Property zoning determines permitted uses, density, setbacks, and development potential. Understanding your property's zoning classification is essential before purchasing or developing in Simi Valley.
City of Simi Valley Zoning Viewer
The City of Simi Valley maintains an online zoning map accessible through their planning department website. Enter your address or parcel number to view the exact zoning designation. The viewer displays the zone code (like R-1, C-2, or M-1), overlays affecting the property, and links to zoning ordinances defining permitted uses. This is free, immediate, and authoritative. Bookmark this tool for all property research—it's your primary zoning resource.
County Assessor Records and Parcel Information
The Ventura County Assessor's office maintains property records including zoning information, parcel dimensions, assessed values, and ownership history. Access assessor data online at the county assessor's website using your address. Parcel numbers from assessor records unlock detailed zoning documents. Cross-reference city zoning maps with county assessor records to ensure consistency and understand how county and city zoning layers interact.
Zoning Overlay Districts and Conditional Permissions
Base zoning (R-1, C-2) provides the foundation, but overlays modify permitted uses. Simi Valley uses overlays for historic districts, sensitive environmental areas, flood zones, and scenic corridors. A property might be zoned R-1 (residential) with a historic overlay restricting architectural modifications. Understanding overlays prevents costly surprise restrictions discovered during development. Planning department staff can explain specific overlay impacts on your property.
