18.64.020 Purpose Revised 11/23

The purpose of this Chapter is to:

A.    Permit within Residential and Commercial Districts the development of townhouses which may be sold as individual lots and residences;

B.    Permit townhouse structures built to standards which are designed to include amenities usually associated with conventional single-family detached housing to ensure compatibility with the surrounding neighborhood;

C.    Promote affordable housing, efficient use of land and energy, and the availability of a variety of housing types in different locations;

D.    Promote infill development on physically suitable lands in residential areas, without adversely affecting adjacent development.

(Ord. 7364 §36, 2023; Ord. 5517 §1, 1995).

18.64.060 Platting requirements Revised 11/23

A.    In R-4, R 4-8, and R 6-12 Districts a subdivision or short plat is required for all townhouse developments so that individual dwelling units are divided onto lots with the structural walls located on the lot lines. In other Districts the platting of each individual dwelling unit is optional.

B.    When a townhouse development is platted, construction of townhouse dwellings may commence prior to final plat approval, provided:

1.    The proposed subdivision has received preliminary plat approval, and the necessary financial sureties have been filed as required in chapter 17.24 OMC, Olympia Platting and Subdivision Ordinance, to assure construction of required public improvements;

2.    Partial or complete construction of structures does not relieve the subdivider from, nor impair City enforcement of, conditions of subdivision approval;

3.    Construction may not proceed beyond foundations, and units may not be rented or sold, nor occupancy permits issued, until final plat or final short plat approval is granted.

C.    No subdivision or short subdivision of a site containing previously constructed dwellings is allowed unless all common walls meet or are reconstructed to current building code and fire code requirements for separately owned subdivided townhouse units, and all other standards of this Chapter are met.

D.    Undersized lots may be used for individual townhouse dwelling units without meeting the density and lot area requirements of this section, and without resubdividing, provided such lots were of record prior to the effective date of this chapter; and provided, they also have the minimum lot width for townhouses.

(Ord. 7364 §36, 2023; Ord. 6408 §28, 2006; Ord. 5517 §1, 1995).

18.64.080 Development standards Revised 11/23
