The owner of a hotel in Green Valley is signaling interest in building apartments.
Capital Second Investments, which owns Hotel Pentagon at 2480 S. Glebe Road near I-395, has filed a conceptual site plan application envisioning a 467-unit apartment building and 36 townhouses. Some entities take this step before filing a formal site plan application to get early feedback on the feasibility of their proposal.
The concept from Capital Second Investments situates the housing on a site that currently houses the Hotel Pentagon — which used to be a Best Western, and consists of a standalone structure and a trio of long, two-story buildings — as well as the Comfort Inn Pentagon City, a single tower next door.
Both hotels are listed at 2480 S. Glebe Road, which is at the corner of 24th Road S. and S. Glebe Road, surrounded by I-395, the Lomax AME Zion Church, some auto body shops and two apartment complexes.
Capital Second Investments proposes to fill the 467-unit building with:
- 99 “junior 1-bedroom” units, which are studios with a small space that can be separated off
- 191 1-bedroom units
- 59 1-bedroom units with dens
- 118 2-bedroom units
- 608 underground parking spaces
- A pool and an amenity deck
Across a tree-lined path from the complex would be two rows of stacked townhomes, with a typical floor area of 2,425 square feet, and parking.

Conceptual site plan applications are preliminary by nature — a step some take before submitting a formal site plan application, which would be reviewed by staff and Arlington County’s various citizen committees.
“This application, and its administrative review process, is intended to provide guidance to prospective applicants in the preparation of land use development applications,” the application says.
Prior to becoming the Hotel Pentagon, the Best Western on S. Glebe Road was the scene of prostitution-related run-ins with law enforcement. In one publicized case, a man who forced a 16-year-old girl into prostitution at the motel later pleaded guilty to sex trafficking a minor.
