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 San Ramon

We offer kitchen and bathroom remodeling, ADUs and outdoor living projects in San Ramon.

The local housing includes 1980s through 2010s planned communities, many with original builder finishes. Newer lots can be compact and may require HOA architectural review alongside city permits. We consider both during design.

We serve San Ramon, including Dougherty Valley, Windemere, Bishop Ranch area and Gale Ranch. Project planning here accounts for planned-community lots where HOA architectural review runs alongside city permits. We assess foundations, drainage and space on the lot when planning an addition or detached unit.

Frequently asked questions

Are ADUs legal in San Ramon?

Yes — ADUs are legal in San Ramon. California law requires cities to allow ADUs on most residential lots, and San Ramon 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.
