What should developers know about Fillmore zoning?
Fillmore is a small Ventura County city in the Santa Clara River Valley, and its 16 zoning districts combine a conventional residential ladder with several specific-plan areas guiding its growth. The dominant residential district is Residential Low (R-L) at about 432 acres, followed by Residential Medium (R-M, roughly 172 acres), with smaller Residential Rural (R-R, about 116 acres), Residential High (R-H), and Residential Medium High (R-MH) categories rounding out the density tiers. Two large specific plans shape new development: the Heritage Valley Parks Specific Plan (HVPSP, about 275 acres) and the North Fillmore Specific Plan (NFSP, roughly 92 acres), both of which carry their own master-planned standards rather than relying on the base zoning.
Commercial and employment land is organized by format. The city has two Business Park districts (BP-1 and BP-2, together roughly 96 acres), a Commercial Highway district (CH, about 91 acres) along the travel corridor, a Central Business District (CBD, about 37 acres) for the downtown core, plus Commercial Office (CO) and Commercial Neighborhood (CN). Industrial use is limited to a single Industrial district (M-I, about 40 acres). The largest non-residential categories are Open Space (OS, about 235 acres) and Public Facilities (PF, about 178 acres), reflecting the valley's open setting and civic land. For developers, the key distinction is whether a parcel falls under a base zone or one of the two specific plans, since the latter will dictate permitted uses and standards. With FAR, lot, density, coverage, pervious, lot-width, setback, and height controls all in play, that determination drives the feasibility analysis.

Fillmore zoning: frequently asked questions
What are the specific plans in Fillmore, and why do they matter?
Fillmore has two large specific-plan areas: the Heritage Valley Parks Specific Plan (about 275 acres) and the North Fillmore Specific Plan (about 92 acres). A specific plan replaces the base zoning with its own tailored land-use and development standards for that area. If a parcel falls inside one of these plans, you must work from the plan's rules rather than the conventional district standards, so identifying the governing document is the first step in due diligence.
Where is higher-density housing allowed in Fillmore?
Higher-density housing is directed to the Residential High (R-H) and Residential Medium High (R-MH) districts, with Residential Medium (R-M, about 172 acres) carrying mid-density product. The bulk of the residential land, however, is Residential Low (R-L) at roughly 432 acres. The two specific plans may also accommodate multifamily under their own standards, so check both the base zones and the plan areas when sizing a housing project.
What employment and commercial land does Fillmore offer?
Fillmore organizes its commercial land by format: two Business Park districts (BP-1 and BP-2, together about 96 acres) for employment uses, Commercial Highway (CH, about 91 acres) along the corridor, a Central Business District (CBD, about 37 acres) downtown, plus Commercial Office and Commercial Neighborhood. Industrial activity is confined to a single Industrial (M-I) district of about 40 acres. Match your use to the format - business park, highway, downtown, or neighborhood - early in your analysis.
How much open space and rural land is in Fillmore?
Open Space (OS) is one of the larger districts at about 235 acres, and Residential Rural (R-R) adds roughly 116 acres of low-intensity, large-lot land. Combined with Public Facilities (PF, about 178 acres), a substantial share of the city's land base is in low-density or non-private categories. This reflects Fillmore's river-valley setting and should be netted out when estimating developable supply.
Can ADUs help add units in Fillmore's low-density neighborhoods?
Yes. California's statewide accessory dwelling unit laws apply in Fillmore, and given how much of the city is zoned Residential Low and Residential Rural, ADUs are a realistic way to add units on existing single-family lots. Local rules on size, setbacks, and parking still apply, and parcels within a specific plan may have additional or different provisions. Verify the applicable standards with the city before designing.
