Red Hill Historic District
Also known as: Red Hill
The pin is a point inside the NPS boundary polygon, not a surveyed location.
Why it's listed
Red Hill is a small borough along Main Street (Route 29) in Montgomery County, Pennsylvania, whose core developed along the road laid out in 1735 as the Great Road to Philadelphia. Its growth came with the cigar industry of the 1880s to 1920s. Miller and Kline built a three-and-one-half-story brick cigar factory at 350 Main Street in the mid-1890s, and builders filled the gaps on either side with single and double brick millworkers' houses. S.C. Moyer's late-1880s factory on East Sixth Street drew further workers' housing, and William N. Trump built a rowhouse group on Adams Street by 1910. The district also keeps earlier buildings, including the Hillegassville Hotel of 1811 and the late Federal Josiah Hillegass House of 1847. Of its 185 buildings, 154 are contributing and 9 significant, and the district is valued for its surviving form and porches.
Significance in brief: The district is significant as a well-preserved late-nineteenth and early-twentieth century main street community whose growth was shaped by the cigar manufacturing industry, which transformed a sparsely settled village into a work and residence borough. It contains a unified collection of brick workers' housing, Pennsylvania German slate-shingled houses, Queen Anne and Victorian dwellings, and factories, along with earlier Hillegass family buildings of individual importance.

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).
