Fence Companyin Coronado, CA
A fence company in Coronado needs a building permit for any fence over 24 inches, far below the State model list. Front yard fences stop at 4 feet, side and rear yards allow 8, corner lots keep a 3 foot sight triangle and hedges count as fences. Retaining walls over 24 inches need a permit too.
Fences in Coronado follow a street grid that the City's own ADU ordinance says was laid out more than 100 years ago, on an island reached only by the Coronado Bridge or State Route 75. The Census Bureau's ACS 2024 five-year estimates count 9,896 housing units, 45.8 percent single-family detached, 12.4 percent attached and 36.1 percent in buildings of five or more, and 45.4 percent of occupied units are rented, so a fence request often passes through a landlord first.
On a fence job, MDG Builders (CSLB #1040337) checks the height rules, files the permit and keeps 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 Coronado overview lists every trade we manage here, and the guides for San Diego and Imperial Beach show how neighbors treat fences. The City's Building Services Division issues the permit and its Planning and Zoning page covers setbacks. The City website blocks automated readers, so we read archived copies dated April to August 2026 and the Municipal Code through a third-party mirror. Confirm anything that matters with the City.
What Coronado's fence handouts, zoning code and historic rules say about fences
Where fencing permits come from in Coronado: City of Coronado Community Development Department, Building Services Division.
- Coronado requires a building permit for any fence, regardless of material, greater than two feet (2 ft) in height, including demolition and reconstruction (Handout 112, March 2025); Municipal Code 70.20.030 amends the model code to exempt only fences not over 2 feet and retaining walls not over 2 feet (measured from the bottom of the footing, unless supporting a surcharge or impounding flammable liquids).
- Handout 301 (Permits Required / Exempted Work, March 2025) says fences not over 24 inches high are exempt as a City of Coronado modification to the model code, and retaining walls not over 24 inches measured from the bottom of the footing are exempt unless supporting a surcharge.
- Fence permit paperwork in Coronado is a construction permit application, a site plan, a construction valuation form (Handout 107) and the Fence Construction Certification (Handout 112); boundary surveys are recommended but not required, disputes over fence location are a civil matter, and a fence straddling the common property line needs signed approval from the adjacent owners.
- Municipal Code 86.56.165: fences, walls or hedges in the required front yard cannot exceed 4 feet, except a fence or wall up to 6 feet along a side property line that projects into the front yard 8 feet and stays at least 10 feet from the front property line, and lots fronting solely on an alley or on listed streets (Third Street between A Avenue and Alameda Boulevard, all of Fourth Street, Alameda Boulevard between Third and Fourth Street, Pomona Avenue between Third and Fourth Street) may enclose the front yard with an 8-foot wall, fence or hedge if landscaping buffers it from the public right-of-way.
- Municipal Code 86.56.160 and 86.56.170: in residential zones a fence, wall or hedge may be 8 feet in a required side or rear yard (hedges in rear yards that abut an alley up to 10 feet) and 6 feet in a required street side yard on a corner lot (8 feet on the listed Third Street, Fourth Street, Alameda Boulevard and Pomona Avenue blocks); the City's fence handout says the height and location rules apply to hedges and other plant material used as fencing.
- Municipal Code 86.56.175: on residential corner lots, fences, walls and hedges cannot exceed 3 feet in height inside the triangle formed by points on the street curb lines 50 feet from the corner (single-stem plants or trees with no foliage between 3 and 8 feet are allowed).
- Handout 3 (Fences, November 2, 2017): wood posts must be treated or No. 2 foundation-grade redwood or pressure-treated Douglas fir-larch No. 2 or better, set in footings 12 inches in diameter and 24 inches deep (4 to 6 foot fences) or up to 42 inches deep (7 to 8 foot fences), over 3 inches of loose gravel; footing and final inspections are required and any deviation needs an engineered plan stamped by a California engineer or architect. Design criteria are 85 mph wind Exposure C and Seismic Design Category D.
- Handout 301 says a Storm Water Assessment form (I-1 and I-2) must accompany a fence permit application if the work disturbs more than 200 square feet of soil, includes landscaping, hardscape or minor grading, or imports or exports soil (Storm Water Review desk 619-522-2653), and storm water pollution prevention guidelines apply even to minor fence work.
How tall can a front yard fence be in Coronado?
Four feet, with a few exceptions. Municipal Code 86.56.165 caps a fence, wall or hedge in a required front yard at 4 feet. A fence or wall up to 6 feet is allowed along a side property line where it projects into the front yard 8 feet and stays at least 10 feet from the front property line. Lots that front only on an alley, or on certain listed blocks, may enclose the front yard at 8 feet if landscaping buffers it from the public right-of-way.
