What should developers know about Cotati zoning?
Cotati is a compact Sonoma County city that has built a deliberately modern, form-oriented zoning code into its 18 districts, with a strong emphasis on neighborhood character and transit-supportive development. The largest district is Neighborhood Low Density (NL) at roughly 241 acres, and together with Residential Very Low Density (RVL), Rural Residential (RR), Neighborhood Medium Density (NM), and Neighborhood Urban (NU) it forms a graduated residential ladder rather than a single dominant single-family zone. That tiering, plus a Transit Oriented Communities (TOC) district, signals a city actively shaping where and how it densifies.
What distinguishes Cotati is its collection of small, place-specific districts that read more like a form-based or specific-plan code than a conventional Euclidean map. Alongside corridor-based commercial zones - Commercial and Gravenstein Corridor (CG), Commercial and East Cotati Avenue Corridor (CE) - the city carves out La Plaza (LP), Santero Way (SW), Commerce Avenue (CA), Historic Core (HC), Downtown Commercial (CD), and the Northern Gateway (NG). These granular districts concentrate Cotati's commercial and mixed-use intent in its walkable center and along its key corridors. Industrial activity is handled through Commercial and Industrial (CI) and General Industrial (IG), with Open Space and Conservation (OSR) and Public Facility (PF) covering protected and civic land.
Building controls cover FAR, lot size, multi-unit, density, coverage, pervious surface, lot width, all setbacks, and height, plus an Assorted category. For developers, Cotati rewards a close reading of its corridor and downtown districts, where mixed-use and transit-oriented projects are most clearly invited, and where the city's small-town form standards will govern design. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.

Cotati zoning: frequently asked questions
What is the Transit Oriented Communities (TOC) district and where does it fit?
The Transit Oriented Communities (TOC) district is Cotati's vehicle for higher-intensity, transit-supportive development, reflecting its position on the SMART rail corridor. Developers pursuing denser, walkable, mixed-use housing near transit should target TOC-zoned land, where the city's intent and standards favor that product type over conventional low-density forms.
Why does Cotati have so many small, named districts like La Plaza and Santero Way?
Districts such as La Plaza (LP), Santero Way (SW), Commerce Avenue (CA), and Historic Core (HC) are place-specific zones that tailor standards to particular areas of the city's center, functioning much like a form-based or specific-plan code. This means design and use rules vary by district, so anyone working in the downtown or core must read the specific zone governing that block rather than a generic citywide commercial standard.
How is commercial development organized in Cotati?
Cotati ties much of its commercial zoning to corridors and places - Commercial and Gravenstein Corridor (CG), Commercial and East Cotati Avenue Corridor (CE), Downtown Commercial (CD), and the Northern Gateway (NG) - plus core districts like La Plaza and the Historic Core. The CG corridor is the largest commercial zone at roughly 89 acres, making the corridors and downtown the primary targets for retail and mixed-use projects.
What residential density options does Cotati offer?
The city uses a graduated ladder: Residential Very Low Density (RVL) and Rural Residential (RR) at the low end, Neighborhood Low Density (NL) as the largest residential zone, then Neighborhood Medium Density (NM) and Neighborhood Urban (NU) for more intensity, with the TOC district adding transit-oriented capacity. Choosing the right tier depends on the unit yield and form a project targets, and each carries the city's density, coverage, and setback controls.
Where can industrial users locate in Cotati?
Industrial activity is accommodated in the General Industrial (IG) district and the hybrid Commercial and Industrial (CI) district. These are modest in scale, consistent with Cotati's small size, so industrial and flex users should expect limited inventory and confirm that a specific parcel's standards support their intended operation.
