Who offers home additions & adus in Discovery Bay, CA?
AZ Elevated Builders provides home additions & adus in Discovery Bay, California. We are a family-run, licensed and insured general contractor based in Brentwood, serving Discovery Bay and the surrounding Contra Costa County area. Estimates are free, every trade on our crew has 15+ years of experience, and all work carries a written warranty of up to five years. We speak English and Spanish. Call (925) 812-3150.
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 Discovery Bay
Waterfront living puts extra demands on a house. We build and remodel around docks, decks and Delta weather in Discovery Bay.
The local housing includes 1980s through 2000s waterfront and golf-course homes. Additions near the Delta need attention to foundations and drainage because of soil conditions and the water table. We assess these during feasibility planning.
We serve Discovery Bay, including Discovery Bay Country Club, Ravenswood, Lakeshore and The Willows. Project planning here accounts for levee-adjacent lots, a high water table and constant Delta wind and humidity. We assess foundations, drainage and space on the lot when planning an addition or detached unit.
Permits and inspections in Discovery Bay
Permits for work in Discovery Bay go through Contra Costa County Building Inspection, since Discovery Bay is unincorporated. 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 Discovery Bay?
Yes — ADUs are legal in Discovery Bay. California law requires cities to allow ADUs on most residential lots, and Discovery Bay 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.
