FIPS 19153
Article I · County Baseline

The county inherits from the state. And adds local rules.

Polk County generally enforces the 2021 International Building Code and International Residential Code with local amendments.

Polk County Public Works handles building permits for unincorporated areas and several smaller contract cities, while larger municipalities like Des Moines, West Des Moines, and Ankeny maintain their own independent building departments and permit portals. Development in unincorporated areas is subject to specific zoning ordinances and flood plain management regulations overseen by the county planning division.

Polk County enforces specific stormwater management and erosion control requirements for all land-disturbing activities exceeding one acre.

How this fits with the state

The state authority here is Iowa Division of Labor; Iowa Plumbing and Mechanical Systems Board. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
