Relating to the regulation of building products by governmental entities.

HB 3299 prevents local governments (like cities or counties) from banning or restricting building products approved under national model codes. Specifically, it bars local rules that either prohibit such products or set stricter standards than those in nationally recognized codes published within the last three code cycles. Local governments may still adjust building codes for local concerns, but only if they don’t conflict with these national standards. This directly affects builders, contractors, and local officials who develop or enforce building regulations for residential or commercial construction.
