Dumbarton Court is a four-story Beaux-Arts cooperative completed in 1910 and composed of 27 residences on a compact, garden-oriented lot in Georgetown. The masonry façade and classical detailing reflect the building’s era; interiors frequently retain period elements such as crown moldings, arched doorways, original pine floors and decorative fireplaces alongside carefully executed modern renovations. Units are primarily two-bedroom (with some studios and combined units) and offer high ceilings, abundant windows on multiple exposures, and a mix of open and traditional floor plans. Common spaces include a staffed lobby, landscaped front and rear gardens with brick-and-stone paver grilling patio, secure storage rooms, a bike room and a shared laundry facility; two storage units are commonly conveyed with some apartments. Systems and services paid through the cooperative fee typically cover property taxes, water and heat, and on-site management or concierge-style support. Exterior amenities emphasize a quiet, well-lit streetscape with sidewalks, exterior lighting, hardscape, and maintained grounds; building access is elevator-served and fire escapes are provided. Parking in Georgetown is largely street-based; the building’s location offers very high walkability to Tudor Place, Dumbarton Oaks, Montrose Park and the C&O Canal, plus convenient transit and access to Georgetown’s retail and dining. The board maintains owner-occupancy rules, restricts investor purchases, and permits cats while generally prohibiting dogs; washer/dryer installation has been board-approved for in-unit hookups in many units.
