Fence Companyin Aliso Viejo, CA
A fence company in Aliso Viejo works to the City's limits: 42 inches inside front yard setbacks and 6 feet in side and rear yards, measured from finish grade. Masonry fences under 72 inches need no permit, any pool barrier does, and form PS-240 asks for association approval of fences and walls.
Aliso Viejo's fence lines were drawn by a master plan. The Mission Viejo Company bought the last 6,600 acres of the old Moulton Ranch in 1976, Orange County approved the plan in 1979, and the first homes were offered for sale in March 1982. The Aliso Viejo Community Association, which the City calls the first community-wide property owners' association of its kind in the state, maintains most slopes, medians and parks, so a rear fence often runs beside land you do not own. The Census Bureau's ACS 2024 five-year estimates count 20,507 housing units, 36.4 percent detached houses and 24.5 percent attached, with 43.3 percent of occupied units rented.
On a fencing project, MDG Builders (CSLB #1040337) measures, takes the height and HOA questions to the right counter and schedules the work, while a licensed C-13 fencing subcontractor, or a masonry subcontractor for block walls, builds it. Our fencing page holds the sourced per-foot prices, the Aliso Viejo overview lists our other trades here, and the guides for Laguna Niguel, Mission Viejo and Lake Forest show how neighboring cities set heights.
What Aliso Viejo's fence handout, archived code and pool rules say about fences
Where fencing permits come from in Aliso Viejo: City of Aliso Viejo Community Development Department, Building & Safety Division.
- The City's Fences and Walls handout says construction of masonry fences under 72 inches does not require a permit (its wood fence detail also shows 72 inches as the maximum with no permit) and that retaining walls not over 48 inches measured from the bottom of the footing, with no surcharge or top or toe of slope, need no building permit. A permit is required for any fence that forms part of a pool enclosure, and every fence must still meet the California Building and Residential Codes.
- The City's handout limits fences to 6 feet in side and rear yards and 42 inches within front yard setbacks, measured from finish grade at the base; fences less than 30 inches apart count as one structure. Where a permit is needed it is filed on the portal under 'Residential - Miscellaneous Structures' with a site plan showing property lines, setbacks and total height, elevations, structural details and footing information.
- The City's masonry fence details require footing concrete of at least 4,500 psi with Type V cement and a 0.45 water-cement ratio, footings extending at least 24 inches into undisturbed natural soil compacted to 90 percent, expansion joints every 25 feet, and note that a building permit may be required next to slopes and that a licensed engineer's soils report may be required.
- A copy of Aliso Viejo's municipal code Chapter 15.14 (archived February 7, 2025) says fences higher than the limits, up to 10 feet, need an exception permit from the director, and fences over 10 feet go to the City Council as a site development permit with a public hearing. It also limits fences to 30 inches inside the street-corner sight triangle.
- That archived Chapter 15.14 prohibits barbed wire, razor wire and electrified fencing (except where required by law) and bans chain link in residential districts in any front yard or any area visible from a public street. Retaining walls up to 6 feet are permitted, and a retaining wall over 30 inches high that is visible off site must be landscaped with automatically irrigated shrubs or vines.
- Exhibit A of the City's code ordinance requires a residential pool barrier at least 60 inches high with no more than 2 inches of clearance at the bottom and openings that stop a 4 inch sphere, with self-closing, self-latching pedestrian gates that open outward and a 36 inch clear zone from climbable equipment.
- Under California Civil Code 841, adjoining owners are presumed to share equally in the reasonable cost of building, maintaining or replacing a shared boundary fence unless they agree otherwise in writing, and an owner planning such work must give each affected neighbor at least 30 days' prior written notice describing the problem, the fix, estimated costs, the cost-sharing proposal and the timeline.
- CSLB defines the C-13 Fencing classification as a contractor who constructs, erects, alters or repairs all types of fences, railings, guard rails, barriers, posts and gates, excluding masonry walls.
How tall can a fence be in Aliso Viejo, in the front yard and the backyard?
The City's Fences and Walls handout limits fences to 6 feet in side and rear yards and 42 inches within front yard setbacks, measured from finish grade at the base. Fences less than 30 inches apart count as one structure, so a double fence with a narrow gap does not buy extra height. The handout's wood fence detail also shows 72 inches as the maximum with no permit.
