The following RM zones are established; properties so designated shall be subject to the provisions contained herein:

RM-10

Medium density multiple-family residential zone

RM-20

High density multiple-family residential zone

RM-Core

Regional growth center-oriented high density multiple-family residential zone

(Ord. 3119 § 16, 2016; Ord. 2851 § 3, 2006; Ord. 2147 Exh. A, 1987).

20.25.005 Description and purpose.

The RM multiple-family residential zones are intended to reserve appropriately located areas for multiple-family living at a broad range of dwelling unit densities consistent with the Puyallup comprehensive plan. They are intended to protect the public health, safety and general welfare by ensuring that the opportunities to obtain reasonable cost housing exist for households representing a variety of income categories and lifestyles; facilitating the provision of utility services and other public facilities commensurate with anticipated population and dwelling unit densities; providing that multiple-family developments offer the amenities and conveniences necessary to assure the comfort and enhance the lifestyles of their occupants; and assuring the compatibility of multiple-family development with other uses and adjacent zoning districts. The RM multiple-family residential zone districts are further intended to provide housing types that possess attractive architectural and site design characteristics that are complementary to the community character of Puyallup.

The RM-10 multiple-family residential zone is more specifically intended to provide for a mix of single-family dwelling, duplex, triplex, fourplex and townhouse residential housing types. This zone is intended to provide an alternative to conventional single-family detached development patterns with many of the same attributes of such patterns including home ownership, distinct identity of dwelling units, and private open space.

The RM-20 and RM-Core multiple-family residential zones allow for a wider range of multifamily uses, including apartments, duplex, triplex, fourplex, townhouse and other multifamily residential housing types. The RM-20 and RM-Core zones are intended to provide for substantially higher density multifamily residential land uses, with RM-Core being specifically the densest and intended to promote a more compact form of residential land use. (Ord. 3119 § 17, 2016; Ord. 2454 § 1, 1995; Ord. 2147 Exh. A, 1987).
