What Chino Hills Homeowners Say About Ellery ADU Studio Chino Hills
We’ve been designing, permitting, and building ADUs in Chino Hills since 2015, and the feedback we value most comes from homeowners who’ve lived through the process start to finish. Nadia Ellery and our team don’t chase stars; we chase outcomes - permits issued, slabs poured, keys handed over, and a photo record that proves what got done. The reviews below come from real Chino Hills projects, and they reflect what happens when one contract covers design, build, and the paperwork in between.
Recent Reviews
“We started with a garage conversion idea for our place near English Springs Road and didn’t know if the slab would even pass. Ellery’s crew measured it, told us the existing 4-inch slab was within range, and wrote the foundation line item into the quote that same day. No surprises, and the permit cleared Chino Hills Planning on the first submittal.”
Dale M., English Springs area, Chino Hills
“I had a written estimate from another builder for a detached ADU in Oak Tree Downs, but something felt off about the utility connection pricing. Ellery ran the free second opinion, spotted that the sewer lateral wasn’t accounted for, and still came in with a tighter number that didn’t change once we signed. The Haven Standard Clause 1 thing - written price before work starts - they actually mean it.”
Beatriz M., Oak Tree Downs, Chino Hills
“Our junior ADU in Rolling Ridge came with a nightmare neighbor situation over setbacks. Nadia walked the property herself, flagged the variance we’d need from the city, and explained it in plain terms: extra distance between the unit and the property line, and here’s how that affects your footprint. She was right about the timeline too. Permit took eight weeks, not the four the counter clerk guessed on my first visit.”
Lisa M., Rolling Ridge, Chino Hills
“We went with a modular system from Abodu for a detached unit in Butterfield Ranch, and I assumed we’d need a separate coordinator for the factory delivery. Ellery handled the spec, the crane day, and the Chino Hills inspection scheduling under the same contract. One phone number, one photo record after every visit, and the 365-Day Done Right Promise in writing before anyone broke ground.”
Hector D., Butterfield Ranch, Chino Hills
“The garage conversion on our Sleepy Hollow property had a rotted header above the door that nobody else mentioned during walkthroughs. Ellery’s crew documented it with photos on the first visit, wrote it into the scope as a line item, and didn’t treat it like a discovery charge later. That’s the difference between a summary of how it felt and evidence of what was found.”
Dale M., Sleepy Hollow, Chino Hills
“I called three places about a detached ADU near Vellano Country Club. Two said ‘call for a quote’ and one sent a ballpark over text. Ellery sent a written scope with every line item - design, permitting, site prep, utilities, final inspection - and the price didn’t budge. When Chino Hills Fire Department asked for an extra egress window, they absorbed it under Clause 5. No door-side upsell, just a note in the photo record showing the new location.”

Why Customers Trust Us
The pattern in these reviews isn’t accidental. Every Chino Hills project we take on runs through the same five checkpoints: a written price before any work starts (Haven Standard, Clause 1), a documented photo record on every visit, permits pulled and inspections passed, a single contract covering design through final walkthrough, and the 365-Day Done Right Promise backed in writing. When Dale mentions the slab assessment, Beatriz notes the second opinion, or Lisa describes the setback variance, they’re describing the same system at work - one that doesn’t let the designer and builder point fingers at each other because they’re the same team under one roof.
