How long might review take?

How are inspections scheduled?
No ordinary building inspections are performed because the county has no building code. Septic/wastewater permits and inspections are handled by Northeast Kansas Environmental Services at 785-985-2778; a wastewater permit approval must be received by Planning & Zoning before the building permit is issued. New county-road driveways require Road & Bridge consultation at 785-985-3535; state-highway driveways require KDOT coordination.
Which codes and exemptions should I review?
N/A for a specific current 2026 technical code edition. Doniphan County states it has no building codes, performs no ordinary building inspections, and issues no certificates of occupancy; it recommends building according to the International Building Code but does not enforce that recommendation. Septic and wastewater systems remain subject to inspection and approval. County building permits are required for additions and new buildings, including new residential and accessory buildings in the applicable unincorporated zoning areas. The official process expressly exempts roofing and exterior or interior repair/remodeling of a home. Wastewater approval is separately required before the building permit is issued; a minimum two-acre lot is required, and the county does not allow building or wastewater systems in an identified 100-year floodplain.
