30.28.075 Nonconforming uses - structures.
The following requirements apply to structures, whether conforming or nonconforming, that house or contain nonconforming uses:
(1) Improvements. No structure containing a nonconforming use shall be enlarged, extended or structurally altered, whether the structural alterations meet the bulk requirements of this code or not, unless the nonconforming use is changed to a use permitted by this code; except that repair to the existing structure including ordinary maintenance or replacement of walls, fixtures, or plumbing shall be permitted so long as the exterior dimensions of the structure, as it existed on the effective date of the nonconformance are not increased;
(2) Restoration. A structure housing a nonconforming use that is accidentally destroyed may be fully restored only if the setback and yard requirements of chapter 30.23 SCC are met unless the structure is listed on the National Register of Historic Places, Washington State Cultural Resource Inventory, or Snohomish County Cultural Resource Inventory, in which case, the structure housing the nonconforming use may be restored and located in its former location despite noncompliance with the bulk regulations:
(a) To restore a destroyed structure housing a nonconforming use, a building permit must be submitted to the department within one year of the destruction; and
(b) A structure shall be considered destroyed for purposes of this section if the restoration costs exceed 75 percent of assessed value of record when the damage occurred. (Added by Amended Ord. 02-064, Dec. 9, 2002, Eff date Feb. 1, 2003).
