How Fielding ADU San Jose Was Born in San Jose
We brought Fielding ADU to San Jose because this city needed a different kind of ADU builder. Not a company that treats accessory dwelling units as a side job, but a team that builds them square, permitted, and finished on schedule, every single time. The parent company behind us, Garrison Partners, has been doing exactly that since 2006, and when the time came to open a San Jose branch, Reed Calloway was asked to lead it.
Reed grew up in the trades and spent years watching homeowners get worn down by the same three problems: no-shows, prices that moved at the door, and work that looked fine until the first rain. When he started assembling the San Jose team, he made one rule clear: we don’t operate that way. We show up inside the window we gave, we put the price in writing before any work starts, and we stand behind the finished job for a full year. That’s not a pitch. It’s The Garrison Code, and every location that carries the Fielding name is required to work by it. Reed opened this branch because he knew San Jose homeowners were tired of the alternative.
Reed Calloway’s Personal Connection to the ADU Trade
Reed Calloway didn’t stumble into ADU work. He was raised around framing crews and finish carpenters, the kind of people who wipe their boots before walking through a customer’s door and measure twice because measuring once costs someone money. From the time he was old enough to hold a speed square, he understood that building was a discipline, not just a job. That ethos followed him into his career, and it’s the reason ADUs specifically held his attention. An accessory dwelling unit is a small building, but it carries big weight: a place for aging parents, a rental that offsets a mortgage, a home office that finally gets someone out of the garage. Getting the foundation square, the framing true, and the permit closed matters in ways a homeowner feels for decades.
What kept him in the trade was the satisfaction of fixing what other builders got wrong. Early in his career, Reed was sent to a job in the South Bay where another company had framed an addition out of square by a visible margin. The homeowner had paid, the crew had left, and the problem sat there like a crooked grin. Reed spent a week correcting it. The smell of fresh lumber in that room, the feel of a chalk line snapping straight, the look on the homeowner’s face when he realized the walls finally met at right angles, those things stuck with him. That’s the work he wants to do in San Jose. If he weren’t doing this, he’d likely be teaching framing to young tradespeople. But as long as homeowners need ADUs built right, he’ll be here.
Meet Reed Calloway – The Person Behind Every Job
Reed Calloway is the Owner & Founder of Fielding ADU San Jose. He grew up around the construction trades and has spent more than a decade in residential building, with a focus on accessory dwelling units and additions. His training comes from years on active job sites, working alongside experienced tradespeople who taught him the difference between work that passes inspection and work that lasts. He knows San Jose’s building codes, its permit process, and the soil and weather conditions that affect how a foundation should be poured here.
What sets him apart from a corporate franchise technician is simple: he leads the local team, he walks the job sites, and he cares about how the work looks when the dumpster is gone. On weekends, Reed can be found restoring old woodworking tools, a hobby that keeps his eye sharp for detail. He approaches every ADU the same way he approaches that work: take the time, do it right, and don’t leave until it’s squared away. If you hire Fielding ADU San Jose, you get a builder who treats your property like it matters, because to him, it does.
Our Promise to San Jose Homeowners
Every job we take follows The Garrison Code. That means we arrive inside the window we gave you, not two days later. We put the price in writing before any work starts, so the number you agree to is the number you pay. We do the job by the book, the first time, pulling the permits and scheduling the inspections that San Jose requires. We leave the site clean and squared away at the end of every day. And we stand behind the work for a full year in writing. If something fails in that time, we come back and make it right at no charge.
These aren’t slogans. They’re the rules we work by, and they exist because homeowners in San Jose have dealt with the opposite for too long. Reed built this branch around those rules because he’s seen what happens when companies don’t have them.
Our Credentials
Fielding ADU San Jose operates as a local branch of Fielding ADU Builders, part of the Garrison Partners family. Here’s what that means for you:
- Licensed: Every pro working under our name is required to hold the license their state requires for the work they perform. We don’t cut corners on credentials.
- Insured & Bonded: The same rule applies to insurance and bonding. Homeowners should never have to worry about liability when a crew is on their property.
- Local experience: Reed Calloway has spent more than a decade in residential construction, much of it in the South Bay. He knows San Jose’s permit office, its inspection rhythms, and its neighborhoods.
- Strong local reputation: Homeowners across San Jose and the surrounding cities have come to trust the Fielding name because the work holds up and the process is predictable.
Why do these credentials matter to a homeowner? Because a licensed, insured, bonded builder with local experience is one you can hold accountable. If something goes wrong, there’s a real company with a real address and a real reputation on the line. That matters when someone is working in your home and on your property.
Rooted in San Jose
Our service area includes San Jose, Sunnyvale, Campbell, Menlo Park, Saratoga, Newark, Scotts Valley, Stanford, Boulder Creek, Alum Rock, Burbank, and Santa Clara. We build ADUs in older neighborhoods with tight lots, in newer subdivisions with strict HOA rules, and everywhere in between. Reed knows the difference between permitting an ADU in Alum Rock versus Menlo Park, and he plans every job around the specific requirements of the city where it’s being built. That’s the value of a local team: we don’t have to look up your city’s codes. We already work with them every day.
