Why Santa Ana Homeowners Choose Ellery ADU Studio Santa Ana for ADU
Since 2015, Ellery ADU Studio has completed more than 900 ADUs across California with a single rule: every job gets a written price before anyone picks up a tool. In Santa Ana, Nadia Ellery leads a team that knows the difference between a standard lot in Floral Park and a hillside grade in Washington Square, because those details change your foundation, your setbacks, and your permit timeline. Our reviews come from homeowners who checked the three-star reviews first, asked hard questions, and still chose us.
6 Reasons We’re Santa Ana’s Top ADU Company
1. We Opened Here With Local Knowledge Already Built In
Ellery ADU Studio started in 2015, the same year California’s ADU law rewrote the rules and made the permit queue the real product. When we opened our Santa Ana branch, Nadia Ellery brought crews who already understood Orange County’s soil conditions, the Santa Ana Unified School District’s impact fees, and how the city’s Planning Division interprets rear-yard coverage on 5,000-square-foot lots in Madison Park versus 7,500-square-foot lots in West Floral Park. That matters because an ADU designed without that context often sits in plan check for months.
2. Our Reputation Shows in the Details Homeowners Notice
We don’t ask anyone to trust us blindly. Our Santa Ana homeowners talk specifically about the permit packets we deliver, the photos we send from the footing inspection, and the written change-order policy they signed before work started. The Haven Standard requires evidence on every job, and that means you see what we found, not what we felt about it. A homeowner in Portola Hills recently noted that our pre-construction moisture readings caught a drainage issue that would have cost $4,000 to fix later. We documented it, priced the fix in writing, and handled it before the slab went in.
3. Every Pro on Your Job Meets California’s Requirements
Under Haven Standard Clause 3, Verified Crews, every professional working under our name in Santa Ana is required to hold the license and insurance California requires for their trade. We don’t self-certify; we verify. That includes the electrician who handles your 200-amp service upgrade, the plumber who ties into your existing sewer lateral, and the framer who builds to the structural drawings we stamped. Their license numbers go in your project file, and you can look them up.
4. We Design and Build With Systems That Actually Work Here
We’re not generic builders who’ll figure it out as we go. In Santa Ana’s climate, with its hot, dry Santa Ana winds and occasional winter rains, we specify materials and assemblies that perform. We’ve worked with prefab systems including Cover and Dvele, and we understand where a factory-built module saves time versus where site-built makes more sense for your lot geometry. A homeowner in Tustin with a narrow driveway and overhead power lines needed a Dvele unit craned in from the alley; we mapped that lift before we quoted the price, because Clause 1 of The Haven Standard says the price is flat and written before we start.
5. Your Estimate Is Itemized, Written, and Free
We don’t do verbal ballparks that balloon later. Our Santa Ana estimates break out design, permit expediting, site work, foundation, utility connections, and finish work as separate line items. You’ll see the allowance for your kitchen package, the permit fee estimate based on Santa Ana’s current valuation schedule, and the contingency we hold for unknown conditions. If we don’t hit a line item, you don’t pay it. No surprises means no door upsell, no “while we’re in here” additions, and no scope creep. That’s Haven Standard Clause 5.
6. Our Warranty Is Written, Not Implied
Every Santa Ana ADU we build carries a written workmanship warranty documented in your contract, not a handshake promise that evaporates when the crew moves to the next job. If something we installed fails because of how we installed it, we fix it. The documentation system from Clause 4, Evidence on Every Job, means we have photos and readings of what we actually found and what we actually did. That protects both of us. Nadia Ellery reviews every warranty request personally, because her name is on the trucks.
Our Promise to You
The Haven Standard governs every Ellery ADU Studio branch, and our Santa Ana team operates under it without exception. Clause 1: your price is flat, written, and agreed before work begins. Clause 2: we arrive on schedule, with a real window, a named lead, and a text when we’re en route. Clause 3: verified crews only. Clause 4: photo and written documentation of conditions found and work completed. Clause 5: no surprises, no upsell, no scope creep.
If you’re not satisfied with how we’ve delivered on any clause, we want to know within 48 hours. Nadia Ellery handles escalations directly, and we will make it right or document why we believe we already have. Our pricing transparency commitment means you receive the same itemized format at estimate, contract, and final invoice stages. What you sign is what you pay, unless you request a change and we both sign a written change order first.

AfterFrequently Asked Questions
Most ADU projects fail at the handoff between designer and builder, when each can blame the other for delays or cost overruns. We’re a design-build studio, not a contractor who outsources drawings or a designer who disappears during construction. Since 2015, Ellery has kept design, permitting, and build under one contract with one written price. In Santa Ana specifically, Nadia Ellery’s team understands local zoning overlays, school district fees, and soil conditions that out-of-area builders learn about too late. Call (949) 541-8498 to schedule your free estimate and compare our itemized quote to what you’ve received elsewhere.
Haven Standard Clause 5, No Surprises, includes a satisfaction mechanism: notify us within 48 hours of any concern, and Nadia Ellery will review the documentation from Clause 4 to determine what was specified, what was delivered, and what resolution is appropriate. We fix what we did wrong. We explain what we believe we did right. Either way, you get a written response. Our workmanship warranty covers defects in installation for the term specified in your contract. Call (949) 541-8498 and ask for Nadia if you need to activate this process.
No. Our Santa Ana estimates are free, written, and itemized. We visit your property, measure your lot, check setbacks against Santa Ana’s current zoning code, and deliver a line-item quote that includes design, permitting, site work, construction, and finish allowances. We don’t charge for this because we want you to compare apples to apples with other builders. Call (949) 541-8498 to schedule yours.
Yes. Every professional working under our name in Santa Ana is required to hold the California contractor license and insurance their trade requires. We verify this under Haven Standard Clause 3, and license numbers are available in your project documentation. Ellery ADU Studio operates as an independently owned and operated local branch serving Santa Ana, Tustin, Fountain Valley, Costa Mesa, Garden Grove, Orange, Westminster, Irvine, Huntington Beach, Newport Beach, Fullerton, and Cypress. Call (949) 541-8498 to confirm current licensing status for your specific project type.
We schedule estimate visits during our operating hours: Monday through Friday 7:30 AM to 7:30 PM, Saturday and Sunday 8:00 AM to 6:30 PM. Most Santa Ana homeowners receive an appointment within one week of calling, depending on current project volume. We don’t promise same-day or emergency response for ADU work because ADUs are planned construction, not repairs. What we do promise is a real arrival window, a text when your estimator is en route, and a written quote within 48 hours of the visit. That’s Haven Standard Clause 2. Call (949) 541-8498 to schedule.
