Fence Companyin National City, CA
A fence company in National City builds to a 4 foot limit in front and corner side setbacks and 8 feet elsewhere in setback areas. Fences up to 7 feet are exempt from a building permit in the City's Info Guide, but the zoning code says every masonry wall needs one, and Old Town bans chain link entirely.
A fence in National City goes up against old lots and tight neighbors. The Census Bureau's ACS 2024 five-year estimates count 19,414 housing units, and only 40.4 percent are single-family detached, while 37.6 percent sit in buildings of five or more units and 65.3 percent of occupied homes are rented. Fence requests therefore often start with a landlord, and the zoning code adds screening rules where apartments meet single-family blocks.
On a fence job, MDG Builders (CSLB #1040337) checks the height rules, files any permit and holds the schedule, while a licensed C-13 fencing subcontractor, or a masonry specialist for a block wall, does the building. Our fencing page holds the sourced prices, the National City overview lists every trade we manage here, and the guides for Chula Vista, Lemon Grove and Imperial Beach show how neighbors treat fences. The City's Building Division handles permits. The City's site blocked automated requests, so the zoning text came from a third-party mirror of the code and the handouts from Internet Archive copies. Confirm any height with the City before posts go in.
What National City's fence chapter, Info Guide and Engineering rules say about fences
Where fencing permits come from in National City: City of National City Community Development Department, Building Division.
- The Info Guide (July 2023) says fences over 7 feet need a building permit and fences not over 7 feet are exempt (with CMU fences exempt only under 4 feet), and for fences over 4 feet in a front yard setback it says to contact Planning for special review.
- The Land Use Code (Section 18.43.040, Ordinance 2024-2529, GoCodebook mirror) says all masonry walls must meet the California Building Code and all masonry walls require a building permit, which is broader than the Info Guide's exemption for CMU fences under 4 feet. The two documents differ for low masonry walls, so treat any block wall as a permit item and confirm.
- Fence and wall height in National City (Section 18.43.050): up to 8 feet is allowed in setback areas, but in a front setback or the exterior side setback of a corner lot the limit is 4 feet, except a residentially developed property in a residential zone may have a fence, wall or hedge up to 6 feet in the exterior side setback of a corner lot. Over 4 feet is not allowed in the rear setback of a reversed corner lot that abuts the front setback of the lot behind it, and up to 30 percent of a fence's length may exceed the limit by up to 6 inches.
- Fences on retaining walls (Section 18.43.050): retaining wall height counts toward fence height, a fence placed on or within one foot of the face of an above-ground retaining wall in a required yard is measured to the midpoint height of the wall, and masonry walls may not exceed 8 feet in total, or 6 feet of masonry plus a 2 foot 8 inch retaining wall when they include one.
- Section 18.43.040 requires fences to be built of new or good used material and kept in good repair (dilapidated, dangerous or unsightly fences must be removed or repaired), wood fences to use pressure-treated posts set in concrete footings, and allows vinyl; chain link is allowed only in 9-gauge wire with 3.5 by 5 inch mesh and redwood slats for screening residential or industrial areas.
- Section 18.43.060 prohibits barbed wire, electrified fence and concertina or razor wire in residential and commercial zones unless required by law, and in the Westside Specific Plan area (the Old Town area) it prohibits chain link, barbed wire and razor wire fencing altogether.
- Screening fences (Section 18.43.020): where a commercial or industrial side or rear setback abuts a residential zone, or a multifamily use abuts a single-family zone, the City requires an opaque fence or wall at least 6 and no more than 8 feet high.
- Retaining walls are handled through Engineering: a retaining wall plan is required for walls over 3 feet (footing to top) and for walls of 3 feet or less that support a surcharge or sloped backfill, and a level-backfill wall of 3 feet or less that is not part of a building is exempt from a grading permit but must follow the Regional Standard Drawings and is subject to City inspection (Chapter 15.70, Ordinance 2019-2471, GoCodebook mirror).
How tall can a fence be in a National City front yard or corner lot?
Four feet in a front setback, and four feet in the exterior side setback of a corner lot. Section 18.43.050 of the Land Use Code allows up to 8 feet in setback areas generally, then pulls the front and corner-side areas down to 4. A residentially developed property in a residential zone gets one relief: up to 6 feet in the exterior side setback of a corner lot, and that covers a fence, wall or hedge.
