The district occupies the southeastern portion of Albany's Arbor Hill neighborhood.
Its southern corner is Sweet Pilgrim Baptist Church at the junction of Ten Broeck Street and Clinton Avenue (part of U.S. Route 9), a block west of the Palace Theatre and across from Albany's Family Court building.
The district boundary, also the western boundary of the Broadway portion of the Clinton Avenue Historic District follows the rear lot lines of all the houses on the east side of the street, past St. Joseph's Church and Van Rensselaer Park north to Livingston Avenue.
There, the Ten Broeck Mansion, which gives its name to the Ten Broeck Triangle, the eastern third of the district, occupies a large parcel at the intersection's southwest corner.

The boundary then turns northwest along the south side of Livingston and follows it to North Swan Street, which it turns to follow south.
A hundred feet (30 m) south of the intersection, it takes in the properties on the west side and continues to do so for the next three blocks.
These include Bethany Baptist Church, St. Joseph's Youth Center and some commercial properties along the adjacent blocks next to them and the public basketball courts at the Second Street intersection.

Midway between First Street and Clinton the boundary turns southeast to follow the rear property line of the lots on First, again the boundary with the Clinton Avenue Historic District.
This line becomes Ludlow Alley shortly before North Hawk Street.
After a short southward jog to take in the two properties on that street north of Clinton, it returns to the alley and follows it back to Clinton at Ten Broeck.

The irregular polygon within this boundary includes six large blocks covering 34 acres (14 ha).
In addition to the streets already named, the entirety of St. Joseph's Terrace and Hall Place are within the district.
It has 220 contributing resources, with only two non-contributing modern properties.
One hundred of those properties are houses, primarily two- to three-story wood frame or brick structures built between the 1820s and the early 20th century.
The remainder are either small commercial buildings, institutional structures such as the three churches in the district.

Open space within the district includes a few vacant lots and parking lots.
Most are planned, such as Van Rensselaer Park, the neighboring space around the church known as St. Joseph's park, and the large parcel at the district's northeast corner where the Ten Broeck Mansion and its gardens (and former carriage house) are located.
Mature trees are abundant throughout.
Topographically the district rises almost a hundred feet (30 m) from its eastern and southern edges to level terrain along North Swan between Second and Third.
This reflects the ravines that existed there when Albany was first settled, later partially filled in to facilitate development, now the neighborhood of Sheridan Hollow, which separates Arbor Hill and the district from downtown Albany.

To the north of the district are newer housing projects built during the urban renewal projects of the 1960s and 1970s.
On the west of North Swan are similar neighborhoods but with newer, less coherent architecture (One building near the district, the Stephen and Harriet Myers House, is listed on the Register).
The Clinton Avenue Historic District on the south includes the city's densest concentration of 19th-century rowhouses, mostly brick.
To the east, downhill to North Pearl Street (New York State Route 32), are neighborhoods of mixed older and newer buildings and vacant lots, slowly being redeveloped, closer to the Hudson River.
