HB 2450 changes elevator inspection requirements for buildings with four stories or less. The bill amends the Health and Safety Code to reduce the inspection frequency for low-rise buildings from once per year to once every five years, provided the change complies with federal regulations under the Americans with Disabilities Act (ADA). The bill also establishes penalties for overdue inspections, requiring power disconnection if an elevator in a four-story or smaller building has not been inspected for over six years. The Texas Commission of Licensing and Regulation is tasked with adopting rules to implement the changes.