Three smaller rules matter at the tape measure. A fence may not exceed 4 feet in the rear setback of a reversed corner lot that backs onto the front setback of the lot behind it. Up to 30 percent of a fence's length may exceed the limit by up to 6 inches, which helps on sloped runs. And for a fence over 4 feet in a front yard setback, the Info Guide says to contact Planning for special review at (619) 336-4310.
Ask for the setback line to be marked on the plan before the gate swing is chosen.
Can I install a chain link fence in National City?
Not in the Westside Specific Plan area, which is Old Town. Section 18.43.060 prohibits chain link, barbed wire and razor wire fencing there outright. Elsewhere chain link is allowed only in 9-gauge wire with 3.5 by 5 inch mesh, and redwood slats are the accepted screening for residential and industrial areas. Barbed wire, electrified fence and concertina or razor wire are barred in residential and commercial zones unless another law requires them.
Section 18.43.040 sets the build rules for everything else. Fences must be new or good used material and kept in good repair, and a dilapidated, dangerous or unsightly fence must be removed or repaired. Wood fences need pressure-treated posts set in concrete footings, and vinyl is allowed. Old Town is where the Westside Specific Plan of 2010 tries to preserve turn-of-the-century homes, so a replacement fence there is a design choice as much as a code question.
Check whether the address sits inside the Westside plan area before pricing chain link.
Does a fence need a building permit in National City, and what about 7 feet?
Fences not over 7 feet are exempt, and taller ones need a permit. The Info Guide, dated July 2023, says so, with one exception for CMU fences, which it exempts only under 4 feet. Zoning lets a fence reach 8 feet in a side or rear setback, so a fence between 7 and 8 feet is legal on the lot but still permit work. The Building Department fee schedule effective August 11, 2025 has lines for non-masonry fences or freestanding walls over 7 feet and masonry ones over 4 feet, which agrees with that split.
That is where the City's documents part ways on block. The Land Use Code, in section 18.43.040, says all masonry walls must meet the Building Code and all masonry walls require a building permit, with no height floor. The Info Guide exempts a low CMU fence, and the code does not. Treat any block wall as a permit item until the Building Division tells you in writing otherwise, and note that the Info Guide predates the 2025 codes.
Ask for the written answer on low block walls before ordering block.
How tall can a block wall or retaining wall be in National City?
Masonry walls may not exceed 8 feet in total, or 6 feet of masonry on top of a 2 foot 8 inch retaining wall when the wall includes one. Retaining wall height counts toward fence height, and a fence placed on or within one foot of the face of an above-ground retaining wall in a required yard is measured to the wall's midpoint height. Stack a fence on a wall and the combined number is what the City checks.
Retaining walls run through Engineering, which handles grading and drainage. A plan is required for walls over 3 feet from footing to top, and also for walls of 3 feet or less that hold a surcharge or sloped backfill. A level-backfill wall of 3 feet or less that is not part of a building is exempt from a grading permit but must follow the Regional Standard Drawings and is subject to City inspection. Masonry is not C-13 work, since that fencing class excludes masonry walls, so a block wall goes to a licensed masonry specialist.
Price the footing depth and the wall type on separate lines.
Who pays for a shared fence in National City, and when does the City require screening?
Usually the neighbors split it. California Civil Code section 841, shown on FindLaw, presumes adjoining owners share the reasonable cost of a boundary fence equally. A landowner planning to incur costs must give each affected neighbor 30 days' prior written notice with a description of the problem, a cost estimate and a proposed split. Send that notice by a method that proves delivery, because with 65.3 percent of homes rented the neighbor you must notify is often a landlord.
Screening is a separate duty. Section 18.43.020 requires an opaque fence or wall at least 6 and no more than 8 feet high where a commercial or industrial side or rear setback abuts a residential zone, or where a multifamily use abuts a single-family zone. With 37.6 percent of units in buildings of five or more, that second case comes up on block edges across the city.
What should I know about replacing a fence on an older National City lot?
Lots here are older than the fence on them. The City's pages date the city to 1868 and its incorporation to September 17, 1887, and ACS 2024 puts 70.1 percent of units before 1980 and 8.0 percent in 1939 or earlier. The Westside has single-family homes from around the turn of the century beside auto services and warehouses. Brick Row, ten row houses Frank Kimball built in 1887, carries a protective covenant on its facade, and we found no fence design review for the 56 locally designated buildings, so ask before changing a street-facing fence on one.
Check three things before demolition. Flood overlays marked -FW, -FF-1 or -FF-2 require a development permit before any building or grading permit, so ask whether a fence in one needs it. Coastal zone parcels west of Interstate 5 sit under the Local Coastal Program, whose fence rules we did not read. And a fence beside a driveway or sidewalk may touch the public right-of-way, which Engineering reviews at (619) 336-4380.
