Contact Ellery ADU Studio Irvine - Free ADU Estimate in Irvine
Call (657) 233-9738 to schedule your free ADU estimate in Irvine. 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 numbers, and we can usually assess your property within a few days of your call. We’ll walk your lot, check your setbacks against the current Irvine code, and leave you with a written estimate you can actually use.
What Happens When You Call
Step 1: We answer and listen. Our coordinator picks up, takes your address in Irvine, and asks what you’re trying to solve. Rental income, aging parents, home office, or future resale - we need to know the goal before we size the unit. You’ll get a sense of whether we’re a fit in about five minutes, not fifty.
Step 2: We schedule a site assessment. We visit your property in Irvine, measure the buildable footprint, photograph the access route for materials, and flag anything that could affect the permit path. In older neighborhoods like University Park or the ranch-style pockets near Turtle Rock, we’ve learned to check for overhead power lines and tight side yards that standard surveys miss.
Step 3: You receive a written estimate. Within 48 hours of our visit, we send a line-item quote: design fees, permit costs, construction scope, and a fixed total. This is Clause 1 of The Haven Standard - flat price, written scope, written warranty, before anyone starts. If Irvine’s planning department requests plan revisions, we absorb that cost. The price you sign is the price you pay.
Step 4: We build to the drawings. Once permitted, your project moves into our build queue. A named project manager runs your job, sends photo evidence at each phase, and closes out only after final inspection passes and you’ve signed off on the punch list. Every ADU we’ve completed in Irvine since opening this branch leaves a documented record.
Why Irvine Homeowners Call Us First

- We know the local permit landscape. Irvine’s ADU process runs through two different departments depending on whether your lot is in the older “village” neighborhoods or newer developments like Great Park. We’ve navigated both enough times to know which planner handles which zone, and we build that knowledge into your timeline from day one.
- Every pro on your job carries required coverage. The tradespeople working under our name in Irvine are required to hold the license and insurance California requires for their scope. We verify it before they step on your property, and their license numbers sit in your project file.
- Our pricing is fixed and fully disclosed. The estimate you receive lists every major line item: design, structural, MEP, finishes, permit fees, and our project management. If we missed something, that’s our cost, not yours. No change orders unless you add scope yourself.
- We warranty what we build. Our workmanship guarantee covers structural and weather-sealing defects for the period specified in your contract. We spell out the exact terms in writing before construction starts, not in a handshake after.
Our Service Area Around Irvine
We live and work in Orange County, and most of our assessments happen within 30 minutes of our Irvine office. That includes Tustin, Lake Forest, Santa Ana, Mission Viejo, Costa Mesa, Newport Beach, Orange, Laguna Beach, Anaheim, Garden Grove, and Huntington Beach. If you’re outside these cities but still in coastal Orange County, call us anyway. We’ve taken on ADU projects as far south as San Clementa and as far north as Yorba Linda when the site and the timeline made sense.
Frequently Asked Questions - Booking & Estimates

Yes. Our initial site assessment and written estimate cost nothing and obligate you to nothing. We believe you can’t make a six-figure decision without real numbers in hand, and we won’t charge you to produce them. Call (657) 233-9738 to schedule yours.
We typically schedule assessments within three to five business days of your call, depending on current project load. During slower permitting seasons, we’ve been out next day. We’ll give you an honest window when you call, not a promise we can’t keep.
No. Our assessment fee structure doesn’t change based on when we visit. We know many Irvine homeowners work standard hours and need flexibility. We’ll find a time that works, and the estimate itself remains free regardless.
Your property address, a rough idea of your budget range, and your goal for the ADU. If you have a recent survey or the original house plans, that’s helpful but not required. We’ll pull the parcel data and zoning ourselves before we arrive. The less homework you do, the more questions we’ll ask - either way works.
We accept bank transfer, check, and major credit cards. For construction draws, we schedule payments tied to permit milestones and inspection passes, not arbitrary calendar dates. The payment schedule appears in your written contract, so you know exactly when each draw is due and what work it covers.
