House approves bill letting state approve alternative building codes for local adoption

The Utah House on March 4 passed first substitute Senate Bill 55, a measure that lets the state approve alternative building codes — including a rehabilitation code and a "dangerous building" code — that local governments may adopt for historic or existing structures.

Supporters said the bill clarifies the difference between codes the state "adopts" for statewide application and codes the state merely "approves" for local adoption, easing the financial burden of retrofitting older buildings to modern construction standards. "This would allow cities and counties to adopt a remodeling code that would be different than the standard new construction code," the sponsor said during floor debate.

Members questioned removing the phrase "nationally recognized" from a code-reference line and sought a definition of "dangerous building." The sponsor said the change was largely cleanup language and that the state would approve the dangerous‑building code and localities choosing to adopt it would have to adopt one approved by the State Uniform Building Code Commission, which reduces the risk of a patchwork of inconsistent local definitions.

After extended floor questioning, the House voted to pass the bill by a recorded vote of 52 yes and 0 no. The vote was publicly read by title and entered into the journal the same day.

The bill’s sponsors said the intent is technical and to preserve local options limited to state‑approved codes rather than impose a single statewide standard. The measure was advanced without additional amendments on the House floor and sent on per legislative process.
