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 appropriate for detached single-family dwelling units with appropriate accessory structures and uses in semi-rural areas and areas where scenic and natural resources should be protected, together. The RE Zone may also allow mobile and modular homes, agricultural uses, public facilities, and other uses that are compatible with rural estate single-family neighborhoods. Horses and other farm animals are also allowed in this zone in compliance with Section 17.430.050 (Animal Keeping). This zone allows a maximum density of 1.0 dwelling unit per two gross acres of land. The RE Zone is consistent with the Very-Low-Density Residential (VLDR) land use designation of the General Plan.
B. 
RR (Residential Rural) Zone. The RR Zone is applied to areas appropriate for detached single-family dwelling units with appropriate accessory structures and uses in a semi-rural setting. The RR Zone may also allow mobile and modular homes, public facilities, and other uses that are compatible with rural single-family neighborhoods. Horses and other farm animals are also allowed in this zone in compliance with Section 17.430.050 (Animal Keeping). This zone allows a maximum density of 2.0 dwelling units per gross acre of land. The RR Zone is consistent with the Very-Low-Density Residential (VLDR) land use designation of the General Plan.
C. 
RL (Residential, Low-Density) Zone. The RL Zone is applied to areas appropriate for a range of detached single-family residential dwellings on standard suburban parcels, together with appropriate accessory structures and uses. The RL Zone may also allow mobile and modular homes, condominiums, townhomes, public facilities, and other uses that are compatible with low-density single-family neighborhoods. This zone allows a density ranging from 2.1 to 7.0 dwelling units per gross acre. The RL Zone is consistent with the Low-Density Residential (LDR) land use designation of the General Plan.
D. 
RM (Residential, Medium-Density) Zone. The RM Zone is applied to areas appropriate for neighborhoods with a variety of housing types located in proximity to parks, schools, and public services. The housing types range from attached and detached single-family residential dwelling units, duplexes, triplexes, fourplexes, condominiums, townhomes, mobile home parks, recreational vehicle parks, as well as accessory structures and uses. The RM Zone may also allow limited neighborhood serving commercial uses on small appropriately located individual parcels or in small pedestrian-oriented neighborhood centers, public facilities, and other uses that are compatible with medium-density neighborhoods. This zone allows a density ranging from 5.1 to 14.0 dwelling units per gross acre. The RM Zone is consistent with the Medium-Density Residential (MDR) land use designation of the General Plan.
E. 
RH (Residential, High-Density) Zone. The RH Zone is applied to areas appropriate for a variety of multi-family attached housing types (for example, apartments, garden style units, condominiums, townhomes, etc.), as well as accessory structures and uses primarily on larger parcels where site design can provide the desired mixture of housing types, aesthetic and functional open space areas, and other features that enhance the development and neighborhood. The RH Zone may also allow limited neighborhood serving commercial uses on small appropriately located individual parcels or in small pedestrian-oriented neighborhood centers, public facilities, and other accessory structures and uses that are compatible with high-density neighborhoods. This zone allows a density ranging from 14.1 to 22.0 dwelling units per gross acre. The RH Zone is consistent with the High-Density Residential (HDR) land use designation of the General Plan.
F. 
RVH (Residential, Very-High-Density) Zone. The RVH Zone is applied to areas appropriate for apartments, senior housing, and housing affordable to lower and moderate income families located near commercial areas and public services. The RVH Zone may also allow limited neighborhood serving commercial uses on small appropriately located individual parcels or in small pedestrian-oriented neighborhood centers, public facilities, accessory structures and uses, and other uses that are compatible with high-density neighborhoods. This zone allows a density ranging from 22 to 32.0 dwelling units per gross acre. The RVH Zone is consistent with the Very-High-Density Residential (VHDR) land use designation of the General Plan.

A. 
Compliance with density thresholds. The minimum and maximum density thresholds indicated in Table 2-4 (Development Standards for Residential Zones) shall apply to development in residential zones. Development shall not be allowed at less than or more than the indicated density thresholds, except in the following instances:
1. 
Less than minimum density threshold. A proposed project may be allowed at less than the applicable minimum density threshold only if the project complies with Chapter 17.645 (Transfer of Development Rights). Additionally, one single-family dwelling unit may be allowed on legal lots that require higher densities, if the zone allows for such use.
2. 
Greater than maximum density threshold. A proposed project may be allowed at greater than the applicable maximum density threshold only if the project complies with Chapter 17.310 (Affordable Housing – Density Bonuses), Chapter 17.645 (Transfer of Development Rights), or permitted by this section.
B. 
Allowed by right. A proposed residential project that is consistent with the applicable density range shall be allowed by right, subject to any permits required by Table 2-2 (Allowed Uses and Permit Requirements in Residential Zones).
C. 
Development standards. Projects that are allowed by right shall be consistent with all applicable development standards. Projects proposing a single-family may comply with RL Zone standards, and projects transferring units, pursuant to Chapter 17.645 (Transfer of Development Rights), may comply with standards for zone that best fits the project density, as approved by the City.
D. 
Amenity density incentives. A proposed project in a residential zone, except the RE and RR Zones and including the mixed use zones, may qualify for an amenity density increases by providing the necessary amenities identified in Table 2-5 (Amenity Density Incentives for Projects in Residential Zones) and obtaining approval of a site plan and design review in compliance with Chapter 17.630 (Site Plan and Design Review). The amount of the increased density shall not exceed the mid-point of the next highest residential density range; or shall not exceed the 50% above the maximum of the density range stated for the RVH, MU, MU-E, DV Zones.
For the purposes of this section, the term "amenity" shall be broadly defined to include natural features (e.g., trees, streams, green space, views, etc.) as well as amenities for the benefit of the community (e.g., street furniture, childcare space, community space, street awnings, etc.). An amenity shall not include cash or the provision of cash in lieu of a physical amenity.
