How Ellery ADU Studio Garden Grove Was Born in Garden Grove
It was a Tuesday morning in 2018, and we were standing in a driveway on Chapman Avenue, watching a homeowner cry. She had paid a contractor half upfront for a garage conversion. The crew had walked off three weeks ago. The framing was crooked, the electrical was roughed in without a permit, and the city had just red-tagged the whole project. She called us because someone at the Garden Grove permit counter mentioned our name. We spent two hours in her living room, sketching what it would actually take to salvage the work. The number she had been quoted was half what the job really cost. The contractor had known that. We didn’t take the job that day - it was too far gone - but we made a decision right there, in her kitchen with the avocado countertops and the smell of burnt coffee. Garden Grove needed an ADU company that wouldn’t do this. Wouldn’t disappear, wouldn’t guess at prices, wouldn’t treat the permit like an afterthought. Ellery ADU Studio had already built that reputation in other California markets. We opened this branch to bring it here.
Nadia Ellery’s Personal Connection to the ADU Trade
We got into this work sideways. Nadia Ellery started in architecture school, drawing floor plans at a drafting table that still sits in her garage, the kind with the parallel bar that clicks when you slide it. The smell of ammonia from blueprint machines, the weight of a metal scale ruler in your hand - these things imprinted early. But school taught design, not the permitting war. The real education came later, working alongside a tradesman who trained us in the field, someone who could read a foundation pour the way other people read faces. He’d stand in a trench at six in the morning, mud on his boots, and explain why a footing drain failed by pointing at the color of the soil. That sensory memory never leaves. The cold of rebar at dawn. The particular silence of a jobsite when something is about to go wrong.
The defining moment came in 2015, the year California changed its ADU law and the permitting queue became the actual product. Nadia was working on a detached unit in Orange County, and the project fell apart in the gap between the architect’s drawings and the builder’s interpretation. Six months of delay. The homeowner, a retired teacher, moved into a rental she couldn’t afford while we untangled it. That gap - between design and build, between promise and proof - is where ADU projects die. Nadia built Ellery ADU Studio to close it. The drawings, the permit set, and the build under one contract with one price. If she weren’t doing this, she’d probably be restoring old houses somewhere, working with her hands, solving problems that show their work. What gets her out of bed is the same thing that got her into it: a project where you can walk through at the end and point to exactly what was promised, exactly what was built, and the paper trail that connects them.
Meet Nadia Ellery - The Person Behind Every Job

Nadia Ellery, Owner & Founder, Ellery ADU Studio Garden Grove
Nadia leads every project from first measurement to final inspection. Her background spans architectural drafting, construction management, and the specific bureaucracy of California ADU permitting - the setbacks, the utility separations, the fire separation requirements that vary by jurisdiction. She holds the state licenses required for this work and has spent over a decade navigating the gap between what homeowners imagine and what cities will allow.
What separates Nadia from a corporate franchise technician is simple: she’s the one who answers when something goes sideways. She keeps a notebook of every jobsite problem she’s seen, organized by city, because Garden Grove’s planning department interprets the state code differently than Santa Ana’s, and knowing the difference saves months. On weekends, she restores mid-century furniture - the patience for sanding veneer translates directly to the patience for permit revision. Her commitment to you is direct: every price in writing before we start, every change documented, every inspection passed before we ask for final payment. That’s Clause 1 of the Haven Standard, and it’s non-negotiable.
Before
AfterOur Promise to Garden Grove Homeowners
We operate under the Haven Standard, a five-point code that governs every Ellery ADU Studio branch. Here’s what it means in Garden Grove:
Have it in writing. We learned this the hard way. Early in Nadia’s career, a homeowner in Westminster was quoted verbally for a foundation upgrade. The number changed by forty percent once excavation began. We don’t do that. Every Ellery ADU Studio job starts with a flat price, a written scope, and a written warranty. Clause 1.
Arrive on schedule. We give you a real window, a named technician, and a text when they’re on the way. Not because it’s fancy - because your time is the one thing we can’t replace.
Verified crews. Every professional working under our name is required to hold the license and insurance their state requires. We don’t send strangers to your home.
Evidence on every job. Photos and readings of what we actually found. When we leave, you have a record. When we return, we pick up where the documentation left off.
No surprises. No door upsell, no scope creep, no “while we’re in here.” The price we write is the price you pay.
Our Credentials

- State-licensed - Every ADU project in California requires a licensed contractor to pull permits and sign off on structural, electrical, and plumbing work. Working with an unlicensed operator voids your homeowner’s insurance if something fails. We don’t take that risk with your property.
- Insured & bonded - Our coverage protects your home, your finances, and the workers on your property. If a subcontractor damages your sewer line or a worker is injured on your stairs, the right policy is what stands between you and liability. We carry it because we’ve seen what happens when someone doesn’t.
- Years of local experience - Since opening this branch, we’ve worked in Garden Grove’s specific soil conditions, its planning department’s review timelines, and its neighborhood association covenants. That local knowledge prevents the delays that kill ADU budgets.
- Strong local reputation - We are known in this market for jobs that pass inspection the first time and for documentation that holds up when buyers ask questions years later.
These credentials matter because an ADU is a six-figure decision attached to your primary asset. The person you hire enters a year-long relationship with your property, your finances, and your family’s daily life. We don’t take that lightly.
Rooted in Garden Grove
This branch serves the neighborhoods we drive through daily: the postwar tracts near Brookhurst Street where original garages beg for conversion, the larger lots off Garden Grove Boulevard where detached units fit without eating the backyard, the pockets of Westminster and Fountain Valley where multigenerational families need separate space without separate mortgages. We know which blocks have alley access, which planning zones allow two-story ADUs, and where the soil conditions require engineered foundations. Nadia lives here. Her kids attend schools here. When we say we’re local, we mean we understand the specific pressure of housing costs in this corridor and the specific opportunity an ADU represents. Call us at (657) 567-6590 to schedule your free written estimate. We’re here Monday through Saturday, 7:30 AM to 7:30 PM, and Sunday, 7:30 AM to 7:30 PM.
