No. You do not forfeit the right to live in your house if it is unoccupied 12 months in a row, or for any amount of time. We believe this concern may be based in a misunderstanding of the term “non-conforming use.” A non-conforming use is one that is not permitted in the underlying shoreline designation. For example, a commercial amusement facility is not permitted in the Island Conservancy designation but may be present because it was established prior to effective date of the current regulations. As a non-conforming use, the commercial facility would be allowed to remain until such time the use is discontinued for 12 consecutive months. On the other hand, single-family residential use is a permitted use in all shoreline designations except Natural and is not subject to non-conforming use regulations in the SMP.
