15.10.010 Purpose and intent.

A. Purpose and Intent. The purpose and intent of the residential zoning districts is to provide for a range of residential densities and dwelling types consistent with the plans and policies of the general plan land use and other elements and to foster high quality, attractive and livable residential neighborhoods.

B. Residential Districts. The purpose of each residential district is as follows:

1. RL Residential – Low Density District. To provide for the development and preservation of low density neighborhoods with single-family detached or attached residences and condominiums. Maximum density is eight units per gross acre.

2. RM Residential – Medium Density District. To provide for the development and preservation of medium density neighborhoods containing detached and attached single-family homes on smaller lots, duplexes, townhomes, apartments, and condominiums. Each project will have ample common open space and recreation facilities. Maximum density is 18 units per gross acre.

3. RH Residential – High Density District. To provide for the development and preservation of high density neighborhoods consisting primarily of attached and multiple dwelling units such as townhomes, apartments, condominiums, and senior housing. Each project will have ample common open space and recreation facilities. Maximum density is 30 units per gross acre.

4. RVH Residential – Very High Density District. To provide for the development and preservation of very high density neighborhoods consisting primarily of multiple dwelling units such as apartments, condominiums, and senior housing. Each project will have ample common open space and recreation facilities. Maximum density is 50 units per gross acre.

5. PRD Planned Residential Development Overlay District. This is an overlay district which is to be combined with one of the residential base districts described preceding. The PRD overlay district provides for the development and preservation of planned unit developments with attached homes, detached homes, or a mixture of both. Each project will have ample common open space and recreation facilities. Setbacks and other development standards are to be tailored specifically to each project. [Ord. 2010-126 § 1 (Exh. A); Ord. 2010-123 § 3 (Exh. A)].

15.10.020 Permitted uses in residential districts. Amended Ord. 2024-237

A. Development Permits Required. Table 15.10.020 in this section identifies whether a use or structure is permitted within a zoning district. However, in most cases development to establish a land use requires approval of a site development permit and/or other permits as set out in Chapter 15.74 AVMC, Discretionary Permits.

B. PRD Permitted Uses. Per AVMC 15.10.040, the permitted uses within the planned residential development district shall be the same as those in the underlying base district. Therefore, permitted uses for the PRD district are not included in Table 15.10.020.

C. Table of Permitted Uses. Table 15.10.020 specifies those uses and structures which are permitted within each residential district. If a use or structure is not listed as permitted, it is prohibited unless specifically determined to be permitted in accordance with AVMC 15.06.050, Unlisted land uses. The letters in the columns beneath the district designations mean the following:

1. “P” – The use is permitted as a principal use within the district.

2. “A” – The use is permitted only if accessory to the principal use on the site.

3. “C” – The use is permitted as a principal or accessory use if a conditional use permit is approved.

4. “AUP” – The use is permitted as a principal or accessory use if an administrative use permit is approved.

5. “TUP” – The use is permitted on a temporary basis if a temporary use permit is approved.

6. “NP” – The use is not permitted in the district.
