Regulatory framework
The code baseline for Story County.
No separate county-adopted 2026 technical IBC/IRC building-code edition was identified. For unincorporated Story County, Planning and Development enforces the Story County Land Development Regulations, including zoning districts, permitted uses, site planning, subdivision, floodplain management (Chapter 80), signage, grading, and related development standards, and performs on-site zoning inspections. Iowa State electrical permits and inspections are handled by the State, not Story County. Wastewater proposals require Story County Environmental Health review before a zoning permit is issued.
