Detached ADU guest house with pool at dusk

We design and build primary-suite additions, kitchen expansions, family rooms and second-story additions. Rooflines, windows and finishes are planned to work with the existing house.

An ADU can provide space for family or a rental unit. We handle feasibility, California's ADU requirements, local permitting and utilities through final inspection.

Planning your project in Concord

We offer whole-home remodeling and additions for Concord's ranch and split-level homes.

The local housing includes post-war 1950s and 60s ranch and split-level tracts. Some post-war properties have space for an addition or ADU. We assess the lot and any existing garage during the feasibility review.

We serve Concord, including Todos Santos, Dana Estates, Ygnacio Valley and Clayton Valley. Project planning here accounts for flat valley lots with expansive clay and hot inland summers. We assess foundations, drainage and space on the lot when planning an addition or detached unit.

Permits and inspections in Concord

Permits for work in Concord go through the City of Concord Building Division. Additions and ADUs are the most review-heavy work we do — setbacks, lot coverage, utilities and California's ADU rules all get checked before a shovel moves. We handle the permit application and coordinate inspections.

Frequently asked questions

Are ADUs legal in Concord?

Yes — ADUs are legal in Concord. California law requires cities to allow ADUs on most residential lots, and Concord processes them under those state rules. We confirm setbacks, size limits and utility requirements for your specific parcel during the free feasibility visit.

What does an ADU cost to build?

It varies with size, site and finish level — a garage conversion is a different project than a detached new build. We price it in a written scope after walking your property, and financing options are available.

How long does an addition take?

Design and permitting typically run 2–4 months depending on the city; construction runs 3–6 months for most additions and detached ADUs. We provide a written schedule and keep you updated weekly.
