What should developers know about Auburn zoning?
Auburn, the Placer County seat in the Sierra foothills, runs a detailed 38-district code that mixes foothill residential, a historic commercial core, and a notable habit of combining districts on a single map symbol. The largest residential classification is Single Family Residential R1-10 at roughly 986 acres, and a broad Agricultural Residential family (AR, AR-2, AR-5, AR-20) preserves the low-density, rural-edge character of the surrounding foothills. The single biggest district overall is Open Space and Conservation (OSC) at about 773 acres - a direct reflection of Auburn's canyon-and-ridge setting and the priority placed on protecting it.
A defining feature of Auburn's zoning is its combining districts: classifications like C-1/R-2, C-1/R-3, M-1/C-1, OB/R-3, and C-2/OSC blend commercial, residential, industrial, and open-space allowances on the same ground, giving developers flexible but layered standards to navigate. The commercial hierarchy runs from Neighborhood Commercial (C-1) through the Central Business District (C-2, about 134 acres) - Auburn's historic Old Town and downtown core - up to Regional Commercial (C-3, about 152 acres). Industrial uses sit in the Industrial Park (M-1), Industrial (M-2, about 118 acres), and the Airport Industrial Design Control (AI-DC) district near the airport. The takeaway: read the full combined designation on any parcel, because a single site may carry both a commercial and a residential or open-space layer. Form is governed by FAR, density, coverage, lot-width, height, and full setback controls.

Auburn zoning: frequently asked questions
What are Auburn's combining districts and why do they matter?
Auburn frequently combines two or more designations on a single parcel - examples include C-1/R-2, C-1/R-3, M-1/C-1, OB/R-3, and C-2/OSC. These combining districts blend commercial, residential, industrial, or open-space allowances, so the rules on one site can come from multiple base classifications at once. Always read the full combined designation, since it determines what mix of uses and standards actually applies.
Where is Auburn's downtown and commercial development focused?
The Central Business District (C-2) covers about 134 acres and anchors Auburn's historic Old Town and downtown core, with Neighborhood Commercial (C-1) serving smaller nodes and Regional Commercial (C-3) at roughly 152 acres handling larger-format retail. Downtown is the most character-sensitive area, suited to infill and reuse, while C-3 along the highway corridors accommodates regional retail.
How does Auburn's foothill and open-space character constrain development?
Open Space and Conservation (OSC) is the city's single largest district at about 773 acres, and several parcels carry OSC as a combining layer over commercial or residential designations. Combined with the broad Agricultural Residential districts, this reflects a strong priority on protecting Auburn's canyons and ridges. Expect terrain, conservation, and design constraints on foothill sites, and confirm whether an OSC overlay limits buildable area.
What residential development does Auburn's zoning support?
Single-family ground dominates, led by R1-10 at roughly 986 acres and the standard R-1 district, with a tiered Agricultural Residential family (AR, AR-2, AR-5, AR-20) covering lower-density foothill land. Higher-density options appear largely through combining districts such as C-1/R-3 and OB/R-3 that pair medium-density multifamily with commercial or office uses. Pure multifamily ground is comparatively limited, so density plays often run through these combined designations.
Is there industrial or airport-related land available in Auburn?
Yes. Industrial uses are served by the Industrial Park (M-1) and Industrial (M-2, about 118 acres) districts, plus Light Manufacturing (M-L). Notably, the Airport Industrial Design Control (AI-DC) district covers roughly 293 acres near the airport, making it the primary location for aviation-related and design-controlled industrial development. Users with airport-adjacent needs should focus on the AI-DC district.
