Regulatory framework
The code baseline for Ida County.
Ida County Ordinance No. 2 governs zoning in the unincorporated area and was included in the county’s 2022 readopted code under Ordinance No. 33. A Certificate of Zoning Compliance is required before land or a building may be occupied or used, and no permit for excavation, erection, or alteration of a building may be issued before the certificate application is made. Water-supply and sewage-disposal plans must be approved by the County Health Department before a permit for a use is issued. No specific 2026 county technical building-code edition was identified; applicable Iowa State Building Code, electrical/plumbing/mechanical, septic, well, floodplain, health, and municipal requirements remain separate.
