Quirks & watch-items
Quirks & watch-items
- Iowa uses UPC (2021) for plumbing, not IPC
- Cities >15K can adopt stricter codes
- IECC lags significantly: state still on 2012 IECC residential per IAC 661 Ch. 303 — DOE 2024-IECC review deadline ~late 2026
- DIAL (Department of Inspections, Appeals & Licensing) absorbed prior DPS State Fire Marshal building/code functions; some legacy URLs at dps.iowa.gov now redirect to dial.iowa.gov
