Why Moreno Valley Homeowners Choose Ellery ADU Studio Moreno Valley for ADU
Since 2015, Ellery ADU Studio has completed over 900 ADUs across California with a single rule: every job gets a written price before anyone picks up a hammer. Our Moreno Valley branch, led by Nadia Ellery, brings that same standard to Riverside County. Homeowners here compare us to other builders, and they keep choosing us because we put the price, the permit timeline, and the warranty in writing before work starts. That’s Haven Standard Clause 1, and it’s how we’ve worked since the year California’s ADU law changed.
6 Reasons We’re Moreno Valley’s Top ADU Company
1. Eleven Years of ADU-Only Focus
We started in 2015, the same year California rewrote its ADU laws and the permitting queue became the real product. While general contractors split their time across kitchens, bathrooms, and additions, we’ve spent eleven years on one thing: accessory dwelling units from permit to final inspection. That means we know the difference between a JADU and a detached ADU, we know when Moreno Valley’s Planning Department requires a fire sprinkler cut sheet, and we know which foundation details Riverside County Building and Safety flags every time. A designer who doesn’t build will miss the bearing point. A builder who doesn’t design will change-order you when the drawings don’t match the setback. We do both under one contract.
2. Strong Local Reputation Built on Documentation
Our reviews mention the same thing: photos of what we found, written notes, no surprises. Haven Standard Clause 4 requires evidence on every job, and that evidence goes to the homeowner, not just our files. When a homeowner in Rancho Belago asks why their soil report triggered a raised foundation, we show them the geotechnical photo and the county comment. When someone in Sunnymead Ranch wants to know why we chose a mini-split over extending the main house HVAC, we show them the load calculation. Reputation here isn’t a star rating. It’s the folder of documentation you get at the end.
3. State-Licensed, Insured, and Background-Checked
Every pro working under our name is required to hold the license and insurance California requires, and we put that license number on the page. Haven Standard Clause 3, Verified crews, means background checks, current insurance certificates, and trade-specific licensing where the county demands it. For Moreno Valley ADU work, that includes the CSLB classification for structural work, the electrical and plumbing subs pulled through our contract, and the workers’ comp coverage Riverside County verifies before they’ll issue the building permit. We don’t tell you to trust us. We show you the documentation.
4. Brand Expertise in Prefab and Modular Systems
We’re experienced with Abodu, Cover, and Dvele, the three prefab ADU brands that actually deliver in Southern California. Each system has different foundation requirements, different utility connection points, and different lead times. Abodu’s units arrive on a flatbed and crane into place, which means we need to coordinate the delivery window with Riverside County’s inspection schedule. Cover’s panelized system ships in pieces and assembles on site, which works better in Moreno Valley’s tighter lots where crane access is limited. Dvele’s smart-home integration requires electrical rough-in specifications that most general electricians haven’t seen. We’ve worked with all three, so we can tell you which one fits your lot, your budget, and your permit timeline before you sign.
5. Transparent Pricing with Written Line-Item Quotes
Haven Standard Clause 1 is flat price, written scope, written warranty, before anyone starts. When you call (951) 379-3047, we schedule a site visit to measure your lot, check setbacks against Moreno Valley’s zoning code, and identify utility locations. Then we deliver a written quote with line items: design and permit set, site work, foundation, structure, MEP rough and finish, and final inspection. If the city requests a revision, the revision is our cost, not yours. If we missed a sewer lateral location in the initial walk, we eat it. The price you sign is the price you pay. No change orders, no “while we’re in here” upsells.
6. Written Workmanship Warranty with Real Recourse
Haven Standard Clause 5 is no surprises, and that includes after we leave. Our workmanship warranty covers structural, mechanical, and finish defects for the term specified in your contract, with a clear process for claims. If a window leaks in the first winter because the flashing detail was wrong, we fix it. If the mini-split doesn’t hold temperature because the load calc was off, we correct it. The warranty is in writing, attached to your final invoice, and it names the response process. We’re not perfect. But when something’s wrong, we document what happened and we make it right.
Our Promise to You
If you’re not satisfied with any phase of work, from the initial design to the final walkthrough, we stop and fix it before moving on. Haven Standard Clause 2, Arrive on schedule, means a real window, a named lead, and a text when we’re on the way. If we miss that window without calling, the visit is free. Our pricing transparency commitment is absolute: every quote is itemized, every revision is documented, and no work starts until you’ve signed the scope and the price. We pull all permits required by Moreno Valley and Riverside County, schedule all inspections, and pass them before we request final payment. If we fail an inspection due to our work, we correct it at our cost and reschedule. That’s not a slogan. It’s Clause 5, and it’s in your contract.
Frequently Asked Questions
Most ADU projects fail at the handoff between designer and builder. We are a design-build studio, which means one contract, one price, and one party responsible for permit approval and construction. Since 2015, we’ve completed over 900 ADUs with the written price and documented record system we call the Haven Standard. Other builders may quote lower, but they often change-order once the city comments on the plans. We absorb those revisions. Call (951) 379-3047 to schedule your free estimate and compare our written scope to any other quote.
We stop and correct it before continuing. Haven Standard Clause 5 requires no surprises, and that includes quality surprises. If a finish doesn’t match the sample you approved, we reorder. If a dimension is wrong in the field, we rebuild. Your contract specifies the warranty term and the claim process, so there’s no ambiguity about what “satisfied” means. We also document every phase with photos, so there’s objective evidence of what was built. Call (951) 379-3047 for an exact quote - estimates are free.
No. Our site visit and written estimate are free. During the visit, we measure your lot, verify setbacks against Moreno Valley’s municipal code, check utility locations, and identify any conditions that would affect price or timeline. You receive a line-item written quote within five business days, with no obligation. If you choose to proceed, that quote becomes your contract scope. If you don’t, you keep the quote for comparison. Call (951) 379-3047 to schedule yours.
Yes. Every pro working under our name is required to hold the license and insurance California requires for ADU construction, including the CSLB classifications relevant to structural, electrical, and plumbing work. We put license numbers in our contracts and pull all permits through Moreno Valley’s Planning Department and Riverside County Building and Safety. We also carry general liability and workers’ compensation coverage, which the county verifies before issuing permits. Call (951) 379-3047 to verify our current status or schedule your free estimate.
We answer the phone 24 hours a day, seven days a week. Once you call (951) 379-3047, a live coordinator connects you with our local team to schedule a site visit. ADU projects are planned construction, not emergency work, so we don’t promise same-day arrival. What we do promise is a specific appointment window, a named lead who will be on site, and a text when they’re on the way. Most Moreno Valley homeowners get their site visit within one to two weeks of calling, depending on seasonal demand. The estimate follows within five business days. For your timeline and availability, call (951) 379-3047 - estimates are free.
