Fairfield is a mid-size Solano County city that doubles as a regional commercial and industrial hub between the Bay Area and Sacramento, and its 35 zoning districts span an unusually broad range. The largest mapped categories are Public Facility (PF, roughly 6,570 acres), Open Space Conservation (OSC, about 3,880 acres), and Recreation (REC, about 1,522 acres), which together reserve a large share of land for civic, conservation, and recreation uses. On the private side, residential land is layered across multiple density tiers, with Residential Low Medium Density 6 (RLM-6) the standout at roughly 3,044 acres, followed by RL-8 (about 1,519 acres), RLM-5, RLM (Low Medium Density), and a dedicated Residential High Density (RH, about 537 acres) for apartment-scale product.
Fairfield's economic base shows up clearly in its industrial inventory: Limited Industrial (IL, about 1,766 acres) is one of the city's largest single districts, joined by General Industrial (IG, roughly 470 acres) and an Industrial and Business Park (IBP, about 361 acres). Commercial land is equally varied, from Regional Commercial (CR, roughly 677 acres) and Service Commercial (CS) down to Neighborhood Commercial (CN) and a dedicated Office Commercial (CO). The city also runs a coordinated downtown program through its Heart of Fairfield districts - Downtown (HD), Downtown Core (HDC), Mixed Use Office (HO), Residential (HR), and a Transit Oriented Development (HTD) category - signaling a deliberate push toward denser, transit-supported infill in the core. Agricultural reserves (AG-20, AG-40, AG-80, the last about 986 acres) hold the urban edge. With the full set of FAR, lot, density, coverage, pervious, lot-width, setback, and height controls in force, matching a project to the right tier among these many districts is the first underwriting step.

Fairfield zoning: frequently asked questions
What are the Heart of Fairfield districts for?
The Heart of Fairfield districts are Fairfield's downtown revitalization framework, covering Downtown (HD), Downtown Core (HDC), Mixed Use Office (HO), Residential (HR), and a Transit Oriented Development category (HTD). They are designed to support denser, mixed-use, and transit-supported development in the city center rather than the lower-intensity formats found elsewhere. If you are pursuing infill or mixed-use in the core, these are the districts whose standards will govern your project.
Where is high-density and multifamily housing concentrated in Fairfield?
The Residential High Density (RH) district, at roughly 537 acres, is the primary home for apartment-scale multifamily product. Beyond it, the Heart of Fairfield Residential (HR) and Transit Oriented Development (HTD) districts support denser housing in the downtown context. The various RLM and RL tiers handle lower-medium and low-density housing, so reading the specific density suffix is essential when sizing a residential deal.
How strong is Fairfield's industrial market based on its zoning?
Industrial zoning is a defining feature of Fairfield. Limited Industrial (IL) alone covers roughly 1,766 acres, one of the largest districts in the city, and it is reinforced by General Industrial (IG, about 470 acres) and the Industrial and Business Park (IBP, about 361 acres). That scale of mapped industrial land points to a substantial logistics, manufacturing, and business-park base for which the city has reserved significant capacity.
What do the AG districts mean for development at the city edge?
Fairfield maintains three agricultural districts - AG-20, AG-40, and AG-80 - with AG-80 the largest at about 986 acres. The numbers reflect large minimum parcel sizes intended to keep this land in agriculture and hold the urban growth boundary. Parcels in these districts are generally not available for urban-intensity development without a rezoning and likely Local Agency Formation Commission action, so treat them as long-horizon.
Why does Public Facility (PF) zoning cover so much land in Fairfield?
Public Facility is the single largest district in Fairfield at roughly 6,570 acres, which reflects civic, institutional, and infrastructure holdings as well as land tied to nearby government and military-adjacent uses. Combined with Open Space Conservation (about 3,880 acres) and Recreation (about 1,522 acres), a large fraction of the city's land base is in non-private categories. Investors should subtract that footprint when estimating the genuinely developable inventory.
