This 320 sq ft studio ADU in the San Fernando Valley is a great example of how much functionality you can pack into a small footprint when the design and execution are done right. Built by NeoBuilders, this Van Nuys garage conversion transforms an underused space into a fully independent living unit with a full kitchen, a spacious bathroom, dedicated sleeping area, and seamless indoor–outdoor access.
Garage conversions continue to be one of the most efficient ADU options in the San Fernando Valley. They typically cost less than ground-up construction, move through permitting faster, and make use of an existing structure, without sacrificing comfort or design.

Interior Finishes That Elevate the Space
Flooring, Doors, and Light
One of the first things you notice when stepping into this ADU is the herringbone solid wood flooring. In a small space, floor pattern matters more than people realize. The herringbone layout adds visual movement, which helps the studio feel wider and more dynamic without adding square footage. Solid wood also brings warmth and durability, which is important for long-term use, whether this ADU is rented or used by family.
The solid wood front door does double duty. Beyond aesthetics, it provides better sound control and insulation than hollow-core alternatives, helping the unit feel private and substantial. Natural light plays a huge role as well. A sliding glass door opens directly to the patio, creating a strong indoor–outdoor connection that makes the ADU feel larger. Carefully placed windows, including a casement window in front of the sink, bring in daylight and allow for cross-ventilation without sacrificing privacy.
Kitchen Design: Fully Functional in 320 Sq Ft
With 10 linear feet, the kitchen layout prioritizes storage and workflow while keeping everything within reach. Appliance choices strike a balance between size and performance, including a 24-inch refrigerator, an 18-inch dishwasher, and a compact oven with a microwave hood.
The glossy espresso marbled countertops paired with offset textured backsplash tiles add depth and contrast, elevating the kitchen well beyond what you’d expect in a garage conversion. Undercabinet lighting and integrated shelf lighting improve visibility for cooking while adding ambient light in the evenings. A custom-built pantry, dedicated coffee station, and a four-seat dining table round out a kitchen that feels complete, not scaled back.
Bathroom Design: Maximizing a 9x6 Layout
At just 9 by 6 feet, this bathroom shows how smart planning can make a compact layout feel comfortable. A pocket door eliminates swing clearance, freeing up valuable floor space. The shower features full-height vertical tile in a soft baby blue, drawing the eye upward and making the room feel taller.
A frameless glass shower enclosure keeps sightlines open, while a lighted niche adds both function and a subtle design detail. The vanity combines dark cabinetry with a clean white countertop and brushed brass hardware, tying the space back to the finishes used throughout this Van Nuys garage conversion. A stacked washer and dryer fits neatly into the layout, with extra storage above, an essential feature for long-term livability.
Sleeping Nook and Storage Solutions
Rather than leaving the studio completely open, this ADU incorporates a dedicated sleeping nook that creates a sense of separation without closing the space off. Dark wainscoting visually anchors the sleeping area and helps define it as its own zone, making the layout feel intentional rather than improvised.
Closet placement was carefully considered to maximize storage without interrupting circulation. By keeping storage vertical and built-in where possible, the design avoids clutter and preserves usable floor space, one of the biggest challenges in any studio ADU.
A Nod to the Original Home’s Design
While the focus of this project was creating a highly functional studio ADU, care was taken to respect the character of the original home. The existing house was designed and built by William Mellenthin, whose ranch-style homes helped shape much of the San Fernando Valley. One of his signature design elements, the birdhouse-style cupola, was intentionally preserved during the garage conversion.
Rather than stripping the structure of its original charm, the ADU was designed to blend seamlessly with the main home. Exterior materials, proportions, and rooflines were carefully considered so the new living space feels like a natural extension of the property, not an afterthought. This approach allows the ADU to meet modern living needs while maintaining architectural consistency and curb appeal.
FAQ: Van Nuys Garage Conversion ADU
Can you convert a garage into an ADU in Los Angeles?Yes. Garage conversions are one of the most common ADU types in LA because they use an existing structure, which typically means lower cost and faster permitting than a ground-up build.
Do you have to replace parking when converting a garage to an ADU?No. Under California law, homeowners are not required to replace off-street parking lost from a garage conversion. This has been the case statewide since 2020.
How much does it cost to convert a garage into an ADU?Garage conversions start at about $120,000. Garage conversions generally cost less per square foot than new construction since the foundation, framing, and roof already exist. Final cost still depends on plumbing runs, finishes, and whether structural or electrical upgrades are needed.
How big can a garage conversion ADU be? Size depends on the existing garage footprint, but most garage conversions in LA fall between 300–500 sq ft. Garage conversions also qualify for ministerial approval under state law, meaning cities must approve them quickly if they meet basic state standards.
Can a garage conversion have a full kitchen and bathroom? Yes. A garage conversion ADU is treated as a full accessory dwelling unit, so it can include a complete kitchen and bathroom, the same as any other ADU.
Do garage conversion ADUs need their own separate entrance? Yes, garage conversion ADUs are required to have an independent entrance separate from the main house, along with their own utilities in most cases.
Is a garage conversion a good option for rental income? Yes. Because garage conversions are less expensive to build than detached ADUs, they often reach positive cash flow faster, making them a common choice for homeowners focused on rental income.
How long does it take to build a garage conversion ADU?A garage conversion can take anywhere from three months to one year depending on the condition of the garage and if demolition is necessary. Garage conversions typically move faster than ground-up ADUs since they qualify for ministerial approval and use the existing structure, which cuts down both permitting and construction time.
A Thoughtful Garage Conversion ADU in Van Nuys
Garage conversions remain one of the most practical ADU options in the San Fernando Valley, especially for homeowners looking to save on construction costs while speeding up the timeline. When done correctly, they can feel just as intentional and polished as a ground-up build.
