Fence & Deck Repair in Atherton

Fence repair in Atherton often involves more than boards and posts: long street frontages, gates and columns, heritage oaks near the fence line, and a permit for any fence within 10 feet of a public street. Send photos of the damaged section, the gate if it is involved, and any large tree nearby, and the independent contractor who covers Atherton replies with the likely scope before the first visit. For a new fence rather than a repair, see fence installation in Atherton.

Six feet along the street. Atherton's municipal code allows fences up to 6 feet along a front lot line or public street, not only along side and rear lines (AMC § 17.46.030, Table 17.46.030-1, current through Ordinance 679, May 20, 2026). Fences can reach 8 feet along the town boundary and next to schools and the railroad. At street intersections the limit drops to 3 feet. A fence over 6 feet must be screened from public view by plants that reach full height within three years.

Seven regulated streets. El Camino Real, Marsh Road, Middlefield Road, Valparaiso Avenue, Alameda de las Pulgas, Bay Road and Ringwood Avenue have their own height rule: 6 feet above natural grade or 8 feet above the elevation of the adjacent pavement centerline, whichever is higher (AMC § 17.46.030, Table 17.46.030-1, note 2).

Permits near the street. The Town requires a building permit for any fence within 10 feet of a public right-of-way, and for any fence, gate or column over 6 feet, with a site plan, elevations and structural calculations.

Gates and columns. Gates, posts and columns can be up to 10 feet tall, including a light fixture of no more than 18 inches. They must sit at least 30 feet back from a corner intersection. Vehicle gates need a clear opening of at least 16 feet, and a gate may not swing over the public right-of-way. A repair that changes a gate's swing, width or column height is a design change, not just a repair. Gate problems here have their own page: gate repair in Atherton.

Heritage oaks. Under the Town's Heritage Tree Preservation Standards (2023), valley, coast live and blue oaks with a trunk of 48 inches in circumference or more are heritage trees. The tree protection zone is a radius of 10 times the trunk diameter. Trenching closer than that must be hand-dug, with a project arborist involved. A new post hole near a large oak falls under those rules.

Fences on Town property lines. A fence shared with the Town is not a private-neighbor fence. In 2017, owners on Felton Drive asked to replace about 240 feet of fence on the line with Holbrook-Palmer Park; because it sat on a Town property line, it needed Town authorization separate from the building permit (City Council staff report, June 21, 2017). California's Good Neighbor Fence Act excludes public agencies, so any cost-sharing with the Town is negotiated, not presumed.

Maintenance. The code requires fences and walls to be kept in orderly and good condition.

Full height and setback details are on the Atherton fence rules page.

• Measure the distance from the fence to the edge of the street; inside 10 feet, plan for a permit.
• Photograph any oak within about 20 feet of the work and note its approximate trunk size.
• For gate problems, photograph the gate open and closed, the columns, and the operator if it is automatic.
• If the fence borders Town land, start with the Town before getting bids.

Can I rebuild my front fence at 6 feet in Atherton?
The code allows 6 feet along a front lot line or public street, with lower limits at intersections and special rules on the seven regulated streets. Within 10 feet of the street a building permit is required.

Does a new post near an oak need an arborist?
If the tree is a heritage tree and the work is inside its tree protection zone, the Town's standards require hand digging and arborist involvement. The zone is 10 times the trunk diameter.

Who pays for a fence shared with Holbrook-Palmer Park or other Town land?
The Good Neighbor Fence Act does not apply to public agencies. Any split with the Town is by agreement; the 2017 Felton Drive request shows the Town considering options such as sharing cost or waiving permit fees.

Atherton's entry gates are the heaviest on the Peninsula — long leaves, light fixtures on the posts, often an operator hanging off them — and a hinge post carrying that load wears out faster than any post in a fence line. Two jobs come out of it, and they are worth telling apart. A gate that drags, sticks or won't latch is usually the post rather than the leaf, and re-hanging it in place leaves height, material and position as they are. A gate that is genuinely past saving goes back into the opening that already exists, on a post sized for a gate rather than for a panel.

The town's own figures bound both: entry gates and posts are capped at 10 feet including light fixtures, the fixtures themselves at 18 inches, and no more than two lights to an entrance. A gate that goes back inside those numbers, in the same opening, stays inside the town's limits. A gate in that fence line that sags, drags or misses its latch is a repair of its own: see gate repair.

Repairing an existing fence — posts, boards, gate hardware, like-for-like — leaves its height and location as they are. A new or relocated fence within 10 feet of the public right-of-way, or anything over 6 feet, needs a building permit, and the code requires zoning clearance for fences, gates and posts outside its exemptions (AMC § 17.46.020). Estate fencing here also fails differently: long runs, mature irrigation systems, and heavy planting against the fence line mean rot at the soil line and vegetation load are the usual culprits, and gates — large, heavy, often automated — wear their hinge posts faster than anywhere else on the Peninsula.

Send photos through the form — the failed section, post bases, the gate and its hinge side — and the contractor for your area replies with the likely repair and a ballpark before anyone comes out.
