The Ellery ADU Studio Riverside Guarantee
We stand behind every ADU we design, permit, and build in Riverside because we live with the same results you do. Since 2015, we’ve completed 900+ ADUs across the Inland Empire, and every single project started with a written price and ended with a documented photo record of what was built. Our guarantee isn’t a marketing line. It’s The Haven Standard, a set of written clauses that governs how we work before we ever step on your property. When Nadia Ellery and our team commit to your garage conversion in Orangecrest or a new detached ADU in Woodcrest, that commitment is backed by a 365-Day Done Right Promise: if the finished ADU is not built to the permitted drawings, we make it right, in writing, before the first nail goes in. No voicemail queues, no callback tags that evaporate. A live person answers when you call (951) 418-2910, and the same team that priced your job sees it through final inspection.
What’s Covered
- Workmanship to the permitted drawings. Every joint, finish, and connection is built to match the approved permit set, not a loose interpretation, and our 365-Day Done Right Promise means we return to correct anything that deviates.
- Written price before any work starts, period. Under Haven Standard Clause 1, you receive a line-item written quote before construction begins; the words “call for a quote” do not exist in our process, and the scope is locked at signing under Clause 5 (No Surprises).
- Documented photo record on every visit. You receive dated, geotagged evidence of what our crew found and what they did, not a summary of how it felt, so there’s no dispute about site conditions or completed work.
- Parts and material handling with brand fluency. We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie within the same single contract, so material accountability never gets passed between a separate designer and builder.
- Site protection and daily cleanup. Your existing home, landscaping, and access paths are treated as part of the scope; our background-checked, uniformed crews leave the work zone secure each day, with photo documentation to prove it.
- On-time milestone arrival. We schedule pre-construction meetings, inspection appointments, and material deliveries in the sequence they actually happen, and when weather or permit delays hit (they do, especially during Riverside’s Santa Ana wind season), we tell you the revised date before you have to ask.
- Honest pricing with no door-side upsells. The price at signing is the price at final walkthrough; no scope creep, no “while we’re here” additions, no pressure to expand the job once we’re on site.
- Free Second Opinion on any written estimate. Already have a quote in hand? We’ll review it line by line, tell you what’s reasonable for the Riverside market and what might be missing, at no charge.
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, our crew documents every visit with photos you can access. At final walkthrough, we review the completed ADU against the permitted drawings together. If a finish doesn’t match, a connection is exposed, or a dimension is off, we note it on the spot and schedule the correction. Under our 365-Day Done Right Promise, that window extends a full year past completion, because some issues (settling, seasonal expansion in Riverside’s 100-degree summers, sealant performance) don’t show on day one.
There’s no arbitration clause, no “reasonable wear and tear” escape hatch, no transfer to a warranty administrator in another state. You call (951) 418-2910, a live person answers, and we dispatch the same trade that did the original work. If we built it, we stand behind it. Nadia Ellery has handled the make-it-right calls personally since 2015, and that hasn’t changed with 900 projects or with growth into the broader Haven network. The promise is in writing before your project starts because a verbal “we’ll take care of it” isn’t a guarantee you can enforce.
Licensed & Insured Backing
A guarantee is only as solid as the company behind it. Ellery ADU Studio Riverside is licensed and insured, which means there’s a regulatory body that verifies our qualifications, an insurer that stands behind our work, and a bond that protects your investment if the unexpected occurs. For a Riverside homeowner spending $80,000-$180,000 on a garage conversion or $150,000-$350,000 on a new detached ADU, that’s not paperwork. It’s the difference between a promise you can collect on and one you can’t.
Our license number appears on every page of this site because we want you to verify it, not just trust us. The California Contractors State License Board maintains our standing; we maintain our insurance without lapses. When we pull permits for your ADU in Riverside’s Arlington Heights or La Sierra neighborhood, the city inspector knows our license history. When we coordinate with Southern California Edison for utility tie-ins or the Western Municipal Water District for sewer connections, those agencies deal with a credentialed entity, not a project-by-project operator. That continuity matters when your project spans six to fourteen months from design through final inspection.
Being insured and bonded also protects you during the build itself. If a crew member is injured on your property, our workers’ compensation coverage responds. If an excavation for site prep hits an unmarked line, our general liability responds. You don’t navigate those claims, and they don’t become liens against your property. We’ve seen Riverside homeowners learn this distinction the hard way with unlicensed operators who offered a lower price and disappeared when the real costs arrived. Our pricing includes the full cost of doing business the right way, and we put that in writing under Haven Standard Clause 1 so you know what you’re paying for before you commit.
What Our Guarantee Means for Your Project
Every ADU in Riverside faces the same regional realities: expansive clay soils in the Arlanza and Victoria neighborhoods, summer temperatures that stress HVAC sizing, and a permitting process through the City of Riverside’s Planning Department that rewards complete, accurate submittals and penalizes incomplete ones. Our guarantee is designed for these specifics. We don’t promise faster permits than the city delivers; we promise a complete, code-compliant submittal the first time so you don’t lose weeks to corrections. We don’t promise your ADU will cost less than your neighbor’s; we promise a written price that doesn’t change once work starts, so you can plan your financing with certainty.
The 900+ ADUs we’ve designed, permitted, and built since 2015 include garage conversions in the Canyon Crest hills where foundation work was more complex than expected, new detached units in Woodcrest where setback variances required neighbor notification, and junior ADUs in the Eastside where parking relief calculations got us under the square-footage threshold. In each case, the written price held, the photo record documented the challenge, and the Done Right Promise covered the correction when needed. That’s what “we stand behind our work” means at Ellery ADU Studio Riverside. Not perfection on day one, but accountability every day after.
