ADU Specials in Irvine, CA
We’re running these offers because Irvine homeowners shouldn’t have to guess what an ADU project costs before they commit. Call (657) 233-9738 and we’ll put a written price in your hand, not a ballpark. Every special below pairs with our standing Haven Standard guarantees: written price before work starts, documented photo record on every visit, and our 365-Day Done Right Promise backed in writing.
Current Offers
Free Second Opinion on Any Written ADU Estimate
Already have a quote for a garage conversion, detached ADU, or JADU from another Irvine design-build firm? We’ll review the scope, the line items, and the permit strategy, then tell you where the numbers land and whether anything’s missing. No obligation, no pressure to switch. We’ve caught $12,000 foundation omissions and redundant utility trenching on estimates from outfits that don’t build in Irvine regularly.
Valid through December 31, 2026. Mention this offer when you call (657) 233-9738.
Written Price Guarantee with Every Consultation
Most Irvine ADU companies hand you a “rough range” and sharpen the pencil later. Under Haven Standard Clause 1, we put the full project price in writing before any work starts, every time. This isn’t a discount, it’s a structural protection: your garage conversion or new detached ADU quote locks at signing, with no door-side upsells and no scope creep. Under Clause 5 (No Surprises), what you sign is what you pay.

365-Day Done Right Promise - Documented in Your Contract
If your finished ADU in Irvine isn’t built to the permitted drawings, we make it right. Not a verbal assurance, a written clause in every contract. This covers setback compliance, ceiling heights, egress window placement, and utility connections exactly as approved by the City of Irvine. We’ve honored this on framing corrections in Woodbridge and waterproofing adjustments in Northwood, no dispute required.
Valid through December 31, 2026. Mention this offer when you call (657) 233-9738.
Documented Photo Record Included on Every Visit
Every Ellery crew documents what they find and what they do, not a summary of how it felt. You receive dated photos of existing conditions, mid-construction milestones, and final finishes. In University Park, this helped a client verify that their original garage slab was 4 inches and suitable for conversion, saving a $3,800 unnecessary foundation line item another firm had proposed. The photo record is standard, not an upsell.

Live Person Answers Calls 24/7 - No Voicemail Queue
Call (657) 233-9738 at 10 PM on a Tuesday or 6 AM on Sunday. A real person picks up, takes your information, and schedules your consultation. No callback promise that doesn’t materialize, no automated system routing you through six options. This matters when you’re comparing estimates and need a quick clarification on your Irvine ADU’s Fire Access Requirement or your property’s specific zoning overlay.

Single-Contract Design-Build with Prefab & Modular Coordination
Ellery specifies and coordinates prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie under one contract at one written price. No designer blaming the builder, no builder blaming the designer. Your Irvine ADU project moves from permitted drawings through final inspection with one accountable party. We’ve placed Cover units in Quail Hill and Abodu systems in Orchard Hills, always within the same fixed-price structure.

How to Redeem

Step 1: Call (657) 233-9738 and mention the offer you want to use. A live person will answer, confirm availability, and pencil you in.
Step 2: We’ll book your site visit or consultation. For garage conversions and detached ADUs in Irvine, we typically walk the property, measure setbacks against the City of Irvine’s zoning map, and identify any utility routing challenges on the spot.
Step 3: Present any competing written estimate at your consultation if you’re using the Free Second Opinion. All other offers apply automatically, no coupon code needed, just the mention when you call.
Every special runs through December 31, 2026, and stacks with our standing Haven Standard guarantees. No artificial caps, no “first 10 callers” theatre. We’re independently owned and operated in Irvine, and we’ve found that clear terms build better projects than pressure tactics.
Frequently Asked Questions
Yes. The Free Second Opinion, Written Price Guarantee, 365-Day Done Right Promise, and Documented Photo Record all apply to every Ellery project by default. Call (657) 233-9738 and we’ll confirm which elements fit your specific garage conversion or new detached ADU in Irvine.
Yes. Junior ADUs and interior conversions in Irvine fall under the same Haven Standard structure, with written pricing before work starts and the 365-Day Done Right Promise in writing. The Free Second Opinion also covers estimates you’ve received for JADU projects.
That offer requires a written estimate already in hand from another firm. If you don’t have one, we’ll start with a fresh consultation and Written Price Guarantee under Haven Standard Clause 1. Call (657) 233-9738 to schedule, either way.
No. City of Irvine permit timelines vary by project type and current plan-check volume. The promise covers construction quality and adherence to approved drawings, not municipal processing speed. We do pull all required permits and pass all inspections as part of our standard scope.
Under Haven Standard Clause 5 (No Surprises), the scope locks at signing. If we encounter unforeseen conditions, like a buried oil tank or non-compliant septic, we document with photos, explain the finding, and quote any additional work in writing before proceeding. No door-side upsells. Call (657) 233-9738 for an exact quote, estimates are free.
