Home Additions & ADUs
in Discovery Bay, CA
Looking for home additions & adus in Discovery Bay? AZ Elevated Builders is a family-run, CA-licensed general contractor based in Brentwood — close enough to Discovery Bay to walk your project this week, and experienced enough to build it right the first time.
A good addition reads as if it was always there — the rooflines continue, the windows match, the proportions hold. We design and build primary-suite additions, kitchen expansions, family rooms and second-story pop-ups that blend into the original house instead of announcing themselves.
Accessory dwelling units are the best investment in California residential construction right now: rental income, space for family, long-term property value. We handle feasibility, the state's evolving ADU rules, local permitting and utilities through final inspection.
Waterfront living puts extra demands on a house. We build and remodel around docks, decks and Delta weather in Discovery Bay.

Frequently asked questions
Are ADUs 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 give you the real timeline up front and keep you updated weekly.
