What this bill does

Plain-language analysis by the nonpartisan Legislative Reference Bureau

Under this bill, the commercial building code rules promulgated by the Department of Safety and Professional Services and in effect on August 1, 2025, apply to a public building, public structure, or place of employment if the plans for the public building, public structure, or place of employment are submitted for examination for compliance with the commercial building code no later than April 1, 2026. Before September 1, 2025, DSPS’s commercial building code rules incorporated by reference the 2015 International Building Code; however, effective September 1, 2025, the commercial building code rules incorporate by reference the 2021 International Building Code.

Because this bill may increase or decrease, directly or indirectly, the cost of the development, construction, financing, purchasing, sale, ownership, or availability of housing in this state, the Department of Administration, as required by law, will prepare a report to be printed as an appendix to this bill.
