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.
North Ann Arbor Street Historic District
The North Ann Arbor Street Historic District consists of 22 homes and 11 barns and carriage houses, located along a single block of Ann Arbor Street. The houses were constructed from the 1870s through the first part of the 20th century, and are primarily fine vernacular versions of Gothic Revival, Colonial Revival and Queen Anne architecture. The district also contains two Italianate homes and one Bungalow which have had substantial facade alterations, rendering them less historically significant, and two single-story ranch homes. Most of the homes are two-story structures faced with wood.
