As many builder members of the Builders Association of Metropolitan Pittsburgh (BAMP) became increasingly involved in the construction, ownership and management of multi-family communities, establishing an association with other apartment owners and investors was a logical partnership to ensure that the concerns of the multi-family housing industry were being addressed and its interests defended. Concerns about a revision of Pennsylvania's Landlord Tenant Act and the fear of government-imposed rent control measures led these industry leaders to establish a sister organization of BAMP in 1974. Today, AAMP has grown to over 200 companies - apartment builders, developers, owners, managers, investors, financial institutions, suppliers, subcontractors, and utilities - all working within the multi-family housing industry.
Since its inception, AAMP’s mission has been constant. AAMP's primary purpose is to promote the common interests of its members, to provide information and education while promoting multi-family living to the public. AAMP has been a positive influence in advocating pro-housing initiatives while promoting public policy actions that would enhance investment, sustainability and growth of the multi-family housing industry.
