The Chalfont Historic District is listed on the National Register of Historic Places.
Chalfont is full of lovely Victorian houses, many of which are now occupied by businesses in the downtown district. These former residences are concentrated at the intersection of Butler Avenue and North Main Street, extending down North Main Street. East Butler Avenue leads to a more municipal section, where many of the buildings are vacant and add a degree of unsightliness to the otherwise quaint town. Further up the hill are Saint Jude School and Church, Brittany Farms and the Highlands.
According to the United States Census Bureau, the borough has a total area of 1.6 square miles (4.3 km²), all of it land.
