This chapter shall apply to “horizontal property regimes” (condominium subdivisions), including the conversion of rental apartment buildings with five or more units to condominiums. Establishment of a condominium subdivision is also subject to RCW Chapter 64.32, zoning ordinance standards, and the application procedure and approval/disapproval regulations set forth in this title unless exempted. However, applicants for conversion of rental apartment buildings need submit only a proposed final plat and meet all building code requirements as determined by the building official. (Ord. 1211 § 2 (part), 2007).

A. Vertical Plane Datum. Plats for condominium subdivisions shall show three dimensions with elevation related to USGS and USC&GS datum.
B. Dimensions. Dimensions shall be in feet and inches conforming with architect’s drawing and shall be at a scale of not more than five feet to the inch.
C. Benchmarks. Two permanent benchmarks must be set on or near the building at ground level for future reference in locating units in the subdivision.
D. Elevations. The vertical position or positions of the plan of each floor or ceiling in any space unit shall be referenced to its elevation above USGS or USC&GS datum and shown on the face of the subdivision plat as floor elevation. A note should appear on the plat denoting reference plane for elevations.
E. Descriptions. Each floor plan of the permanent structure must be shown as well as basement and roof levels and area of subdivision plan. The dimensions and ties shown for each parcel must be definite enough with respect to both vertical and horizontal control so that the boundaries of each apartment may be accurately located by the use of standard survey methods.
F. Unit Lines. All units of apartment property lines shall be on the interior surfaces of the perimeter walls, floors, ceiling, windows and doors thereof.
G. Unit Numbers and Names. Apartment numbers and the subdivision unit numbers must be the same. The subdivision name and apartment building names must be the same.
H. Certificates. The condominium subdivision must contain all of the certifications and approvals required for any subdivision. Dedications of public areas and facilities and the grant to apartment owners of private easements in common areas and facilities shall be of sufficient quantity and quality to conform with minimum requirements and laws relating to fire, health and safety.
I. Percentage of Unit Interest. The percentage of undivided interest must be shown on the subdivision as well as in the declaration. The percentage should be expressed in decimal form. Any change of percentage interest shall be filed for record with the Cowlitz County auditor, and the auditor shall file a separate document of any such amendment with the date thereof.
J. Declaration. A declaration, the instrument by which the property is submitted to provision of the state law, must be filed at the time the plat is filed.
K. Notice of Bylaws. The bylaws under which the building, constituted as a condominium, is administered should not be a part of the subdivision. The current bylaws shall be recorded in the office of the Cowlitz County auditor. Reference to the general index or receiving number and to volume and page where the bylaws are recorded shall be included in any instrument of transfer of any or all units as a restriction on the title of such units. (Ord. 1211 § 2 (part), 2007).
