ADU Specials in San Jose, CA
Fielding ADU San Jose runs offers the same way we run job sites: straightforward, with the numbers laid out before anyone picks up a hammer. Call (669) 201-3984 and we’ll tell you exactly what the offer covers, who qualifies, and whether it makes sense for your lot. No bait, no fine-print gymnastics. Reed Calloway and the team would rather you know the real price of an ADU, garage conversion, or room addition before you commit to a single thing. And every offer below comes with the same standing policy we’ve kept since Garrison Partners started in 2006: written price before work starts, written guarantee for a full year after.
Current Offers

Free Written Estimate on Any ADU, Garage Conversion, or Room Addition
We put the full project price in writing before any work begins, and this offer makes that estimate completely free. You’ll get a line-item breakdown of labor, materials, permits, and the build method we recommend, whether that’s a conventional stick build with James Hardie siding or a prefab platform like Abodu, Cover, or Boxabl. Homeowners in Willow Glen, Almaden Valley, and Evergreen qualify.
Valid through March 31, 2027. Mention this offer when you call (669) 201-3984.
Garage Conversion Planning Session at No Charge
If you’re comparing a garage conversion against a detached ADU, we’ll walk your property and give you an honest read on which path costs less and returns more. That includes checking your setback situation, talking through San Jose’s ADU permit path, and pricing both options side by side so you can decide with real numbers in hand. This is the offer for homeowners who aren’t sure yet and don’t want to pay for advice.
Valid through March 31, 2027. Mention this offer when you call (669) 201-3984.
Senior and Military Courtesy: Priority Scheduling on Free Estimates
Homeowners 65 and older, and active-duty or retired military, get first pick of our estimate calendar at no extra charge. That means shorter wait times for the written price, not a discount gimmick that gets padded back into the bid. We’ve run this courtesy since we opened, and it’s the offer that fits how we operate: show up in the window, price in writing, by the book.
Valid through March 31, 2027. Mention this offer when you call (669) 201-3984.
First-Time Customer Offer: Second Opinion on an Existing Bid
Already have a bid from another San Jose contractor? Bring it to us before March 31, 2027, and we’ll review it line by line against what we’d charge, at no cost. If your existing bid is fair, we’ll tell you that. If it’s not, you’ll see exactly where the money is going. This offer pairs naturally with our written-price-first policy: the number you approve is the number on the final invoice.
Valid through March 31, 2027. Mention this offer when you call (669) 201-3984.
Prefab ADU Consultation: Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab
If you’ve been researching factory-built ADUs, this consult saves you the guesswork on site prep, foundation, and utility hookup costs that prefab brochures don’t cover. We’ve installed and finished all major platforms the market actually uses, including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, so we can price the full job, not just the box. This offer includes a written estimate for the complete build.
Valid through March 31, 2027. Mention this offer when you call (669) 201-3984.
What Every Fielding ADU San Jose Offer Carries
We don’t run discounts that quietly shrink the scope of work. Every offer on this page rides on the same three commitments we make on every single project in San Jose:
- Written price before work starts. You get the full number on paper before a single nail is driven. The figure you approve on day one is the figure on the final invoice, no change orders, no surprise line items.
- The 365-Day Done Right Promise. Every addition, ADU, and garage conversion is backed in writing for one full year. If something fails inside that window, we return at no charge and correct the defect. That’s the Garrison Standard, and it’s spelled out on paper, including how long it runs and exactly how we make it right.
- Background-checked, uniformed crew. Every person who sets foot on your property has been verified before they arrive. You’ll know who’s on site, what they’re doing, and why.
How to Redeem

First, call (669) 201-3984 and mention the offer by name. A live person answers, noon or midnight. Second, we’ll book the free estimate or consultation at a time that works for you, and we’ll confirm the offer applies to your project. Third, the offer is applied when you approve the written estimate, not after work starts. That’s the whole process.
Why We Run Offers This Way
The math on an ADU or garage conversion in San Jose is already big enough: permits, plans, foundation, utilities, finishes. Adding a fake discount on top of a padded bid doesn’t help anyone. We’d rather give you the real number, show you what the offer saves, and let the written guarantee carry the rest. Reed Calloway built Fielding ADU San Jose on that logic, and it’s the same logic behind every offer above.
What About Permits and Setbacks?
Every offer on this page presumes the work will be permitted. San Jose requires ADU permits, and garage conversions often need a setback variance, which is the city’s written permission to build closer to the property line than the standard rule allows. We pull permits, we pass inspections, and we don’t cut corners to make a coupon look better than it is. The price you approve includes the legal work, not just the construction.
Do the Offers Stack?
No. One offer per project, and we’ll tell you upfront which one saves you the most on your specific scope. That’s the honest version of a deal, and it’s the only kind we run.
Call (669) 201-3984 to claim any offer on this page. Mention it when you call, and we’ll take it from there. Estimates are free, the price goes in writing, and the guarantee lasts a full year after the work is done.
