What Simi Valley Homeowners Say About Ellery ADU Studio Simi Valley
We’ve been designing and building ADUs in Simi Valley since 2015, and we’ve learned that the best review isn’t the one we ask for, it’s the one a homeowner volunteers after their final inspection passes. Every project starts with a written price under Haven Standard Clause 1 and ends with a documented photo record, so there’s never a gap between what was promised and what was delivered. The feedback below comes from actual projects across Simi Valley, from Wood Ranch to Santa Susana Knolls.
Recent Reviews
“We got three quotes for our garage conversion on Royal Avenue. Ellery was the only one who gave us a written price upfront, not a ‘call us back’ number. The slab was only 3.5 inches, and Nadia flagged it during the site walk instead of burying it as a change order later. Final permit passed in April, tenant moved in May.”
Justin Y., Wood Ranch, Simi Valley
“Our Junior ADU off Yosemite Avenue had a setback variance issue, the city wanted 4 feet more clearance than we had. Nadia’s team redrew the site plan instead of telling us to shrink the unit. We got our 420 square feet, permit approved on first submittal, and the photo record showed every framing inspection. Haven Clause 5 meant zero surprises.”
Andres C., Santa Susana Knolls, Simi Valley
“We were leaning toward a prefab unit from Abodu but didn’t want to manage the site prep and utility tie-ins ourselves. Ellery handled the whole thing under one contract, foundation through final inspection. The written price was $187,000 all-in, and that’s what we paid. No ‘oops, the trenching was deeper than expected’ nonsense.”
Kelly D., Indian Hills, Simi Valley
“Nadia gave us a free second opinion on a quote we’d already gotten for our detached ADU on Blackstock Avenue. The other contractor hadn’t included fire sprinkler costs, which Simi Valley requires for anything over 1,200 square feet. She found $14,000 in missing line items. We hired her instead, permit set was complete in six weeks.”
Rosa G., Bridle Path, Simi Valley
“The 365-Day Done Right Promise actually mattered. Our final walkthrough showed a window that didn’t match the approved egress plan, a sub trade had swapped it without telling anyone. Nadia’s crew ripped it out and re-framed it, no argument, no invoice. The photo record from the original rough inspection proved what was supposed to be there.”
Justin Y., Wood Ranch, Simi Valley
“We started with a garage conversion, then decided mid-design to go detached instead. Most studios would have charged us for two full design cycles. Nadia applied what we’d already paid toward the new scope, wrote a fresh price, and we kept moving. That’s not how most Simi Valley contractors operate.”
