High Street Historic District
Also known as: See Also:Grubb Mansion
Why it's listed
Along both sides of High Street in Pottstown, a lineal district of mansions and substantial houses built between 1860 and 1941 follows the main east-west road from Adams Street to Rosedale Drive. The homes were built for industrialists, merchants and managers during the borough's industrial boom, and most were erected in a concentration between 1875 and 1928. Architectural styles include Queen Anne, American Four Square, Victorian Gothic, Italianate and Georgian Revival, with some houses ranging from 2 to 3-1/2 stories and lots up to 100 feet wide. Large twin houses were designed to look like single mansions. The street was widened and leveled for a trolley line in 1893, and a roughly 2000-foot rusticated limestone retaining wall was built along its north side. The district is regarded as the finest collection of its kind in Pottstown, and its uniform streetscape of late Victorian and early twentieth-century residences reflects the town's peak period of growth.
Significance in brief: The district contains many of Pottstown's first and best examples of country homes and mansions of industrialists, merchants and managers. It preserves a residential environment that developed during the period when Pottstown was at the height of its industrial boom and greatest expansion. The nomination argues that no other concentration in the borough matches its quality, stylishness, integrity and size.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
