FAQ

Remodeling in Concord & Clayton: questions

How long does an ADU take?

Typically 7–13 months from the first design meeting for a detached or attached ADU, 6–10 months for a garage conversion and 4–7 months for a junior ADU. Plan-check time depends on the building department, so we confirm current timing for your address when we apply and put both phases on a written schedule.

What kinds of projects do you take on in Concord and Clayton?

Kitchens, bathrooms, whole-home remodels, additions, second stories, ADUs and garage conversions, with exterior work as part of larger projects. Most projects fall in the $30K–$325K range; second stories and whole-home remodels usually cost more, as the project cards above show. We don't take on repairs or paint- or flooring-only jobs.
