17.08.020 Nonconforming Uses

Any use which was legally established in accordance with the then existing policies, provisions, regulations or zoning code, but which does not conform to the provisions of this title, shall be deemed a nonconforming use.

  1. A nonconforming use established prior to the effective date of this title, or prior to any subsequent amendment which creates such nonconformity, may be continued, expanded and maintained, including necessary repairs, consistent with the provisions of this section. Continuation of a nonconforming use may include a change of ownership, tenancy or management where the previous line of business or other function is substantially unchanged.

  2. Nonconforming uses may be expanded through a planning director approval of a site plan application processed in conformance with sections 17.08.140, 17.08.150, 17.08.160 and the notice requirements of section 17.132.020 of this title. However, under no circumstances shall the expansion exceed a fifty percent (50%) increase in square footage. Notwithstanding anything to the contrary contained herein, if a proposed expansion would result in increasing the number of units which are available for occupancy, or increasing the density above the maximum allowed by this title, the expansion shall be denied. In addition to the factors specified in 17.08.160, an application shall not be approved if a determination is made that the expansion will constitute a public or private nuisance or will be objectionable by reason of noise, odor, smoke, dust, lights, vibrations, traffic, or drainage. Determinations made regarding these applications may be appealed in accordance with Chapter 17.136 of this title.

  3. Change in use: A nonconforming use may be changed to another nonconforming use of a similar or less intensive use. Whenever a nonconforming use has been changed to a less intensive use, or to a conforming use, such use shall not thereafter, be changed to a more intensive use.

  4. Discontinuance of uses: If the use of a building or premises does not conform to the land use regulations of the zone in which it is located, and that use is discontinued for a period of thirty-six (36) consecutive months, any subsequent use of the building or premises shall conform to the regulations of the zone in which it is located.

  5. Restoration: When a building or other structure, which does not conform to the provisions of this title is damaged or destroyed, it may be restored or rebuilt to accommodate its original use. Such restoration or rebuilding shall conform to the existing building requirements.

  6. Prior permits: Nothing contained in this title shall require any change in plans, construction size, or designated use of any building or structure or part thereof for which a building permit has been issued and is valid and unexpired, before the effective date of this title. An extension of these permits shall be granted the same as for any permit.
