17.16.010 - Purpose.

This section provides regulations for nonconforming land uses, structures, and parcels that were lawful before the adoption, or amendment of this zoning code, but which would be prohibited, regulated, or restricted differently under the current terms of this zoning code or future amendments. It is the intent of this zoning code to allow for the long-term continuance of nonconformities in an orderly manner, and provide for their possible transition to a conforming condition.
