1. Choose Your ADU
Once you submit your request, our team will review your property remotely to confirm it’s the right fit. Because every site is unique, pricing is shown as a range. After our review, we’ll provide a clear, site-specific estimate so you can move forward with confidence.
2. Site Visit
A project specialist will visit your property to confirm feasibility and find the perfect spot for your ADU.
3. Proposal Review
You’ll get a proposal with your site plan and installation estimate. Once you're ready to move forward, we get busy.
4. Project Kickoff
We get your permits approved. We handle design and permitting for you. The approval process varies by location.
5. Factory Assembly
When we are approved to build, assembly begins in our state-of-the-art factory. We build your ADU with meticulous attention to detail.
6. Site Prep
We prepare your site by laying a foundation and connecting utilities. The process varies by location.
7. Home Delivery, Literally
You’re ready for installation. Once your installation date is set, your ADU begins its journey from our factory to your home.

We ensure everything is perfect inside and out. Then, you get your keys!
OUR SERVICES

PERMITTING &
PROJECT MANAGEMENT
Our team handles permitting, approvals, and coordination with local building departments in your area. We keep your project compliant and on schedule so you never have to navigate complex regulations alone.

Your ADU is built off-site by our prefab partners and installed on-site by licensed contractors. Every project includes design, site prep, delivery, and installation. Your new space arrives on time, on budget, and built to last.
ROI CALCULATION
Upon request, we project your ADU’s rental income, value growth, and payback period based on your ADU size, local rates, and financing options. Whether you’re building for passive income, retirement planning, or multi-generational living, our ROI tools help you build smarter.

We educate homeowners on ADU-friendly loans, local grant programs, and flexible financing options through trusted lenders. You’ll understand exactly what you can afford and how to finance your ADU in a way that maximizes your long-term return.
