The city's residential zoning districts are listed in table 2-1. Whenever this zoning ordinance refers to "residential" zoning districts or "R" zoning districts, it is referring to these districts.

(Ord. No. RZ-2018-11-06, § I, Exh. A(27.22), 11-27-2018)

(a)

General. Residential zoning districts are primarily intended to create, maintain and promote a variety of housing opportunities for individual households and to maintain and promote the desired physical character of existing and developing neighborhoods. While the districts primarily accommodate residential uses, some nonresidential uses are also allowed. The various R district are primarily differentiated on the basis of allowed uses, allowed building types and lot and building regulations.

(b)

RS, Single-Dwelling Detached Districts. The RS districts are primarily intended to accommodate detached houses. The number suffix attached to RS district names is a shorthand reference to the minimum lot width required for detached houses.

(c)

RSA, Single-Dwelling Attached Districts. The RSA districts are primarily intended to accommodate attached houses, two-flats and three-flats (also known as "duplexes" and "triplexes," respectively). The number suffix attached to RSA district names is a shorthand reference to the maximum density allowed for attached house developments in the subject district.

(d)

R3, Two- and Three-Unit District. The R3 district is primarily intended to accommodate two-flats and three-flats (also known as "duplexes" and "triplexes," respectively).

(e)

RM, Multi-Unit Districts. The RM districts are primarily intended to accommodate multi-unit residential buildings. The number suffix attached to RM district names is a shorthand reference to the maximum density allowed for multi-unit residential developments.

(Ord. No. RZ-2018-11-06, § I, Exh. A(27.23), 11-27-2018)

Uses are allowed in R districts in accordance with the use regulations of article VII.

(Ord. No. RZ-2018-11-06, § I, Exh. A(27.24), 11-27-2018)

(a)

Allowed residential uses shall occupy residential buildings, which are allowed in R districts in accordance with table 2-2.

(b)

Allowed public and civic uses shall occupy civic buildings, which are allowed in R districts, as indicated in table 2-2.

(Ord. No. RZ-2018-11-06, § I, Exh. A(27.25), 11-27-2018; Ord. No. RZ2023-12-10, § I, 12-19-2023)

(a)

Accessory uses and structures. See article 7, division 11 of this chapter.

(b)

Parking. See article VIII.

(c)

Landscaping and screening. See article IX.

(Ord. No. RZ-2018-11-06, § I, Exh. A(27.26), 11-27-2018)

Detached houses are allowed in all RS districts, subject to compliance with the lot and building regulations of table 2-3 (see also figure 2-1).

(2)

Non-conforming and enclosed accessory structures that exist on the effective date specified, December 19, 2023, but that do not comply with the regulations of this article may be converted to an ADU so long as the modification does not result in the structure exceeding the extent of noncompliance with the regulations of this article (article 2 of chapter 27).

(Ord. No. RZ2023-12-10, § I, 12-19-2023)

(a)

Description. Attached accessory dwelling units (AADUs), formerly referred to as secondary suites, are contained wholly within the principal dwelling unit on the property (i.e., detached house).

(b)

Applicability. All AADUs are subject to compliance with the regulations of this section.

(2)

Adding floor area to an existing detached house to accommodate an accessory dwelling unit; or

(3)

Constructing a new detached house that includes an accessory dwelling unit within the principal building.

(d)

Location of entrances. Only one entrance to a detached house containing an AADU may be located on a facade that faces a street, unless the detached house had an additional street-facing entrance before the AADU was created.

(Ord. No. RZ2023-12-10, § I, 12-19-2023)
