San Ramon, California Zoning Map

High Density Residential (RH, 108.58 acres), Medium High Density Residential (RMH, 170.62 acres), and Medium Density Residential (RM, 223.91 acres) are the dedicated multifamily zones, while the downtown mixed-use districts (CCMU, DMU-N, DMU-S) add residential capacity in a mixed-use context. Collectively, the city has a meaningful multifamily land base distributed between conventional residential zones and the planned downtown. Density bonus applications on qualifying sites can unlock additional units, particularly in the denser residential and mixed-use districts near City Center.

The NWSP district at 287.07 acres governs a master-planned mixed-use area in northwest San Ramon incorporating residential, retail, office, and open space uses under a specific plan framework. Like other PD and specific-plan zones in the city, NWSP requires that developers consult the actual specific plan document rather than the base zoning code for permitted uses and development standards. This area has been the subject of active development activity involving higher-density housing and neighborhood commercial.

The GC district at 306.59 acres encompasses the golf course properties that are a defining amenity in several of San Ramon's master-planned communities. GC-designated land is committed to recreational golf use and is generally not available for residential or commercial redevelopment without a general plan amendment and rezoning. However, proximity to GC parcels is a relevant valuation factor for adjacent residential properties, and any changes to golf course land use would be a significant planning event for adjacent neighborhoods.

Community Commercial (CC, 138.56 acres), City Center Mixed Use (CCMU, 172.42 acres), Mixed Use Commercial Emphasis (MUX, 50.47 acres), Thoroughfare Commercial (CT, 11.56 acres), and Mixed Commercial (MC, 21.93 acres) form the commercial land base. The Administrative Office (OA, 18.48 acres) and Limited Office (OL, 18.67 acres) districts accommodate professional and medical office uses, while the Medical Center (M-1, 29.70 acres) and Health Facility (M-2, 14.53 acres) zones reflect the concentration of healthcare uses near the Bishop Ranch area. San Ramon's strong household incomes support active neighborhood retail and services demand.

The RS-10 district at 1,166.61 acres covers the city's primary single-family residential base. California's ADU law permits accessory dwelling units on these parcels by right under objective standards, and SB-9 allows qualifying single-family lots to accommodate two units or a lot split with up to four units total. San Ramon's relatively large RS-10 lots may meet SB-9 minimum-size thresholds in many cases, making infill strategies viable. Investors should confirm lot dimensions and current city ADU standards before modeling unit yields on a specific parcel.
