Except as otherwise provided in this chapter, the lawful use of any building, land or premises, existing on the effective date of adoption or amendment of this chapter, may be continued although such use does not conform to the provisions hereof. If such nonconforming use is discontinued for a period of 12 months or more, any future use of said building, land or premises shall be consistent with the provisions of this chapter.
A structure occupied by a nonconforming residential use may be converted to any of the following uses:
(1) 
An adult family home that is similar in size, facilities and occupancy to the nonconforming residential use.
(2) 
A boarding home that is similar in size, facilities and occupancy to the nonconforming residential use.
(3) 
A mental health facility that:
(a) 
Provides residential treatment; and
(b) 
Is similar in size, facilities and occupancy to the nonconforming residential use.
(4) 
A substance abuse facility that:
(a) 
Provides residential treatment; and
(b) 
Is similar in size, facilities and occupancy to the nonconforming residential use.
(Ord. 2004-014 § 2, 2004)
Nonconforming adult businesses shall terminate within one year from the date that the use became nonconforming, except that the hearing examiner may approve up to four additional one-year extensions; provided, that:
(1) 
An application is submitted by the owner or operator of such business to the Whatcom County planning and development services department at least 120 days prior to the date that such business must terminate; and
(2) 
The hearing examiner shall find, in connection with such adult business, that:
(a) 
The applicant had made, prior to the use becoming nonconforming, substantial financial expenditures related to the adult business; and
(b) 
The applicant has not recovered, through sales, depreciation or other tax benefits, a reasonable portion of the financial expenditures related to the adult business that were made prior to the use becoming nonconforming; and
(c) 
The applicant could not recover, through sales, depreciation or other tax benefits, a reasonable portion of the financial expenditures by converting the nonconforming adult business to a use that is permitted or allowed as a conditional use in the zoning district; and
(d) 
The period for which such adult business may be permitted to continue is the minimum period sufficient for the applicant to recover, through sales, depreciation or other tax benefits, a reasonable portion of the financial expenditures incurred related to the adult business, but in no case shall exceed one additional year at a time; and
(e) 
The economic hardship to the applicant is found to outweigh the public benefit to be gained by termination of the nonconforming use.
For the purpose of this section, "financial expenditures" shall mean the capital outlays made by the applicant to establish the adult business, exclusive of the fair market value of the building in which the use is located and exclusive of any improvements unrelated to the nonconforming adult business. "Financial expenditures" shall not include improvements to the building for which all required permits were not obtained. "Financial expenditures" shall not include materials for sale or rent that could be moved to another legal site and placed for sale or rent at that site.
(Ord. 99-070 § 2, 1999)
(1) 
Nonconforming uses may be extended throughout any building partially occupied by such use at the time of passage of the ordinance codified in this section, except for nonconforming adult businesses, which shall not be extended to other parts of the building.

(a) 
Nonconforming adult businesses, which shall not be expanded; and
(b) 
Personal wireless service facilities regulated under WCC § 20.13.070(1) through (3).
The expansion must be on the parcel as it existed at the time the use became nonconforming and the use shall not expand on adjacent parcel(s). The expansion shall be approved if it is consistent with the applicable zoning regulations except the use restrictions and complies with WCC § 22.05.026(3)(b) to (3)(i).
(3) 
For the purposes of this section, the expansion of a nonconforming surface mining operation (which requires a conditional use permit) shall mean:
(a) 
Any lateral excavation outside of the footprint of the nonconforming mine as it existed on the effective date of the amendment codified in this subsection; or
(b) 
Any further excavation within a five-year time of travel boundary for delineated wellhead protection areas (areas within the one-year and two-year time of travel boundaries are included in the five-year time of travel boundary); or
(c) 
Any further excavation within 10 feet of the seasonal high water table if mining is within a 10-year time of travel boundary for delineated wellhead protection areas, but outside of a five-year time of travel boundary; or
(d) 
Any further excavation within five feet of the seasonal high water table if mining is within a critical aquifer recharge area, but outside of the 10-year time of travel boundary for delineated wellhead protection areas.
This subsection (3) does not apply to mining operations conducted in accordance with a previously approved conditional use permit, mining operations conducted in accordance with a previously approved county surface mining permit, nor to mining operations within the mineral resource lands overlay zone that have obtained administrative approval. Subsections (3)(b) and (3)(c) of this section do not apply when the well was drilled after the effective date of the amendment codified in this subsection.
(4) 
Whatcom County shall not pursue enforcement action for failure to possess a conditional use permit against any operator or owner of a nonconforming surface mining operation if all of the following circumstances apply:

(i) 
Within 120 days of the effective date of the amendment codified in this subsection; or

(c) 
The owner or operator continues to actively seek the conditional use permit after the application is submitted.

The change of a nonconforming use to another type of a nonconforming use shall be conditionally permitted, except that a nonconforming use shall not be changed to an adult business. The change of nonconforming use shall be approved if it is consistent with the applicable zoning regulations, except the use restrictions, and complies with WCC § 22.05.026(3)(b) to (i), providing such change does not require the provision of water and sewer utility services at a level greater than that currently available to the subject property, and that the new nonconforming use does not result in greater impacts upon surrounding properties than did the original nonconforming use.

.072 
The following formula shall be used to determine the maximum number of lots which shall be permitted by the consolidation of substandard lots. This formula is not applicable to satisfying the requirements of Chapter 20.89 WCC.
The total area of all lots subject to consolidation under this section shall be added together and the sum divided by the minimum noncluster lot size for the zoning district. The whole number quotient shall be the maximum number of lots; provided, that an additional lot shall be allowed if the quotient contains a fraction of 0.5 or more; and provided further, that the number of lots shall not exceed the original number of lots. Parcels recognized as permitted lots under this subsection are not required to obtain administrative approval under WCC § 20.83.073.
