16.08.010 Purpose.
This chapter provides regulations applicable to development and new land uses in the residential zoning districts established by 16.06.010 (Zoning Districts Established). The purposes of the individual residential zoning districts and the manner in which they are applied are as follows:
   A.   RR (Rural Residential) District. The RR zoning district identifies areas intended for low density, large lot single-family uses within a rural atmosphere, and may include the keeping of horses and other livestock, including kennels, as a permitted use in conjunction with the main residential use. Agricultural uses are allowable especially for buffering smaller lot single-family designations. The allowable density range is from 0.1 to 0.4 dwelling units per acre, with a minimum parcel size of 2.5 acres, unless designated within a master plan overlay. The RR zoning district is consistent with the large lot residential designation of the general plan;
   B.   ER-1 (Estate Residential 1) District. The ER-1 zoning district identifies areas appropriate for large lot single-family uses, and allows for the keeping of horses and other livestock in conjunction with the main residential use, including small scale agricultural uses appropriate far buffering smaller lot single-family designations. The allowable density range is from 0.4 to 1.0 dwelling units per acre, with a minimum parcel size of one acre, unless designated within a master plan overlay. The ER-1 zoning district is consistent with the large lot residential land use designations of the general plan;
   C.   ER-2 (Estate Residential 2) District. The ER-2 zoning district identifies areas appropriate for large lot single-family uses, and allows for the keeping of horses and other livestock in conjunction with the main residential use, including small scale agricultural uses appropriate for buffering smaller lot single-family designations. The allowable density range is from 1.0 to 2.0 dwelling units per acre, with a minimum parcel size of one-half acre, unless designated within a master plan overlay. The ER-2 zoning district is consistent with the single-family residential land use designations of the general plan;
   D.   ER-3 (Estate Residential 3) District. The ER-3 zoning district identifies areas appropriate for large lot single-family uses. This district is an appropriate transition zone between rural and the single family zones. The allowable density range is from 2.0 to 3.0 dwelling units per acre, with a minimum parcel size of ten thousand (10,000) square feet The ER-3 zoning district is consistent with the single-family residential designations of the general plan;
   E.   SF-1 (Single-Family Residential 1) District. The SF-1 zoning district is applied to parcels appropriate for single-family subdivisions with a uniform lot pattern possessing a minimum parcel size of seven thousand two hundred (7,200) square feet. The allowable density range is from 2.1 to 5.0 units per acre. The SF-1 zoning district is consistent with the single-family residential land use designation of the general plan;
   F.   SF-2 (Single-Family Residential 2) District. The SF-2 zoning district is applied to parcels appropriate for single-family subdivisions which may include detached and attached single-family dwelling units with common walls. For attached units configured within two to three unit configurations, a planned residential development application is required. The allowable density range is from 5.1 to 10.0 units per acre. The minimum parcel size for detached single-family units is four thousand three hundred fifty (4,350) square feet, although a smaller lot size can be considered for the clustering of units. This can be accomplished through a planned residential development application process and associated findings. See Section 16.16.020 “Planned residential development general standards” for additional details and requirements. The clustering of units through the planned residential development review process is to encourage an aggregate of open space with units on individual parcels with commonly maintained open space, and on-site recreational facilities required. The SF-2 zoning district is consistent with the residential land use designation of the general plan;
   G.   MF-1 (Multi-Family Residential 1) District. The MF-1 zoning district is applied to parcels appropriate for low density multi-family subdivisions which may include stacked flats or townhouse development, with ample amounts of open space, including required commonly maintained recreational and open space facilities. Air space, or postage stamp subdivisions providing individual ownership are allowed. The allowable density range is from 10.1 to fifteen (15) units per acre. The minimum parcel size for single-family detached units is five thousand (5,000) square feet. Clustering of units to provide aggregate open space is encouraged, with commonly maintained open space, and on-site recreation facilities. The MF-1 zoning district is consistent with the multi-family residential land use designation of the general plan;
   H.   MF-2 (Multi-Family Residential 2) District. The MF-2 zoning district is applied to parcels appropriate for high density multi-family development, in which attached or detached dwelling units may be air-space condominiums, or rented as apartments under single ownership. Senior housing, congregate care or group facilities are allowed, with commonly maintained recreational facilities and open space required. The allowable density range is from 15.1 to eighteen (18) units per acre. The MF-2 zoning district is consistent with the multi-family residential land use designation of the general plan; and
   I.   MF-3 (Multi-Family Residential 3) District. The MF-3 zoning district is applied to parcels appropriate for higher density multi-family development, in which attached dwelling units, senior housing and assisted living facilities are allowed with commonly maintained recreational facilities and open space required. The allowable density range is from 18.1 to 29 units per acre. The MF-3 zoning district is consistent with the multi-family residential land use designation of the general plan.
   J.   MF-4 (Multi-Family Residential 4) District. The MF-4 zoning district is applied to parcels appropriate for the highest density multi-family development, in which large buildings of attached dwelling units, senior housing and affordable housing are allowed with commonly maintained recreational facilities and open space required. The allowable density range is a minimum of 30 units per acre. The MF-4 zoning district is consistent with the multi-family residential land use designation of the general plan.
