What Pomona Homeowners Say About Ellery ADU Studio Pomona
Reviews in the ADU world carry extra weight because the project takes months, not hours. A homeowner can’t evaluate the finished work until permits close and the certificate of occupancy is in hand. The testimonials below come from Pomona property owners who’ve made it through that full cycle with us - design, permitting, construction, and final inspection. We’re proud that most of our new calls come from referrals or from neighbors who walked through a completed Ellery ADU and asked who built it.
Recent Reviews
“We’d gotten a $14,500 quote for drawings from another firm, but no permit timeline and no construction price. Nadia Ellery came back with a single written number for our Mayfair Park garage conversion, from the first site visit through final inspection. The photo record from every visit meant I could show my sister in Sacramento exactly where we stood without driving down. We closed permits in November, right on the schedule she’d written in April.”
- Darnell I., Mayfair Park, Pomona
“Our lot in Phillips Ranch drops about four feet from front to back, and two other designers told us a detached ADU would need a retaining wall that would eat half the budget. Nadia walked the grade with a laser level and found we could split the difference with a stepped foundation - saved us eleven thousand dollars on the site prep line item. The Haven Standard photo record showed the rebar layout before the pour, which mattered because Pomona Building & Safety wanted to see the tie-ins with their own eyes.”
- Sarah H., Phillips Ranch, Pomona
“I’m a retired architect, so I came in thinking I’d handle the design and just hire Ellery for permitting and build. Nadia convinced me to let her team produce the permit set under the same contract - she pointed out that Pomona’s fire separation requirements for garage conversions had changed in 2023, and my old code knowledge would have cost us a resubmission. The drawings sailed through plan check in three weeks. Under Clause 5, the scope never budged from the written price she gave us in January.”
- Karen W., Lincoln Park, Pomona
“We were set on a prefab unit from Abodu until Nadia ran the utility distances from our main house in Westmont. The sewer lateral was 78 feet, and the electrical trench would have needed to cross a mature oak root zone that the city arborist flagged. She priced both the Abodu route and a stick-built Junior ADU attached to the existing structure - the JADU came in lower, with no variances, and we didn’t lose the tree. The 365-Day Done Right Promise was in writing before we signed, which my wife made me read aloud.”
- Javier H., Westmont, Pomona
“My mother needed to move in, and we were looking at assisted living costs of six thousand a month. Nadia priced a full garage conversion ADU in our Mayfair Park neighborhood at less than two years of that - and the written price included the Pomona utility connection fees, which another contractor had left as a TBD that would have added four thousand after the fact. The photo record from the insulation inspection caught a gap in the fire-rated assembly that the crew fixed same-day, before the drywall went up. I wouldn’t have known to look.”
- Darnell I., Mayfair Park, Pomona
“We’d already paid a deposit to a designer in Claremont when a neighbor told us about Ellery’s Free Second Opinion. Nadia reviewed the estimate and found that the foundation line item assumed a 6-inch slab - our 1954 garage in Lincoln Park has a 3-inch slab with no rebar, which meant a full replacement, not a retrofit. The original quote would have ballooned by eight thousand dollars minimum. We forfeited the Claremont deposit and came back to Ellery for the full design-build contract. The written price she gave us matched the final invoice to the dollar.”

Why Customers Trust Us
These reviews share a pattern that isn’t accidental. Every Pomona homeowner above mentions the same three things: a written price that held up, documentation they could verify with their own eyes, and a project that closed without the designer and builder pointing at each other.
That’s the Haven Standard in practice. Clause 1 gives you the full project price before any work starts - not an estimate, not a range, a written number. The documented photo record on every visit means you receive evidence of what was found and what was done, not a summary of how it felt. And the 365-Day Done Right Promise, backed in writing before your project begins, means if the finished ADU doesn’t match the permitted drawings, we make it right.
We’ve designed, permitted, and built over 900 ADUs since 2015. Every one started with a written price and ended with a photo record. No voicemail queues, no callback promises that evaporate - a live person answers calls 24/7 at (657) 286-7915.
Already have a written estimate in hand? Ask us for a Free Second Opinion. We’ll tell you what’s solid, what’s missing, and what Pomona-specific conditions the other scope may have overlooked.
