Pennsylvania Registration

Under state law, most contractors who work on residential property (homes) are required to register as a “home improvement contractor” with the Pennsylvania Office of the Attorney General. Visit the Pennsylvania Attorney General’s Office website to search for home improvement contractors registered with the state. These contractors may or may not have a Philadelphia license (see above).

Before your contractor begins any work, make sure that he or she has obtained the required permits from L&I and post those permits on your property. A permit provides legal permission to start construction of a project in accordance with the building codes (laws) and lets certified inspectors stay involved in the process. You and your community benefit from their knowledge of the codes to ensure your project is built right and will be safe. For more information on permits, please see L&I’s publication, “Start Right.”

Consumer Protection
L&I works to ensure that the work regulated by the building codes (laws) is completed in compliance with the those codes. Occasionally, consumers experience problems with contractors that go beyond code compliance, such as failure to adhere to a contract or warranty. The Attorney General’s Office provides useful information on protecting yourself against fraud when hiring a contractor. If you believe you have been tricked or treated unfairly by a contractor, the Attorney General’s Office may be able to help.
