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 Fairfield
We offer remodeling, painting and concrete services for Fairfield homes.
The local housing includes 1960s–80s ranch tracts with newer development toward Green Valley. 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 Fairfield, including Green Valley, Cordelia, Rancho Solano and Village 5. Project planning here accounts for the Cordelia wind gap, which is hard on exterior paint and roofing. We assess foundations, drainage and space on the lot when planning an addition or detached unit.

Permits for work in Fairfield go through the City of Fairfield Building Division.

Frequently asked questions
Are ADUs legal in Fairfield?
Yes — ADUs are legal in Fairfield. California law requires cities to allow ADUs on most residential lots, and Fairfield 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.
