Contact Ellery ADU Studio Rialto - Free ADU Estimate in Rialto
Call us at (951) 476-1467 to schedule your free ADU estimate in Rialto. When you reach us, you’ll talk to a live coordinator who’ll connect you with our local team - no hard sell, no deposit required, just a real conversation about your property and what an ADU could look like. We typically have assessment slots available within a few business days, and we’ll work around your schedule, not ours.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during our operating hours, takes down your address in Rialto, and asks what you’re hoping to build - a detached unit for rental income, a granny flat for family, or something else entirely. There’s no script to read from; we want to understand your actual situation before we say anything about price.
Step 2: We schedule a site assessment. We visit your property in Rialto, measure the buildable area, check setbacks against current San Bernardino County code, and photograph existing conditions. The assessor brings a checklist drawn from 900-plus ADU projects since 2015, so nothing obvious gets missed.
Step 3: You receive a written estimate. Within two business days, you get a line-item proposal: design fees, permit expediting, construction costs, and a fixed total. This is Haven Standard Clause 1 - “Have it in writing” - and it means the price won’t shift unless you change the scope.
Step 4: We build to the drawings we agreed on. Once you sign, our team handles permit submission, construction, and final inspection. You receive photo documentation at key milestones, and we don’t request final payment until the work passes inspection and matches the plans.
Why Rialto Homeowners Call Us First
- We know Rialto’s permitting reality. San Bernardino County’s ADU queue moves differently than Riverside County’s, and Rialto’s specific zoning overlay has its own quirks. We’ve navigated it enough times to know which plans get kicked back and how to avoid that delay.
- Every pro on your job carries required coverage. The crews working under our name are required to hold the license and insurance California requires for ADU construction. We verify it before they step on your property, and their license numbers go in your project file.
- The price on the page is the price you pay. Haven Standard Clause 5 - “No surprises” - means no hidden permit fees, no “while we’re in here” upsells, and no change orders unless you request them. We itemize everything upfront so you can compare apples to apples.
- We document what we actually found. Haven Standard Clause 4 - “Evidence on every job” - means dated photos and written notes of existing conditions before we start. If a soil issue or utility conflict appears, we show you the photo, explain the options, and agree on a path before any extra work happens.
Before
AfterOur Service Area Around Rialto
We build ADUs throughout the Inland Empire, with our closest response times to properties in Rialto, Fontana, and San Bernardino - usually within 30 minutes for assessments. Rancho Cucamonga, Ontario, and Montclair follow closely. We regularly travel to Riverside, Redlands, Eastvale, Upland, Moreno Valley, and Chino for full projects. If you’re near these cities but not inside them - Bloomington, Grand Terrace, Muscoy, or the unincorporated pockets between - call us anyway. We’ve pulled permits in most of San Bernardino and western Riverside counties, and we’ll tell you honestly if your location is outside our current range.
Frequently Asked Questions - Booking & Estimates
Yes. The site assessment and written estimate cost nothing, and you’re not obligated to move forward. We believe you can’t make a six-figure decision without a real number in hand, so we put one there. Call (951) 476-1467 to schedule yours.
We typically schedule assessments within three to five business days of your call, sometimes sooner depending on current project load. We don’t promise same-day visits because a rushed assessment misses things that cost you later. Call (951) 476-1467 to check this week’s availability.
No. Our assessment fee structure doesn’t change based on when we meet. Our operating hours are Monday through Friday 7:00 AM to 7:00 PM, and Sunday 7:00 AM to 7:00 PM. Saturday we’re closed. We’ll find a time that works without surcharging you for it.
Your property address, a rough idea of the unit size you’re considering, and whether you’ve checked basic setback rules with the city. If you have a survey or plot plan, that’s helpful but not required. The coordinator will ask what matters and skip what doesn’t. Call (951) 476-1467 when you’re ready.
We accept check, ACH transfer, and major credit cards. Payment is structured in milestones tied to permit approval and construction phases - never a large upfront deposit before work begins. The exact schedule appears in your written estimate under Haven Standard Clause 1.
