Fence laws in Alameda, 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
- Every height in Alameda has a taller version for a see-through fence, and the answer turns on which yard the fence stands in, and whether the material is see-through. The figure is 20 feet, for depth of the front yard for the purpose of the fence rules.
- Permits
- A fence over seven feet in Alameda needs a building permit, and certain solid fences such as masonry walls need one whatever their height. The figure is 7 feet, for fence height above which a building permit is required.
- 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
- Alameda leaves the measuring rule to the legislative body of each county and city, through its zoning ordinance.
- Corner lots
- Alameda leaves corner clearance to the City Engineer, deciding the dimensions of the visibility zone case by case.
- Retaining walls
- Alameda 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
- Alameda defines see-through as a measurement rather than a description. The figure is 50 percent, for the share of opaque material a see-through fence must stay under.
- 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 Alameda?

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 Alameda 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 Alameda?
Compare fence height across all 50 states
Alameda answers this, but the answer changes depending on which yard the fence stands in, and whether the material is see-through.
Every height in Alameda has a taller version for a see-through fence. The front yard, which is the area within twenty feet of the front property line, runs three feet solid and four feet see-through, and a Planning Permit can take it to five. A side or rear yard runs six feet solid and eight feet see-through. Inside a visibility zone nothing passes three feet whatever it is made of.
Fences along the front yard may be up to three feet (3') tall, and may be extended up to four feet (4') with see-through fencing material.

- 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 Alameda?
Compare permits across all 50 states
Alameda answers this in its own law. The words that do it are quoted below.
A fence over seven feet in Alameda needs a building permit, and certain solid fences such as masonry walls need one whatever their height. So the seven feet answer only covers wood and similar construction. A two foot masonry garden wall is a permit in Alameda and a six foot wood fence beside it is not, which is the same split Murrieta and Woodland draw. Arbors and decorative fence posts add a Planning Permit on top, to review how they sit against their surroundings.
A Building Permit is required for fences that exceed seven feet (7') in height. Certain types of solid fences, such masonry walls, will require a Building Permit regardless of height.

- 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

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 Alameda law. All California findings

(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 Alameda 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 Alameda
Compare how height is measured across all 50 states
Alameda 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 Alameda 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 Alameda
Compare corner visibility across all 50 states
Alameda does not set this. It leaves it to the City Engineer, deciding the dimensions of the visibility zone case by case.
Alameda states the visibility rule and hands the dimensions to the City Engineer. The three foot limit inside a visibility zone is fixed, but how far the zone reaches is decided case by case on traffic and safety considerations rather than printed anywhere. So the height is knowable from the handout and the area it applies to is not, which makes the corner a question for the Engineer rather than one a drawing can answer.
The “visibility zone” is determined by the City Engineer and the dimensions of this zone are based on traffic and safety considerations.

- 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.

Retaining wall rules in Alameda

Alameda 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 Alameda

Alameda answers this in its own law. The words that do it are quoted below.
Alameda defines see-through as a measurement rather than a description. The opaque part of the fence, not counting the supporting posts, has to be less than fifty percent of the total square footage. Excluding the posts is the part that matters: a picket fence with heavy four by four posts would fail a naive count and passes this one. The handout names pickets, lattice and decorative wrought iron as examples and leaves the list open.
See-through style material refers to any fencing material in which the amount of opaque fence material, excluding its supporting posts, is less than 50% of the total square footage.

- set in state lawCalifornia sets a wire standard for a lawful fence in grazing counties.

- depends, see the pageChain link in Alameda is settled by what the fence faces. It is prohibited in the front yard of any residential property outright. In a rear or side yard it is allowed up to six feet, but only where that yard does not adjoin a public street or a public or quasi-public use such as a park, a school or a community facility. Everywhere else it takes a Use Permit. Barbed wire and razor wire get no such gradient: they are barred from any part of any barrier or fence. Fences, Frequently Asked QuestionsAlameda · Zoning code
Livestock and boundary fence law in Alameda
Compare agricultural fencing across all 50 states
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 Alameda 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.

Section 17124 lets the board of supervisors of any county put the same label on the county or part of it. 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 Alameda publishes, plus the California rules that apply where the city sets none. Fence laws in California has the state layer in full.
