Contact Ellery ADU Studio Riverside - Free ADU Estimate in Riverside
Call (951) 418-2910 to schedule your free ADU estimate in Riverside. There’s no hard sell when you reach us, just a live coordinator who’ll find a time that works. We offer same-day assessment availability most weekdays, and every estimate includes a written, line-item quote before any work begins.
What Happens When You Call
We answer and listen. A live coordinator picks up during our operating hours, takes your address in Riverside or nearby, and asks what you’re considering - a backyard cottage, garage conversion, or detached unit. We’ll tell you honestly whether your lot looks feasible from what you describe, and we’ll schedule an on-site assessment at no charge.
We assess on your property. Our estimator arrives in the scheduled window, measures your space, checks setback lines, and notes utility access. In Riverside, we regularly see older lots in neighborhoods like Wood Streets with non-conforming setbacks that need careful review, and newer parcels in Orangecrest where utility tie-ins are straightforward. We photograph what we find and record site conditions.
You receive a written estimate. Within two business days, you get a line-item quote: design fees, permit set, construction, and any site-specific conditions we identified. This is Clause 1 of The Haven Standard - flat price, written scope, written warranty, before anyone starts. The price does not change unless you change the scope.
We build to the drawings. Once you approve, we produce the permit set, pull Riverside permits, and schedule construction with verified crews. You receive photo documentation at key milestones, and we pass all inspections before final payment.
Why Riverside Homeowners Call Us First
- We know Riverside’s permitting rhythm. We’ve worked with Riverside Building & Safety long enough to understand their ADU checklist and typical review timeline. That means fewer surprises and no redesign loops that eat your budget.
- Every pro on your job is required to hold the license and insurance California requires. We verify coverage before anyone steps on your property, and license numbers are documented in your project file. You can check status yourself.
- Our pricing is flat and fixed. The written estimate you approve is the price you pay. No “while we’re in here” additions, no material markup surprises. If we missed something in our assessment, that’s our cost, not yours - Haven Standard Clause 5.
- We guarantee our workmanship in writing. Every ADU we build carries a documented warranty with specific coverage terms, not a handshake promise. You’ll know exactly what’s covered and for how long before construction starts.
Our Service Area Around Riverside
We serve Riverside directly and reach most surrounding communities within 30 to 45 minutes during normal traffic. That includes Rubidoux, Pedley, El Sobrante, Sunnyslope, Glen Avon, and Mira Loma to the west; Norco and El Cerrito to the north; Eastvale and Corona to the east; and Rialto to the northwest. If you’re near these areas but don’t see your neighborhood listed, call anyway - we regularly assess properties on the edges of our mapped zone and will tell you honestly whether your location works for our crew routing.
Frequently Asked Questions - Booking & Estimates
Yes, the on-site assessment and written estimate are completely free with no obligation to hire us. We believe you can’t make a six-figure decision without a real number in hand, so we don’t charge for the work of producing one. Call (951) 418-2910 to schedule yours.
We typically have assessment availability within one to three business days for most Riverside addresses. Same-day slots open up occasionally when a project finishes early or a reschedule occurs. We’ll offer you the earliest window that fits your schedule when you call.
No, we do not add surcharges for assessments scheduled during our standard operating hours, which run 7:00 AM to 7:30 PM every day including weekends. Evening assessments are available within those hours. We don’t offer after-hours or overnight appointments.
Your property address and a rough idea of what you want - square footage, detached or attached, budget range if you have one. If you’ve already checked your city’s ADU zoning webpage or have a survey, that’s helpful but not required. We’ll guide you through what’s relevant.
We accept check, ACH transfer, and major credit cards. Payment is structured in milestones tied to permit approval, construction start, and final inspection - never 100% upfront. Your written estimate includes the exact payment schedule. Call (951) 418-2910 for details.
