Accessory Dwelling Units

The city’s zoning code permits internal, attached, and detached accessory dwelling units (ADUs) by right in all single-residence districts, subject to use-specific standards (§11-31-3). These standards address entrances, unit size, district dimensional standards, exterior appearance, and separate rental of units.

Design Review

The city's zoning code includes a chapter on design review (Chapter 71). It lists the purpose of the ordinance (§11-71-1) and its applicability (§11-71-2), including certain nonresidential projects and higher-density multifamily and attached single-family residential projects; design review may also be required as a condition of approval for special use or other permits. The code describes procedures for staff review and design review board review (§11-71-5). It lists review criteria and notes that conditions of approval may be imposed on projects to achieve compliance (§11-71-6). The establishment and organization of the Design Review Board is addressed in §11-66-6, including the composition of the Board, meeting procedures, and authority and duties.

Group Housing

The city's zoning code defines and regulates two types of community residences: family community residences and transitional community residences (Ordinance 5632). The distinguishing characteristic between these uses is length of stay and not the number of occupants.
