Iowa

Updated 3/15/2025

Overview

Iowa enforces minimum statewide building code requirements with statewide amendments,
but local municipalities may adopt more recent versions of building codes and implement
their own amendments. This results in variations across different jurisdictions.

While the 2015 International Residential Code (IRC) is the minimum standard and most
commonly used, particularly in larger cities, some jurisdictions have adopted the 2021 IRC. The
state mandates amendments to certain codes, including plumbing and electrical standards.

Since local municipalities may enforce more recent codes, it is advisable to check with the
local jurisdiction for specific code adoption and amendment details.

Since local jurisdictions may adopt more recent codes or have additional amendments, it is
strongly recommended to confirm code requirements with the local building department where
the project is located.

Hybrid Adoption

A hybrid adoption system means codes can vary at state and local level. Many times the state establishes a base code for building regulations and local jurisdictions then have the authority to amend or adopt more stringent requirements. This allows flexibility for cities and counties to tailor codes to their specific needs while maintaining a foundational standard set at the state level.
