The Ellery ADU Studio Rialto Guarantee
We stand behind every ADU we design, permit, and build in Rialto with something most contractors won’t put on paper. Under the Haven Standard, every project starts with a written price locked before work begins and ends with a 365-Day Done Right Promise backed in writing. If the finished ADU doesn’t match the permitted drawings, we make it right. No chargebacks, no blame-shifting between designer and builder, no “that’s not my department.” We’ve completed over 900 ADUs since 2015, and every single one left with a documented photo record and a written scope. That’s the guarantee Nadia Ellery built this studio on.
What’s Covered
- Workmanship to the permitted drawings. Our crews build what the city approved, not what seemed easier that morning. If the finished ADU deviates from the permit set, Clause 5 of the Haven Standard triggers our make-it-right protocol.
- Written price before any work starts. Haven Standard Clause 1 requires a line-item quote in writing before the first shovel hits dirt. The words “call for a quote” do not appear anywhere in our process because they don’t appear in our values.
- Documented photo record on every visit. You receive evidence of what we found and what we did, not a summary of how it felt. Foundation pour, framing inspection, utility tie-in - each stage is photographed and shared.
- Site condition at handoff. We don’t disappear leaving nail strips and drywall dust. The property is left broom-clean, with all construction debris hauled per Rialto’s waste disposal requirements.
- On-time milestone arrivals. Inspection windows matter in Rialto. San Bernardino County schedules fill fast, and a missed rough-in inspection can push your project two weeks. We arrive when we say we will.
- Honest pricing with zero scope creep. Under Clause 5 (No Surprises), the scope is locked at signing. No door-side upsells, no “while we’re here” additions, no change orders born of vague initial quotes.
- Prefabricated system coordination. When your project specifies Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or James Hardie systems, we warranty our integration work, not just the box that arrived on the truck.
- Free Second Opinion on any written estimate. Already have a quote in hand? We’ll review it item by item, no charge, no obligation. We’ve caught $8,000 slab omissions and phantom “Rialto surcharge” line items that had no basis in actual city fees.
Our Satisfaction Promise
If something’s not right, we don’t debate whose fault it is. We fix it. The 365-Day Done Right Promise means that for a full year after final inspection, any deviation between the built ADU and the permitted drawings is our responsibility to correct. Here’s how the process works: you call (951) 476-1467, a live person answers, and we schedule a site review within 48 hours. Nadia Ellery or a senior project lead walks the unit with the original permit set in hand. If we confirm a discrepancy, we submit a revised scope within 72 hours and complete the correction on our timeline, not yours. No deductibles, no “normal settling” excuses, no routing you between a designer who blames the framer and a framer who blames the soils. The single-contract design-build model exists precisely to eliminate that runaround. We’ve honored this promise on slab re-pours in Rialto’s Muscoy-adjacent clay soils, on roof pitch corrections where the prefab module didn’t match the site grade, and on window relocations where the city’s final inspection flagged egress clearances we should have caught earlier. Each time, the client received a written correction plan and updated photo record. Satisfaction isn’t a feeling we claim you have. It’s a condition we document and deliver.
Before
AfterLicensed & Insured Backing
A guarantee is only as solid as the business behind it. Ellery ADU Studio Rialto is licensed and insured, with background-checked, uniformed technicians whose credentials are verified, not merely claimed. In Rialto’s construction market, where unpermitted garage conversions get red-tagged every month and fly-by-night operators leave homeowners with uninsurable structures, licensing is the floor, not the ceiling. Insurance protects your property during construction. Our bonding backs the financial commitments we make. But the real security is operational: we’ve been in business since 2015, completed over 900 ADUs, and maintained the same single-contract model that prevents the designer-builder finger-pointing that destroys most projects. When Nadia Ellery signs your contract, she’s signing as both designer and builder. There’s no entity to dissolve, no subcontractor to disappear, no shell company between you and the person accountable. The Haven Standard clauses, the written price, the photo record, and the 365-Day Done Right Promise all flow from that single point of responsibility. That’s the guarantee. Everything else is paperwork that makes it enforceable.
