Simi Valley is a large Ventura County suburban city with one of the most complex zoning structures in California - 185 distinct zone codes, the vast majority of which are specific plan variants organized under named master plan frameworks such as the Arroyo Simi Greenway (ASG), Brandeis Bardin Institute (BBI), Civic Center (CC), and dozens of others. This level of specificity reflects decades of tract-by-tract planned development across a city that grew rapidly through the 1970s and 1980s and is now largely built out. Most residential development was entitled and constructed as Specific Plan communities, meaning that the base residential estate, low, medium, moderate, and high density zones each appear in numerous named SP variants rather than as uniform citywide designations.
Among the most developable non-specific-plan zones, the Arroyo Simi Greenway framework governs significant acreage along the Arroyo Simi riparian corridor, including agricultural, open space, and residential-estate uses - the ASG-OS(A)(SP) designation alone covers 384 acres of open space with farm animal overlay. The Commercial Industrial (CI) and Commercial Industrial with Business Park overlay (CI(BP)) zones add modest commercial-industrial capacity, and the Civic Center (CC) zone at 69 acres anchors the city's government and civic campus. Several ASG residential zones - including ASG-RM(SP) at 144 acres - represent the most meaningful higher-density residential ground under a single named designation.
Building controls apply across all zones and include FAR, lot, multi, density, coverage, setbacks, lot width, pervious surface, and height requirements. For developers operating in Simi Valley, the practical implication of 185 zones is that almost every parcel has a unique development envelope - no assumptions should be made from zone code alone without reviewing the underlying specific plan document. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
Simi Valley zoning: frequently asked questions
What does it mean in practice that Simi Valley has 185 zone codes?
Almost all of Simi Valley's land is governed by named specific plans rather than standard base zoning, meaning each zone code corresponds to a specific geographic area with its own adopted development standards. A parcel coded ASG-RM(CZ)(SP) operates under the Arroyo Simi Greenway specific plan, medium density residential tier, with a conditional zoning overlay - which requires a separate specific plan document review to understand permitted uses, density limits, and any condition triggers. General zoning research is insufficient; specific plan documents must be obtained for each site.
How does the Arroyo Simi Greenway specific plan affect development along the riparian corridor?
The ASG framework governs land along the Arroyo Simi and includes open space, agricultural, and residential-estate designations that restrict intensity near the riparian habitat. The ASG-OS(A)(SP) designation at 384 acres combines open space with farm animal overlay, limiting development to agricultural and low-impact uses. Projects adjacent to the Arroyo are subject to CDFW streambed alteration agreements, Corps of Engineers Section 404 permitting, and the city's floodplain management requirements.
What commercial and industrial development options exist in Simi Valley?
Commercial capacity is spread across numerous small specific plan commercial nodes rather than consolidated in a few large zones. The Commercial Industrial (CI) zones, Civic Center (CC) at 69 acres, and various ASG commercial planned development zones are among the primary non-residential designations. Los Angeles Avenue and Tapo Canyon Road are the primary commercial corridors. Given the city's largely built-out character, most commercial opportunities involve repositioning or redevelopment of existing improved properties.
Are there multifamily housing opportunities in Simi Valley given the specific plan structure?
Multifamily development is concentrated in specific plan residential high and medium density tiers, with ASG-RM(SP) at 144 acres being one of the largest single higher-density residential zones. California's housing element law, density bonus, and RHNA obligations have increased pressure on Simi Valley to identify and permit additional housing sites. The city's housing element identifies opportunity sites for rezoning; projects on those sites may qualify for streamlined approval under SB 35 or other state housing statutes.
What is the Conditional Zoning (CZ) overlay and how does it affect entitlement?
Several zones in Simi Valley carry a (CZ) suffix, such as ASG-RH(CZ)(SP) and ASG-RM(CZ)(SP), which indicates a conditional zoning overlay that ties the permitted use or density to specific conditions that must be satisfied - often infrastructure completion, development agreement milestones, or environmental clearances. Projects on CZ parcels may not proceed at the indicated density until all conditions are met. Buyers should confirm whether conditions have been satisfied and what obligations remain before underwriting CZ sites.
