Relating to certain construction defect litigation.

HB 3847 creates new pleading requirements for commercial construction defect lawsuits in Texas. It mandates that claimants (like businesses suing contractors or architects) must specifically describe defect manifestations, state the factual basis for defendant responsibility, and verify petitions with personal knowledge. The bill directly affects commercial property owners and contractors involved in construction defect claims by requiring more detailed initial court filings. These changes aim to clarify claims early in litigation, with the bill excluding residential properties, roads, and public infrastructure from its scope.
