What Huntington Beach Homeowners Say About Ellery ADU Studio Huntington Beach
We’ve completed more than 900 ADUs since 2015, and every one of them left a paper trail: a written price before we started, a photo record of what we found and what we fixed, and a final walkthrough where the owner signed off. Reviews don’t come from asking nicely at the end. They come from not surprising people in the middle. Here’s what Huntington Beach homeowners actually said after living with our work.
Recent Reviews
“We’d already been quoted $18,000 for drawings by a separate architect who couldn’t tell us what the build would actually cost. Nadia walked our garage in Huntington Beach, measured the slab at 4 inches, noted the electrical panel had 30 amps of headroom, and gave us a written $147,000 all-in number for the garage conversion ADU - drawings through final inspection. We signed one contract. The price at closeout matched the price at signing, and we have 340 photos showing every phase.”

“Our lot in the Huntington Harbour area has a 5-foot side setback, which I thought killed the detached ADU. Nadia found a Huntington Beach variance path for accessory structures under 16 feet that we’d missed entirely. She specified a Cover unit, coordinated their factory delivery with our foundation pour, and the city signed off on the first submittal. The photo record showed the rebar grid before the pour, the anchor bolt placement, and the final utility connections. I’ve shown those photos to three neighbors who are now building.”
- Eric N., Huntington Beach
“I had a written estimate from another firm for a Junior ADU interior conversion - $89,000, but the scope was two pages of vague bullet points. Nadia gave us a Free Second Opinion. She found they hadn’t priced the separate meter, the fire-rated door assembly, or the kitchenette venting through our existing roof. Her written scope was 11 pages with line items. Final invoice was $94,000, but we knew that number on day one. No surprises, no change orders, and the 365-Day Done Right Promise is actually in our file, in writing.”
- Neil M., Huntington Beach
“We wanted a prefab ADU and got lost in the brand websites - Abodu versus Mighty Buildings versus Boxabl, all promising different timelines. Nadia broke down the real landed costs for our Huntington Beach lot: foundation, crane access over our fence line, utility trenching to the alley. She didn’t push one brand. She showed us three written scenarios, each with a documented photo record clause built in. We went with Plant Prefab, and her crew handled the site prep and utility tie-ins under the same contract. One phone number, one schedule, one person accountable.”
- Cole B., Huntington Beach
“The garage conversion ADU we built in the Oak View neighborhood had an existing slab with a crack running corner to corner. Nadia didn’t gloss over it. She brought in a soils report, priced the epoxy injection and the supplemental footing as a line item we could see, and photographed the repair before we covered it. That’s the kind of thing you don’t think about until you’re three years in and the tile pops. We have the photo. We have the warranty. We have the peace of mind.”
- Daniel H., Huntington Beach
“I called at 9 PM on a Tuesday because I was staring at three competing estimates and couldn’t tell which one was real. A live person answered - no voicemail, no callback tomorrow. Nadia scheduled the Free Second Opinion for Thursday morning. She found one estimate had left out the Huntington Beach school fees, another hadn’t priced the sewer lateral work our 1950s lot would need. Her written price wasn’t the lowest, but it was the only one that included everything. Six months later, our detached ADU is rented and the tenant’s rent covers two-thirds of our mortgage.”

Why Customers Trust Us

Every review above mentions the same three things, and they’re not accidents. They’re the Haven Standard, which governs every project we take in Huntington Beach.
Written price before work starts. Haven Clause 1 means you’ll never see “call for a quote” on our site or hear it on our phone. Nadia Ellery builds your scope item by item, attaches a dollar figure to each, and locks it at signing. The words “allowance” and “TBD” don’t appear in our contracts.
Documented photo record on every visit. Our crews photograph what they found, what they did, and what the space looked like before they left. You don’t get a summary of how it felt. You get evidence. That’s Haven Clause 3, and it’s how Daniel H. knew his slab crack was handled correctly before it was hidden forever.
365-Day Done Right Promise. If the finished ADU doesn’t match the permitted drawings, we make it right - in writing, before your project starts, not as a verbal assurance that evaporates when you need it. Haven Clause 5. Neil M. has that document in his file.
We’ve designed, permitted, and built over 900 ADUs since 2015. Every one started with a written price. Every one ended with a photo record. And when Huntington Beach homeowners like Cole B. or Eric N. refer their neighbors, it’s because the experience matched the promise.
Call (562) 263-3350 to schedule your free estimate. If you already have a written estimate in hand, ask for our Free Second Opinion - we’ll tell you what’s included, what’s missing, and what your real landed cost looks like in Huntington Beach.
