TL;DR
- City of San Diego: Municipal Code Table 142-03A, no fence-division permit under 7 feet; building permit at 7 feet and up. You can still violate front-yard or sight-triangle height without needing that permit.
- Unincorporated County: PDS 070, building permit except fences and freestanding masonry walls not exceeding 6 feet that meet zoning.
- Front-yard height is a zoning cap (City solid-on-the-line generally 3 feet; County front/exterior side 42 inches), not the same number as the permit trigger.
- Pool barriers follow the Swimming Pool Safety Act (HSC 115922 and 115923), not a Title 24 guess on this page.
- HOA approval is a separate process and is often stricter.
- A licensed C-13 or other properly licensed contractor may pull permits if the contract says so. Fence Pros San Diego does not.
Fence permit rules in San Diego County confuse homeowners because each desk writes them differently. Here is what the saved City and County documents actually say, plus the state pool statutes in the job file.
The short version
- City of San Diego, fence under 7 feet: no permit required by the fence division (Table 142-03A). Height in that yard still has to be legal.
- City, fence 7 feet or greater: building permit, Process One.
- City, retaining wall 3 feet or greater: building permit.
- City, coastal strip between the shoreline and the first public roadway (Map C-731): Coastal Development Permit path in Table 142-03A.
- Unincorporated County: permit required except fences and freestanding masonry walls not exceeding 6 feet that comply with zoning (PDS 070).
- County zoning heights in that bulletin: 42 inches front or exterior side yard; 72 inches rear or interior side yard.
- Any street-corner visibility area (City): 3 feet.
- Pool: if the fence is an isolation enclosure, HSC 115923. If a building permit is issued for a new or remodeled private single-family pool or spa, HSC 115922 two-feature rule.
- HOA: separate from the city, and often stricter.
Other incorporated cities (Carlsbad, Encinitas, Chula Vista, and the rest) have their own counters. Use permit rules by city and then call that city. A contractor who will not name the jurisdiction is not ready to quote.

Height rules (zoning) vs permit rules
City of San Diego (142.0310), simplified:
- Solid fence on the front or street-side property line: generally 3 feet, with drawn exceptions as the fence steps back toward the setback or on some lots abutting a major street, arterial, or freeway.
- Open fences (not standard all-metal chain link): up to 6 feet on that property line; may rise toward 9 feet at the setback. Coastal Overlay: at least 75 percent of vertical surface open to light; elsewhere 35 percent.
- Required side and rear yards: up to 9 feet, open above 6 feet.
- Visibility areas: 3 feet.
Unincorporated County (PDS 070 / ZO §6708):
- Front or exterior side yard: 42 inches
- Rear or interior side yard: 72 inches
- Main building area: up to the main-building height, where that section applies
Pool enclosure (state law, if used): 60-inch minimum, plus the rest of 115923. Not a substitute for local zoning.
Setback and easement notes
Most San Diego desks allow a backyard fence on the property line if height is legal. That is not a license to block a recorded easement.
- Front-yard fences that exceed the zoning cap often have to step back or go through a permit or variance. The City draws a height line from 3 feet at the property line to 6 feet at the setback for solid fences.
- Corner lots add a visibility triangle.
- Utility and drainage easements can require removal with no payment if you blocked access. Read the title before you pour.
Pool barrier law (HSC 115922 and 115923)
Do not cite Title 24 as the home of these numbers on this page. The job file has Health and Safety Code 115922 and 115923.
115923 enclosure: gates open away from the pool; self-closing; latch no lower than 60 inches; height at least 60 inches; max 2 inches from grade to the bottom of the enclosure; no 4-inch-sphere gaps; no climbable outside face for a child under five.
115922: when a building permit is issued for construction or remodeling of a private single-family pool or spa, at least two of seven drowning-prevention features. An isolation enclosure is one option. Some pairs do not count. Details: California pool fence code.
Adopted local pool-barrier checklists can add mesh or climbability tests. Ask the inspector. Independent contractors install through pool fence. This site does not certify barriers.
HOA approval
If you have an association, written approval is a second gate. HOA fence approval is the process post. Common CC&R topics: material, color, height cap, picket profile, both-sides-finished construction, and a review window. Those windows are set by your association, not by a county-wide 14-to-30-day rule on this blog.
The contractor may pull CC&Rs if you hire them to. If they will not, you do it before you sign.
Common permit mistakes
- Assuming no one is watching. A neighbor complaint or a sale inspection can surface an illegal height. We do not publish a fine schedule.
- Building first, permitting later. Some desks allow after-the-fact permits at a higher fee. Pull first when a permit is required.
- Ignoring easements. A fence across a utility easement can be removed.
How permit pulls typically work
The independent contractor you hire should name the jurisdiction before quoting. If a permit is needed, it should be in the contract as included or as an allowance. The contractor submits plans if that is the agreement. We will not invent a 2-to-10-day approval clock.
For HOA properties, drawings and samples go to the architectural committee on that association’s calendar. Fold that time into the project before you schedule labor.
Fence Pros San Diego will not tell you on a five-minute call that you are “under the threshold.” That is the city’s call.
Frequently asked questions
Do I need a permit to build a fence in San Diego?
City: not from the fence division if the fence is under 7 feet, but height and location still have to be legal; 7 feet and up needs a building permit. County unincorporated: yes, unless you qualify for the not-over-6-feet exception. Front-yard, visibility, retaining-wall, coastal-overlay, and pool rules can still apply. HOA approval is separate.
How much does a fence permit cost in San Diego?
Fee schedules are published by each city and the County. We are not printing a dollar band. Ask the permit desk or put the fee on the contractor’s quote.
Do I need a permit to replace an existing fence in San Diego?
Like-for-like height and location often follow the same permit test as new work in that jurisdiction. Raising height, moving the line, sitting on a retaining wall, or building a pool enclosure can change the answer. A replacement pool barrier still has to meet current 115923 if it is an enclosure.
Do I need a permit to put up a fence in California?
There is no single statewide fence-permit rule. Cities and counties set it. Pool drowning-prevention features are statewide in the Swimming Pool Safety Act when 115922’s trigger is met.
For how permits fit with height, property lines, pool code, and HOA rules, see San Diego fence laws.
If you are unsure, call the building department for the address, then call (858) 400-4906 if you want a match with an independent contractor who can carry the paperwork in the contract.
