Fence Companyin La Cañada Flintridge, CA
A fence company in La Cañada Flintridge works to a stricter line than the state model: the City amended its building code so only fences up to 42 inches skip a permit, and R-1 front and street-side fences above 42 inches must be at least 80 percent open and no taller than 6 feet. Hillside lots add review.
Fences here mark lines that are often old. The Census Bureau's 2024 five-year estimates count 6,643 of the city's 7,053 housing units as detached houses, about a quarter of all units date from before 1950, and the city itself is younger than its lots: Flintridge and La Cañada merged into one city on December 8, 1976, on land that began as Rancho La Cañada, bought in 1875 by Jacob Lanterman and Adolphus Williams. A fence that has stood since a decades-old subdivision may not sit where the survey says the line runs.
MDG Builders (CSLB #1040337) takes fence jobs as a general contractor: we measure, read the City's zoning and building limits, file the permit when one is needed and schedule the crew, while a licensed C-13 fence subcontractor builds. Pricing sits on our fencing page, the other trades are on the La Cañada Flintridge overview, and the fence guides for Glendale and Pasadena show how the neighboring cities draw their lines.
What La Cañada Flintridge's building code and R-1 zone say about fences
Where fencing permits come from in La Cañada Flintridge: City of La Cañada Flintridge Community Development Department, Building & Safety Division.
- The city amended the county code (Section 7.08.060) so work exempt from a building permit includes fences not used as a barrier to a private pool, spa or hot tub only if they do not exceed 42 inches; ground signs may be up to 6 feet and temporary construction fencing up to 6 feet. The R-1 zone says the same from the zoning side: building permits are required for all fences, gates and walls over 42 inches high.
- All fences and walls over 42 inches high in the R-1 zone need a zoning clearance review: the fence must be compatible with its surroundings and the single-family residential design guidelines, and Planning may require simplified decoration. Finished sides must face the neighbor, trail, open space or public right-of-way, and white or very pale fences are generally discouraged.
- In the front setback and street side yard of an R-1 lot, any fence, gate or wall may be up to 42 inches above adjacent grade; above 42 inches the fence may not exceed 6 feet (posts up to 6 feet 6 inches), gates may reach 8 feet 6 inches, a light on a pillar may not push total height above 7 feet, pedestrian gates are limited to 6 feet wide and vehicle gates to 20 feet, and the portion above 42 inches must be at least 80 percent open (for example wrought iron with bars at least 4 inches apart).
- In R-1 side and rear setbacks, fences, gates and freestanding walls are limited to 6 feet measured from the highest adjacent grade; fences and walls next to trails on the city's Trails Master Plan, designated open space or a non-single-family zone may reach 8 feet measured from the trail or open-space side. On a corner lot, fences forward of the front setback line follow the front setback rules and those behind it are limited to 6 feet.
- R-1 prohibited fence materials are spears or pointed tops, unfinished plywood, corrugated metal, bare metal wire, barbed wire, mesh fences and electrically charged fences; chain link may not be installed where it is prominently visible from the public right-of-way except as a temporary construction fence.
- For any new property line fence or freestanding wall within 5 feet of a property line, Planning notifies the adjoining owners before building permits issue and the applicant must have the line marked in the field and a survey by a licensed land surveyor submitted; the requirement can be waived if the adjoining owners sign written acceptance on the site plan.
- R-1 retaining walls are capped at 5 feet 6 inches for inward-facing walls and 3 feet 6 inches for outward-facing walls in the front setback; in side and rear setbacks an outward-facing wall up to 3 feet 6 inches needs written acceptance from the adjoining owners and one up to 5 feet 6 inches goes through director's review. A retaining wall and fence built closer together than the wall's own height count as one fence for height.
- A driveway gate must leave room to stack at least one vehicle off the street, at least 20 feet from the face of the curb to the nearest point of an open swing-in gate or closed swing-out gate, and no gate may be in the public right-of-way. Landscaping taller than 3 feet 6 inches within 20 feet of the street curb goes to Public Works for a line-of-sight review.
How tall can a fence be in La Cañada Flintridge before it needs a permit?
Forty-two inches is the permit line. The City amended the county code in Section 7.08.060 so that work exempt from a building permit includes fences, other than pool barriers, only if they do not exceed 42 inches, and the R-1 zone says the same from the zoning side: building permits are required for all fences, gates and walls over 42 inches high. Every fence or wall above that height also needs a zoning clearance review, which tests it for fit with its surroundings and the single-family design guidelines, and Planning may ask for simpler decoration.
