The Ellery ADU Studio Menifee Guarantee
We stand behind every ADU we design, permit, and build in Menifee with three promises that are in writing before your project starts. First, under Haven Standard Clause 1, you receive a written price before any work begins - no “call for a quote,” no ballpark that balloons later. Second, our crews document every visit with a photo record showing what we found and what we did, not a summary of how it felt. Third, our 365-Day Done Right Promise: if the finished ADU is not built to the permitted drawings, we make it right. Nadia Ellery put these terms in place when she opened the studio in 2015, and they’ve governed all 900-plus ADUs we’ve completed since.
What’s Covered
- Workmanship guarantee. Every ADU in Menifee - whether it’s a garage conversion off McCall Boulevard, a new detached unit near the Menifee Lakes, or a junior ADU tucked into a Sun City footprint - is built to the permitted drawings, and we back that construction quality for a full year after completion.
- Parts and materials handling. We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie under the same single contract, so if a panel, fixture, or system component arrives damaged or out of spec, we handle the replacement - not you, not a separate vendor.
- Site cleanup and protection. Your existing home and yard stay protected during construction; our background-checked, uniformed crews leave the work area broom-clean at the end of each phase, with photo documentation of the condition we found and the condition we left.
- Permit and inspection coordination. We pull all permits and schedule all inspections for your Menifee ADU project, and we do not consider the job complete until the final inspection is passed and the certificate of occupancy is issued.
- Honest, upfront pricing with zero scope creep. Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing; no door-side upsells, no “while we’re here” additions, no change orders unless you request them in writing.
- Live answer, every call. A real person answers our phone 24 hours a day - no voicemail queue, no callback promise that doesn’t materialize when you’re trying to reach us about your Menifee project.
Our Satisfaction Promise

If something isn’t right, we make it right. Here’s how that works in practice.
During construction, you receive a documented photo record on every visit. These aren’t progress summaries - they’re timestamped evidence of what our crew found and what they did. If a wall framing detail doesn’t match the approved permit set, you see it in the photos, and we correct it before drywall goes up. If the finished ADU doesn’t match the permitted drawings, our 365-Day Done Right Promise kicks in: we return, we fix it, and we document that fix the same way.
There’s no arbitration clause, no “reasonable wear and tear” carve-out that lets us off the hook for construction defects. The promise is simple - built to the drawings, or we make it right - and it’s in your contract before the first shovel hits the dirt in Menifee. Nadia Ellery reviews every warranty call personally; she’s the same person who approved your written price under Clause 1, and she’s the one who ensures the resolution matches the original commitment.
We also offer a Free Second Opinion on any written estimate you already have in hand. Bring us another contractor’s scope and pricing, and we’ll tell you what’s included, what’s missing, and where the risks hide - no charge, no obligation to hire us.
Licensed & Insured Backing
The written guarantees only matter if there’s a real business standing behind them. Ellery ADU Studio Menifee is licensed and insured, with coverage that protects your property during construction and workers’ compensation that covers our crews on your site. This isn’t a handshake operation or a permit-runner who disappears after plans are stamped - we’ve been a design-build studio since 2015, with 900-plus ADUs completed from initial sketch through final inspection.
Your contract is with one entity that handles ADU Design & Permitting, Garage Conversion ADU, New Detached ADU, Junior ADU & Interior Conversion, and ADU Site Prep & Utilities. That matters because if the designer and builder are separate companies, each can blame the other when setbacks don’t match, utility tie-ins fail, or the slab cracks. Our one-contract model means one throat to choke - ours - and our insurance backs that single point of accountability.
We don’t publish our license number here as a flex; we put it on every page of this site because it’s verifiable, not just claimed. You can check it with the California Contractors State License Board. You can confirm our insurance certificates. And when you’re ready to move forward on your Menifee ADU, you can call (951) 528-2967 - a live person answers, 24 hours a day - to schedule your free estimate with a written price before any work starts.
Common Questions About Our Guarantee

What does the 365-Day Done Right Promise actually cover?
It covers construction that does not match the permitted drawings. If the finished ADU deviates from what was approved by the city of Menifee - wall placement, ceiling height, window size, utility routing - we return and correct it at no charge. Call (951) 528-2967 to discuss your specific project; estimates are free.
Will the price change once work starts?
No. Under Haven Standard Clause 1, your written price is locked before work begins. Clause 5 (No Surprises) prevents scope creep. The only way the price changes is if you request a change in writing. Call (951) 528-2967 for your written estimate.
Do you pull the permits, or do I?
We pull all permits and schedule all inspections. It’s included in our single-contract scope, and we don’t consider the job complete until final inspection is passed. Call (951) 528-2967 to start the process.
What if I already have an estimate from another Menifee ADU contractor?
Bring it in. Our Free Second Opinion compares their scope to ours, line by line, and flags what’s missing or risky - no charge, no obligation. Call (951) 528-2967 to schedule.
How do I know the crew working on my property is legitimate?
Our technicians and crews are background-checked and uniformed, and our license number appears on every page of this site for verification. You’re welcome to confirm it with the CSLB before we start. Call (951) 528-2967 with any questions.
