Who owns the fence between two properties in Gilroy?

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 Gilroy 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 Gilroy?
Compare fence height across all 50 states
Gilroy answers this, but the answer changes depending on the fence height, and the distance from the curb.
A Gilroy front yard fence over three feet has to stand twenty six feet back from the curb. The distance is measured from the curb rather than from the property line, which is unusual and which puts the fence well behind the sidewalk on a normal lot. An arbor, trellis or pergola can reach eight feet in the front yard on the same twenty six foot setback.
Front Yard Fences and Hedges: Got a fence or hedge in your front yard? If it's over 3 feet high, remember to set it back at least 26 feet from the curb.
The answer turns on the fence height, and the distance from the curb.
- three feet or under
- No setback from the curb applies. 3 ft
- over three feet in a front yard
- Twenty six feet back from the curb. 26 ft
Also on fence height in Gilroy
- 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
Do I need a permit for a fence in Gilroy?

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 Gilroy 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

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.

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 Gilroy 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 Gilroy
Compare how height is measured across all 50 states
Gilroy answers this in its own law. The words that do it are quoted below.
Gilroy allows seven feet in most cases and measures it from the ground on the higher side of the fence. On a slope that is the strict reading: the owner standing on the low side sees a fence taller than seven feet, and the number the city checks is the short one. Hedges are held to the same figure as fences in the same sentence.
General Height Rule: In most cases, your fences and hedges can be up to seven feet tall. This measurement is taken from the ground on the higher side of the fence.

Also on how height is measured in Gilroy
- 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 Gilroy
Compare corner visibility across all 50 states
Gilroy answers this in its own law. The words that do it are quoted below.
On a Gilroy corner lot a fence or hedge over three feet keeps sixteen feet back from the curb, and ten feet back from the street side property line where it is near the driveway side of an alley or a key lot. The city adds a separate triangle rule under code section 20.60 for hedges and shrubs at the corner itself. Sixteen feet is ten feet less than the front yard figure, so a corner lot loses less depth than a mid block one.
Any fence or hedge over 3 feet must be set back 16 feet from the curb. If it's near the driveway side of an alley or a key lot, set it back 10 feet from the street-side property line.

- set in state lawCalifornia 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. Cal. Sts. & Hy.

Gilroy 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.

Gilroy answers this in its own law. The words that do it are quoted below.
Gilroy bars four materials from residential fencing: barbed wire, razor wire, wire mesh and electrified fence. Wire mesh is the one worth noticing. Barbed and razor wire and electric fencing are on most prohibited lists, but plain wire mesh is ordinary garden fencing in many cities and is named here alongside them.

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