A Downtown Residence With Full-Service Convenience

The Ten Ten Mass condominium places residents at the intersection of Penn Quarter, Mount Vernon Triangle, and the broader downtown NW corridor — a location that consolidates transit, dining, and daily commerce into a walkable radius.

Unit 809 is an eighth-floor one-bedroom residence measuring 873 square feet, a notably generous footprint for a one-bedroom in this submarket. The building, constructed in 2004, delivers the infrastructure of a full-service condominium: pool, custodial services, common area maintenance, and a reserve fund structure that signals long-term building stewardship.

On-site rental parking addresses one of the more persistent friction points for downtown DC condo ownership. The HOA’s inclusion of water, sewer, trash, and snow removal further simplifies the cost-of-ownership picture for a buyer evaluating total monthly outlay.

The $480,000 price point positions this residence competitively within the downtown NW one-bedroom market, particularly given the square footage and the depth of HOA coverage relative to comparable buildings in the corridor.

The Building
Ten Ten Mass is a full-service condominium completed in 2004, situated on Massachusetts Avenue NW in the Mount Vernon Triangle corridor. The building offers pool access, custodial services, and a managed reserve fund — amenities that distinguish it from smaller boutique buildings in the immediate area.
The Residence
Unit 809 occupies the eighth floor and delivers 873 square feet in a one-bedroom, one-bath configuration. That square footage is meaningfully above the median for one-bedroom condos in this part of downtown NW, providing proportional living and dining areas that smaller units in comparable buildings cannot match.
Ownership Costs
The HOA structure covers water, sewer, trash, snow removal, pool, insurance, and reserve funds — a comprehensive package that reduces the variable cost burden on the owner. On-site rental parking is available separately, a practical advantage in a neighborhood where street parking is limited and garage rates are high.
The Location
Massachusetts Avenue NW connects this address to the broader downtown grid, with Penn Quarter, Chinatown, and the Convention Center all within close reach. Multiple Metro lines serve the area, and the density of retail, dining, and services in the surrounding blocks supports a car-optional lifestyle for most daily needs.

Frequently Asked Questions About This Property

Key details about the residence, building, and location to help you evaluate this opportunity.

The HOA at Ten Ten Mass covers common area maintenance, custodial services, insurance, lawn maintenance, management, pool access, reserve funds, sewer, snow removal, trash, and water. This is a comprehensive package that reduces the number of separate utility and service accounts an owner needs to manage. Buyers should confirm the current monthly fee amount directly with the building’s management company.
On-site rental parking is available at the building, though it is not deeded with the unit. Buyers interested in securing a parking space should inquire about current availability and monthly rental rates through the building’s management office. This is a meaningful convenience in a neighborhood where off-site parking options are limited and costly.
At 873 square feet, Unit 809 is notably spacious relative to the typical one-bedroom condo in the downtown NW and Penn Quarter corridor, where many comparable units fall in the 650-to-800-square-foot range. The additional square footage translates into more proportional living and dining areas. Buyers evaluating this unit against alternatives should factor floor plan usability alongside raw square footage.
The building is close to several Metro stations, including Gallery Place-Chinatown on the Red, Yellow, and Green Lines, Archives-Navy Memorial on the Yellow and Green Lines, and Judiciary Square on the Red Line. This proximity to multiple lines provides routing flexibility for commuters traveling to various parts of the region. Metrobus service on Massachusetts Avenue NW adds further transit options.
Ten Ten Mass was built in 2004, placing it among the mid-2000s wave of full-service condominium development in the downtown NW corridor. Buildings of this vintage typically feature concrete and steel construction, professional management structures, and established reserve funds. Buyers should review the most recent reserve fund study and budget documents as part of their due diligence.
The building sits in the Mount Vernon Triangle neighborhood of NW Washington, bordered by Penn Quarter to the west and the Convention Center area to the north. The surrounding blocks offer a dense mix of dining, retail, and services, and the address connects easily to the broader downtown grid. The neighborhood’s central position makes it one of the more transit-accessible locations in the city.
The address supports a car-optional lifestyle for most daily needs, given its proximity to multiple Metro lines, Metrobus routes, and the walkable concentration of retail and services in the surrounding blocks.
