Arbor Hill Historic District–Ten Broeck Triangle
In 1975 several residents of the Ten Broeck Triangle formed the Arbor Hill Concerned Citizens Association (AHCCA) to lobby the city for improvements in neighborhood services. Many of them lived in the surviving townhouses, which they had often restored themselves. They saw gentrification as the key to revitalizing the neighborhood, due to its proximity to downtown Albany and the growing service-sector jobs there. To further this goal, they worked with preservationists to have the triangle recognized as a historic district. That area was duly listed on the Register in 1978 under that name.

In the new century, the neighborhood's growth slowed down as it was nearly built out. A few new houses were built, mostly architecturally sympathetic to their surroundings but experimenting slightly with their materials, such as local architect William Lee Woollett's brick houses with marble trim at 43 and 45 Ten Broeck Street in 1900. At 66 First Street another brick and stone house went up, meshing with its much older neighbors.
