ADUs, done for you

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.

The straight answer

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.

How it works

Your ADU, in five clear steps.

01

Free consultation and lot check

We review your property, your goals, and whether an ADU makes sense. No cost, no obligation.

A few days
02

Feasibility, 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 weeks
03

Permits 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 city
04

Build

Your ADU is built by our team, with a 3D-printed option through 4DIFY for faster, more resilient construction, or a vetted general contractor.

FAQ

Questions homeowners ask.

Do I qualify?

Most California single-family lots do. We confirm yours for free in the consultation.

Can I rent it out?

Yes. ADUs can be rented for extra income, or used for family.

How much does it cost?

See the starting price above. You get a firm quote after the free lot check.

How long does it take?

Usually about 6 to 12 months, consultation to move-in.

Do you handle permits?

Yes. We prepare, submit, and manage approvals for you.

What is a 3D-printed ADU?

A concrete shell printed by 4DIFY, which can be faster and more resilient than conventional framing, and can help lower insurance and energy costs. It is an option, not a requirement.

What areas do you serve?

Homeowners within roughly 150 miles of the Sacramento region. Not sure if that covers you? Ask, the consultation is free.