State rules are looser, and that causes confusion. Section R105.2 of the 2025 California Residential Code, as shown on a third-party code site, exempts fences up to 7 feet from a building permit, which is where many online '7 foot fence' answers come from. The City's own limit still applies, so ask Planning before designing anything taller. An archived copy of municipal code Chapter 15.14 (February 7, 2025) says fences above the limits, up to 10 feet, need an exception permit from the director, and fences over 10 feet go to the City Council as a site development permit with a public hearing.
Ask Planning for the height limit that applies to your lot, in writing, before posts are ordered.
Do I need HOA approval or a permit before building a fence in Aliso Viejo?
Plan for more than one approval. Planning wants a Zoning Compliance Application, form PS-240, before plans reach Building, and the form lists 'fence or wall' as a project type and asks for association approval of exterior changes other than like-for-like. The residential submittal checklist, updated December 31, 2025, says owners need not submit an HOA letter, yet it adds that a permit never relieves owners of CC&Rs or master and sub-HOA rules. The documents differ, so ask the counter at 949-425-2525 whether to bring the letter.
Where a building permit applies, the handout says to file on the portal under 'Residential - Miscellaneous Structures' with a site plan showing property lines, setbacks and total height, elevations, structural details and footing information. The City's Building and Safety page lists the counter hours and the online portal. Because the Community Association maintains most slopes, confirm the lot line with a survey before setting a post beside one.
What fence styles and materials are banned in front yards in Aliso Viejo?
The archived Chapter 15.14 bans barbed wire, razor wire and electrified fencing except where law requires them, and it bans chain link in residential districts in any front yard or any area visible from a public street. It also limits fences to 30 inches inside the street-corner sight triangle, so a corner lot's fence may sit lower than a neighbor's on a straight street. That archive may be out of date, so confirm with the City.
Style rules beyond that sit with the association, because PS-240 sends exterior changes to it. We found no published village fence palette on the City's pages, so ask your association for its approved colors, heights and picket styles before choosing a design. A low front yard fence at 42 inches or less has to clear both layers.
What are the fence and retaining wall rules on a slope in Aliso Viejo?
The handout says retaining walls not over 48 inches, measured from the bottom of the footing, with no surcharge or top or toe of slope, need no building permit, and the archived code permits retaining walls up to 6 feet. A retaining wall over 30 inches high that is visible off site must be landscaped with automatically irrigated shrubs or vines. The handout also warns that a building permit may be required next to slopes and that a licensed engineer's soils report may be required.
Soils add a question mark. The City's hazard plan says most developed land was mass graded in the past 30 years, with small areas of shallow instability in the northwest and high liquefaction potential along the Aliso Creek watershed on the eastern and western borders, yet the City's addition checklist cites expansive soils and sulfates. The two documents differ, so ask which footing standard applies to your lot. The handout measures fence height from finish grade at the base, so ask Planning how a fence set on top of a retaining wall is measured before you design one.
Do I need a permit for a block wall or masonry fence in Aliso Viejo?
A masonry fence under 72 inches does not need a permit, according to the City's handout, but it must still meet the building codes. Anything taller is a question for Building and Safety. The City's masonry details set the build: footing concrete of at least 4,500 psi with Type V cement and a 0.45 water-cement ratio, footings extending at least 24 inches into undisturbed natural soil compacted to 90 percent, and expansion joints every 25 feet.
Block walls are masonry work, and CSLB's C-13 fencing classification excludes masonry walls, so MDG brings in a licensed masonry subcontractor for them. Save the concrete trip ticket or receipts for the inspector, as the City tells patio cover builders to do for footings. Plan for hauling too: the City's demolition packet requires 65 percent diversion and CR&R bins if an old wall comes out.
What pool fence rules apply in Aliso Viejo?
A permit is required for any fence that forms part of a pool enclosure. Exhibit A of the City's code ordinance, as posted by OCFA in December 2025, requires a residential pool barrier at least 60 inches high with no more than 2 inches of clearance at the bottom and openings that stop a 4 inch sphere, with self-closing, self-latching pedestrian gates that open outward and a 36 inch clear zone from climbable equipment.
Openings, not looks, decide the material: any picket or rail spacing has to stop a 4 inch sphere, and a gate needs hardware that closes and latches by itself. PS-240 also lists pool, spa and pool equipment among its project types, so the association may review how the barrier looks.
