Grass Valley Zoning Code · 2026-06 edition · ingested 2026-07-06 · Grass Valley

17.22.020 - Purposes of the residential zones.

17.22.030 - Residential zone allowable land uses and permit requirements.

17.22.040 - Residential zone site planning and building standards.

17.22.010 - Purpose.

This chapter lists the land uses that may be allowed within the residential zones established by Section

17.12.020 (zoning map and zones), determines the type of planning permit/approval required for each use, and provides basic standards for site layout and building size.

17.22.020 - Purposes of the residential zones.

The purposes of the individual residential zones and the manner in which they are applied are as follows:

A.

RE (Residential Estate) Zone. The RE zone is applied to areas of the city that are appropriate for single dwellings, but where infrastructure limitations and/or environmental constraints limit the ability for development to achieve urban densities. This zone is also used to facilitate annexation to the city. The RE zone is consistent with and implements the urban estate density (UED) designation of the general plan.

B.

R-1 (Single Residential) Zone. The R-1 zone is applied to areas of the city that are appropriate for neighborhoods of single dwellings on standard urban lots, surrounding the more densely developed city core. The r-1 zone is consistent with and implements the urban low density (ULD) designation of the general plan.

C.

R-2 (Two-Family Residential) Zone. The R-2 zone is applied to areas of the city that are appropriate for a mixture of both single- and two-family dwellings. The R-2 zone is consistent with and implements the urban low density (ULD) and urban medium density (UMD) designations of the general plan.

D.

R-2A (Medium Density Residential) Zone. The R-2A zone is applied to areas of the city that are appropriate for neighborhoods with a variety of housing types located in proximity to parks, schools, and public services. The R-2A zone is consistent with and implements the urban medium density (UMD) designation of the general plan.

E.

R-3 (Multiple Dwelling Residential) Zone. The R-3 zone is applied to areas of the city that are appropriate for a variety of higher density housing types, located in proximity to parks, schools, and public services. The R-3 zone is consistent with and implements the urban high density (UHD) designation of the general plan.

17.22.030 - Residential zone allowable land uses and permit requirements.

A.

General Permit Requirements. Table 2-7 identifies the uses of land allowed by this development code in each residential zone, and the planning permit required to establish each use, in compliance with Section 17.20.030 (allowable land uses and planning permit requirements).

B.

Requirements for Certain Specific Land Uses. Where the last column in Table 2-7 ("specific use regulations") includes a section number, the referenced section may affect whether the use requires a minor use permit or use permit, and/or may establish other requirements and standards applicable to the use.
