One of Tenleytown’s workhorse office buildings is quietly up for grabs, and a future deal could rewrite a busy stretch of Wisconsin Avenue.
Douglas Development has put its multi-tenant building at 4001 Brandywine St. NW on the market as a redevelopment play, with the potential to significantly reshape the corner. Today, the property houses a mix of neighborhood services, from childcare to medical and fitness suites, and any major overhaul would ripple through nearby retail, transit access, and school drop-off traffic. If a buyer decides to chase zoning changes and new construction, neighbors should be prepared for a process that could stretch from months into years.
As reported by the Washington Business Journal, Douglas Development is actively marketing 4001 Brandywine this month and pitching the site for a substantial redevelopment. The outlet notes that a proposed upzoning could more than double the site’s allowable square footage, and that brokers have begun circulating the listing to prospective buyers and developers.
What’s on the block
Commercial real estate listings describe the property as roughly 68,310 square feet on about 0.68 acres, with ground-floor retail and surface parking, per CommercialCafe. The site also includes neighborhood-serving uses such as a licensed child development center, according to a city facility listing from the D.C. Office of the State Superintendent of Education, along with medical and therapy suites that draw nearby residents and students from Jackson-Reed High School.
What a buyer could build
The Tenleytown Public Life Study sketches out a future for the corridor that includes targeted infill and the possibility of taller, mixed-use buildings in select locations, according to the DC Office of Planning. To go beyond what current zoning allows, a new owner would likely pursue a rezoning or a Planned Unit Development, tools the city uses to grant extra height and density in exchange for public benefits such as affordable housing or streetscape improvements.
Neighbors and approvals
Tenleytown neighborhood advocates have a track record of scrutinizing bigger buildings. They have previously pushed back on projects that increase height without what they see as adequate mitigation, citing worries over shadows, traffic, and parking impacts. Those concerns are documented in a Tenleytown Neighbors Association filing in the records of ANC 3E. In practice, that local oversight means developers typically start conversations early with the Advisory Neighborhood Commission and the Office of Planning to hash out potential mitigations and community benefits before any formal zoning cases appear.
Developer background and next steps
Douglas Development is a long-standing player in D.C. real estate and highlights a sizable local portfolio on Douglas Development. For this site, interested buyers and nearby residents will want to keep an eye on formal case filings with the D.C. Zoning Commission and the Office of Planning, and both bodies publish case dockets and supporting materials online for public review.
Brokers are expected to shop the offering over the summer, with early redevelopment concepts likely surfacing first in marketing decks and teaser materials before anything official hits the city’s portals. We will be watching public dockets and ANC notices as the sale process unfolds.
