(A) Nonconforming uses.
(1) Any uses in existence prior to the date of enactment of this chapter which do not conform to the use restrictions of the established zoning district are nonconforming uses. All sanitary facilities inconsistent with the requirements of the city sewage chapter shall be brought into conformity according to the provisions of that chapter.
(2) All other nonconforming uses shall be subject to the following conditions.
(a) No use shall be expanded or enlarged except in conformity with the provisions of this or other applicable regulations.
(b) No structural alteration, addition, or repair to any nonconforming structure over the life of the structure shall exceed 50% of its assessed value at the time of its becoming a nonconforming use unless permanently changed to a conforming use.
(c) If the use is discontinued for 12 consecutive months, any future use of the building or premises shall conform to this chapter. The county assessor shall notify the city zoning administrator in writing of instances of nonconforming uses which have been discontinued for a period of 12 consecutive months.
(B) Substandard uses. Any uses of shorelands in existence prior to the date of enactment of this chapter which are permitted within the applicable zoning district, but do not meet the minimum lot area setback, or other dimensional requirements of this chapter are substandard uses. Substandard uses, including substandard sanitary facilities, shall be allowed to continue. However, any structural alteration or addition to a substandard use which will increase the substandard dimensions shall not be allowed.
