AB 450 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: applicability of the commercial building code to certain buildings. (FE)

AB 450 creates a new statute (101.02(26)) specifying that Wisconsin’s commercial building codes (Chapters SPS 361-366) apply to public buildings, structures, or places of employment when their plans are submitted to the state department or a local government authorized to review such plans under statute 101.12. It explicitly excludes Section SPS 361.03(7) from applying to these public projects. This bill directly affects public construction projects requiring building plan reviews by state or local authorities, effective August 1, 2025, with local jurisdictions required to comply by April 1, 2026. The change clarifies code applicability without altering the underlying building safety standards.
