500.09: NONCONFORMING USES:

Lawful nonconforming structures may be continued and maintained without being required to conform to the requirements of this article in accordance with the following:

A. Residential Single-Family: A nonconforming single-family dwelling may be maintained, remodeled, reconstructed, or expanded in size as long as there is no increase in the number of dwelling units. Secondary dwelling units may be constructed. The lot line of an existing single-family residential parcel may be adjusted as long as it does not result in an increase of allowable density.

B. Residential Multi-Family: Nonconforming multi-family residential dwellings may be maintained, remodeled, or reconstructed. The size of individual dwelling units may be increased, but additional dwelling units may not be added. Sound attenuation and avigation easement dedication requirements established by this article shall apply.

C. Nonresidential: Nonconforming nonresidential facilities may be maintained, altered, or reconstructed. However, any such work must not result in expansion of either the portion of the site devoted to the nonconforming use or the floor area of the buildings and must not result in an increase in the usage intensity (the number of people per acre) above the levels existing at the time of adoption of this chapter. Sound attenuation and avigation easement dedication requirements established by this article shall apply. (Ord. 1801, 12-3-2013)