The listed blocks are Third Street between A Avenue and Alameda Boulevard, all of Fourth Street, Alameda Boulevard between Third and Fourth Street, and Pomona Avenue between Third and Fourth Street. The City's fence handout says the height and location rules apply to hedges and other plant material used as fencing, so a tall privet counts like a wood board. In the R-1A zone, 40 or 60 percent of the area between the house and the front line, depending on lot width, must also be planted or hold water features.
Have the plan mark the front property line and the 4 foot height before posts are ordered.
How tall can a backyard or corner lot fence be in Coronado?
In residential zones, 8 feet in a required side or rear yard. Sections 86.56.160 and 86.56.170 allow hedges up to 10 feet in rear yards that abut an alley, and set 6 feet in a required street side yard on a corner lot, rising to 8 feet on the same listed Third Street, Fourth Street, Alameda Boulevard and Pomona Avenue blocks.
Corners carry a stricter cap. Section 86.56.175 holds fences, walls and hedges to 3 feet inside the triangle formed by points on the two curb lines 50 feet from the corner, with an exception for single-stem plants or trees that have no foliage between 3 and 8 feet. The fence handout is dated November 2, 2017, older than the March 2025 handouts, but its height numbers match the current code text we read in the mirror, which is current through Ordinance 2026-05.
Ask the designer to draw the 50 foot triangle on a corner lot before the gate swing is set.
Do I need a permit to build a fence in Coronado, and what gets inspected?
Yes, for anything over 2 feet. Handout 112, the City's fence certification form dated March 2025, requires a building permit for any fence over 2 feet in height, regardless of material, including demolition and reconstruction. Municipal Code 70.20.030 amends the model code so only fences not over 2 feet are exempt, while the State model list exempts fences up to 7 feet. Handout 301 uses the same 24 inch line for retaining walls, measured from the bottom of the footing, unless the wall supports a surcharge.
The paperwork is a construction permit application, a site plan, the valuation form (Handout 107) and the Fence Construction Certification. Handout 302 lists fences among the over-the-counter jobs, averaging 15 to 30 minutes of review. Footing and final inspections are required, and any departure from the handout's standard details needs a plan stamped by a California engineer or architect.
Ask who requests the footing inspection before any concrete is poured.
Who pays for a shared fence in Coronado, and where is the property line?
The City stays out of boundary disputes. Its fence handout says a boundary survey is recommended but not required, calls a dispute over where a fence sits a civil matter and requires signed approval from the adjacent owners for a fence that straddles the common line. Under City Council policy, code enforcement responds only to written complaints, issues Notices of Violation and relies on voluntary compliance.
Cost sharing follows state law. California Civil Code 841 presumes that adjoining owners split the reasonable cost of a boundary fence equally unless they agree otherwise in writing, and the owner who plans the work must give each neighbor at least 30 days' written notice. With 45.4 percent of occupied units rented, the neighbor is often a landlord or an association, so keep proof of delivery with the permit file.
Keep the signed approval, the notice and the survey together with the permit.
How deep do fence posts go in Coronado, and does the fill under the island matter?
The City's handout sets the baseline. Handout 3 calls for wood posts that are treated or No. 2 foundation-grade redwood, or pressure-treated Douglas fir-larch No. 2 or better, set in footings 12 inches in diameter and 24 inches deep for 4 to 6 foot fences and up to 42 inches deep for 7 to 8 foot fences, over 3 inches of loose gravel. Masonry fence footings must reach at least 12 inches into undisturbed soil or compacted fill. The design criteria behind those details are 85 mph wind, Exposure C, Seismic Design Category D and soil bearing pressure of at least 1,500 psf.
Wikipedia says the Country Club area, the Glorietta area and golf course, most of Naval Amphibious Base Coronado, most of the Strand naval housing and most of Coronado Cays sit on dredged bay material. None of the City handouts we read names a soils rule, so that is context, not a permit requirement. A Storm Water Assessment form, I-1 and I-2, must go with the application if the work disturbs more than 200 square feet of soil, adds landscaping or hardscape, or moves soil on or off the lot.
Ask the fence company to price a deeper footing as its own line in case the soil calls for it.
Can I put a vinyl fence on an older Coronado house, and does the Coastal Zone matter?
Vinyl is the sticking point on a historic house. The City's alteration guidelines for Mills Act properties prohibit vinyl, including vinyl fences, windows, downspouts and guard rails. Owners of designated residential resources can seek a Mills Act agreement, and a resource can be designated at 75 years of age if it meets two or more criteria. Since December 4, 2025, demolishing original street-visible features on a non-Tier 3 structure that old also needs a Determination of Historic Significance, and the pages we read do not say whether replacing a front fence counts.
