Endangered Buildings Initiative

Preservationists are often called to rally for buildings at the eleventh hour, when the wrecking ball is in place or after the development deal has been approved.

Endangered Buildings Initiative is an attempt to identify buildings at risk while there may still be time to save them.

Our List

The Conservancy surveyed landmarks and historic districts throughout the City in the summer of 2000 and has periodically updated the findings. We ranked the 20,000 plus buildings by degree of deterioration visible from the street. “Red” buildings, the most deteriorated, are now online.

Because new historic districts have been and are being created, and because conditions change, no list like ours is ever complete or comprehensive. We need your input. So Endangered Buildings Initiative serves as a searchable, interactive database.

Your Input

Tell us if you know a building has improved or declined. And suggest additional listings. Aside from its visible condition, a building may be endangered by an impending change of ownership or pressure to tear down the building for a larger development.

Just click “Suggest A Listing“ to find the form.

The Impact

Your feedback will help the Conservancy as we work with public officials and preservationists in immediate neighborhoods to devise strategies for saving and reusing these historic sites.
