ADU Specials in San Bernardino, CA
We’re running these offers because San Bernardino homeowners deserve to know what an ADU project costs before anyone sets foot on the property. Call (909) 359-6463 and we’ll put a written number in your hand, not a ballpark that drifts upward later. Every special below pairs with our standard guarantees: written price first, photo record on every visit, and the 365-Day Done Right Promise.
Current Offers
Free Second Opinion on Any Written ADU Estimate
Already have a quote from another design-build firm or prefab coordinator? Bring it to us. We’ll review the scope line by line, check for missing permit fees or utility tie-in costs that tend to surface mid-project, and tell you where the numbers land relative to what we’ve seen on 900-plus ADUs since 2015. No obligation to hire us. Valid through December 31, 2026. Mention this offer when you call (909) 359-6463.
Written Price Guarantee Locked at Consultation
Every project we take gets a written price before work starts, per Haven Standard Clause 1. This offer highlights what already happens: you sit down with us, we measure your site, identify your zoning envelope, and leave with a fixed-scope quote. In San Bernardino’s R-1 zones, that means we account for your front-yard setback, any alley access for utility trenching, and whether your existing garage slab can carry conversion loads. Valid through December 31, 2026. Mention this offer when you call (909) 359-6463.
Documented Photo Record Included on Every Visit
Most builders hand you a checklist at the end. We hand you timestamped photos: what your foundation looked like before trenching, where the sewer lateral sits relative to your proposed unit, how the electrical panel was configured before and after the subpanel install. In the Muscoy and Verdemont areas, we’ve found this matters especially for hillside sites where drainage documentation protects you later. Valid through December 31, 2026. Mention this offer when you call (909) 359-6463.
365-Day Done Right Promise Activation
This isn’t an extended warranty you pay extra for. It’s a written guarantee, activated at project closeout, that says if the finished ADU doesn’t match the permitted drawings, we make it right. We’ve honored this on framing corrections in Del Rosa, on window placement in Arrowhead, and on a roof pitch mismatch near Perris Hill that nobody caught until final walkthrough. Valid through December 31, 2026. Mention this offer when you call (909) 359-6463.
Prefab & Modular Specification Review at No Charge
Looking at Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or James Hardie systems? We’ll coordinate directly with the manufacturer, review their foundation and utility specs against your San Bernardino site conditions, and flag any gaps before you sign their contract. We do this under our single design-build agreement so there’s no finger-pointing if the module dimensions don’t match the pad we pour. Valid through December 31, 2026. Mention this offer when you call (909) 359-6463.
Live Person Answer, 24/7 - No Voicemail Queue
This isn’t a discount. It’s a promise that when you call (909) 359-6463, a human picks up, any hour, any day. We’ve kept this running since 2015 because ADU questions don’t wait for business hours. A neighbor in Highland called at 10 PM worried about a permit correction notice; we had the answer by morning because the call got logged that night. Valid through December 31, 2026. Mention this offer when you call (909) 359-6463.
How to Redeem
Step 1: Call (909) 359-6463 and mention the offer by name. The person who answers will log it to your file before you hang up.
Step 2: Book your site visit or estimate review. For the Free Second Opinion, email your existing estimate ahead so we can prep. For new projects, we’ll schedule a walkthrough of your San Bernardino property.
Step 3: Present nothing at time of service. We already noted it when you called. Your written quote or project folder will reference the offer automatically. No coupons to clip, no codes to forget.
What These Offers Don’t Cover
We don’t discount the work itself and then recover it with change orders. Haven Standard Clause 1 forbids that. We don’t offer “limited time” pressure that expires Friday. The December 31, 2026 date is a real calendar boundary, not theatre. And we don’t stack these offers against each other; pick the one that fits your situation and we’ll apply it.
If you’re comparing us to another ADU builder in San Bernardino, ask them three things: Is your price written before work starts? Will I see photos of what you found, or a summary of how it felt? And if the finished unit doesn’t match the drawings, who fixes it? Their answers will tell you plenty.
Call (909) 359-6463 to schedule your free estimate or second opinion. Estimates are free, written, and fixed-scope.
