Contact Ellery ADU Studio San Bernardino - Free ADU Estimate in San Bernardino
Call (909) 359-6463 to schedule your free ADU estimate in San Bernardino. When you reach us, you’ll speak with a live coordinator who connects you with our local team - no hard sell, no pressure, just a straightforward conversation about your property and what an accessory dwelling unit could look like. We offer same-day availability for initial assessments across San Bernardino and the surrounding valleys.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during business hours, takes your address in San Bernardino, and asks what you’re hoping to build - a backyard cottage for aging parents, a rental unit to offset your mortgage, or a home office that qualifies as a full dwelling. You’ll get a sense right away whether your lot fits the typical profile, and we’ll flag any obvious zoning constraints before we drive out.
Step 2: We schedule a site assessment. We visit your property within 48 hours, usually sooner. Nadia Ellery or a senior member of our local team walks the lot with you, checks setback lines, notes utility locations, and photographs existing conditions. We measure what we can see, and we mark what we’ll need to verify with the city - San Bernardino’s ADU ordinance has specific rules about parking replacement and fire separation that vary block by block.
Step 3: You receive a written estimate. Within three business days, you get a flat-price proposal with line-item costs for design, permitting, and construction. This is Haven Standard Clause 1: Have it in writing. The price includes the permit set, the build, and the finish work - one contract, one number, no change orders unless you change the scope. We also include a realistic timeline based on San Bernardino’s current planning department queue.
Step 4: We build what we quoted. Once you sign, we produce the architectural drawings, submit for permit, and schedule construction. Every phase is documented with photos and inspection records. Haven Standard Clause 4: Evidence on every job. When we finish, you have a permitted, inspected ADU and a file that proves it.
Why San Bernardino Homeowners Call Us First

- We know San Bernardino’s permitting rhythm. We’ve worked with San Bernardino’s planning and building departments since opening our local branch, and we understand how their ADU checklist differs from neighboring cities. That familiarity saves weeks on the back end.
- Every pro on your job is required to hold the license and insurance California requires. We verify coverage before anyone sets foot on your property, and license numbers are included in your project documentation. You can cross-check every trade.
- Transparent pricing with no hidden fees. Your written estimate lists every cost - design, permit fees, materials, labor, finish - and Haven Standard Clause 5 locks it: no surprises, no “while we’re in here” upsells. The price you sign is the price you pay.
- Workmanship backed by a written warranty. Every ADU we build carries a documented warranty on construction defects, with clear terms on what’s covered and for how long. You get the paper before we start, not after something goes wrong.
