ADU Specials in Hesperia, CA
We’re running these offers because Hesperia homeowners deserve honest value on ADU work, not gimmicks. Call (760) 493-7752 to ask about any special below, and we’ll tell you exactly what it covers and what it doesn’t.

Current Offers
Free Second Opinion on Any Written ADU Estimate
Already have a quote for a garage conversion, detached ADU, or JADU in Hesperia? Bring it to us. We’ll review the scope, the line items, and the permit strategy, then tell you where it’s solid and where it might be missing something. No obligation to hire us.
Valid through December 31, 2026. Mention this offer when you call (760) 493-7752.
365-Day Done Right Promise - Locked In Writing at Signing
This isn’t a discount. It’s a guarantee that protects your investment after the last invoice. If your finished ADU in Hesperia isn’t built to the permitted drawings, we make it right. Under Haven Standard Clause 5, the scope is locked at signing; no door-side upsells, no scope creep, no surprises.
Valid through December 31, 2026. Mention this offer when you call (760) 493-7752.
Documented Photo Record Included on Every Visit - No Extra Charge
Every Ellery ADU Studio project in Hesperia includes photographic evidence of what we found and what we did, not a summary of how it felt. You’ll see the existing slab thickness, the utility trench depth, the framing inspection pass - documented, dated, and delivered. Other studios charge for this or skip it entirely. We consider it standard.
Valid through December 31, 2026. Mention this offer when you call (760) 493-7752.
Written Price Before Any Work Starts - Haven Standard Clause 1
We don’t do “call for a quote.” On every Hesperia ADU project - garage conversion, new detached unit, JADU, or full site prep with utilities - you’ll receive a written, line-item price before any work begins. The price locks at contract. If we missed something in our site walk, that’s our cost, not yours.
Valid through December 31, 2026. Mention this offer when you call (760) 493-7752.
Live Person Answers Your Call 24/7 - No Voicemail Queue
Questions about your permit status at 9 PM? Concerned about a site condition on Sunday? A real person answers Ellery ADU Studio’s Hesperia line around the clock. No callback promise that doesn’t materialize. No automated maze. This matters most when your project is active and you need a straight answer fast.
Valid through December 31, 2026. Mention this offer when you call (760) 493-7752.
One-Contract Design-Build - Designer and Builder Under One Roof
Most Hesperia ADU projects split design and construction into separate contracts. When something doesn’t match the drawings, each side points at the other. Our single-contract model covers ADU Design & Permitting, construction, and site prep under one written price. One call. One accountable party. No coordination gaps between your architect and your contractor.

How to Redeem
Step 1: Call and mention the offer. Dial (760) 493-7752 and name which special you’re asking about. We’ll confirm it applies to your Hesperia project type.
Step 2: Book your site visit. We’ll schedule a walk of your property - typically within a few business days - to assess existing conditions, setbacks, and utility access. You’ll receive a written price after, never before we understand the scope.
Step 3: Present at contract signing. The offer terms are noted on your written agreement. No verbal promises, no memory games. What we said on the phone appears in the contract you sign.
What These Offers Don’t Cover
We don’t stack discounts or play pricing games. The Haven Standard runs on transparency, not urgency theatre. These aren’t “limited to the first ten callers” or “expires Friday at midnight” promotions. They’re standing commitments we make to every Hesperia homeowner who works with Ellery ADU Studio, published here so you can verify them before you call.
We also don’t quote specific project costs without seeing your site. A garage conversion in Spring Valley Lake faces different soil conditions than one in Oak Hills. A detached ADU near the Hesperia airport corridor may need acoustic mitigation that doesn’t apply near Main Street. The written price we provide after site visit accounts for your actual conditions, not a generic template.
Why Hesperia Homeowners Choose Ellery ADU Studio
Since 2015, we’ve designed, permitted, and built over 900 ADUs across California. In Hesperia specifically, we’ve navigated San Bernardino County’s fire hazard severity zones, worked with the local water district on meter splits, and coordinated with Southern California Edison on service upgrades for detached units. We know where the county requires engineered retaining walls for sloped lots and where a standard foundation suffices.
Our prefab and modular fluency spans Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie systems. If you’re considering a factory-built ADU for your Hesperia property, we specify and coordinate delivery, crane set, and finish-out under the same single contract as our stick-built projects. The written price covers the full scope, not just the module.
Background-checked, uniformed crews handle every phase. Our license number appears on every page of this site, verified, not just claimed. And Nadia Ellery remains directly involved in project review - because an owner-operated studio doesn’t have layers of management between the person who priced your job and the person accountable for delivering it.
Frequently Asked Questions
Every offer listed here is standard on every Ellery ADU Studio project - the 365-Day Done Right Promise, the documented photo record, the written price guarantee, and live phone answering all apply together. There are no separate “stackable” discounts beneath these. Call (760) 493-7752 and we’ll confirm exactly what’s included in your written quote.
We don’t price-match. We provide a Free Second Opinion on any written estimate you already have, and we’ll explain where their scope and ours differ. Often the lower number omits permit fees, utility trenching, or final inspection corrections. Under Haven Standard Clause 1, our written price includes everything required to deliver a permitted, inspected, finished ADU.
Haven Standard Clause 5 locks the scope at signing. The only price changes occur if you request a change order in writing - a larger window, upgraded flooring, an added mini-split zone. We don’t discover “unforeseen conditions” that suddenly cost more. If we missed something in our site walk, we absorb it. That’s the agreement we make before any work starts.
No. Permit timelines depend on San Bernardino County’s review queue, which we don’t control. The promise covers construction quality: if the finished ADU doesn’t match the permitted drawings, we make it right. We’ve seen Hesperia permits move in eight weeks and we’ve seen them take sixteen. We keep you updated weekly, but we don’t guarantee county speed.
Date-stamped images of existing conditions before work begins, progress shots at rough electrical and plumbing, pre-inspection verification photos, and final walkthrough documentation. You receive these in a shared digital folder, not a printed album that gathers dust. If a future buyer or appraiser asks about your ADU’s construction quality, you have evidence, not anecdotes.
Yes. Our single-contract design-build model covers site-built and factory-built ADUs equally. The written price, photo documentation, 365-Day Done Right Promise, and live phone support all apply whether we’re framing walls on your lot or coordinating a Dvele module delivery to your Hesperia property.