Behind the front setback the height cap is 6 feet, measured from the highest adjacent grade, in the R-1 side and rear setbacks. A fence or wall beside a trail on the City's Trails Master Plan, designated open space or a non-single-family zone may reach 8 feet, measured from the trail or open-space side. On a corner lot, a fence forward of the front setback line follows the front yard rules and one behind it is limited to 6 feet. Finished sides must face the neighbor, trail, open space or public right-of-way.
Put the height at the highest adjacent grade on the plan, since the City measures from there.
What fence can I build in a front yard or street side yard in La Cañada Flintridge?
An R-1 front setback or street side yard allows any fence, gate or wall up to 42 inches above adjacent grade. Above 42 inches the fence may not exceed 6 feet, with posts up to 6 feet 6 inches and gates up to 8 feet 6 inches, and the part above 42 inches must be at least 80 percent open, for example wrought iron with bars at least 4 inches apart. A light on a pillar may not push the total past 7 feet, pedestrian gates are limited to 6 feet wide and vehicle gates to 20 feet.
Materials are limited too. R-1 prohibits spears or pointed tops, unfinished plywood, corrugated metal, bare metal wire, barbed wire, mesh fences and electrically charged fences, and chain link may not be installed where it is prominently visible from the public right-of-way, except as a temporary construction fence. The City also generally discourages white or very pale fences, so a bright white vinyl panel line is a question for Planning, not a catalog choice. In the Foothill Community District zone, only non-view-obscuring fencing up to 42 inches is allowed in the front setback, and materials and color must match the structures nearby.
Does a new fence near the property line in La Cañada Flintridge need a survey?
Yes, for any new property line fence or freestanding wall within 5 feet of the line. Planning notifies the adjoining owners before building permits issue, and the applicant must have the line marked in the field and submit a survey by a licensed land surveyor. The requirement can be waived if the adjoining owners sign written acceptance on the site plan. The City's own ADU page warns that legal property lines often differ from existing fences, which is the reason the survey exists.
Cost sharing is a separate matter and comes from state law, not from the City. Under California Civil Code section 841, adjoining owners are presumed to share the reasonable cost of building, maintaining or replacing a boundary fence equally unless they agree otherwise in writing, and the owner planning the work must give each affected neighbor 30 days' written notice with the problem, the proposed fix, the estimated cost, a cost-sharing proposal and a timeline. The City's written acceptance and the cost agreement both need the same neighbor's signature, so ask for the two together.
Can I build a fence on a hillside lot in La Cañada Flintridge?
Yes, but the slope changes who reviews it. The city runs from about 970 feet near Devil's Gate Dam to about 2,400 feet in its highest neighborhood, and a lot with an average slope of 15 percent or more needs a hillside development permit for any project that requires a building permit. On those lots fences and freestanding walls must be placed away from any ridgeline or slope crest so they are not visible against the sky from off site.
Protected trees are the other hillside surprise. Native oaks and California sycamores of 12 inches or more across, on R-1 lots, are protected, and the tree ordinance treats building within 30 feet of one as development activity that brings a site plan and an arborist report. Whether a row of fence footings counts is a question for Planning before a post is set. Hillside status depends on the parcel's slope, so confirm it with Planning at (818) 790-8881.
Can a fence sit on a retaining wall in La Cañada Flintridge?
Only if the two heights are counted together. A retaining wall and a fence built closer to each other than the wall's own height count as one fence for height purposes, so a 3 foot wall under a 6 foot fence is a 9 foot structure in the City's eyes. R-1 retaining walls in the front setback are capped at 5 feet 6 inches when they face inward and 3 feet 6 inches when they face outward. In side and rear setbacks, an outward-facing wall up to 3 feet 6 inches needs written acceptance from the adjoining owners, and one up to 5 feet 6 inches goes through director's review.
On hillside lots, any retaining wall over 3 feet must be screened by a building or landscaping, and approval rises with height: director's review at 3 feet or lower, an administrative hearing from 3 to 6 feet and a planning commission hearing above 6 feet for conventional walls. Block and stone are masonry, so a C-13 fence contractor does not build them; the CSLB definition of C-13 excludes masonry walls, and we hire a masonry specialist for that part.
What are the rules for driveway gates and pool fences in La Cañada Flintridge?
A driveway gate must leave room to stack at least one vehicle off the street, at least 20 feet from the face of the curb to the nearest point of an open swing-in gate or a closed swing-out gate, and no gate may stand in the public right-of-way. Landscaping taller than 3 feet 6 inches within 20 feet of the street curb goes to Public Works for a line-of-sight review, so a hedge beside the new gate can be flagged.
