Unofficial copy. It may be out of date. Not legal or zoning advice. Zoning rules change, and only the city or county can say for sure what is allowed on a property. Confirm with the city or county planning department before you buy, sign or build.

A lot divided by a zone boundary shall be subject to the following special regulations:
(1) A use allowed in the less restrictive zone but not allowed in the more restrictive zone may be allowed to extend into the more restrictive zone but not more than 50 feet by approval of the land use authority, if the land use authority finds that the extension is required for the reasons of justice and equity and will not be harmful to neighboring property or human values.
(2) A substandard lot may have area added from a legally existing, legally created, or existing substandard lot through a subdivision approval or by a variance issued by the land use authority if the total lot area would not equal the minimum lot area of the zone, as long as the creation of the new lot or lots, or the addition of land to an existing lot:
(a) would not create undesirable land patterns or prevent desirable subdivision designs in the area;
(b) would not be detrimental to the development of required or desirable streets, utilities, or other public facilities or service; and
(c) would provide a usable and desirable lot for the uses and densities allowed.
(3) The uses allowed on any portion of the new lot shall only be those allowed in the district in which such portion of the lot is located.
(4) Any such enlarged lot shall not be re-subdivided except through submission and approval of a subdivision plat.
