Rittenhouse Historic District
Why it's listed
Centered on Rittenhouse Square, the southwest square of William Penn's original city plan, this residential district spans roughly Walnut to Pine and 15th to 24th streets. Its streetscapes mix two-story rowhouses, red brick blocks of three- and four-story houses, stone-fronted mansions, and churches and schools, dating from the late eighteenth century onward. Developers such as John McCrea and Lemuel Coffin built many of the rows, while architects including John Notman, Frank Furness, George Hewitt, Theophilus Chandler, and Cope and Stewardson designed the principal houses and institutions. The district is regarded as a rare case of a central neighborhood that kept a continuous residential character across the nineteenth and twentieth centuries, with few large-scale rebuildings. Its architecture is unified by a restrained, Ruskinian approach to design. Later apartment towers, including Art Deco buildings from the 1920s and 1930s, were built on the square's edges, replacing earlier mansions.
Significance in brief: The nomination argues the district is a cohesive and largely intact neighborhood reflecting Philadelphia's architectural and social history from the late 18th century to the present. It holds a concentration of work by leading Philadelphia architects, from John Notman and Frank Furness to Cope and Stewardson, and its continuous residential character and restrained architectural taste allowed it to survive with few large-scale redevelopments.

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).
