The Ellery ADU Studio Thousand Oaks Guarantee
Every ADU we design, permit, and build in Thousand Oaks comes with a promise you can hold in your hand. Under the Haven Standard, your project gets a written price before any work starts, a documented photo record on every visit, and our 365-Day Done Right Promise backed in writing. If the finished ADU is not built to the permitted drawings, we make it right. No exceptions, no finger-pointing between designer and builder. We’re independently owned and operated here in Thousand Oaks, and we’ve delivered on this guarantee across 900+ ADUs since 2015.
What’s Covered
- Workmanship to the permitted drawings. Our 365-Day Done Right Promise means if the finished ADU doesn’t match what was approved by the city of Thousand Oaks, we return and correct it at our expense.
- Written price locked at signing. Under Haven Standard Clause 1, the price you sign is the price you pay. No door-side upsells, no scope creep, no “we found something extra” surprises after work begins.
- Documented photo record on every visit. You receive evidence of what we found and what we did, not a summary of how it felt. These photos become part of your project file and warranty documentation.
- Permit compliance and inspection passage. We pull permits for every project and see them through final inspection. If a Thousand Oaks building inspector flags something we installed, we handle the correction and re-inspection.
- Honest upfront pricing with no hidden fees. We don’t do “call for a quote.” Every line item is itemized in writing before you sign, including contingency allowances for conditions we can’t see until we open walls.
- Clean job sites and respectful crews. Background-checked, uniformed technicians treat your property like it’s their own neighborhood. We leave the site broom-clean after every phase.
- Live person availability. A real human answers our phones 24/7. No voicemail queue, no callback promise that doesn’t materialize when you’re trying to reach us about your project.
- Free Second Opinion on any written estimate. Already have a quote from another Thousand Oaks ADU contractor? Bring it to us. We’ll review it item by item and tell you what we see, no charge.
Our Satisfaction Promise
If something’s not right, we want to hear about it fast. Call us at (424) 395-4555 and a live person will pick up, day or night. We’ll schedule a site visit within 48 hours, review the issue against your permitted drawings and photo record, and present a written correction plan with a timeline. Most fixes happen within one week. If we built it, we stand behind it. The 365-Day Done Right Promise covers any workmanship or materials deviation from the approved plans, not just “defects” narrowly defined. We don’t disappear after final inspection. Nadia Ellery personally reviews every make-it-right case to confirm the resolution matches the original design intent. Your final walkthrough isn’t the end of our relationship; it’s the beginning of our accountability period.
Licensed & Insured Backing
Licensing and insurance aren’t decorations on our website; they’re the financial backbone that makes our guarantees real. Our license number appears on every page of our site because we want you to verify it with the California Contractors State License Board, not just take our word. Being insured and bonded means if something goes wrong on your Thousand Oaks property, there’s coverage that protects you, not just us. Since 2015, we’ve maintained continuous coverage across every project phase, from design through final inspection. That continuity matters because an ADU spans 8 to 14 months in Thousand Oaks, and a policy that lapses mid-project leaves you exposed. We don’t let that happen. When you sign with Ellery ADU Studio, you’re signing with a licensed entity that can be held accountable, not a fly-by-night operator who vanishes when the city asks questions.

What “Done Right” Means in Practice
We’ve seen what goes wrong in Thousand Oaks ADU projects where the designer never talked to the builder. A foundation gets poured to the wrong elevation because the civil plan didn’t match the architectural. A window gets installed where the structural engineer specified a shear wall. A kitchen rough-in misses the gas line by four feet because the MEP designer assumed a different cabinet layout. Our one-contract model prevents these failures by design. Nadia Ellery coordinates every trade through a single workflow, so the concrete crew reads the same foundation detail the architect drew, and the electrician sees the cabinet elevation the interior designer specified. When we say “done right,” we mean built to the drawings that Thousand Oaks approved, not “close enough” or “looks fine.”
Prefab and Modular Guarantees
For clients choosing prefab or modular systems, we extend the same accountability. We specify and coordinate Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie systems within our single contract. That means if the factory module arrives with a finish mismatch or a structural connection that doesn’t match the approved set, we handle the manufacturer coordination and site correction. You don’t get passed off to a brand’s warranty department while your backyard sits half-finished. Our 365-Day Done Right Promise covers the integration work, the utility connections, and the finish carpentry that turns a delivered module into a permitted, inspected ADU in Thousand Oaks.
Questions Homeowners Ask About Our Guarantee
What if I find a problem after the 365 days?
We still answer the phone. The 365-Day Done Right Promise covers workmanship deviations from permitted drawings; manufacturer warranties on appliances, fixtures, and systems run independently and are transferred to you at closeout. Call (424) 395-4555 and we’ll tell you exactly which warranty applies to your concern.
Will the price ever change once we sign?
Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing. The only price changes come from owner-requested additions or conditions truly unforeseeable before work starts, and those require a written change order you approve before we proceed. No hidden conditions, no surprise line items.
What documentation do I receive at project close?
Your closeout packet includes the final permit set with city approval stamps, the complete photo record from every visit, your written 365-Day Done Right Promise, and a line-item final invoice matching your original quote. Everything in one place, everything in writing.
How do I verify your license and insurance?
Our license number appears on every page of this site. Run it through the CSLB lookup yourself. We carry general liability and workers compensation coverage, and we’ll provide a certificate of insurance naming you as additional insured upon request. No hesitation, no runaround.
What happens if there’s a dispute about whether something is “done right”?
We refer to the permitted drawings, the photo record, and the written scope. These three documents resolve nearly every question without argument. In the rare case they don’t, we agree in writing to binding arbitration under California law, not expensive litigation. We’ve never had to use it.
