§ 22.10.110. Minimum Site Area.

A.

Purpose and applicability. Minimum site area is the smallest existing lot size for which a building permit will be issued. Sections 22.10.100 through 22.10.110 set minimum site area standards for the use of existing lots of record. These standards are not to be used to determine the required parcel size for new land divisions, which are instead subject to Chapter 22.22 (Land Division Standards). Any legally created lot may be used for any use identified as allowable in the applicable land use category by Section 22.06.030 (Allowable Land Uses and Permit Requirements), regardless of whether the lot satisfies the minimum size requirements of Chapter 22.22 for new lots, provided that:

1.

The existing lot proposed for use is not smaller than the minimum site area required for the proposed use by Subsection C. (Required Area), or Chapter 22.30 (Standards for Specific Land Uses), or by the planning area standards of Article 9.

2.

The lot is of sufficient size to satisfy all applicable requirements of this Chapter, without the need for a variance based upon inadequate parcel size.

3.

The proposed use is authorized by the appropriate land use permit as determined by Article 2 or Chapter 22.30, or planning area standard of Article 9.

[Added 1984, Ord. 2163; Amended 1992, Ord. 2553]

B.

Area measured. For the purpose of determining whether a specific lot or contiguous lots satisfy these standards for minimum building site, no portion of an existing or proposed abutting street right-of-way shall be included in the area calculated.

C.

Required area. The following land uses shall be located only on sites with the minimum areas specified, unless other minimum site area requirements are established by Chapter 22.30 for specific uses, by Chapter 22.14 for combining designations or by planning area standards in Article 9.
