Who offers home additions & adus in Mountain House, CA?
AZ Elevated Builders provides home additions & adus in Mountain House, California. We are a family-run, licensed and insured general contractor based in Brentwood, serving Mountain House and the surrounding San Joaquin 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 Mountain House
Our Mountain House services include kitchen remodeling, flooring, backyard projects and ADUs.
The local housing includes homes in a master-planned community built almost entirely since 2001. Newer lots can be compact and may require HOA architectural review alongside city permits. We consider both during design.
We serve Mountain House, including Questa, Bethany, Altamont and Wicklund. Project planning here accounts for newer construction in planned neighborhoods. We assess foundations, drainage and space on the lot when planning an addition or detached unit.
Permits and inspections in Mountain House
Permits for work in Mountain House go through the Town of Mountain House, which incorporated in 2024 and now runs its own building department. 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 Mountain House?
Yes — ADUs are legal in Mountain House. California law requires cities to allow ADUs on most residential lots, and Mountain House 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.
