Idaho Code § 67-6511A
Each governing board may, by ordinance adopted or amended in accordance with the notice and hearing provisions provided under section 67-6509, Idaho Code, require or permit as a condition of rezoning that an owner or developer make a written commitment concerning the use or development of the subject parcel. The governing board shall adopt ordinance provisions governing the creation, form, recording, modification, enforcement and termination of conditional commitments. Such commitments shall be recorded in the office of the county recorder and shall take effect upon the adoption of the amendment to the zoning ordinance. Unless modified or terminated by the governing board after a public hearing, a commitment is binding on the owner of the parcel, each subsequent owner, and each other person acquiring an interest in the parcel. A commitment is binding on the owner of the parcel even if it is unrecorded; however, an unrecorded commitment is binding on a subsequent owner or other person acquiring an interest in the parcel only if that subsequent owner or other person has actual notice of the commitment. A commitment may be modified only by the permission of the governing board after complying with the notice and hearing provisions of section 67-6509, Idaho Code. A commitment may be terminated, and the zoning designation upon which the use is based reversed, upon the failure of the requirements in the commitment after a reasonable time as determined by the governing board or upon the failure of the owner; each subsequent owner or each other person acquiring an interest in the parcel to comply with the conditions in the commitment and after complying with the notice and hearing provisions of section 67-6509, Idaho Code. By permitting or requiring commitments by ordinance the governing board does not obligate itself to recommend or adopt the proposed zoning ordinance. A written commitment shall be deemed written consent to rezone upon the failure of conditions imposed by the commitment in accordance with the provisions of this section.
