How long might review take?
Approval must be obtained at least 10 days before construction begins; the ordinance does not publish a separate plan-review turnaround. Permits are valid for one year from issuance.
How are inspections scheduled?
Submit a completed building permit application with building/architectural plans and a site plan to the Adams County Engineer. The Engineer must approve it at least 10 days before construction begins; the ordinance requires timely inspections. The county's iWorQ portal supports building-permit applications and permit searches. Contact the Engineer at 641-322-3910 or the zoning office at 641-322-4312 for inspection arrangements.
Which codes and exemptions should I review?
Adams County Chapter 21 Zoning and building/entrance-permit requirements, including district setbacks, site-plan review, county health/water/sewage approvals, and certificate-of-occupancy requirements. The ordinance refers to a Building Code but does not identify a current 2026 model-code edition; applicable Iowa state electrical and other trade requirements may also apply. The ordinance requires a permit for any permanent building construction in Adams County. No broad minor/cosmetic exemption list was published; temporary uses that do not involve substantial buildings may receive a temporary revocable permit, and zoning exceptions for fences, landscaping, and small projections do not by themselves establish a building-permit exemption.