Have the inspector's expectations for gate swing and latch height written on the plan.
How much does fence installation cost in Aliso Viejo, and how do I choose a fence company?
We found no Aliso Viejo fence price survey, so we use Los Angeles sources. Angi's Los Angeles page, updated August 4, 2026, shows an average of $3,051 (typically $1,734 to $4,422) and a $15 to $60 range per foot, with 100 feet at $2,100 to $2,350, and wood at $1,600 to $2,500 against vinyl at $1,850 to $3,400. Blending Angi, HomeGuide, Thumbtack and Fixr, we plan around $25 to $55 a 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. The Bureau of Labor Statistics put the mean wage for fence erectors in the Los Angeles area at $28.00 an hour in May 2025, a check on labor, not a price.
Material matters here: UC IPM says drywood termites are most prevalent in southern California and infest decks and fences, so use termite-resistant wood or concrete footers where wood meets soil. Fencing is CSLB class C-13, and Business and Professions Code 7159.5 caps a down payment at $1,000 or 10 percent of the price, whichever is less. Use our contractor license guide to confirm a C-13 license before signing, and read how general contractors use subcontractors to learn who stands behind the crew.

Aliso Viejo fence questions, answered
Do I need a permit to build a fence in Aliso Viejo?
Often not for a wood fence at 6 feet or less, but a pool barrier always needs one. The City's handout says masonry fences under 72 inches need no permit and its wood fence detail shows 72 inches as the maximum without one. Taller fences and any walls near slopes are questions for Building and Safety.
How tall can my front fence be in Aliso Viejo?
Forty-two inches inside the front yard setback, measured from finish grade at the base, according to the City's Fences and Walls handout. Side and rear yards can go to 6 feet. Corner lots add a 30 inch limit inside the street-corner sight triangle in the archived code, so check your lot before you design.
Can I put up a 7ft fence?
Not simply. The state exempt-work list, as shown on a third-party code site, exempts fences up to 7 feet from a building permit, but the City limits side and rear fences to 6 feet. The archived code lets the director grant an exception up to 10 feet. Ask Planning before you order materials.
Do you need a permit to build a block wall in California?
It depends on the city. In Aliso Viejo the City's handout says masonry fences under 72 inches need no permit, though they must meet the building codes and its footing details of 4,500 psi concrete and 24 inch embedment. Taller walls, or walls beside slopes, can require a permit and an engineer's soils report.
What is the maximum height of a retaining wall without a permit?
In Aliso Viejo, 48 inches measured from the bottom of the footing, when there is no surcharge and no top or toe of slope, according to the City's handout. The archived code permits walls up to 6 feet. A wall over 30 inches that is visible off site must be landscaped with irrigated shrubs or vines.
How much does it cost to have 100 feet of fence installed?
Angi's Los Angeles page puts 100 feet at $2,100 to $2,350, and our blended planning range of $25 to $55 a foot for a 6 foot wood or vinyl privacy fence gives roughly $2,500 to $5,500. No Aliso Viejo fence survey turned up, so the measured written proposal sets the real price.
Is it cheaper to install a wood or vinyl fence?
Wood usually costs less up front. Angi's Los Angeles page shows wood fencing at $1,600 to $2,500 and vinyl at $1,850 to $3,400 for typical jobs. Southern California termites infest wood fences, according to UC IPM, so keep wood off the soil or use concrete footers, and compare maintenance as well as the first price.
What happens if I don't have a permit for a fence?
When a permit was required, the City's code exhibit allows an assessment of double the permit fees for starting work without one. The Code Enforcement page lists work without permits among its common cases, with citations that start at $100 and escalate if a violation is not corrected. Confirm first whether your fence needs one.
Does my HOA need to approve my fence?
Almost certainly, because the Planning form PS-240 lists fences and walls and asks for association approval of exterior changes other than like-for-like work. The City's checklist says no HOA letter is required at submittal but that a permit never relieves you of CC&Rs. Ask your association for its written fence rules.
Can I put a privacy fence up in my front yard?
Not a tall one. Front yard fences are limited to 42 inches within the setback, which is too low for privacy. The archived code also bans chain link in any residential front yard or area visible from a public street. A solid 6 foot fence belongs in the side or rear yard.
