The Ellery ADU Studio Irvine Guarantee
We’re Nadia Ellery and the team at Ellery ADU Studio Irvine, and we’ve been designing, permitting, and building ADUs in this market since 2015. When we say we stand behind our work, we mean it in writing, not in a handshake that evaporates when the job gets tough. Every project we take on in Irvine is governed by The Haven Standard: a written price locked before any work starts, a documented photo record from every site visit, and our 365-Day Done Right Promise. If the finished ADU doesn’t match the permitted drawings, we make it right. No dispute about what was promised. No “call the other guy.” One contract, one accountable team, and a live person answering the phone at (657) 233-9738 any hour you need us.
What’s Covered
- Workmanship that matches the permitted drawings. Our 365-Day Done Right Promise means if the built ADU deviates from what the city approved, we correct it at our expense, not yours. This isn’t a “satisfaction” loophole - it’s a structural, measurable standard tied to the permit set you signed off on.
- Parts and material handling with full traceability. We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, and we document what arrives, what gets installed, and what condition it’s in. You receive that photo record, not a verbal summary.
- Site cleanup that respects your property. Our crews are background-checked and uniformed, and they leave the work area broom-clean at the end of each phase. The photo record shows before and after - evidence, not assurance.
- Scheduled arrival with real accountability. We don’t give you a four-hour window and disappear. When we set a time for site work in Irvine, we show up, and if a delay is unavoidable, a live person calls you - no voicemail queue, no callback that never comes.
- Honest pricing with zero scope creep. Under Haven Standard Clause 1, every project carries a written price before any work begins. Under Clause 5 (No Surprises), that scope is locked at signing. No door-side upsells, no “we found something extra” pressure. The words “call for a quote” do not appear anywhere on our site because they don’t apply to how we operate.
Our Satisfaction Promise
If something’s not right, we want to hear about it fast. Call (657) 233-9738 - a live person answers 24/7, no exceptions. We’ll schedule a site review within 48 hours, compare the built condition against the permitted drawings and your signed scope, and present a written correction plan with a timeline. If the issue falls under our 365-Day Done Right Promise, we execute that plan at no additional charge. If it’s a preference change outside the original scope, we’ll quote it separately with the same written-price discipline, and you decide before we proceed. We’ve completed 900+ ADUs since 2015, and every one left the client with a documented photo record of what was found and what was done. That documentation protects both of us. It means there’s no argument about whether the slab was 4 inches when we started, or whether the electrical panel had capacity for the subfeed. We fix what we got wrong. We document what we found. And we don’t hide behind a designer-builder split - our one-contract model means the same team that drew your ADU builds your ADU, so no one can point fingers when something needs attention.
Licensed & Insured Backing
A warranty is only as solid as the company behind it. We’re licensed and insured, which means our work carries the structural and financial backing that protects your property and your investment. In Irvine’s permit environment, an unlicensed operator can leave you with approved drawings that no legitimate builder will touch, or worse, completed work that fails inspection and can’t be legally occupied. Our license status is verified, not merely claimed, and our insurance coverage means that if the unexpected happens - property damage, injury on site, a subcontractor dispute - there’s a policy and a process, not a personal promise that may or may not survive a court date. The Haven Standard requires this transparency because we’ve seen what happens when homeowners in Orange County gamble on a lower bid from an unverified operator. The “savings” evaporate when the city red-tags the structure or the contractor disappears mid-project. Our licensing and insurance aren’t marketing badges. They’re the operational foundation that makes the 365-Day Done Right Promise enforceable, the written price meaningful, and your ADU buildable from first sketch to final certificate of occupancy.
Free Second Opinion: Know What You’re Signing
Already have a written estimate from another Irvine ADU builder? Bring it to us. We’ll review the scope, the line items, and the permit strategy - free of charge. We’ll tell you what we see: whether the foundation allowance matches your actual soil conditions, whether the electrical service upgrade is included or buried in a contingency, whether the prefab brand specified can actually deliver to your lot in the quoted timeline. Sometimes we confirm you’re getting a fair deal. Sometimes we catch a $15,000 gap between what was promised and what the city will require. Either way, you leave with clearer information and no obligation. Call (657) 233-9738 to schedule your free second opinion.
How the Haven Standard Protects Your Project
We’ve built our entire operation around five clauses that govern every ADU we touch in Irvine. Here’s what they mean in practice:
- Clause 1 - Written Price Before Any Work Starts. You’ll never hear “we’ll figure it out as we go.” Your contract specifies every major line item, from the permit set to the final inspection, and that total is locked before we break ground.
- Clause 5 - No Surprises. The scope at signing is the scope at completion. If we encounter a genuine unknown - say, an unmapped utility line during site prep - we document it, stop work, and present a written change order with options. You approve in writing before we proceed.
- Documented Photo Record on Every Visit. Our technicians photograph what they find and what they do. You receive these images, not a narrative summary. In Portola Springs, we once found a client had been told their existing garage slab was “probably fine” by another builder; our photo showed a 3-inch slab with no rebar, below code for conversion. That documentation saved them from a $9,000 foundation surprise six weeks into construction.
- 365-Day Done Right Promise. If the finished ADU doesn’t conform to the permitted drawings, we correct it. This is structural, not cosmetic - we’re talking wall placement, ceiling height, window egress compliance, not paint touch-ups you’re free to handle yourself.
- Live Person, 24/7. Questions don’t keep business hours. Whether you’re in Northwood at 10 PM worrying about a permit comment letter, or in Woodbridge at 6 AM before a site walk, a real human answers (657) 233-9738.
What We Ask of You
A guarantee works both ways. We ask that you review your permit set before signing - the drawings we submit to Irvine’s planning department are the drawings we’ll build from. We ask that you communicate concerns promptly, while they’re small and fixable, not after months of silent frustration. And we ask that you hold us to the same standard we hold ourselves: if we say we’ll do something, check that we did, and call us if we didn’t. The photo record makes this easy. The written scope makes it unambiguous. The live phone line makes it immediate.
Ready to Start With Confidence?
Whether you’re converting a garage in Turtle Rock, building a detached ADU in Orchard Hills, or exploring a junior ADU in Westpark, we’ll give you a written price, a clear permit strategy, and a team that doesn’t vanish when the project gets complex. Call (657) 233-9738 to schedule your free estimate. Estimates are free, pricing is written, and the person who answers the phone can actually help you.
