hillside and Open Space zones, Cupertino applies a different set of fence rules so that wildlife can reach their habitat and their paths of travel, and sends the reader to Municipal Code 19.48.030(F) for the detail. No other city read for this site regulates a residential fence for the benefit of animals moving across it. A gate controlling access on a private road or driveway in the hillside zone is allowed with the Director of Community Development approving its design.
Fence regulations are different to allow wildlife access to their habitat and paths of travel. Please check Section 19.48.030(F).
The code hands this to Cupertino Municipal Code 19.48.030(F), which is not published in the code itself.

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 Cupertino 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.

Where the label applies, the land has to be fully fenced before the person on it may take in a stray animal or hold it for payment. Cal. Food & Agric. Code 17122California · 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 Cupertino publishes, plus the California rules that apply where the city sets none. Fence laws in California has the state layer in full.
