Please note that the City does not recognize CPR parcels for zoning purposes. The State regulates CPR parcels mainly as a way to designate land ownership. A CPR parcel is not equivalent to a zoning lot, does not create entitlements, and does not increase development potential. Development standards are applied to the zoning lot regardless of whether the lot is owned by one entity or multiple entities under a CPR. Pursuant to HRS §514B-5, “Any CPR established under HRS Chapter 514B shall conform to the existing underlying county zoning for the property and all applicable county permitting requirements … to ensure the conformance of CPRs to the purposes and provisions of county zoning and development ordinances and HRS Chapter 205.” In the case of a property which includes one or more existing structures being converted to condominium status, the CPR must include a declaration that the CPR is in compliance with all zoning and building ordinances and codes, and all other permitting requirements. We recommend that you carefully consider these requirements and restrictions before submitting any property to the State to attempt to establish a CPR.
