18.30.010 Purpose.

This chapter lists the uses that may be permitted within the residential zoning districts, the type of permit or approval required for each use, and basic development standards for the site and building. The purpose of each district is as follows:

A. RR – Rural Residential. The RR district is applied to areas of the city appropriate for rural single-family residential development or clustered development at densities up to two and one-half units per net acre. Designators (RR-40, RR-20, and RR-15) are used to denote minimum lot sizes of 40,000 square feet, 20,000 square feet, and 15,000 square feet, respectively. The RR district is consistent with and implements the rural residential (RR) land use designation of the general plan.

B. RS – Residential Single-Family. The RS district is applied to areas of the city appropriate for single-family residential uses in neighborhoods at densities of two and one-half to 10 units per net acre, subject to appropriate standards. The RS zoning districts generally apply to the single-family residential districts with development existing at the time of the adoption of this development code. The specific allowable density for each parcel is shown on the zoning map by a numerical suffix residential density designator (RS-12, RS-10, RS-8, RS-7.5, RS-7, and RS-6) corresponding to the minimum lot size (12,000, 10,000, 8,000, 7,500, 7,000 and 6,000, respectively). The RS district is consistent with and implements the low density residential (LDR) land use designation of the general plan.

C. RL – Residential Low Density. The RL district is applied to areas of the city appropriate for low density residential uses in a neighborhood with predominately detached single-family dwellings, but allows a diversity of compatible housing types and lot sizes from larger lot single-family dwellings to cottages, cluster, courtyard, and patio homes, and duplexes, at densities of two and one-half to 10 units per net acre. The RL district is consistent with and implements the low density residential (LDR) land use designation of the general plan.

D. RM – Residential Medium Density. The RM district is applied to areas of the city appropriate for residential uses with attached and detached dwellings, including a variety of housing types such as small lot single-family dwellings, townhomes, row houses, and cluster housing, at densities of 11 to 33 units per net acre, with provisions for appropriately scaled and located live/work units. The RM district is consistent with and implements the medium density residential (MDR) land use designation of the general plan.

E. RH – Residential High Density. The RH district is applied to areas of the city appropriate for compact, high density, multifamily residential development including apartments, townhomes, and condominiums at densities ranging from 33 to 100 units per net acre, with limited provisions for appropriately scaled and located live/work units. The RH district is consistent with and implements the high density residential (HDR) land use designation of the general plan. [Ord. 17-11 § 3 (Exh. 10); Ord. 12-4. DC 2012 § 122-77].

18.30.020 Table 18.30.020 – Residential districts – Allowed uses and permit requirements.

Table 18.30.020 identifies the uses allowed by the development code in each residential zoning district and the type of permit required to establish each use. See CDC 18.25.030(B) or Division VII of this title (Permits and Permit Procedures). Additional requirements may apply pursuant to Division IV (Development Standards) and Division V (Standards for Specific Uses) of this title.
