Fielding ADU Builders in California

Fielding ADU Builders in California

Fielding ADU Builders specialists are the accessory dwelling unit and room addition experts inside the Garrison Partners family. We plan, permit, and build backyard ADUs, garage conversions, and attached additions for homeowners across California who want more living space without moving. Every project carries The Garrison Standard: a written price before work starts, permits pulled by the book, background-checked uniformed crews on site, and a one-year written guarantee most contractors never put on paper. You get one team, one standard, and a project that finishes clean.

Why California Homeowners Choose Fielding ADU Builders

California homeowners have watched state laws change to make ADUs easier to permit, but the hard part was never the paperwork. It’s finding a builder who shows up when they say they will and holds the price. We hand you a written price before a single nail is driven, every time, with no exceptions. The number you approve on day one is the number on the final invoice. Our crews are background-checked and uniformed, so you know exactly who is on your property and why they’re there. We work with leading prefab and modular platforms including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, as well as conventional builds with James Hardie siding and Tuff Shed-style structures. That range lets us match the right build method to your lot, your budget, and your timeline instead of forcing one approach onto every project. When you call, a live person answers. No voicemail tree, no callback queue, whether it’s noon or midnight.

Backed by the Garrison Partners Family

Fielding ADU Builders is an independent local business that agreed to hold itself to The Garrison Standard. Garrison Partners, the parent organization behind us, has been building to that standard since 2006. The 365-Day Done Right Promise applies to every ADU and addition we build in California: the work is guaranteed in writing for a full year, and if it fails in that time, we return at no charge and correct the defect. A garrison is the unit stationed to protect a place and keep it ready around the clock. That’s the name, and it’s the promise: a team that shows up, holds the line, and leaves your home better than they found it.
