What San Diego Homeowners Say About Fielding ADU San Diego
Reviews matter because an ADU is a six-figure decision on a property you already own. You want to know the crew shows up, the price holds, and the work gets done right. We earn every review the same way: written pricing before the first nail, background-checked crews in uniform, and The Garrison Standard behind the whole build. If something fails inside a year, we come back and fix it at no charge. That is the deal, in writing, every time.
Recent Reviews

“We converted our detached two-car garage in North Park into a 480-square-foot studio ADU. Reed walked the lot, pointed out where the sewer line would need to connect, and handed us a written price before we signed anything. The final invoice matched the first number to the penny. The unit rented within three weeks of completion.”
Amit R. – North Park, San Diego
“Our lot in Clairemont has a weird slope and I assumed a prefab unit would never work. Fielding brought a Mighty Buildings rep to the site visit and we worked through the foundation requirements together. They pulled the permits, handled the grading, and the unit was set in place eighteen weeks after we started. Clean job site every single day.”
Kevin M. – Clairemont, San Diego
“I hired Fielding to build a 750-square-foot addition for my mother in Chula Vista. The crew wore uniforms, introduced themselves on day one, and I never once wondered who was walking through my gate. Reed’s written guarantee spelled out exactly what the one-year coverage included. Nine months in, a minor cabinet hinge issue and they had someone out the same week.”
Luis F. – Chula Vista
“We looked at four ADU contractors in San Diego before Fielding. Two of them gave verbal estimates and one never sent anything at all. Reed gave us a line-item price on paper at the first meeting and explained which permit fees we’d pay the city directly. The garage conversion in Normal Heights came out exactly as drawn. No change orders, no surprises.”
Gabriela F. – Normal Heights, San Diego
“Fielding handled our Abodu unit in Mira Mesa from foundation to final inspection. They knew the platform inside and out, which mattered because the city had questions about setback requirements. Reed got the variance approved and kept us updated at every step. The unit passed final inspection on the first visit.”
Amit R. – Mira Mesa, San Diego
“After a previous contractor walked off our room addition in La Mesa halfway through framing, we were skeptical about hiring anyone again. Fielding came in, assessed what was salvageable, and gave us a written price to finish the job correctly. They even documented what the prior crew had done wrong so we had a record for insurance. The addition is done, permitted, and we finally have the space we paid for.”
Gabriela F. – La Mesa
Why Customers Trust Us
The recurring theme in these reviews is not charm. It is paperwork. Written pricing before work starts. A written one-year guarantee that names what it covers and how we fix it. Permits pulled and inspections passed. The Garrison Code is how we operate on every job, from a 300-square-foot garage conversion to a full two-bedroom addition: show up in the window, price in writing, by the book, leave it clean, and stand behind it for a year. Reed Calloway runs Fielding ADU San Diego personally, and he answers the phone live, 24 hours a day. Every crew member is background-checked and arrives in uniform. We build with prefab platforms like Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, and we also build conventional with James Hardie siding and Tuff Shed-style structures. If you are pricing an ADU, garage conversion, or room addition in San Diego, call (858) 264-3027 for a free estimate. You’ll get a real person and a real number.
