Contact Ellery ADU Studio Hesperia - Free ADU Estimate in Hesperia
Call us at (760) 493-7752 to schedule your free ADU estimate in Hesperia. When you reach us, a live coordinator will connect you with our local team. There’s no hard sell, no deposit required to get your number, and we can usually assess your property within a few business days. We’ll walk your lot, check setback and utility access, and email you a written line-item estimate you can actually use to compare.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during business hours and connects you with our Hesperia team. We’ll ask about your lot size, existing utility connections, and whether you’re thinking detached, attached, or garage conversion. This takes five minutes and costs nothing.
Step 2: We schedule a site assessment. We visit your property in Hesperia or a nearby community, measure actual setbacks, photograph utility locations, and note any oak tree protection zones or slope issues that San Bernardino County will flag later. You get a copy of our field notes.
Step 3: You receive a written estimate. Within two business days, we email a fixed-price proposal with every line item separated: design, permit set, site prep, foundation, utility tie-in, finish work. Clause 1 of our Haven Standard requires this in writing before anyone starts. The price does not change unless you change the scope.
Step 4: We permit, build, and document. Once you approve, we produce the architectural drawings, submit to San Bernardino County, and keep you updated at each inspection milestone. Every phase gets photo documentation under Clause 4. You get the keys to a finished ADU with a written workmanship warranty and a complete project file.
Why Hesperia Homeowners Call Us First
- We know Hesperia’s permitting reality. San Bernardino County’s ADU queue moves differently than L.A. County’s, and we’ve learned which plans examiners want structural calcs upfront versus which ones flag fire sprinkler calculations on converted garages. That local knowledge saves weeks.
- 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 appear on every contract. You’re not guessing who’s actually swinging the hammer.
- Our pricing is flat and fixed. Clause 1 of the Haven Standard means you get a written, line-item price before we pull the first permit. No “while we’re in here” discoveries, no change orders for standard conditions we should have seen. If we miss something in our assessment, we absorb it.
- We warranty what we build. Every ADU leaves with a written workmanship guarantee and a complete photo record of what we found and what we did. If something we installed fails because of how we installed it, we fix it. That’s Clause 5: no surprises after the fact.
Our Service Area Around Hesperia
We design, permit, and build ADUs throughout the High Desert and Mountain Communities. Typical response times: Hesperia same week; Oak Hills and Phelan within 3-4 days; Spring Valley Lake and Piñon Hills within a week; Crestline, Lake Arrowhead, Running Springs, and Wrightwood within 7-10 days depending on mountain weather; Muscoy, San Bernardino, and Rialto within 3-5 days. If you’re near these areas but not listed, call anyway. We’ve assessed lots in Lucerne Valley, Apple Valley, and the Cajon Pass that weren’t technically in our posted radius, and we don’t turn away reasonable drives without checking first.
Frequently Asked Questions - Booking & Estimates
Yes. The site assessment and written estimate cost nothing and obligate you to nothing. We treat it as a real working meeting: we measure, photograph, check county GIS for your parcel’s constraints, and produce a line-item proposal you could take to any other builder for comparison. Call (760) 493-7752 to schedule yours.
We can usually assess a Hesperia property within 3-5 business days of your call, sometimes sooner depending on our current permit submission calendar. We do not book assessments on Saturdays. Call (760) 493-7752 and we’ll find a time that works.
No. We do not schedule site assessments or construction work on Saturdays, and we do not offer after-hours appointments. Our hours are Monday through Friday, 7:00 AM to 7:00 PM, and Sunday 7:00 AM to 7:00 PM. Everything is priced the same regardless of which day we meet.
Your address, a rough idea of your lot dimensions, and whether you’re considering a detached unit, attached addition, or garage conversion. If you have a recent survey or property plot, that’s helpful but not required. We’ll pull county records ourselves. The call takes five minutes. Call (760) 493-7752 when you’re ready.
We accept check, wire transfer, and major credit cards. Large ADU projects are typically milestone-based: deposit at contract, progress payments at framing and rough inspection, final payment at certificate of occupancy. We’ll detail the exact schedule in your written estimate so there’s no ambiguity. Call (760) 493-7752 to discuss your project and receive a payment schedule with your proposal.
