RR (Rural Residential) district. The RR zoning district is applied to areas of the City intended to accommodate residential neighborhoods with compatible agricultural uses, but where the primary uses are residential, and compatible accessory uses. The maximum allowable density ranges from 0.2 to two dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the RR map symbol (see Section 20-22.040). The RR zoning district implements and is consistent with the Residential—Very Low Density land use classification of the General Plan.

R-1 (Single-Family Residential) district. The R-1 zoning district is applied to areas of the City intended to be maintained as residential neighborhoods comprised of detached and attached single-family houses, clustered Residential hillside projects, and small multi-family projects, together with compatible accessory uses. The maximum allowable density ranges from two to 13 dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the R-1 map symbol (see Section 20-22.040). The R-1 zoning district implements and is consistent with the Residential—Very Low Density (where residential clustered on hillsides is desirable), Low Density/Open Space, Low Density, and Medium Low Density land use classifications of the General Plan.

R-2 (Medium Density Multi-Family Residential) and R-3 (Multi-Family Residential) districts. The R-2 and R-3 zoning districts are applied to areas of the City appropriate for residential neighborhoods with medium and higher residential densities, to provide home rental and ownership opportunities, and to provide a full range of choices in housing types to improve access to affordable housing. The maximum allowable density ranges from eight to 30 dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the R-3 map symbol (see Section 20-22.040). Densities of more than 30 dwellings per acre may be allowed within the Mixed Use land use designation of the General Plan. The R-2 and R-3 zoning districts implement and are consistent with the Residential—Medium Density and Medium High Density land use classifications of the General Plan.

TV-R (Transit Village-Residential) district. The TV-R zoning district is applied to areas within approximately one-half mile of a transit facility that is appropriate for mixed use development. Development should transition from less intense uses at the outlying edges to higher intensity uses near the transit facility. Residential uses are required, and ground floor neighborhood serving retail and live-work uses are encouraged. The maximum allowable density ranges from 25 to 40 dwellings per acre. The TV-R zoning district is consistent with and implements the Transit Village Medium land use classification of the General Plan.

MH (Mobile Home Park) district. The MH zoning district is applied to areas of the City occupied by and intended to be maintained as mobile home parks. The maximum allowable density ranges from four to 18 dwellings per acre. The MH zoning district implements and is consistent with the Residential—Mobile Home Park land use classification of the General Plan.

NMU (Neighborhood Mixed Use) district. The NMU zoning district is applied to areas within downtown Santa Rosa to allow for multi-family residential development in all residential or mixed-use buildings and a variety of uses that primarily serve local residents such as professional office, retail, entertainment, service, and other neighborhood-scale supporting uses. Housing development will include low- and mid-rise apartments and condominiums, as well as small-lot single-family attached dwellings (e.g., duplexes, triplexes, townhomes). Live-work spaces and maker-oriented uses are permitted subject to performance standards. The NMU zoning district implements and is consistent with the Neighborhood Mixed Use land use classification of the General Plan.

Application of requirements to property. The application of minimum parcel size requirements to property within the City is shown on the Zoning Map (Chapter 20-20) by means of a numerical or alphabetical suffix appended to the residential Zoning Map symbols (e.g., R-1-9, R-3-HD). Each applicable suffix is shown in the "Zoning District and Suffix" column of Table 2-3.

Attached housing projects. A condominium, townhome, or planned development project may be subdivided for ownership purposes into smaller parcels than allowed by Table 2-3, with the minimum lot area requirement, maximum lot coverage, and dimensions determined through the subdivision review process, provided that the overall development site complies with the lot area and width requirements of this Chapter, and the total number of dwellings does not exceed the maximum density established by the applicable zoning district.

Small lot residential projects. Small lot residential projects are allowed in compliance with Section 20-42.140 (Residential Small Lot Projects), instead of the requirements in Table 2-3.
