ADU Basement With Kitchen - 667 Sq Ft , Washington, DC
Sage green cabinetry, a bold bathroom with black grid shower doors, and a hidden office tucked beneath the stairs—this 667 square foot ADU basement packs serious functionality into every corner. Located in Washington, DC, the project transforms an underused lower level into a fully independent living space complete with kitchen, bathroom, and flexible areas for work and relaxation.
What makes this renovation stand out? The homeowners wanted more than storage or a spare room. They needed a legitimate living space that could function as a rental unit, guest quarters, or eventually a place for aging parents. Every design decision supports that goal, from the full-size appliances to the thoughtful ambient lighting throughout.
DC row homes and historic properties often present unique challenges when it comes to basement finishing in Washington. Ceiling heights, existing mechanicals, and local regulations all factor into what's possible. Here, the team maximized every inch while maintaining the open, airy feel that makes the space livable rather than cramped.
The under-stairs office nook deserves special mention. Rather than wasting that awkward triangular space, it became a compact workstation with built-in shelving. Smart? Absolutely. And it's exactly the kind of creative solution that separates a thoughtful renovation from a basic finish.

What Makes This Washington DC Basement Special
Step past the main living area and the kitchen immediately commands attention. Sage green cabinets bring warmth and personality—a refreshing departure from the all-white kitchens that dominate Pinterest boards. Stainless steel appliances handle serious cooking, not just reheating leftovers. Generous counter space means meal prep doesn't require constant shuffling of cutting boards and mixing bowls.
Building a full kitchen in a basement ADU requires navigating DC permits and inspections for plumbing, electrical, and egress requirements. The scope here included proper ventilation, code-compliant electrical circuits for appliances, and drainage tied into existing systems. Getting these details right separates a legal, rentable ADU from a finished basement that can't be used as intended.
The bathroom makes a statement with its black grid shower doors—a design choice that photographs beautifully but also serves practical purposes. Grid patterns hide water spots better than frameless glass while adding architectural interest. Custom tile work throughout and carefully selected fixtures create that spa-like quality without veering into excessive luxury pricing.
Creating functional basement apartments and ADUs demands expertise in mechanical systems, moisture management, and space planning. This project demonstrates how proper execution transforms 667 square feet from cramped afterthought into genuine living quarters. Open-concept design keeps sightlines clear while durable flooring handles the traffic that comes with daily use.
Design Elements and Layout
Neutral tones anchor the palette throughout the living areas, allowing accent pieces and furniture to define the personality. This approach gives future occupants—whether renters or family members—flexibility to make the space their own. Flooring choices prioritize durability without sacrificing aesthetics, standing up to foot traffic while complementing the overall design.
Storage solutions here deserve attention. Open shelving displays items worth showing while hidden compartments handle everything else. Custom built-ins maximize wall space without making rooms feel cluttered. It's an approach gaining popularity in basement remodeling throughout Georgetown and surrounding DC neighborhoods where square footage comes at a premium.
The kitchen layout follows principles common in well-designed basement kitchens—efficient workflow, adequate counter space, and appliances positioned for practical daily use. Ambient lighting layers throughout the lower level create warmth and eliminate the cave-like feeling that plagues poorly planned basements. Recessed fixtures provide general illumination while accent lighting highlights architectural details and cabinetry.
That under-stairs office nook exemplifies the creative thinking required for smaller footprints. Rather than accepting dead space, the design incorporates a functional workstation with integrated storage. It's private enough for video calls yet connected to the main living area.
The Transformation Impact
Converting 667 square feet of basement into a legitimate ADU fundamentally changes how this DC home functions. Suddenly there's rental income potential, space for extended family visits, or a private retreat for adult children. The return extends beyond monthly rent checks—it's about flexibility and options that didn't exist before.
Every element works together: the full kitchen enables independent living, the bathroom provides privacy, and the living areas offer genuine comfort. This isn't a basement with a bed tucked in the corner. It's a proper residence that happens to be below grade.
For homeowners considering similar projects in DC's historic neighborhoods, understanding construction requirements for older properties matters significantly. Many row homes and period properties need specialized approaches, which is why expertise in historic home basement remodeling in Washington DC proves valuable. The right team navigates structural considerations, preservation requirements, and modern building codes to deliver results like this ADU transformation.
