According to public record information, 624 W 1st St, Birdsboro, PA is one side of the semi-detached "twin" home. The other side is house number 626 W 1st Street.
Information on the TReND Multiple LIsting Service shows two tenant occupied units at the 624 W 1st street address. The lease for one of those units, a 3 bedroom 1 bath, reportedly will expire in October of 2010.
Birdsboro borough has a rental ordinance which requires landlords to register with the borough and have their properties inspected for rental compliance before tenant occupancy. I have included a link to that ordinance in .pdf file format at the Birdsboro borough website.