The Coastal Zone covers the whole city. Municipal Code 86.70.052 exempts improvements to existing single-family homes and duplexes under the Local Coastal Program, but we did not read the Land Use Plan, so we cannot say how it treats a new front wall. Federal and Port land inside the limits sits outside City coastal permit authority. Handout 3 adds that structures in Very High fire zones under Chapter 7A of the California Building Code may need extra fire protection, and the older state map data we queried shows no Very High polygon in Coronado.
Check the City's Tier map before choosing a fence material for an older Village house.
How much does fence installation cost in Coronado, and who builds a block wall?
We found no Coronado price survey, so the figures come from Los Angeles, and a bid on the island can differ. Angi's Los Angeles guide, updated August 4, 2026, shows a typical fence project at $1,734 to $4,422, or $15 to $60 a linear foot, with 100 feet near $2,100 to $2,350, wood at $1,600 to $2,500 and vinyl at $1,850 to $3,400. The federal wage survey lists fence erectors in the Los Angeles area at a mean $28.00 an hour for May 2025. For planning we use $25 to $55 a foot for wood or vinyl privacy, $12 to $30 for chain-link and $35 to $85 for aluminum or iron.
CSLB class C-13 covers fences, railings, gates and posts but excludes masonry walls, so a block wall goes to a masonry specialist under a different class. Business and Professions Code 7159 limits a contractor's down payment to $1,000 or 10 percent of the price, whichever is less. Read our contractor license guide and how general contractors use subcontractors before you sign.

| 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 |
Coronado fence questions, answered
Do I need a permit to build a fence in Coronado?
Yes, for any fence over 24 inches. Municipal Code 70.20.030 exempts only fences not over 2 feet, and Handout 112 requires a permit for anything taller, including demolition and reconstruction. Fences are on the over-the-counter list, averaging 15 to 30 minutes of review. Ask Building Services how your lot is handled.
How tall can my front fence be in Coronado?
Four feet in a required front yard, hedges included. A fence or wall up to 6 feet is allowed along a side property line that projects into the front yard 8 feet and stays 10 feet from the front line, and certain Third Street, Fourth Street, Alameda Boulevard and Pomona Avenue blocks allow 8 feet with landscaping.
Can I put up a 7ft fence in Coronado?
Yes in a side or rear yard, where the limit is 8 feet, but not in a front yard, which stops at 4 feet, and a corner lot's street side yard stops at 6. Because the City's permit line is 24 inches, a 7 foot fence needs a building permit, a footing inspection and a final inspection.
What is the maximum height of a retaining wall without a permit in Coronado?
Twenty-four inches, measured from the bottom of the footing, unless the wall supports a surcharge. Handout 301 and Municipal Code 70.20.030 set that limit, well under the 4 feet in the State model list. Taller walls need a permit and may need engineering, so ask Building Services before ordering block.
Does your neighbor have to pay for half the fence in California?
Usually, if the fence sits on the boundary. Civil Code 841 presumes adjoining owners share reasonable costs equally unless they agree in writing, and you must give 30 days' written notice before spending. In Coronado, a fence that straddles the common line also needs the adjacent owners' signed approval for the permit.
How much does it cost to have 100 feet of fence installed?
Angi's Los Angeles guide shows 100 feet at about $2,100 to $2,350, while our planning range of $25 to $55 a foot puts a wood or vinyl privacy run near $2,500 to $5,500. We found no Coronado survey, and gates, old fence removal and deeper footings add to the total.
Can I use a vinyl fence on a historic home in Coronado?
Not on a Mills Act property. The City's alteration guidelines prohibit vinyl, including vinyl fences, windows, downspouts and guard rails, and a designated Historic Resource needs a Historic Resource Alteration Permit for exterior alterations. Check your address on the City's historic map before choosing a material.
Does a pool fence need a permit in Coronado?
Pool and spa work goes through plan check, and Handout 302 lists pools, spas and fences among the projects that need it. For a new or remodeled pool, Health and Safety Code 115922 asks for at least two of seven drowning-prevention features once a permit is issued. We did not read Coronado's barrier rule, so ask Building Services.
Do hedges count as fences in Coronado?
Yes, for height and location. The City's fence handout says the rules apply to hedges and other plant material used as fencing, so a front yard hedge stops at 4 feet and a corner lot keeps a 3 foot sight triangle. Hedges in rear yards that abut an alley may reach 10 feet.
Is it cheaper to install a wood or vinyl fence?
Wood is usually cheaper up front, though the ranges overlap. Angi's Los Angeles guide shows wood at $1,600 to $2,500 and vinyl at $1,850 to $3,400. On a designated historic property in Coronado vinyl is prohibited, so the Mills Act guidelines can settle the material before price matters.
