The Ellery ADU Studio Santa Clarita Guarantee
We stand behind every ADU we design, permit, and build in Santa Clarita with a single written promise: if the finished unit is not built to the permitted drawings, we make it right. That’s the 365-Day Done Right Promise, and it’s in your contract before the first shovel hits dirt. Since 2015, we’ve delivered 900+ ADUs across Los Angeles County with a written price locked at signing, a documented photo record from every site visit, and no change orders hiding in the fine print. In Santa Clarita’s competitive ADU market, where garage conversions in Newhall and detached units in Valencia face distinct soil, setback, and fire-zone requirements, our guarantee means the same thing on every job: the drawings match the build, the build matches the permit, and you know exactly what you’re paying before work starts.
What’s Covered
- Workmanship to the permitted drawings. Our 365-Day Done Right Promise covers the full scope of construction against the approved permit set; if a wall is out of plumb, a window is misaligned, or a finish doesn’t match the spec sheet, we return and correct it at our cost.
- Parts and material handling with full documentation. Every delivery, every substitution, every field change is photographed and logged; you receive the photo record, not a verbal summary, so there’s no dispute about what arrived and what was installed.
- Site cleanup as a line item, not an afterthought. Our crews leave the work area broom-clean at the end of each phase; in Santa Clarita’s hillside neighborhoods like Sand Canyon and Bouquet Canyon, where dust and debris create genuine fire hazards, this isn’t courtesy, it’s compliance.
- Scheduled arrival windows we honor. We confirm appointments by text and call if traffic on the 14 or 5 delays us; your time matters, and our live dispatch team has the authority to reroute crews in real time.
- Honest pricing locked at signing under Haven Standard Clause 1. The written price before work starts is not an estimate, it’s a commitment; no door-side upsells, no “we found something unexpected” add-ons, no scope creep disguised as necessary discovery.
- Prefab and modular system coordination. When we specify Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or James Hardie systems, the single contract covers both the manufacturer’s delivery and our integration with Santa Clarita’s foundation, utility, and inspection requirements.
- Permit compliance through final inspection. We pull permits, schedule inspections, and correct any city-identified deficiencies; if Santa Clarita Building & Safety flags an issue, we handle the revision and reinspection without passing administrative costs to you.
Our Satisfaction Promise

If something isn’t right, we fix it. That’s the entire process.
Here’s how it works in practice. During construction, you receive a documented photo record after every site visit, timestamped and annotated with what was found and what was done. If a photo raises a question, you call (747) 294-4817 and a live person answers, 24 hours a day. No voicemail queue, no callback that doesn’t materialize. We review the image with you, schedule a site walk if needed, and determine whether the issue is a deviation from the permitted drawings or a clarification of the spec.
If it’s a deviation, we correct it under the 365-Day Done Right Promise. If it’s a clarification, we explain the trade’s real vocabulary and show you the governing code or manufacturer specification. In either case, you get a written resolution, not a verbal assurance. We’ve applied this process to garage conversions in Saugus where existing slabs needed regrading, to detached ADUs in Canyon Country where Santa Clarita’s hillside grading ordinances triggered unexpected geotech requirements, and to interior conversions in Valencia where HOA architectural review boards demanded additional documentation. The mechanism is the same: identify, document, correct, confirm.
Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing. If we encounter concealed conditions, we photograph them, explain the options, and quote any change in writing before proceeding. You approve the change or we work around it. There is no scenario where work continues and the bill arrives later.
Licensed & Insured Backing
A guarantee is only as solid as the company behind it. Ellery ADU Studio Santa Clarita is licensed and insured, with background-checked, uniformed technicians and crews whose credentials are verified, not merely claimed. In Santa Clarita, where ADU construction triggers state building code, local fire-safe regulations, and utility interconnection requirements, licensing isn’t a marketing checkbox. It’s the mechanism that lets us pull permits, schedule inspections, and stand behind our work with enforceable obligations.
Insurance and bonding protect you against the risks that licensing alone doesn’t cover: property damage during excavation in rocky Valencia soil, worker injury on a steep Sand Canyon lot, or subcontractor default on a complex utility trench across a Bouquet Canyon easement. When you sign our single-contract design-build agreement, you’re contracting with one entity that carries the full risk stack, not a designer who blames the builder or a builder who blames the designer. That’s the point of our model: one contract, one written price, one party responsible for making it right.
Nadia Ellery has operated this studio since 2015 under that structure. The Haven Standard, Clause 1 through Clause 5, governs every project. And the live person who answers your call at (747) 294-4817 has the authority to activate the guarantee, schedule the correction, and document the resolution. No escalation queue, no “someone will call you back.”
Free Second Opinion: Test Our Guarantee Against Any Written Estimate

If you already have a written estimate from another Santa Clarita ADU contractor, we’ll review it against our standard at no charge. We’ll identify where pricing is vague, where scope is undefined, and where guarantees are implied rather than written. There’s no obligation to hire us. The point is to show you what a fully guaranteed ADU project actually looks like on paper before you commit.
Call (747) 294-4817 to schedule your free estimate or second opinion. Every project receives a written price before work starts, a documented photo record on every visit, and the 365-Day Done Right Promise in writing.
