The Hyannis Main Street Waterfront Historic District (HHDC) was
created in 1996 as part of the ongoing efforts to address revitalization and
historic preservation in downtown Hyannis. The HHDC promotes the
preservation of the unique historic character of downtown Hyannis and
Hyannis Inner Harbor. The Commission strives to create a desirable place to
live, work and enjoy through the preservation, maintenance and improvement
of historic vernacular.
