"Our mission is to advocate for and expand the residential building industry in Philadelphia." Since it was established in 1937, the Building Industry Association of Philadelphia has built a network of professionals to promote residential construction in Philadelphia, including multi-family and mixed use development. Our membership has grown to encompass the whole range of industry specialists – builders, real estate developers, subcontractors, designers, finance experts, brokers, product manufacturers, and others. For more than 79 years, we have joined forces to share ideas and create opportunities that will have a positive impact on the city’s housing market.
