Fair Oaks & Unincorporated Sacramento County Fence Rules

If you live in Fair Oaks, your fence is not ruled by the City of Sacramento. Fair Oaks is unincorporated — and so is Carmichael — which means your fence follows the Sacramento County Zoning Code, not a city fence ordinance. That distinction matters, because the County’s numbers are different from the City’s, especially in the front yard.

This guide explains the County’s own fence standards for single-family homes in unincorporated areas like Fair Oaks and Carmichael, as the County publishes them today. It is general information only, not legal advice. Every figure below comes from the County’s official sources, cited by name and linked, so you can check them yourself.

With more than 30 years of hands-on fence experience, here is how we walk Fair Oaks homeowners through it.

First, confirm you are really in the County’s area

Fair Oaks and Carmichael have Sacramento mailing addresses, but neither is inside the City of Sacramento. If your home is in unincorporated Sacramento County, the rules in this article are the starting point. If you are inside a city — Sacramento, Citrus Heights, Folsom, or Roseville — that city’s rules apply instead, and we have separate guides for those cities on our blog.

The County’s fence standards live in the Sacramento County Zoning Code, Chapter 5, Section 5.2.5 — Development Standards for Walls and Fences.

Back and interior side yards: the 7-foot ceiling

For the fence most Fair Oaks homeowners build — the backyard privacy fence on a rear or interior side property line — the County standard in Section 5.2.5.C.4 is clear:

• Interior-yard fences shall not exceed 7 feet in height.
• An interior fence may be located on a retaining wall not to exceed 4 feet in height.
• Height on an interior line is measured from the highest elevation at the interior property line or at the finished grade of the rear or side yard, whichever is higher.

In plain words: the familiar 6-foot redwood privacy fence is comfortably inside the County limit, and even a 7-foot fence is allowed on an interior line. Two cautions still apply:

• A taller fence is a bigger sail in winter storms. Height compliance gets a fence allowed; post depth and concrete decide whether it stays straight (see our build standard below).
• Your HOA, if you have one, can set a lower maximum or require a specific style. County compliance does not override a private HOA agreement.

What about going over 7 feet on an interior line? Section 5.2.5.C.6 allows fences over 7 feet when they are set back 3 feet from an interior property line after first securing an approved building permit, and fences over 7 feet may also be permitted on interior property lines with a Special Development Permit approved by the Zoning Administrator. The County’s Chapter 7 definitions make the same point another way: a fence is defined as 18 inches to 7 feet high, and a barrier over 7 feet is considered a structure.

Street side yards on corner lots: also 7 feet — with a front-yard twist

Section 5.2.5.C.3 caps fences in a side street yard at 7 feet, and says a retaining-wall-and-fence combination over 7 feet may be permitted with a Minor Special Development Permit.

Corner lots get a specific rule in Section 5.2.5.C.5: regardless of which frontage determines the front lot line, for measuring fence height the frontage with the primary entrance to the main dwelling is considered the front yard, and the other frontage is considered the side street yard. If a corner home has established primary entrances on both frontages, both frontages are treated as front yards — and the stricter front-yard limits below then apply on both streets. Corner lots are the most common place Fair Oaks fences go wrong, so confirm which frontage the County treats as your front before you set posts.

Front yards: the County’s material-by-material limits

This is where unincorporated County rules differ most from what many homeowners expect. In the required front-yard setback area, Section 5.2.5.C.1 (for all zones except Agricultural and Agricultural-Residential) limits fences to:

• Solid walls or fences: not exceeding 3 feet
• Semi-open fencing, such as picket fencing: not exceeding 4 feet
• Open fencing of chain link or similar woven wire, or expanded metal: not exceeding 4 feet
• Open fencing of wrought iron or similar material: not exceeding 7 feet
• Open fencing (other than chain link) over a solid fence: solid portion not exceeding 3 feet, overall height not exceeding 7 feet

The County defines an “open” fence in Chapter 7 as a barrier that permits direct vision through at least 75 percent of any one-square-foot segment when viewed straight on — that is why wrought-iron-style fencing can go taller in front while a solid wood fence cannot.

One more front-yard option: fences exceeding the first three limits above, up to 7 feet, may be allowed with a Minor Special Development Permit.

If your lot is in an Agricultural or Agricultural-Residential zone, Section 5.2.5.C.2 is simpler: the front-yard maximum is 7 feet for open or solid fencing. Most Fair Oaks homes are not in those zones, so do not assume this applies to you — confirm your zoning with the County.

In plain words: a solid 6-foot privacy fence across a Fair Oaks front yard is not a compliant plan. Design a front fence low and solid at 3 feet, semi-open at 4 feet, or open wrought-iron style if you need height — or step the tall privacy fence back behind the front setback line, where the interior or side-street rules apply.

