Overview
Idaho enforces a statewide building code with state-specific amendments. The Idaho
Division of Occupational and Professional Licenses (DOPL) oversees code adoption and
updates. While the state establishes a minimum standard, local jurisdictions may
implement additional requirements or amendments to address local concerns, such as
climate conditions or structural safety.
It is recommended to check with local building authorities to confirm any jurisdiction-specific requirements beyond the state-adopted codes.

State & Local
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.
