What should developers know about Willows zoning?
Willows, the county seat of Glenn County, has 16 zoning districts that reflect a mid-sized agricultural service city balancing residential neighborhoods, a historic downtown core, light and heavy manufacturing, and highway-oriented commercial uses. Single Family Residential (R-1) at approximately 529 acres is the city's dominant residential district, with Single Family Housing and Planned Development (R-1/PD) adding 120 acres where new subdivisions are processed under master-planned frameworks. High Density Residential (R-3) at 38 acres and Residential Professional (RP) at 67 acres provide the primary platforms for multifamily housing and mixed professional-office/residential uses.
The manufacturing sector is well-represented: Light Manufacturing (ML) at 181 acres and Heavy Manufacturing (MH) at 108 acres together account for nearly 290 acres of industrial-designated land, a substantial employment base for a small city. On the commercial side, General Commercial (GC) and Highway Commercial (CH) each contribute roughly 80 acres, while the Central Commercial (CC) district at 54 acres anchors the downtown retail core. Notably, a cluster of combination districts - CG/ML, CG/ML/PD, and CG/PD - totaling about 232 acres signals locations where commercial and light industrial uses are blended, offering flexibility for hybrid projects. Public Facilities and Services (PF) accounts for another 200 acres.
Building controls span the full regulatory range - FAR, density, coverage, pervious, lot width, and all setbacks - and the presence of planned development overlays in both residential and commercial categories indicates that Willows actively uses PD tools to manage growth phasing and design quality. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.

Willows zoning: frequently asked questions
What are the combination commercial-industrial districts (CG/ML, CG/ML/PD, CG/PD) and how do they affect development options?
These hybrid districts permit general commercial and light manufacturing uses on the same parcels, with the PD suffix indicating that some sites are additionally subject to planned development controls. Together they total about 232 acres and are particularly suited for flex-industrial, showroom-warehouse, or light manufacturing with ancillary retail. Projects on these parcels benefit from use flexibility but should confirm whether an adopted PD plan governs the site's specific standards.
Where can multifamily housing be developed in Willows?
R-3 High Density Residential (38 acres) is the primary multifamily zone, while Residential Professional (RP, 67 acres) allows a mix of low-scale residential and professional office uses. The R-1/PD parcels may also include multifamily components depending on their governing planned development. California ADU law and density bonus provisions expand housing capacity further on R-1 and R-3 lots citywide.
How does Willows' Central Commercial (CC) district compare to its highway commercial zones?
CC (54 acres) covers the historic downtown and is designed for walkable, pedestrian-oriented retail, dining, and services. Highway Commercial (CH) at 80 acres targets auto-oriented uses along approach corridors and accommodates drive-throughs, motels, and service stations. General Commercial (GC) at 81 acres bridges the two, supporting community-scale retail that does not require a downtown setting. Developers should align their program type with the appropriate commercial tier.
Is there agricultural-residential land within Willows' city limits?
The R-1/A Single Family Residential Housing and Agriculture district covers about 15 acres and allows low-density residential uses alongside small-scale agricultural activities such as keeping livestock or maintaining orchards. This designation represents a transitional zone at the edge of the urban area. Parcels in R-1/A are unlikely candidates for dense infill but may suit hobby farm or rural residential programs that want proximity to city services.
How should developers approach the R-1/PD Planned Development residential zones?
R-1/PD (120 acres) means these residential parcels are governed both by the Single Family base standards and by a specific planned development agreement. Before proceeding with any project, obtain the recorded PD documents from the city to understand phasing obligations, improvement conditions, and any architectural or open-space requirements that override the base R-1 standards. Failure to identify PD conditions early is one of the most common sources of cost surprises in Willows residential acquisitions.
