Accessory dwelling units • Livermore, California
ADU Contractor in Livermore, CA
Accessory dwelling units built as complete, livable homes — permitting and utilities through compact kitchens and baths.
An ADU is a small house, and small houses are unforgiving. Every inch of the plan has to work, and the utility connections, setbacks and code requirements have to be resolved before construction, not discovered during it.
We handle detached units and garage or interior conversions end to end: plans and permitting, foundation and framing, water, sewer, gas and electrical connections, then the interior work that makes the space feel like a home rather than a converted room.
What the work includes
Handled properly, in the right order.
Structure
Foundation, framing, roof and envelope built to the same standard as a main-house build.
Utilities
Water, sewer, gas and electrical service routed and connected, including panel work when required.
Compact interiors
Kitchen and bath layouts, storage and lighting planned for small square footage.

Our process
From vision to completion.
The same four stages on every project, so you always know where things stand.
- 01
Consultation
We walk the space, listen to how you use it and define scope, priorities and realistic budget ranges before anything is promised.
- 02
Planning
Selections, sequencing, materials and schedule are documented so expectations are aligned before the first day of work.
- 03
Construction
Clean, protected job sites and coordinated trades. Progress is communicated and quality is checked as the work advances.
- 04
Final Walkthrough
We review the finished work together, address every detail on the list and hand over a project that is genuinely complete.
Questions
Straight answers.
Can I build an ADU on my Livermore property?
Most single-family lots can accommodate one, but lot size, setbacks and utility capacity decide the specifics. We review your property and tell you what is realistic before you spend on design.
Is a garage conversion cheaper than a detached ADU?
Usually, because the structure and slab already exist. The trade-offs are ceiling height, insulation, natural light and losing the garage.
How long does an ADU take?
Permitting and construction are separate timelines, and permitting varies by jurisdiction. We give you both estimates and keep you updated as the application moves.
Do ADUs need separate utilities?
Sometimes. Requirements differ by jurisdiction and by whether the unit is detached. We confirm what your project needs during the feasibility review.
