Why Homeowners Choose Ellery ADU Studio for ADU
Ellery ADU Studio has designed, permitted, and built more than 900 accessory dwelling units since 2015. That’s more than a decade of working with Los Angeles zoning codes, neighborhood review boards, and soils that shift more than anyone expects. Homeowners choose us because every project starts with a written price, a written scope, and a written warranty – before anyone picks up a hammer. It’s the Haven Standard, and it’s built into every contract we sign.
6 Reasons We’re a Top ADU Company
1. More Than a Decade of ADU-Specific Experience
We’ve been building ADUs since 2015, the exact year California overhauled its ADU laws and opened the floodgates. From that first wave of permits to today’s Los Angeles accessory dwelling unit market, we’ve seen every code interpretation, every setback dispute, and every foundation surprise the city can throw at a project. That experience means we catch issues during design, not during construction, when they cost real money.
2. A Reputation Built on Documentation, Not Promises
Homeowners who compare Ellery ADU Studio against other ADU companies tend to say the same thing: our paperwork is different. Every job leaves with a documented record – photos, measurements, permit notes, and a final walkthrough checklist. Our strong local reputation comes from the fact that when a homeowner asks what happened on their project, we can show them, not just tell them.
3. State-Licensed and Properly Insured Across Every Project
Every pro working under the Ellery ADU Studio name is required to hold the license and insurance the state of California requires for the work they perform. We verify credentials before anyone steps onto your property. You’ll see the license number on your estimate, on your contract, and on the final documentation packet.
4. Real Expertise with Abodu, Cover, and Dvele Panel Systems
Prefab ADU manufacturers like Abodu and Cover have changed what’s possible for Los Angeles homeowners, but the panels only work if the site work and foundation are done right. Our team has installed Dvele and Abodu systems and knows how to prep Los Angeles lots for panel delivery, crane access, and utility hookups. We’ll walk you through which system makes sense for your lot, your budget, and your timeline – and we’ll put that recommendation in writing.
5. Transparent Pricing You Can Read Before You Commit
Every Ellery ADU Studio project is quoted in writing before it starts. That quote includes the flat price, the written scope, and the written warranty – Clause 1 of the Haven Standard. No door-to-door upsell, no “while we’re in here” additions, no change orders because someone forgot to count the windows. If a change is truly necessary, you get a written change order with a new price before we proceed.
6. A Warranty Backed by Written Terms
Our workmanship warranty is spelled out in your contract, not hidden in a verbal handshake. The Haven Standard requires every job to leave with a documented record, so if something needs attention down the line, we can look back at exactly what was installed, when, and how. You’ll know what’s covered, for how long, and what to do if you need service.
Our Promise to You
Every ADU we build is quoted in writing before we start – flat price, written scope, written warranty. That’s Clause 1 of the Haven Standard, and it’s the reason homeowners feel confident choosing Ellery ADU Studio. Here’s what else you can expect on every project, in every city we serve:
- Have it in writing. Your price, your scope, and your warranty are documented before we begin. No exceptions.
- Arrive on schedule. You get a real window, a named point of contact, and a text when our team is on the way.
- Verified crews. Every pro is licensed, insured, and background-checked. Their license number appears on the page.
- Evidence on every job. Photos and readings of what we found – not a story about what we thought we saw.
- No surprises. No upsell at the door, no scope creep, no “while we are in here” charges. If it’s not in the written scope, it doesn’t get added without a signed change order.
If you’re not satisfied with our work, we don’t disappear. You call, we return, and we make it right according to the terms of your written warranty. That’s the standard every Ellery ADU Studio location is held to.
