How tall can my fence be, and do I need a permit?
This is the first question on almost every estimate, and the answer depends on which side of a city limit you are on. Here is the general shape of it for the north valley, and the specific things that trip people up. Verify with your own jurisdiction before you build, or let us do it as part of the estimate.
The workhorse. Galvanized pipe set in concrete, fabric stretched tight, top rail or top wire depending on what the fence has to survive. It goes 4 feet around a dog run and 12 feet around a pickleball court, and the shop stocks the black vinyl coated version for anyone who wants it to disappear into the landscape.
The general rule
Across most jurisdictions in this area, a fence up to 6 feet in the rear and side yards, and 3 to 4 feet in the front setback, is allowed without a building permit. Above that height you are generally into permit territory, and in some places into a design review.
The height is usually measured from the grade on the higher side, and a retaining wall under a fence often counts toward the total. That last part surprises people on sloped lots.
The corner sight triangle
Where a driveway meets the street, or at a corner lot intersection, cities keep a triangle of clear visibility so drivers can see. Inside that triangle, fence height drops sharply, often to 3 feet, and it applies to hedges too. It is the single most common reason a fence has to be cut down after it is built.
Pool barriers are a separate rule
California's pool safety requirements are not a zoning question, they are a building code question, and they apply regardless of what your fence height allowance is: at least 60 inches, no gap that passes a 4-inch sphere, nothing on the outside face that works as a foothold, and a self-closing self-latching gate that opens away from the pool.
A 6-foot property line fence does not by itself make a pool compliant if the gate hardware or the gaps are wrong.
Who to ask, by jurisdiction
- Inside Chico city limits: City of Chico Community Development, zoning counter.
- Paradise and Magalia: Town of Paradise, or Butte County for unincorporated Magalia. Rebuild parcels can carry extra conditions.
- Oroville, Gridley, and Biggs: the city planning counter for each.
- Unincorporated Butte County: Butte County Development Services.
- Glenn and Tehama counties: county planning, and the city counter in Orland, Willows, Red Bluff, or Corning.
- HOAs: your CC&Rs are separate from and can be stricter than the city. Check them first.
What we do about it
We check the height allowance, the setback, and the sight triangle for your address as part of the estimate, and we say so up front if what you want needs a permit. It is a lot cheaper to find that out before the posts are in concrete.
Questions we get
Usually yes. Many jurisdictions measure the combined height of wall plus fence from the low side, or set a limit on the combination. On a lot with any grade change, ask before you design it.
Sometimes, with a permit, and sometimes not at all. A common middle path is a 6-foot solid fence with a lattice or open top section, where the open portion is treated differently. It also blocks less light for everyone.
A like-for-like replacement at an allowed height typically does not need one. That changes if you are going taller, moving the line, or the parcel has conditions on it.
Ask about your own fence line
Roughly how many feet, what is there now, how many gates, and which town. Photos help. Someone will call back to walk the line and put a real number on it.
