ADU house plans (Accessory Dwelling Unit) give you a smart way to add a separate living space to your existing home.
These compact designs – often called granny flats, guest houses, or detached in-law suites – provide independent quarters that add tremendous flexibility to virtually any home site.
Our collection of ADUs includes everything from efficient studios to complete cottages with multiple bedrooms, each carefully designed to maximize space within their more smaller footprints.
Many homeowners build ADUs specifically to house family members who need their own place while staying on-site at your place.
Whether it's aging parents, growing or adult children, or other relatives, these highly useful secondary dwellings create the perfect balance of living space for all and independence.
The objective is to give your relatives privacy and autonomy while keeping them within touching distance of your main home.
With complete fitted kitchens, private bathrooms, and comfortable bedroom areas, your loved ones can enjoy independence without the isolation of living across town.
ADU plans offer excellent potential as rental units. Given today's tight housing market with high rental demand and yields, adding independent compact homes to your property can command impressive rent relative to their construction costs.
Many homeowners find their investment pays for itself faster than expected while simultaneously boosting overall property appeal. Locating these units on your existing land makes them particularly attractive for those seeking to generate income without purchasing additional real estate.
Our plans deliver thoughtful layouts that make a huge impact for small dwellings.
By leveraging some intelligent design techniques, ADU properties punch above their weight on comfort.
How? The first factor is that open configurations are great at eliminating wasted areas, while built-in storage keeps essentials organized and accessible. Well-positioned multi-purpose rooms – e.g., kitchen-diners – expand functionality without increasing raw size, and careful window placement floods interiors with natural light.
One of the greatest strengths of these house plans is their adaptability over time. The space that begins as housing for aging parents might later serve as a home office, creative studio, or rental unit as your life changes and evolves.
Some clients initially use an ADU for rental income, then transition it to family housing as children return from college or parents need care. Others use the space for home-based businesses before converting it to living area or guest quarters, and then rent it out.
This remarkable flexibility makes ADUs a forward-thinking investment that continues to provide value as your circumstances change.
Of course, your ADU’s aesthetic matters. It’s not merely a bolt-on for your property – it shouldn't look like an afterthought. Luckily, our collection covers an eclectic range of architectural styles, from traditional to modern.
Many clients choose a plan that complements their existing home for a cohesive, continuous look across the entire site. Our design team can help customize exterior details, window styles, and finishes to create visual harmony between structures while still giving your ADU its own distinct character.
