How to uncover the history of your NYC apartment building

When Brian Hartig and his husband first bought a brownstone in Bed-Stuy and set about the process of renovating it, almost immediately "things started falling out of the walls," he recalls.  "We were finding them under the floor boards." The "things," it turned out, were artifacts left behind by the families who had lived in the house before them.

"I had a regular curio cabinet full of objects by the time we were done," he says, including Victorian children's blocks from the 1890s, a shoe catalog, and an old receipt dating back to the 1910s. These random finds sparked Hartig’s interest in the history of his new home, and he started to research it in earnest, ultimately finding records showing that the property was farmland the 1700s and owned by Jacobus van de Water, mayor of New Amsterdam in 1673.

These days, Hartig does this kind of research for a living at his company, Brownstone Detectives, taking requests from clients who want to know more about their homes, doing the research for them, and putting it all into a book at the end of the process.  "Clients tell me what they want to know and I get to follow the clues….We’ve uncovered stories of Baseball Hall of Famers, murderers, Civil War heroes, unexplained fires, explosions, deceit, corruption, unrequited love, and much, much more."

Starting your own search

If you're interested in uncovering details about your own abode—from when it was built, to what your neighborhood used to look like, to who used to live there—the city has a surprising number of resources available for armchair history buffs.

"New York City easily has the most resources and accessible documentation," says Sarah Bean Apmann, Director of Research and Preservation for the Greenwich Village Society for Historic Preservation. "In researching a building one is bound to find at least some information on who built it, who lived in it, and/or what businesses may have occupied it."

As such, you hardly have to be a PhD-level researcher to dig up some valuable information. "Don't reinvent the wheel," advises Anthony W. Robins, architectural historian, former Director of Survey at the New York Landmarks Commission, and author most recently of “New York Art Deco: A Guide to Gotham’s Jazz Age Architecture.  (Robins also teaches a course on NYC building research each year at the Municipal Art Society -- his next is scheduled for September.)

It may be that someone has done the research on your building already and published it online. If you are lucky enough to live in a building or historic district that has received official landmarking status from the NYC Landmarks Preservation Commission, your work will have been done for you.  If your building has been landmarked, that will be indicated on the NYC Department of Buildings' Building Information Site (BIS) website. And if you're not sure whether you live in a historic district, there's a map you can consult here. 

If your building has made the cut, you will be able to find a detailed designation report on the LPC's Designation Reports page—and that may well provide all the information you need or want to know.

If your building is located in the catchment area of the Greenwich Village Society for Historic Preservation (roughly river to river from West 14th to Houston Street), check with their staff—they have done reports on buildings that may not have been formally landmarked. Or if you’re on the Upper West Side of Manhattan, go to Landmark West’s database—it’s quite thorough and easy to use.

If your building is on the National Register, you can get a copy of the historical report at "This can take some doing," warns Robins, who includes a how-to on his site, linked in the next section below.  

If the research on your building hasn’t already been done by someone else and you want to do your own detective work, we recommend that you begin with two excellent on-line sources:  “Who Lived in a House like This?” The New York Public Library's research tool and “Intro to Online Research Resources”  Robins’ website  tool. Though not as comprehensive, the GVSHP website has two pages (here and here) with good start-up tips, as well.

If your building does not fit into any of the above categories, here are some resources that Apmann suggests you try:



City Directories

Real Estate Records

  • The Real Estate Record and Guide was once the go-to guide for all things real estate in the city and it’s where you’ll find building permits and lots of other interesting real estate news (and ads that are lots of fun to read) dating from March 1868 to December 1922.
