Philadelphia Converts 85 Apartment Buildings in 7 Decades — 2nd-Most in U.S.


There’s something about old buildings that stand the test of time and rise from the ashes ready to face a new era. With residential conversion projects on the rise in the U.S., a recent study by RENTCafé showed that, since the 1950s, almost 2,000 old buildings had been transformed into apartment complexes — including 800 just last decade.

And, when it comes to the number of repurposed buildings, Philadelphia’s 85 conversions is ahead of New York City and Los Angeles and surpassed only by Chicago. Specifically, with nearly 11,300 new apartments created throughout the last seven decades, RENTCafé included Philadelphia among the top U.S. cities riding the adaptive reuse wave. The city’s rich history and major economical role as an industrial nexus since the 19th century make Philadelphia the perfect example of how conversion projects help preserve cultural value without disrupting the historic fabric of a community.

So, to find out more about how one of the oldest cities in the country manages to reinvent itself through adaptive reuse, we turned to Yardi Matrix data.

Conversions result in 85 new apartment buildings in Philly

Nowadays, Philadelphia boasts 85 converted apartment buildings (the second-largest number after Chicago’s 91) with 11,266 apartments, following only Chicago (14,167) and New York (18,488).

Philly experienced its first boom in the 1980s as conversion projects began to rise nationally throughout the latter half of the last century. During that decade, 17 buildings were repurposed after just 5 were converted in the 1970s. That’s a jump from 632 apartments converted in the 70s to 2,042 in the 80s. One of these buildings was a former leather tannery built in 1901 — better known today as Penn’s View Apartments — which still loves its exposed brick-interior walls.

Following the national trend, the most conversions in the last 70 years in Philly were completed last decade, when 3,765 new apartments were introduced as a result of 30 rehabilitation projects. Among them was the history-heavy Brownhill & Kramer Hosiery Mill, which was built in 1905 and is known today as The Chesterman Building.

Old factories, hotels office buildings most popular conversions in Philly

We’ve already covered mills and tanneries, so it’s no surprise that, given its vast inventory of industrial use buildings, Philadelphia favors repurposing vintage factories. In fact, of 85 successful conversion projects, 23 are the result of converted factories, such as The Chocolate Works, which was formerly home to the world-famous Wilbur Chocolate Company back in 1902. Moreover, the high number of such repurposed structures, including 1870s Oxford Mills, is a statement to the city’s rich industrial past.

However, Philly has also had its fair share of vintage hotels and open-space office buildings, which are also perfect for residential use. And, with 19 conversions, hotels are the second-most popular building type to convert into apartments in the city, followed by 15 repurposed office buildings. Examples include Griffin Center City, a former Beaux-Arts office space dating back to the 1890s, and The Arch, a mixed-use hotel and office building that still features the intricate, 1914-era terra cotta details that made it stand out back then, when it was known as the Wesley Building.

Philly’s oldest repurposed buildings are mostly vintage factories

Industrial structures make up most of the city’s oldest buildings to be repurposed, with 9 out of 10 entries consisting of mills, refineries, warehouses or manufacturing buildings. In particular, the oldest — and perhaps most well-known — is the historic Sugar Refinery. Dating back to 1792 and converted in the 1970s, this industrial-chic landmark is one of the earliest residential adaptations in town. And, squeezed between Philly’s oldest repurposed industrial gems is Lehigh Park, an 1880s hospital turned into affordable housing.

Philly’s most recent apartment conversion projects

Interestingly enough, two of the oldest buildings in town were actually some of the most recent conversions: Fairmount@Brewerytown — an 1891 warehouse — was converted in 2017, and Orinoka Mills Civic House, the result of a rehabilitating B.L. Solomon’s Sons, was an 1880 “dye house” and textile company.

Finally, the residential transition of a former paintbrush manufacturing facility from back in 1926 was completed in 2020. Today, Brush Factory Lofts come complete with industrial-sized windows and cozy exposed brick. Below are Philly’s latest conversion projects:

The most unusual apartment conversion projects in Philadelphia

Across the United States, unique buildings are just waiting for rehabilitation projects to uncover their hidden potential. Fortunately, in addition to spacious factories and convenient hotels, developers in Philadelphia have also seized upon the opportunity to bring life back to some of the city’s most interesting buildings, such as schools, stores and… an Armed Forces building.

For instance, one unusual choice to turn residential is The Metropolitan, which used to serve as the former Philadelphia YMCA Armed Forces Building and home to U.S. servicemen during World War II. The beautiful, late-1920s Art Deco building still showcases the original façade details.

Schools make for another interesting residential conversion. Specifically, the original Thaddeus Stevens School, built in 1926, is better known today as the gorgeous Mural Lofts. It was added to the National Register of Historic Places long before it even got the iconic “Common Threads” mural.

The Collins at Midtown Village is another great example of an unusual, non-residential building that works great as a repurposed apartment complex. Built in 1898, the former retail store still offers retail space to some of the most well-known brands available while also placing its residents close to the action.

Breathing new life into old architecture is not only a great way to pay homage to the history of a community, but it can also help meet demand and even sustainability needs. As 2020 draws to a close, we can’t help but wonder what kinds of adaptive reuse projects that cities like Philadelphia have in store for the next decade.


RENTCafé is a nationwide apartment search website that enables renters to easily find apartments and houses for rent throughout the United States. Apartment data was provided by our sister company, Yardi Matrix, a business development and asset management tool for brokers, sponsors, banks and equity sources underwriting investments in the multifamily, office, industrial and self-storage sectors.

Adaptive reuse refers to reusing an existing building for a purpose other than what it was originally intended for. The study is exclusively based on apartment data related to buildings containing 50 or more units. For the purpose of this study, certain building subcategories have been grouped into a general category that encompasses them. For example, manufacturing units, mills, or breweries fall under the Factory category.
