We manage every step from permits to keys-in-hand, and with our streamlined prefab + custom model, you’ll enjoy top-quality design without the builder headaches.
Standalone ADUs (Backyard Homes)
From sleek casitas with vaulted ceilings to timeless guest cottages, we design and build detached ADUs up to 1,200 sq. ft. — complete with full kitchens, bathrooms, and independent utilities. Perfect for multigenerational living, rental income, or boosting future resale value.
Prefabricated ADUs
Our prefabricated ADUs start at $189,000 and come with curated finish packages, optional upgrades, and faster build timelines. We handle everything — site preparation, foundation, utility connections, and local permits — delivering a stylish, turnkey solution from start to finish.
Garage Conversion ADUs (JADUs)
Transform unused garages into junior ADUs with efficient layouts, legal kitchenettes, and fully insulated interiors. Perfect for downsizing parents, dedicated home offices, or short-term rental opportunities.
Accessible & Aging-in-Place ADUs
Looking for accessibility? We build ADUs with ramps, wide doorways, roll-in showers, grab bars, comfort-height toilets, and open layouts — fully ADA-compliant and ideal for aging in place or caregiving needs.

Frequently Asked Questions
Prefab ADUs come with pre-designed layouts and limited customization, making them quicker to build and more budget-friendly. Custom ADUs are fully tailored to your preferences and property, but they typically require more time for design, permitting, and construction.
Luxury ADUs often include vaulted ceilings, high-end finishes, folding glass doors, smart climate control, and a full kitchen that matches the main home. These features create a guest house that feels like a seamless extension of your property rather than a secondary space.
Design and permitting usually take about 3 to 5 months, with construction adding another 4 to 6 months. Opting for a prefab model can cut both phases by roughly 30%.
Yes — prefab ADUs provide quicker construction timelines and more predictable costs. The trade-off is reduced flexibility in layouts, rooflines, and finishes compared to fully custom builds.