How the County measures fence height

Section 5.2.5.B sets the measuring rule, and on sloped Fair Oaks lots it can change the answer:

• For fences within 5 feet of a public right-of-way (or a right-of-way with a public utilities and public facilities easement), height is measured from the grade of the right-of-way.
• Beyond 5 feet, height is measured from the highest elevation of the ground on either side of the fence.

That “highest side” rule matters when you and your neighbor are at different grades: measure from the higher ground, not the lower, or a fence that looks like 6 feet from your yard can measure over the limit from the other side.

At drives and street intersections, Section 5.2.5.A.1 also requires fences, walls, and landscape screening to meet the visibility requirements of the Sacramento County Improvement Standards — drivers must be able to see around your corner fence.

Materials, maintenance, and what is prohibited in front

Section 5.2.5.A allows fences built of permanent materials such as wood, chain link, stone, rock, concrete block, masonry brick, and decorative wrought iron, or another material approved by the Planning Director.

For fences in the front yard, street side yard, and fences abutting an alley or other public right-of-way, the County prohibits materials including cast-off or secondhand items not originally intended for fencing, and thin plywood (less than five-eighths inch), particle board, paper, plastic tarp, cloth, and similar materials.

Barbed wire and concertina wire require a Minor Special Development Permit, except in the situations the Code lists for agricultural and industrial zones — and barbed wire is permitted in the AR-2, AR-5, and AR-10 zones when used for keeping animals.

And every fence carries a maintenance duty under Section 5.2.5.A.9: all fences shall be properly maintained so as not to create a hazard, public nuisance, or blight. A leaning, broken fence is not just ugly in the County’s eyes — it is a code problem.

Do you need a building permit for a fence in Fair Oaks?

For most backyard fences, no — but zoning approval is a separate question from a building permit.

Sacramento County’s Building Permits & Inspection Division publishes GI-21, Residential Work Exempt from Permit, which lists “fences not over 7 feet high” as work that does not require a building permit, and refers readers to the County’s Masonry Wall, Fence and Retaining Wall guideline for detailed permit criteria. The same handout lists retaining walls not over 4 feet high — measured from the bottom of the footing to the top of the wall — as exempt unless the wall supports a surcharge.

That means:

1. A fence 7 feet or under that meets the zoning heights above is generally building-permit exempt in unincorporated County.
2. A fence over 7 feet, a tall masonry wall, or a fence on a tall retaining wall is a different project — confirm permit and any Special Development Permit requirements before you build.
3. A fence that is also a pool barrier has separate safety requirements: Section 5.2.5.A.2 requires perimeter fences around private pools subject to the California Building Code provisions it cites. Do not assume a standard backyard fence automatically satisfies pool-barrier rules.

When in doubt, the two County stops are Planning & Environmental Review at (916) 874-6141 or sacplan@saccounty.gov for zoning and height, and the Building Permits & Inspection Division general information line at (916) 875-5296 for permit questions.

How we build a Fair Oaks fence that fits the rules — and lasts

Height compliance gets a fence allowed. Build quality decides whether it is still straight in ten years, especially in Sacramento-area clay soil that swells when wet and shrinks when dry. On every fence we build in Fair Oaks and Carmichael:

• Posts are set 2 to 3 feet deep in concrete — toward the deeper end for taller fences and heavy gates.
• Every post is wrapped in a waterproof membrane below ground, where soil moisture works against the wood.
• The frame is pressure-treated posts and rails, with redwood pickets for the face you see every day.
• Rails and pickets are fastened with Simpson steel connectors and screws, never nails that work loose as wood moves through hot summers and wet winters.

See our Fencing page for the full build standard. Every fence we build carries a 12-month workmanship warranty on the work we performed.

Frequently asked questions

How tall can a backyard fence be in Fair Oaks?
On an interior property line in unincorporated Sacramento County, fences shall not exceed 7 feet under Zoning Code Section 5.2.5.C.4, and they may sit on a retaining wall up to 4 feet high. Most homeowners build 6 feet for privacy, which is well inside the limit.

How tall can a front-yard fence be in Fair Oaks?
It depends on the material. In the front-yard setback, solid fences are limited to 3 feet, semi-open picket and open chain-link/woven-wire or expanded-metal fencing to 4 feet, and open wrought-iron-style fencing to 7 feet. Open fencing over a solid base can reach 7 feet overall if the solid portion stays at 3 feet or less.

Do I need a permit to build a fence in unincorporated Sacramento County?
The County’s GI-21 handout lists fences not over 7 feet high as exempt from a building permit. Zoning height limits still apply, and fences over 7 feet, masonry walls, retaining-wall combinations, and pool barriers can trigger permit or Special Development Permit requirements — confirm with Planning at (916) 874-6141 and Building at (916) 875-5296.

My lot is on a corner in Carmichael. Which side is my front yard?
For fence-height measurement, the County treats the frontage with the primary entrance to the main dwelling as the front yard and the other frontage as the side street yard. If your home has primary entrances on both frontages, both are treated as front yards, so the front-yard limits apply on both streets.
