The bill amends the Idaho Building Code Act by adding a new section, 39-4117, which outlines the procedures for processing building permits and ensuring timely reviews by local governments. It mandates that local governments requiring building permits must provide a detailed document outlining the permit process, accessible both online and in physical form. Applicants are required to submit complete applications and, if deemed incomplete, local governments must notify applicants within specified timeframes—ten business days for residential permits and twenty for commercial permits—regarding any missing information.

Additionally, the bill stipulates that local governments have the same timeframes to review submissions for completeness after receiving them. A determination of completeness does not equate to approval but allows the application to move forward to formal plan review. The bill also allows for written agreements between applicants and local governments to extend these timelines if necessary. An emergency clause is included, making the act effective on July 1, 2025.
