What is Single-Family Zoning?
The Zoning Ordinance Title 14 of the San Rafael Municipal Code establishes standards and procedures so that development is consistent with San Rafael’s General Plan 2020. San Rafael is divided into Zoning Districts as shown on the zoning maps, which includes the allowable uses and construction requirements for single-family lots. There are six single-family residential (R) districts:
- R2a Min. lot size 2 acres
- R1a Min. lot size 1 acre
- R20 Min. lot size 20,000 sq. ft.
- R10 Min. lot size 10,000 sq. ft.
- R7.5 Min. lot size 7,500 sq. ft.
- R5 Min. lot size 5,000 sq. ft.
A “single-family use” is typically a house on a lot with front, side and rear yards. The Zoning Ordinance defines dwelling unit as “one or more rooms designed, occupied or intended for occupancy as separate living quarters for the exclusive use of one household, with a kitchen, sleeping facilities, and sanitary facilities.” A summary of the R zoning district Development Standards are provided below.
In addition to single-family residences, the following uses are permitted in the R Districts:
- home occupations
- public schools
- small (up to 8 children or adults) family day care
- second dwelling units
In R Districts, except for R2a, R1a and - H (Hillside Overlay), the following uses are allowed with the approval of a Use Permit:
- churches, places of worship (e.g., assembly halls)
- day care centers (15 or more children or adults)
- large (8 to 14 children or adults) family day care
- private schools
A complete list of uses that may be allowed in the R districts can be found in the zoning ordinance land use tables. See the ‘Single-Family Zoning Additional Standards’ handout for requirements for ancillary structures or uses.
