An Act amending the act of November 10, 1999 (P.L.491, No.45), known as the Pennsylvania Construction Code Act, in exemptions, applicability and penalties, providing for residential building construction defect remedies.

HB 1147 requires builders of new or rehabilitated residential buildings in Pennsylvania to fix significant defects (like water leaks or structural issues) at no cost to purchasers within two years of delivery. Builders must complete repairs within six months of being notified of a defect; if they fail to do so, purchasers can sue in court for 150% of the repair costs. The law applies to buildings delivered within two years of the bill's effective date and excludes cosmetic issues or defects covered by existing warranties. This directly affects homebuyers and builders by creating a clear, time-bound process for addressing construction flaws.
