§ 18.92.040 — Allowed Improvements and Expansions of Nonconforming Structures

A. Residential Expansions. Any residential expansion shall conform to the current applicable Zoning Code development standards, with the following two exceptions: 1. Residences with legal nonconforming parking. Expansions of single-family dwellings and duplexes with legal nonconforming parking are allowed up to a maximum 1,000 square foot expansion of floor area. For purposes of this Subparagraph, a “maximum 1,000 square foot expansion” includes all expansions in the aggregate since the parcel or structure became nonconforming. 2. Existing nonconforming side setbacks (three feet minimum). Existing nonconforming side setbacks of at least three feet are allowed to be extended to the rear of the dwelling for one-story expansions. B. Addition of Accessory Structure. The addition of one accessory structure related to a conventional single-family dwelling, other than an accessory dwelling unit, where either the dwelling or the parcel is legal nonconforming, and provided that all new structures comply with all other applicable regulations of this Zoning Code. C. Nonresidential Expansions. Expansions of nonresidential structures shall be allowed, where either the structure or the parcel is legal nonconforming, but only if the expansion is in full compliance with all applicable regulations of this Zoning Code.
