Do you need a building permit in Sacramento County, California?

Yes. Unincorporated Sacramento County requires a permit before starting construction, alteration, repair, demolition, an occupancy change, or regulated electrical, gas, mechanical, or plumbing work1. The county's own FAQ directs applicants to apply to the building official and obtain the required permit before work begins10. Work exempted under California Building Code or California Residential Code Section 105.2 may not need a permit, so confirm the scope with Building Permits & Inspection before construction111. Permit applications submitted on or after January 1, 2026 must comply with the 2025 California Building Standards Code1213.

Who is the Sacramento County building department, and how do you reach them?

The Sacramento County Building Permits & Inspection Division handles permit applications, plan review, and inspections for unincorporated Sacramento County11. The Building Assistance Center is at 9800 Goethe Road, Sacramento, CA 95827, and its public phone number is 916-875-529611. The division accepts electronic plan submittals and reviews through the county's online permitting process1411. Before pouring concrete or covering completed work, arrange the required inspection; Sacramento County will not perform an inspection without a valid issued building permit at the project site15. For a residential project, the inspector-signed final job card serves as the certificate of occupancy16.

Does Sacramento County have zoning?

Yes. The Planning & Environmental Review Division administers the General Plan and Zoning Ordinance and manages development in unincorporated Sacramento County217. If a parcel is inside an incorporated city, that city's planning department administers the applicable land-use rules instead3. In applicable low-density residential districts, the standard front setback is 20 feet without a projecting unenclosed porch feature and 24 feet with one; the interior side setback is 5 feet for a one- or two-story building18. Maximum height in those districts is 30 feet for one- or two-story construction and 40 feet for three-story construction19. Special Planning Areas, Specific Plans, Planned Unit Developments, and other parcel-specific standards can change the result, so verify the zoning and overlays with Planning before designing the site320.

How do septic permits work in Sacramento County?

The Environmental Management Department's Liquid Waste Program oversees septic systems, onsite wastewater treatment systems, and wastewater holding tanks throughout Sacramento County421. Site geology affects the applicable requirements, so have EMD evaluate the parcel before assuming a conventional drain field will work2122. Only about 9% of Sacramento County soils are rated without severe limitations for a conventional septic drain field23. If public sewer is available within 200 feet of the property line, connection may be required24. A composting toilet is not a way around wastewater approval: county rules require permission and a permit from the building authority, an EMD operating permit, and either a compliant onsite wastewater system or a public-sewer connection25. A new well also requires an EMD permit unless county code specifically exempts it926.

Can you live in an RV or tiny home on your land in Sacramento County?

An RV cannot serve as a dwelling unit in unincorporated Sacramento County unless it is parked at a permitted mobile home park7. That rule addresses living in the RV, not ordinary parking or storage7. A movable or undersized tiny home also cannot serve as a dwelling unless it is placed on a permanent foundation and complies with residential building codes8. Manufactured homes are different: Sacramento County allows them in most cases as a primary residence or accessory dwelling unit when they meet the county zoning standards27. For an already-developed qualifying residential property, a code-compliant accessory dwelling unit may offer another route to living space; a new detached ADU can be up to 1,200 square feet, while a junior ADU can be up to 500 square feet, with an additional 150 square feet allowed for ingress and egress under the county table28.

How do you build a home in Sacramento County?

  1. Confirm the parcel is unincorporated Sacramento County, not inside a city, since city planning departments set their own rules3.
  2. Contact the Planning & Environmental Review Division to confirm the zoning district and any Special Planning Area or Combining Zone standards that apply to the lot20.
  3. Arrange a septic or sewer evaluation with the EMD Liquid Waste Program, and a well permit if the property will use groundwater2226.
  4. If the driveway crosses a county road right-of-way, apply for an encroachment permit through County Engineering's Site Improvement & Permit Section before starting site work29.
  5. Submit building plans through the county's online Accela portal to the Building Permits & Inspection Division14.
  6. Schedule inspections before covering any completed work, and keep the issued permit and inspection card on site for every visit15.
  7. Get final sign-off on the job card, which serves as the certificate of occupancy for a residential project16.

What should you check before buying land in Sacramento County?

Confirm whether the parcel is in unincorporated Sacramento County or inside a city before relying on county rules3. Ask the Liquid Waste Program about the site's soil and septic history because only about 9% of county soils are rated without severe limitations for a conventional drain field2322. Nearly 90% of Sacramento County land has a slope of 15% or less, but a gentle parcel can still have difficult soils30. Confirm public-sewer availability because connection may be required when sewer is within 200 feet of the property line24. Verify legal road access and ask County Engineering whether a new or repaired driveway in the public right-of-way needs an encroachment permit29. For carrying-cost context, the median annual property-tax bill is about $3,768 and the effective property-tax rate is about 0.8%3132.

Watch-outs

  • A composting toilet still requires building-authority approval, a building permit, an EMD operating permit, and either a compliant onsite wastewater system or a public-sewer connection25.
  • The setback and height figures above apply only to specified low-density residential districts; confirm the parcel's zoning and any special local standards before finalizing a site plan181920.

California rules that apply here

  • Owner-builder exemptionAvailable (with conditions)

    Exemption from California contractor-licensing chapter for an owner-builder who builds or improves a structure on the owner’s property; this does not itself establish exemption from local building permits, inspections, or other code requirements.

    • For work personally performed by the owner or performed by the owner’s employees, none of the improvements may be intended or offered for sale, and employee compensation must be wages as their sole compensation.
    • For work directly contracted to licensed trade contractors, the owner must directly contract with licensees duly licensed for the respective trades.
    • For single-family residential structures under the licensed-contractor arrangement, no more than four structures may be intended or offered for sale in a calendar year; this limitation does not apply if the owner contracts with a general contractor for construction.
    • For a homeowner improving a principal residence or its appurtenances, the work must be performed before sale, the homeowner must have actually resided in the residence for the 12 months before completion, and the homeowner must not have used this exemption on more than two structures more than once during any three-year period.
    • A nonprofit corporation may qualify when assisting an owner-builder participating in a mutual self-help housing program.

Water rights & wells in Sacramento County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from California’s water agency.

Actively managed

This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.

Household wellPermit required — restricted

California requires no STATE permit for a domestic well — wells are permitted by the county — but under SGMA a Groundwater Sustainability Agency can meter or restrict new wells in medium/high-priority and critically overdrafted basins, and Executive Order N-7-22 requires counties in those basins to get GSA verification that a new well is consistent with the Groundwater Sustainability Plan before permitting.

Limit: 2 acre-feet/year de minimis under SGMA (Water Code §10721(e)) — largely exempt from GSA metering/fees
