Add an ADU to your property, without the guesswork.
Kaizen designs, permits, and builds your accessory dwelling unit as one accountable team, so you get a finished, move-in-ready ADU without juggling designers, the city, and a crew of contractors yourself.
Can you build an ADU? Most likely, yes.
California makes it easier than ever to add an ADU to a single-family property, and most lots qualify. The real questions are what size makes sense, what it will cost, and how to get it done without the stress. That is what we handle for you, starting with a free check of your specific lot.
Your ADU, in five clear steps.
Free consultation and lot check
We review your property, your goals, and whether an ADU makes sense. No cost, no obligation.
A few daysFeasibility, design, and a clear quote
We confirm the size and layout, handle the design, and give you a clear price and timeline before you commit anything.
A few weeksPermits and approvals, handled for you
We prepare and submit the plans and manage the city back-and-forth, so you do not have to.
Varies by cityBuild
Your ADU is built by our team, with a 3D-printed option through 4DIFY for faster, more resilient construction, or a vetted general contractor.
