Materials, cabinetry, lighting, surfaces and fixtures, plus complete interior build-outs.

Choosing the right ADU

Common questions

What is the difference between an ADU and a junior ADU?

An ADU is a separate unit on the lot, detached or attached. A junior ADU (JADU) is a unit of up to 500 sq ft created within the walls of an existing or proposed single-family home. A lot can often include both.

Which ADU type is right for my property?

It depends on your yard space, the condition of your garage, your goals and your budget. The free feasibility check compares the options for your exact address.

Do you handle the permits?

Yes. We prepare and submit the permit package, respond to plan-check comments and schedule the inspections.

Can you also remodel the main house?

Yes. We handle high-end remodels, interior build-outs and finishes with the same structured approach, and can plan them together with your ADU.
