The Chaloner House is a large Federal-style building situated on a rise overlooking the waterfront in the Washington County town of Lubec. Erected in stages by about 1818, the building exhibits an unusual plan featuring two primary entrances and three formal front rooms on each floor which are backed by a series of small secondary rooms under a salt-box addition. Although somewhat altered over the years, the primary rooms contain notable examples of Federal style woodworking, and the massing of the building is distinctive in a town that contains very little early nineteenth century architecture. The building, which has been traditionally described as an inn, was owned by William Chaloner between 1817 and 1834, and census records suggest the presence of lodgers some of whom were foreigners. The Chaloner House was listed in the National Register of Historic Places at the local level of significance as a relatively rare example of an early 19th century lodging facility in the Washington County region.
