Why San Jose Homeowners Choose Fielding ADU San Jose for ADU
Twenty years of building discipline, a written price before any work starts, and a one-year workmanship guarantee in plain English. That’s the short version. San Jose homeowners keep calling Fielding ADU San Jose because we do what the industry too often doesn’t: show up inside the window we gave you, build it square and permitted, and leave the site clean when we’re done. Reed Calloway leads our San Jose team, and every job is covered by The Garrison Standard. No surprises at the door. No prices that drift once hammer meets nail.
6 Reasons We’re San Jose’s Top ADU Company
Experience That Shows Up on Schedule
Fielding ADU Builders has been doing additions and ADUs since 2006, and our San Jose branch carries that same discipline into every job. We’ve framed enough ADUs in this market to know what Santa Clara County inspectors look for, how San Jose’s setback rules shape a detached unit, and where South Bay soil conditions affect foundation planning. That experience means fewer surprises and a smoother permit path. Reed Calloway and the local team have guided homeowners through detached ADUs, garage conversions, and second-story additions across the city.
A Local Reputation Built on Showing Up
San Jose homeowners are tired of contractors who ghost estimates and vanish mid-project. The feedback we hear most often from Bay Area clients is simple: Fielding does what the quote says it will do. Our reputation in San Jose comes from completed jobs, passed inspections, and neighbors who recommend us to neighbors. We don’t chase volume. We protect the referral pipeline that keeps our calendar full in Alum Rock, Burbank, and Willow Glen.
Licensed, Insured, and Held to A High Standard
Every pro working under the Fielding ADU San Jose name is required to hold the license and insurance their state requires. We don’t cut corners on credentials, and we don’t ask you to take our word for it. The Garrison Standard applies to every job we take, which means the work is done by the book, permitted, and inspected before we call it done. You should expect that from any ADU contractor in San Jose. We make sure it’s true for us.
Brand Expertise: Abodu, Cover, Dvele, and More
Prefab and panelized ADUs have changed how San Jose homeowners think about adding square footage. We work regularly with Abodu, Cover, and Dvele systems, and that experience matters. Factory-built components arrive on a truck, but site prep, foundation work, utility connections, and finish details still demand local skill. We know how these systems go together, where they interact with San Jose’s permit process, and how to keep the schedule on track when a prefab delivery hits a snag. If you’re weighing prefab against stick-built, we can walk you through both honestly.
Transparent Pricing in Writing Before Work Starts
Every Fielding ADU San Jose job gets a written line-item price before any work begins. Not an estimate scribbled on a napkin. Not a verbal ballpark that shifts once demo starts. The price we put in writing is the price you pay, and change orders only happen if you ask for a change. That’s The Garrison Code: price in writing before any work starts. For ADU construction in San Jose, where costs can swing wildly from one contractor to the next, that kind of clarity is rare and valuable.
A One-Year Warranty We Put in Writing
We stand behind our work for a full year, in writing. If something fails within twelve months of completion, we come back and make it right at no charge. That covers the construction work we do, the details we touch, and the standards we set. No fine print that carves out everything that matters. Just a straightforward promise from a San Jose ADU builder who expects the work to hold up.
Our Promise to You
Every Garrison company, including Fielding ADU San Jose, works to the same standard. We arrive inside the window we gave you. We put the price in writing before any work starts. We do the job by the book, the first time. We leave the site clean and squared away. And we guarantee the work in writing for a full year. If it fails in that time, we come back and make it right at no charge. That’s The Garrison Standard, and it isn’t optional for the crews who carry our name in San Jose. Reed Calloway and our local team are accountable to it on every single project.
