What North Hollywood Homeowners Say About Ellery ADU Studio North Hollywood
We’ve been designing and building ADUs in North Hollywood since 2015, and the feedback we value most comes from the homeowners who’ve lived through the process with us. Every review reflects the same three commitments: a written price before work starts, a documented photo record on every visit, and our 365-Day Done Right Promise backed in writing. These aren’t marketing slogans - they’re Haven Standard clauses, and they’re how we’ve earned trust across the Valley Village, Studio City, and Toluca Lake neighborhoods that border our North Hollywood base.
Recent Reviews
“We got three estimates for our garage conversion on Ben Avenue. Two came in verbal, one guy texted a number. Nadia’s team was the only one who put every line item in writing - foundation reinforcement, electrical subpanel, even the LADBS permit fees - before we signed. When the inspector flagged a venting detail, they fixed it same week and sent photos. No extra charge.”
Javier S.
Valley Village, North Hollywood area
“Our detached ADU on Tujunga Avenue hit a snag with the DWP service upgrade. I’d heard horror stories about contractors disappearing for months. Nadia’s crew kept showing up, kept photographing everything, and kept us in the loop. The written price stayed the written price. We moved our tenant in last March, and the unit’s been cash-flow positive since.”

“I brought Ellery a quote I’d already gotten for a Junior ADU conversion - my mom was moving in, and I wanted to be sure I wasn’t getting taken. Their Free Second Opinion saved us about $8,000. They caught that the other contractor had spec’d a full sewer lateral replacement when a spot repair was sufficient. Haven Standard Clause 1 means something here.”
Grace C.
Studio City, near the North Hollywood border
“The prefab route scared me. I didn’t want to coordinate between a factory in Sacramento, a local crane operator, and some permit expeditor I’d never met. Ellery handled the Abodu unit, the foundation, and the LADBS sign-off under one contract. One written price. When the module showed up 2 inches off on one corner, they adjusted the foundation, not the blame.”
Roger B.
Toluca Lake, North Hollywood adjacent
“We’d already fired one contractor who kept ‘finding’ problems that cost extra. Nadia’s team found real issues - our existing slab was only 3.5 inches, not the 4 needed for conversion - but they photographed it, explained the foundation line item in the original quote covered the remediation, and got it engineered. No surprise. No upsell. Just the work we’d agreed to.”
Javier S.
Valley Village, North Hollywood area
“The 365-Day Done Right Promise sounded like standard warranty language until we needed it. Our ADU’s mini-split started short-cycling in month eight. Ellery sent their HVAC sub, diagnosed a refrigerant leak in the line set, and handled the repair. No argument about whose scope it was. One contract means one throat to choke, and they know it.”

Why Customers Trust Us
These reviews land on the same points because the points are built into how we operate. Haven Standard Clause 1 locks your written price before any work starts - no “call for a quote,” no ballpark that balloons. Clause 5 locks the scope at signing; no door-side upsells when crews are already in your backyard. Every visit generates a documented photo record, so you see what was found and what was done, not a summary of how it felt.
Our one-contract design-build model means the designer and builder are the same entity. When Javier’s venting detail needed fixing, there was no finger-pointing between architect and contractor. When Paul’s DWP delay stretched the timeline, we absorbed the coordination, not the homeowner. And when Roger’s prefab module needed field adjustment, we adjusted it - because specifying Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or James Hardie systems is our job, not yours.
