How it works
From a model to your ADU
- 01
Pick a starting point
Choose the model closest to what you need: size, bedrooms and style. Starting from a layout saves time on the drawings.
- 02
We check your lot
We confirm it fits your lot and your city’s rules before you commit to anything.
- 03
Make it yours
Change finishes, colors, windows or the layout. We draw the final plans for your lot and take them through permits.
None of these fit? We also design ADUs from scratch. See how we build ADUs
Next step
Found one you like? See if it fits on your lot.
We review every request within 1 business day. If it’s a project we take on, we call you to talk through your lot, your city’s rules and a rough budget. There’s no cost to find out.
Or call (510) 453-0400, Monday to Friday, 9am to 5pm.
