Sacramento County Planning and Development: Zoning, Permits, and Land Use

Sacramento County's Planning and Development Department administers the land use regulations, zoning designations, and permit processes that govern how roughly 575,000 residents in unincorporated areas can build, modify, or use property. This page explains the structure of county zoning authority, how the permitting process operates from application to inspection, common project types that require county review, and the boundaries that separate county jurisdiction from those of Sacramento's incorporated cities. Property owners, developers, and residents making decisions about land use in the Sacramento region need to understand which governmental body holds authority over their specific parcel.

Definition and scope

The Sacramento County Department of Planning and Development (Sacramento County Planning and Development) is the primary agency responsible for implementing the Sacramento County General Plan, administering the Sacramento County Zoning Code, and processing building permits for land within unincorporated Sacramento County.

Unincorporated Sacramento County refers to land that lies within county boundaries but outside the limits of any incorporated city. The 9 incorporated cities in Sacramento County — including Sacramento, Elk Grove, Folsom, Citrus Heights, Rancho Cordova, and others — each operate independent planning departments under their own municipal codes. The county department's authority does not apply to parcels within those city limits. For city-specific planning matters, residents must contact the respective municipal agency rather than the county department.

The department's core responsibilities fall into three functional areas:

  1. Long-range planning — updating and implementing the General Plan, area-specific plans, and environmental review under the California Environmental Quality Act (CEQA)
  2. Current planning — processing discretionary applications such as use permits, variances, subdivision maps, and rezone requests
  3. Building and safety — issuing ministerial building permits, conducting inspections, and enforcing construction codes

Sacramento County adopted its current General Plan in 2011 (Sacramento County General Plan 2030), with subsequent amendments governing growth, housing density, agricultural preservation, and environmental protection across the unincorporated territory.

How it works

Zoning designations are the foundational regulatory tool. Every parcel in unincorporated Sacramento County carries a zoning classification that specifies permitted uses, density limits, setback requirements, height maximums, and lot coverage standards. The Sacramento County Zoning Code (Title 22, Sacramento County Code) organizes these classifications into broad categories including residential, commercial, industrial, agricultural, and special-purpose zones.

Two types of land use approvals exist at the county level:

The typical ministerial permit process moves through 4 stages: application submission, plan check review, permit issuance, and field inspections at defined construction milestones. Complex discretionary applications add environmental review, public comment periods of a minimum 20 days for most CEQA notices, and one or more public hearings.

The Sacramento County Board of Supervisors serves as the final decision-making body for major land use actions, including General Plan amendments and rezonings. The Planning Commission hears most conditional use permits and subdivision maps as the primary decision-maker or in an advisory capacity, depending on the application type.

Common scenarios

Property owners and developers most frequently interact with the department in the following situations:

  1. New residential construction — Single-family homes on unincorporated parcels require a building permit, site plan review for compliance with setbacks and lot coverage, and inspections at foundation, framing, rough mechanical/electrical/plumbing, and final stages.

  2. Accessory dwelling units (ADUs) — California state law, particularly AB 68 (2019) and subsequent amendments, streamlined ADU permitting statewide. Sacramento County updated its local ADU ordinance to comply, reducing setback requirements and eliminating owner-occupancy mandates for most ADU types.

  3. Agricultural land use changes — Unincorporated Sacramento County contains significant agricultural land designated under Williamson Act contracts (California Land Conservation Act, Government Code §51200). Converting agricultural parcels to other uses requires cancellation of existing contracts and is subject to CEQA review.

  4. Commercial development — New retail, office, or industrial projects typically require a discretionary use permit if the proposed use is not outright permitted in the base zone, plus environmental review, traffic studies, and drainage analysis.

  5. Variances — When site-specific conditions prevent compliance with standard zoning requirements (unusual lot shape, topography), a property owner may apply for a variance. Granting requires a finding of hardship that is not self-created and does not constitute a grant of special privilege.

Decision boundaries

Understanding when county jurisdiction applies — versus city, state, or federal authority — prevents costly errors in project planning.

County vs. city jurisdiction: The critical threshold is whether a parcel is inside or outside an incorporated city's limits. Parcels in unincorporated Sacramento County fall under county zoning and permit authority. Parcels in Sacramento city, Elk Grove, Folsom, or any other incorporated municipality are subject to that city's municipal code, not the county's. The Sacramento County Assessor's parcel search tool can confirm jurisdictional status by address.

County vs. state authority: California state law sets a floor for certain land use decisions — ADU permitting, housing element compliance, and environmental review under CEQA. Where state law preempts local standards, county regulations must yield. The California Department of Housing and Community Development (HCD) audits county housing elements and can refer non-compliant jurisdictions to the California Attorney General.

County vs. federal authority: Federal lands within Sacramento County — managed by the U.S. Army Corps of Engineers, the Bureau of Reclamation, or other agencies — are not subject to county zoning. Development near waterways or wetlands may also require a Section 404 permit from the U.S. Army Corps of Engineers independent of any county approval.

Ministerial vs. discretionary: This distinction determines both the timeline and the level of public input.
