Regulatory framework
The code baseline for Monroe County.
No separate 2026 technical IBC/IRC edition was identified in the county's published planning and zoning materials. Monroe County administers and enforces its Unified Development Code, amended effective December 16, 2025, for unincorporated areas outside city limits. The county requirements cover zoning certificates/structure placement, permitted uses, setbacks and dimensional standards, site plans, subdivision and land division, floodplain and other applicable county requirements; the county page states that other county ordinances and Iowa law also apply.
