What Garden Grove Homeowners Say About Ellery ADU Studio Garden Grove
We’ve been designing, permitting, and building ADUs in Garden Grove since 2015. Reviews don’t come from asking nicely at the end of a job. They come from doing what we said we’d do, at the price we wrote down, and leaving a photo record that proves it. Here’s what that looks like from the homeowner’s side.
Recent Reviews
“We’d already paid another firm for garage conversion drawings when we found out they never checked the setback. Nadia walked the site, measured to the property line herself, and spotted the variance issue in twenty minutes. She redid the whole permit set, got us through plan check in Garden Grove on the first submittal, and the final invoice matched her written quote exactly. Haven Clause 1 isn’t marketing. It’s how she actually runs the job.”

“Our Junior ADU in the Brookhurst corridor started as a conversation about my mother-in-law moving in. Nadia didn’t sell us a bigger project. She showed us the 500-square-foot max for a JADU under state law, explained how Garden Grove interprets the owner-occupancy rule, and we signed a scope that didn’t creep. The photo record from every inspection visit is on a shared drive. My wife and I both work, so we never had to be home wondering what happened that day.”

“I had a written estimate from a prefab company for a backyard unit and something felt off. Ellery’s Free Second Opinion saved me about fourteen thousand dollars. Nadia pointed out that their ‘turnkey’ price didn’t include the Garden Grove sewer lateral upgrade or the electrical service bump. She specified a Dvele unit instead, coordinated the same single contract for design, site prep, and utility tie-in, and we still came in under what the other quote pretended was the total.”

“The slab in our 1972 garage was four inches, which Nadia said was within range for a conversion foundation, but the soil report came back with liquefaction potential she hadn’t expected. She didn’t eat the cost and hide it. She called, explained the over-excavation and engineered fill line item, and we amended the written scope with a fixed price for that condition. The 365-Day Done Right Promise was already in the contract. We didn’t need it, but knowing it was there, in writing, is why I recommend Ellery to my neighbors.”

“We interviewed three design-build firms for a detached ADU behind our house on the east side of Garden Grove. Nadia was the only one who brought up the Oak View Sanitary District sewer capacity fee before we signed. The others would have hit us with it during construction. Her permit set included the landscape plan Garden Grove requires for any new detached unit over 640 square feet. Plan check had one correction, we handled it in two days, and the certificate of occupancy came through in March. Written price before work started. Documented photo record on every visit. That’s not a slogan. That’s what happened.”

“I’m a general contractor myself, but I don’t do ADUs. I hired Nadia for the design and permitting on a garage conversion in the West Grove, then had her crew handle the build too because their license number was on every page and I could verify it. The one-contract model matters. I’ve seen jobs where the designer blames the builder and the builder blames the designer and the homeowner pays for both mistakes. Nadia’s team drew it, built it, and if something was off, there was only one place to point. The photo record from each inspection was in my inbox before I asked. That’s professional.”

Why Customers Trust Us
These aren’t cherry-picked stories. They’re what happens when you operate under the same rules on every job.
The Haven Standard governs everything we do. Clause 1 means a written price before any work starts, not an estimate that drifts. Clause 5 locks the scope at signing, so there’s no door-side upsell when you’re already committed. The documented photo record on every visit means you see what we found and what we did, not a summary of how it felt. And the 365-Day Done Right Promise, backed in writing before your project starts, means if the finished ADU doesn’t match the permitted drawings, we make it right.
We’ve designed, permitted, and built more than 900 ADUs since 2015. Every one of them started with a written price. Every one of them ended with a photo record. We’re independently owned and operated here in Garden Grove, and Nadia Ellery’s license number appears on every page of this site, verified, not just claimed.
If you’re pricing an ADU project, or if you have a written estimate that doesn’t sit right, call (657) 567-6590. A live person answers, and we’ll schedule your free estimate or second opinion at a time that works.
