What should developers know about Danville zoning?
Danville's land use is overwhelmingly shaped by a single tool: the Planned Unit District (P-1), which covers roughly 3,770 acres - dwarfing every other district in town and effectively making master-planned, site-specific approvals the default way development happens here. Several variants extend it, including P-1 combined with general agricultural (P-1(A-2)), multifamily (P-1(M-13), P-1(M-8)), and limited office (P-1(O-1)) standards. For a developer, that concentration means the entitlement question in Danville is usually not what does the base zone allow, but what does the governing planned-development approval permit for this specific parcel.
Beyond the P-1 framework, Danville retains a notably rural and agricultural edge for a Bay Area suburb: General Agricultural (A-2) covers about 399 acres and Agricultural Preserve (A-4) another 341 acres, signaling large-lot, low-intensity land at the city's fringe. The multifamily inventory is organized as a numbered density ladder - M-8, M-13, M-20, M-25, M-30, and M-35 - with M-35 (about 51 acres) and M-13 (about 47 acres) the largest, giving the clearest by-right path to apartment-scale housing. The real activity center is the Downtown Business District, fragmented into more than a dozen sub-districts (DBD1 through DBD13) that finely separate Old Town retail, mixed use, office, and high-density residential blocks - a granular code that rewards close reading before any downtown acquisition. The presence of full building-control standards, including FAR, density, coverage, and setback controls, means form is tightly regulated across districts.

Danville zoning: frequently asked questions
Why is so much of Danville zoned Planned Unit District (P-1)?
P-1 spans about 3,770 acres, more than any other district by a wide margin, because Danville has historically entitled large residential and mixed projects through master-planned approvals rather than uniform base zoning. The consequence for buyers is that the controlling document is the specific P-1 development plan for the parcel - allowed uses, density, and design are set there, so generic zone lookups will not tell you what you can build.
How is Danville's downtown zoned for development?
The Downtown Business District is split into more than a dozen sub-districts (DBD1 through DBD13) that distinguish Old Town retail transition, Old Town retail, mixed use, residential-serving commercial, professional office, and high-density multifamily residential blocks. Districts like DBD12 and DBD13 carry high-density residential designations, making them the most promising downtown targets for housing or mixed-use infill - but each sub-district has its own use and form rules.
Which districts support multifamily housing in Danville?
Danville uses a numbered multifamily ladder - M-8, M-13, M-20, M-25, M-30, and M-35 - where the trailing number signals increasing intensity, with M-35 (about 51 acres) and M-13 (about 47 acres) the largest. Several of these also appear in combined planned-unit form (for example P-1(M-13) and P-1(M-8)), and the downtown DBD sub-districts add further high-density residential capacity.
What kind of agricultural land does Danville still have?
The city keeps two meaningful agricultural categories: General Agricultural (A-2) at about 399 acres and Agricultural Preserve (A-4) at roughly 341 acres, the latter typically tied to Williamson Act-style contracts that restrict conversion. These large-lot designations on the city edge mean any development push there confronts both low base density and potential contract or open-space constraints.
How tightly is building form regulated in Danville?
Danville applies a full slate of building controls - FAR, lot, density, coverage, pervious surface, lot width, and front, side, and rear setback controls, plus building height - across its districts. That comprehensive control set, combined with the dominance of planned-development approvals, means design parameters are highly site-specific and should be confirmed against both the zone and any applicable P-1 plan early in feasibility.