Ask the fence company to confirm the property line from a survey, not from the old fence.
How much does fence installation cost in National City, and who builds it?
We found no National City price survey, so these numbers come from Los Angeles and a local bid may differ. Angi's Los Angeles guide, updated August 4, 2026, gives a typical fence project at $1,734 to $4,422, or $15 to $60 a linear foot, and shows 100 feet at about $2,100 to $2,350. For a labor check, federal data lists Los Angeles area fence erectors at a mean of $28.00 an hour in May 2025. Our planning ranges are $25 to $55 a foot for wood or vinyl privacy fence, $12 to $30 for chain link and $35 to $85 for aluminum or iron. We found no independent price for block walls, so we print none.
Fencing is CSLB class C-13, and Business and Professions Code 7159 caps a down payment at $1,000 or 10 percent of the price, whichever is smaller. Use our contractor license guide to verify a license and read how general contractors use subcontractors to see who answers for the crew.

Where these National City fence figures come from
Every fence price we use sits on the fencing page with its source and date. New fencing often comes with other outside work, and the National City rules for it are on the roofing page, the painting page and the kitchen remodeling page. For the next city north, which measures fence heights differently, read the guide for San Diego.
| What it covers | Typical range |
|---|---|
| Wood or vinyl privacy fence, 6 feet | $25 to $55 per linear foot |
| Chain-link | $12 to $30 per linear foot |
| Aluminum or ornamental iron | $35 to $85 per linear foot |
| Typical 100-foot backyard run | $2,500 to $5,500 total |
| Block walls, horizontal slat fences, gates and openers, hillside lots | Set by the written proposal |

National City fence questions, answered
Do I need a permit to build a fence in National City?
Not for most fences of 7 feet or less, according to the City's Info Guide, but every masonry wall needs one under the zoning code. The guide is dated July 2023 and predates the 2025 codes. Confirm the height and the material with the Building Division at (619) 336-4210 before building.
How tall can my front fence be in National City?
Four feet in a front setback and in the exterior side setback of a corner lot. A residentially developed lot in a residential zone may go to 6 feet in the corner-side setback. Elsewhere in setback areas the cap is 8 feet. Over 4 feet in a front yard calls for Planning review.
Can I put up a 7ft fence?
Yes in a side or rear setback, since the City exempts fences not over 7 feet from a building permit and zoning allows up to 8 feet there. Not in the front setback, where 4 feet is the limit. A 7 to 8 foot fence is allowed but needs a permit.
Is chain link allowed in National City?
Yes in most places, but not in Old Town. The Westside Specific Plan area bans chain link, barbed wire and razor wire fencing, and elsewhere chain link must be 9-gauge wire with 3.5 by 5 inch mesh and redwood slats when used for screening. Barbed and razor wire are barred in homes and shops.
Does your neighbor have to pay for half the fence in California?
Usually yes for a boundary fence. Civil Code 841 presumes adjoining owners share the reasonable cost equally, and the owner who plans the work must give each affected neighbor 30 days' written notice with the problem, a cost estimate and the proposed split. Agreements can differ, so put them in writing.
What is the maximum height of a retaining wall without a permit?
In National City a level-backfill wall of 3 feet or less that is not part of a building is exempt from a grading permit, but it must follow the Regional Standard Drawings and is inspected. Walls over 3 feet, or any wall holding a surcharge or sloped backfill, need a retaining wall plan.
Do you need a permit to build a block wall in California?
In National City, treat it as yes. The Land Use Code says all masonry walls require a building permit, while the City's Info Guide exempts a CMU fence under 4 feet. The two documents differ, so get the Building Division's answer in writing. Masonry walls also may not exceed 8 feet in total.
How much does it cost to have 100 feet of fence installed?
A 100 foot run shows up in Angi's Los Angeles guide at roughly $2,100 to $2,350, while our $25 to $55 a foot planning range puts a wood or vinyl privacy run near $2,500 to $5,500. A National City bid may differ, and gates, slopes and removing an old fence add cost. The written proposal sets the price.
Is it cheaper to install a wood or vinyl fence?
Wood is usually cheaper up front. Angi's Los Angeles guide shows a wood fence at $1,600 to $2,500 and vinyl at $1,850 to $3,400. National City allows vinyl and requires pressure-treated posts set in concrete footings for wood, so ask each bid to name the post material and footing depth.
