Summary
In the unincorporated towns, the county zoning administrator inspects construction in two stages: a zoning permit before work starts and a follow-up inspection within 10 days of a completion notice before an occupancy permit issues.
Within ten (10) days after the notification of the completion of the erection, alteration or relocation of a Building, or of intent to commence a use, the zoning administrator or his deputy shall make an inspection of the premises and any Buildings thereon, and if such Building, use, or occupancy comply with the requirements of this Ordinance an occupancy and use permit shall be issued.
Full Breakdown
03(3)(A) says a zoning permit issues only once the application shows the proposed building, use, or occupancy complies with the ordinance, and a certification of that permit must be posted in a prominent place on the premises for the duration of construction. The second checkpoint comes at the back end. 03(3)(B) requires that "within ten (10) days after the notification of the completion of the erection, alteration or relocation of a Building, or of intent to commence a use, the zoning administrator or his deputy shall make an inspection of the premises and any Buildings thereon," and only if the building, use, or occupancy complies with the ordinance does an occupancy and use permit follow. 02(4). 02(1).
Violations & Fines
Occupying or using a building before the zoning administrator issues the occupancy and use permit is a zoning violation enforceable by the county under the Basic Zoning Ordinance's general penalty and injunction provisions, separate from any town building-code citation for uninspected construction work.
