Wood Fence Installation in Oceanside, CA

A wood fence is what most Oceanside back yards already have, and at roughly $30 to $55 a foot installed it is still the cheapest way to get six feet of real privacy. What people get wrong here is the climate. Ten inches of rain a year sounds gentle on timber. The humidity that never drops below the mid sixties, and the marine layer that sits on the west side of town most mornings in May and June, are a different story.

The normal build is six feet of upright board on four by four posts set in concrete, which is the maximum the zoning ordinance allows anywhere on a residential lot. Cedar and pressure treated pine are both common. Redwood shows up less here than it does further north and costs more when it does.

The front of the house is a completely different question, and this is where most of the confusion in this city sits. Article 10 of the zoning ordinance caps a fence in a required front yard abutting a street at 42 inches. You are allowed five feet, but only if everything above 42 inches is decorative in appearance and at least 75 percent open. A solid wood board fence is not 75 percent open, so in practice a wood fence out front stops at 42 inches.

What Actually Kills A Wood Fence In Oceanside

Several fence company sites covering Oceanside say the front yard limit is four feet. It is 42 inches, which is three and a half. The difference is small on paper and large when an inspector measures it, and it is worth checking any quote that quotes you four feet out front.

What A Wood Fence Costs Here

Moisture, and not the kind that falls out of the sky. Oceanside averages under ten inches of rain a year, almost all of it between December and March, so people reasonably assume wood has an easy life here. But relative humidity runs from about 64 percent in January to 75 percent in July, and from May into July the marine layer pushes in overnight and does not clear until late morning on the coastal side. A fence on the west side of town is damp at dawn most days for a third of the year.

Fasteners go before the wood does, and this is the single most useful thing to know before you buy. Salt in the air attacks the nails and screws holding the boards on, and it works from the inside of the joint outward where nobody looks. You end up with sound boards hanging off rusted fixings. Close to the water, hot dipped galvanized or stainless fasteners are the difference between a fence that lasts and one that sags in year six.

The soil changes what happens underground, and Oceanside has two kinds. The coastal mesas and the San Luis Rey valley are sand, marine terrace and alluvial soil, which drains fast and holds a post loosely. The inland tracts sit on expansive clay that swells when it gets wet in February and shrinks when it dries out in August. That movement works posts loose over years and is why a fence in Rancho Del Oro can lean while an identical fence in South Oceanside stands straight.

How Long It Takes

Sun is real but it is the mildest of the four. The marine layer that causes the moisture problem also shades the coastal half of town through the worst of early summer, so bare wood here silvers more slowly than it does in the inland valleys. Sealing every two to three years still pays, mostly because it slows water getting into the end grain rather than because of the sun.
