What Thousand Oaks Homeowners Say About Ellery ADU Studio Thousand Oaks
Reviews matter because an ADU is the biggest home investment most people make after the house itself. We’re not asking for trust based on a star graphic. We’re asking because every project in Thousand Oaks since 2015 has started with a written price, ended with a documented photo record, and carried a 365-Day Done Right Promise in writing. The homeowners below are real people in real neighborhoods who went through our design-build process and can tell you what actually happened.
Recent Reviews
“We’d already been quoted $18,000 for ADU drawings by an architect in Westlake Village who wouldn’t even guarantee the plans would pass Ventura County review. Nadia came to our place in North Ranch, measured the garage herself, and had a full permit set plus written construction price back to us in eleven days. The county approved on first submittal. That $18,000 quote didn’t include a single page of structural calcs.”

“Our contractor in Newbury Park told us we needed a complete slab replacement for the garage conversion. Nadia pulled out a laser level, checked the existing slab at four points, and showed us the documentation: 4 inches thick, post-tension cables intact, within tolerance for a JADU under Thousand Oaks code. Saved us $14,000 on a foundation line item we didn’t need. She put that in writing before we signed anything.”

“We were looking at a Cover unit for our backyard in Lang Ranch. Two other ‘ADU companies’ we talked to couldn’t tell us how Cover’s foundation specs intersect with Thousand Oaks grading requirements or whether the city would accept their pre-approved plans. Nadia had already permitted three Cover units in Ventura County. She specified the exact pier depth, coordinated the geotech report, and the foundation passed inspection on the first visit. One contract, one written price, no designer blaming the builder.”

“The Haven Standard photo record sounds like a nice touch until you actually need it. We had a question six months after move-in about whether the electrical subpanel was rated for the load we’d discussed. Nadia sent us the dated photo from rough electrical showing the panel model, the breaker layout, and her technician’s notation. Took four minutes to resolve. Try getting that from a contractor who ‘doesn’t keep old job photos.'”

“We got a written estimate from another firm for our detached ADU in Dos Vientos: $285,000, but the line items stopped at ‘finish work’ with no specification of flooring, fixtures, or appliance allowance. Nadia’s quote broke out every material grade, every labor hour category, and every permit fee to the dollar. Under Haven Clause 1, that written price was the price. We came in $3,400 under because we opted for a different window package. She credited us the difference. I’ve never had a contractor suggest I pay less than the quote.”

“Our junior ADU in the Lynn Ranch area needed a setback variance - the city wanted four extra feet between our conversion and the property line due to an easement we didn’t know existed. Nadia had flagged the easement in her initial site analysis, already priced the variance application into the written scope, and had the neighbor agreement drafted before we even knew there was an issue. Permit approved in seven weeks. I’ve heard horror stories about twelve-month variance delays in Thousand Oaks.”

Why Customers Trust Us
Every review above points to the same thing: specificity wins. A written price before work starts isn’t a marketing line - it’s Haven Standard Clause 1, and it means you’ll never hear “call for a quote” from our team. The documented photo record on every visit isn’t a feel-good extra; it’s evidence of what was found and what was done, delivered to your inbox before we leave the site. The 365-Day Done Right Promise isn’t a handshake - it’s in writing before your project starts, and it covers the finished ADU against the permitted drawings, period.
We’ve designed, permitted, and built 900+ ADUs since 2015. Every one started with a written price. Every one ended with a photo record.
