The Ellery ADU Studio Santa Ana Guarantee
We stand behind every ADU we design, permit, and build in Santa Ana with a single, non-negotiable standard: the work must match the permitted drawings, the price must match the written quote, and the record must show what happened, not what we remember. Since 2015, we’ve completed more than 900 ADU projects across Southern California, and every one began with a written price and ended with a documented photo record. For Santa Ana homeowners, this means no gap between what was promised and what was delivered. If the finished ADU is not built to the permitted drawings, we make it right. That’s not a slogan. It’s Haven Standard Clause 5, and it’s in writing before your project starts.
What’s Covered
- Workmanship to the permit set. Every wall, connection, and finish must match the drawings that passed Santa Ana Planning and Building Safety. If it doesn’t, we correct it under our 365-Day Done Right Promise.
- Parts and materials as specified. We don’t substitute without written approval. If your contract specifies James Hardie siding or a Dvele modular system, that’s what arrives. Any change gets documented, not assumed.
- Site condition on departure. Our crews leave the work area broom-clean at minimum. For active construction sites, that means clear pathways, secured materials, and no debris that creates a hazard for your household or your neighbors.
- Appointment windows we keep. We confirm arrival times by text the evening before. If we’re running behind, we call. The live person answering our phones at (949) 541-8498 can tell you where your crew is, not just take a message.
- The price on the page is the price you pay. Haven Standard Clause 1 requires a written price before any work starts. No change orders for “discovered” conditions that a competent site evaluation should have caught. No door-side upsells. The scope is locked at signing.
- Photo documentation on every visit. You receive evidence of what we found and what we did, not a summary of how it felt. Foundation condition, existing slab thickness, utility locations - it’s in your record, dated and described.
Our Satisfaction Promise

If something’s not right, we fix it. The process is deliberate and specific.
First, you tell us what doesn’t match the permitted drawings or the written scope. We don’t ask you to prove it with a camera or a lawyer. We send the same crew lead or project manager who knows your site, not a new face reading notes.
Second, we photograph the issue the way we document everything else. You see what we see. No interpretation gap.
Third, we correct the work and re-inspect against the permit set. If a city re-inspection is required, we pull the permit amendment and meet the inspector. You don’t coordinate between designer and builder because we’re the same contract. That’s the point of our one-contract design-build model.
The 365-Day Done Right Promise covers the full year after final inspection because some issues don’t appear in the first 30 days. Settlement cracks, door alignment shifts, trim movement - Santa Ana’s warm-dry to occasional-wet climate cycle reveals things that a single-season warranty misses. We’ve seen it in the Delhi neighborhood, where older slabs move differently than new ones, and in Floral Park, where mature tree roots affect drainage patterns over time. A year lets the structure go through enough cycles to prove itself.
If we can’t make it right to your satisfaction, Haven Standard Clause 5 spells out the specific remedy. You have it in writing before the first shovel hits dirt.
Before
AfterLicensed & Insured Backing
A guarantee is only as solid as the business standing behind it. Ellery ADU Studio Santa Ana is state-licensed and carries the insurance and bonding required for design-build ADU work in Orange County. That matters because an unlicensed operator can promise anything and disappear. A licensed contractor has a record with the CSLB that you can verify, a bond that provides recourse, and insurance that protects your property if something goes wrong during construction.
Our license number appears on every page of this site because we want you to check it. Nadia Ellery built this studio on the principle that verification beats trust-me. The license, the bond, the general liability policy - these are the real guarantees behind the paperwork. They mean that if a subcontractor gets injured on your Santa Ana property, you’re not exposed. They mean that if a design error makes it to construction, the professional liability coverage responds. They mean that when we say “we’ll make it right,” there’s a regulated business with assets and a reputation still on the line twelve months later.
We’ve operated continuously since 2015. That’s not longevity for its own sake. It’s evidence that we finish projects, pass inspections, and maintain the financial stability to honor promises. In Santa Ana’s ADU market, where some entrants are here for the boom and gone for the bust, that continuity is its own form of guarantee.
How to Use Your Guarantee

The guarantee activates the moment you sign, not at final inspection. From day one, Haven Standard Clause 1 protects your pricing. During construction, the photo record protects your understanding of what’s happening. After completion, the 365-Day Done Right Promise protects your investment.
