According to the National Park Service:

<blockquote>
The Mendham Historic District consists of 140 properties, generally well preserved, that illustrate the history of the village from its eighteenth century founding through its 1906 incorporation as a borough, and into the first third of this century when infill building completed development within the historic bounds of the village. The District covers the central crossroads of the village, and extends as far as the area nineteenth century maps illustrate as "Mendham, P.O.", the village core containing the post office. The conjunction of religious, residential, and commercial buildings that have established Mendham's village character are well preserved today.<ref name=NPSnom/>