A fence that serves as a pool barrier loses the 42 inch exemption. The Los Angeles County pool enclosure manual hosted by the City, number 118 and dated August 16, 2018, calls for a barrier at least 60 inches high, no more than 2 inches of clearance below it, gaps that stop a 4 inch sphere, and self-closing, self-latching gates that open away from the pool with the release at least 60 inches from the bottom of the gate. Double doors, doors wider than 4 feet and driveway gates may not be part of the barrier. The manual rests on the 2017 county code, so confirm the current version. An R-1 pool or spa must also sit 5 feet from side and rear lines.
How much does fence installation cost in La Cañada Flintridge, and who should I hire?
We found no La Cañada Flintridge fence survey, so these are Los Angeles planning ranges drawn from Angi, HomeGuide, Thumbtack and Fixr: $25 to $55 per linear foot for a 6 foot wood or vinyl privacy fence, $12 to $30 for chain link and $35 to $85 for aluminum or ornamental iron, which puts a typical 100 foot backyard run at about $2,500 to $5,500. Angi's Los Angeles page, updated August 4, 2026, lists a $3,051 average job, and federal wage data for May 2025 puts fence erectors in the Los Angeles area at a mean $28.00 an hour. Block walls, horizontal slats, gates with openers and steep lots have no independent price, so the written proposal sets them.
A fence over 42 inches needs a permit here, so it needs a licensed contractor even under $1,000, because the state's minor-work limit excludes permitted work. Business and Professions Code sections 7159 and 7159.5 cap a down payment at $1,000 or 10 percent, whichever is less. On an MDG job you can ask for the subcontractor's license number and proof of insurance, and our license-check guide shows what the CSLB record contains.

Other work we manage in La Cañada Flintridge
La Cañada Flintridge fence questions, answered
Do I need a permit to build a fence in La Cañada Flintridge?
Yes, once the fence is taller than 42 inches or serves as a pool barrier. Section 7.08.060 exempts only fences up to 42 inches, and the R-1 zone requires building permits for all fences, gates and walls above that height. Applications go through the ConnectLCF portal, and fences over 42 inches also need a zoning clearance.
How tall can my front fence be in California?
In La Cañada Flintridge's R-1 front setback or street side yard, up to 42 inches. Above that the fence may reach 6 feet only if the part above 42 inches is at least 80 percent open, for example wrought iron with bars at least 4 inches apart. Other cities set other limits, so the answer changes at the city line.
Can I put up a 7ft fence?
Not in an R-1 side or rear setback here, where the cap is 6 feet measured from the highest adjacent grade. Next to a trail on the Trails Master Plan, designated open space or a non-single-family zone, a fence may reach 8 feet measured from the trail or open-space side. Over 42 inches it also needs a permit.
What happens if I don't have a permit for a fence?
The City can stop the job and charge more. Its Building and Safety FAQ says starting work before a permit is issued can bring doubled permit fees, administrative citations and possible prosecution, and the City will not issue a new permit for a property with an active code case unless the permit resolves it. Ask before the posts go in.
Does your neighbor have to pay for half the fence in California?
Usually yes, if the fence is a shared boundary fence. California Civil Code section 841 presumes adjoining owners share the reasonable cost of building, maintaining or replacing it equally unless they agree otherwise in writing, and the owner planning the work must give each neighbor 30 days' written notice. The presumption can be argued.
How much should a 100 ft fence cost?
For a 6 foot wood or vinyl privacy fence, our Los Angeles planning range is about $2,500 to $5,500, which is $25 to $55 a linear foot. Angi's Los Angeles page lists $2,100 to $2,350 for 100 feet. The sources disagree at the low end, and we found no La Cañada Flintridge survey, so a measured proposal sets the price.
Is it cheaper to install a wood or vinyl fence?
Angi's Los Angeles page shows wood at $1,600 to $2,500 and vinyl at $1,850 to $3,400 for its sample job, so wood runs lower. Other sources overlap, and fence installation here also depends on color: the City generally discourages white or very pale fences, which affects many vinyl lines. Ask Planning about the color first.
Can I put a privacy fence up in my front yard?
Not a solid one. In an R-1 front setback or street side yard the fence may rise to 42 inches, and anything above that, up to 6 feet, must be at least 80 percent open. In the Foothill Community District zone only non-view-obscuring fencing up to 42 inches is allowed in the front setback.
Can you install fences on hillsides or steep slopes?
Yes, with extra review. A lot with an average slope of 15 percent or more needs a hillside development permit for any project requiring a building permit, and fences must stay away from ridgelines and slope crests so they are not visible against the sky from off site. Confirm your parcel's slope with Planning.
What is the maximum height of a retaining wall without a permit in California?
We could not confirm an exemption for La Cañada Flintridge, because the County list of permit-exempt work was not readable. The City does cap R-1 front-setback retaining walls at 5 feet 6 inches facing inward and 3 feet 6 inches facing outward, and it adds a retaining wall's height to a nearby fence. Ask Building and Safety.
