Will the proposed change make my existing lot or lots unbuildable?

Whether a lot is buildable (meaning a primary structure, such as a house, can be built on the property) is based on the size of the lot, when it was created, and whether it has been owned in common with abutting lots. Generally,

  1. If a lot was created through a land division after July 26, 1979, then the lot is buildable regardless of its size. (33.110.212.C.1)
  2. If the lot was created before July 26, 1979 through a land division or other instrument recorded with a county recorder, and the lot has not been owned in common with an abutting lot since July 26, 1979, then it is buildable regardless of its size. (33.110.212.C.3)

There are several other circumstances under which a lot is buildable. If your lot does not fit into one of the situations described above, then you can call the Bureau of Planning and Sustainability and we will help you determine whether your lot is currently buildable, and whether it will be continue to be buildable if the zoning is changed as part of the Comprehensive Plan update.
