BIDDEFORD — There will be an open house for the affordable senior apartments at the Convent at Mission Hill, on the corner of Bacon and High streets, from 3-6 p.m. Friday.

Mission Hill, formerly known as the St. Andre’s Catholic Church campus, consists of four buildings: the convent, church, school and rectory. The entire St. Andre’s campus redevelopment represents a more than $5 million investment in the neighborhood by local non-profit owners Southern Maine Affordable Housing (SMAH) and Biddeford Housing Authority (BHA).

Fifteen units of affordable senior housing have been added to the convent. Applications are now being accepted by emailing [email protected] or calling Mary at 773-4140, ext 301. Tenants must be 55 and older and earn no more than 60 percent of the area median income. Occupancy is expected to begin in late March or April.

The project has utilized historic tax credits and thus has been redeveloped according to the strict architectural standards of the National Park Service and Maine State Historic Preservation. The convent is part of a larger redevelopment concept pursued by the SMAH/BHA.

The St. Andre School already contains 35 units of senior affordable housing. SMAH/BHA purchased the building last year from the Catholic Diocese of Portland and has completed a full rehabilitation, improving the quality of life for these tenants. Applications for the wait list are also being taken for the school apartments.
