A retirement community in Newtown is among 15 targeted by a U.S. Justice Department lawsuit over alleged Fair Housing Act and ADA violations.  The lawsuit was filed against J. Randolph Parry Architects and eight owners of multifamily properties designed by the architectural firm.  The Newtown facility listed in the suit is Church Hill Village.  The architectural firm is accused of failing to design and construct housing units and related facilities to make them accessible to people with disabilities. The lawsuit seeks compliance with the FHA and ADA, monetary damages to persons harmed by the lack of accessibility and civil penalties to the United States to vindicate the public interest.