How the Haven Standard Protects Your Investment
Every Ellery ADU Studio project in Rialto runs on five clauses that govern how we work, not just what we promise.
Clause 1: Written Price Before Work Starts. Your quote arrives as a line-item document with no placeholder figures. Foundation, framing, electrical, plumbing, finishes, permits, and inspections - each listed separately so you see where your money goes. Once signed, that total doesn’t move unless you request a change and sign a written amendment.
Clause 5: No Surprises. The scope is locked at contract execution. Our crews don’t arrive with “we noticed your panel needs upgrading” add-ons that weren’t in the original estimate. If we missed something during site walkthrough, that’s our planning error, not your unexpected cost.
Photo Record Protocol. Every visit generates timestamped images uploaded to your project file. Pre-construction conditions, footing depths, rebar placement, insulation R-values, final paint coverage - you see what we saw, not our interpretation of it.
365-Day Done Right Promise. Active for 365 days from final inspection. Covers workmanship deviations from permitted drawings. Does not cover homeowner modifications, tenant damage, or normal material weathering. Triggered by written request, resolved by written plan.
Live Answer Guarantee. Call (951) 476-1467 any time. A person answers. No voicemail queue, no “we’ll call back within 24 hours” that stretches to 72. For active projects, this means real-time answers about inspection schedules, material deliveries, and crew arrivals. For warranty claims, it means immediate triage, not a ticket number.
What “Make It Right” Looks Like in Practice
In Rialto’s North Rialto neighborhood, we converted a 22-by-24-foot garage into a Junior ADU. The permit set specified a 36-inch entry door for accessibility compliance. During framing, the crew installed a 32-inch door from a batch already on-site. Our final walkthrough caught the deviation before inspection, but the client spotted it first in the photo record. We removed the incorrect door, ordered the proper unit, and completed the swap at no charge - including the re-inspection fee. The correction appeared in the final photo record with a notation referencing the original permit drawing. That’s Clause 5 enforcement. That’s the 365-Day Done Right Promise in action, even pre-inspection. We don’t wait for the city to catch our errors. We catch them, document them, and correct them.
In a detached ADU project near Rialto’s historic downtown, the site prep revealed unexpected fill soil that the initial soils report hadn’t flagged. Rather than pour a standard footing and hope, we stopped work, commissioned a supplemental soils analysis, and revised the foundation specification to a pier-and-grade-beam system. The client received a written amendment showing the original slab price, the pier system price, and our absorption of the soils testing cost. The project finished three weeks later than originally scheduled, but the foundation is warranted against differential settlement. A cheaper contractor would have poured and prayed. We don’t build that way in Rialto’s variable soil conditions.
Your Role in the Guarantee
The Haven Standard works both ways. We ask clients to: maintain access for scheduled inspections, respond to design review comments within 72 hours to avoid permit delays, and notify us immediately of concerns rather than waiting until the final walkthrough. The photo record is shared in real time; reviewing it promptly lets us correct issues while the relevant crew is still on-site, not after they’ve moved to the next Rialto project. The written price depends on the scope remaining stable; significant changes requested mid-project require a signed amendment. And the 365-Day Done Right Promise requires written notification with photo documentation of the concern, so we can respond with specificity rather than speculation.
Ready to Talk Guarantee in Person?
Every guarantee clause reads stronger when you understand how it applies to your specific property. Call (951) 476-1467 to schedule your free estimate. We’ll walk your site, identify the relevant Rialto zoning and setback requirements, and return a written line-item quote with no obligation. Already have another contractor’s estimate in hand? We’ll provide a Free Second Opinion, item by item, clause by clause. Nadia Ellery has reviewed quotes that buried $6,000 utility trenching costs in “allowance” language and others that omitted fire separation requirements for garage conversions entirely. The Haven Standard exists because we’ve seen what happens when it doesn’t.
