Relating to building codes applicable in the unincorporated areas of a county; authorizing a fee.

HB 882 requires new residential and commercial construction in unincorporated county areas to follow the 2025 version of the International Residential Code (for homes) or International Building Code (for businesses). It specifically applies to new single-family homes, duplexes, or significant renovations (increasing square footage/value by over 50%), but excludes modular homes built under other codes. Counties may choose to adopt newer building codes or set stricter standards for new construction through their commissioners court. This bill directly affects homeowners and developers planning new construction or major renovations in rural county areas outside city limits.
