With 2024 coming to an end, it’s clear that Accessory Dwelling Units (ADUs) have cemented their place as a means to greatly enhance of modern living. This year, the team at Maxable—a national leader in resources for building ADUs, Granny Flats, and Tiny Houses—has once again combed through a remarkable array of contenders to compile its much-anticipated annual list of America’s “10 Best” ADUs. These top selections aren’t just tiny homes; they’re big on innovation, offering a masterclass in design ingenuity, space optimization and aesthetics.
Why are ADUs so relevant right now? With housing costs soaring, many homeowners are looking for creative ways to maximize their property value while providing additional living options. ADUs offer a flexible, cost-effective way to generate rental income, accommodate aging family members, or even provide young adults with an independent living space—all without the need for costly relocations or massive new developments. And, as cities across the U.S. relax zoning laws and streamline permitting for these backyard beauties, the path to building an ADU has never been clearer.
For their part, each of these “10 Best” honorees redefine what’s possible in small-space living, blending creativity with functionality in ways that are as practical as they are stunning. Alongside detailed descriptions and expert insights from Maxable’s judges, the online showcase features multiple photos that spotlight the artistry behind each project. Now, the spotlight turns to the public. Voting is officially open to crown the standout “2024 ADU of the Year,” giving design enthusiasts and dreamers, alike, the chance to weigh in on which project deserves top honors.

Cascade ADU, Bay Area, CA
Size: 450 square feet
Beds: Studio
Baths: 1
Designed by Mayberry Workshop
Built by Owner/Build
An ADU that could be mistaken for a Parisian vacation home. This former garage got a true makeover to become a home any renter would be thrilled to live in. The original low sloped roof was removed and replaced with a sky high roof, making the space feel larger. Every inch of this ADU was built with intention, maximizing functionality and charm. The homeowners intend to use this space for passive rental income to supplement their future retirement plans. The team at Mayberry Workshop are no strangers to designing beautiful ADUs, so it’s no surprise to see them as a nominee once again.

Inkstone ADU, Denver, CO
Size: 1,504 square feet
Beds: 2
Baths: 1.5
Designed and Built by ADU4U Limited
A returning champion! ADU4U Limited was the builder behind 2022’s top voted ADU of the Year, and they’re back again with another show stopper. The black modern exterior is already turning heads as its second floor peeks from the backyard, but don’t let the darkness fool you. The interior of this ADU feels like a light luxury retreat. With sleek finishes, clever storage solutions, and an open layout that maximizes natural light, it’s a masterclass in modern design. The ADU is used for friends and family. All other times, it serves as a short term rental, and an income generator for the property owners. The downstairs provides a double garage for the property owners and a single bay garage for optional use by the ADU occupants. A yoga studio/home office with powder room gives the homeowners additional personal space, even if the ADU is occupied.

Golden Hour ADU, Berkeley, CA
Size: 408 square feet
Beds: 1
Baths: 1
Designed by Aaron Goldstein, RA
Built by McLean Construction
This 100-year-old, deteriorating, termite-ridden garage was begging for a transformation. This homeowner was already renting rooms in her main home as a way to build community and supplement her income. Planning ahead, she wanted to keep the community thriving but maintain privacy, so transforming the ADU into a stunning livable space was an obvious decision. A lot of people opt for grey interiors for versatility and ease, so when we see someone go outside of the box to add color and texture, we have to give kudos. The masterminds behind this garage conversion ADU opted for Douglas Fir wainscoting to bring warmth and coziness to the interior, crowned by clerestory windows at the peak of the vaulted ceilings to bring an incredible amount of light to the space.
Small touches like a murphy bed, bay window, and corner banquette make this ADU a truly multi-functional space.
Bonus points to the striking red door and curved detail of the pop-out, a true nod to mid-century style.

Another garage conversion takes a spot on the list. With a sleek, minimalist facade featuring arched black-framed glass doors and soft stucco finishes, the exterior is a perfect blend of modern and Mediterranean-inspired design. The private courtyard, flanked by lush greenery and a contemporary slatted fence, creates a peaceful entrance for homeowners and guests. The open-concept living area is filled with natural light, thanks to large sliding doors and a skylight overhead. Polished concrete floors and wood cabinetry bring texture and depth. This homeowner credits Maxable’s ADU educational content for helping them get on the right path to turn their vision into reality!

This charming one-bedroom ADU perfectly blends traditional design with a breezy, beachy feel. The project had some challenges (historical neighborhood, sewer distance, etc) but the end result was 100% worth it. Upon entering, you’re greeted by a cozy, well-appointed space where wood flooring neutrals and other natural textures create a relaxed coastal vibe. Classic details like shaker cabinetry lend a timeless touch, while sliding glass doors open to a small private outdoor area. At the other entrance, a pergola-covered entryway adds character and shade, setting the tone for this serene retreat.

The homeowners envisioned this ADU as a comfortable and accessible home for their elderly parent, allowing them to stay close to family while enjoying their own independent living space.

Summit ADU, San Diego, CA
Size: Junior ADU – 311 square feet, ADU – 342 square feet
Beds: Junior ADU – studio, ADU – 1
Baths: 1 each
Designed by Ruland Design Build
Built by Owner
This ADU pulls all out all the stops: garage conversion, above garage construction, and JADU all on a lot less than 4,000 sq ft. How? Let’s break it down. This unit originally was just a garage. Then it was converted into a JADU and reinforced for a second floor. Then they built a separate full-sized ADU on top of that. What a great use of space! The exterior features clean sleek lines and black railing and window accents, making this a modern spectacle that fits right into San Diego’s coastal landscape. The purpose behind project reminds us of another past ADU winner. The bottom JADU will be used for the homeowner’s 94-year old mother. It’s been designed with a larger bathroom for accessibility. The second floor ADU will serve as a rental for passive rental income. We love a project with versatility!
