Contact Ellery ADU Studio Anaheim - Free ADU Estimate in Anaheim
Call (657) 366-5740 to schedule your free ADU estimate in Anaheim. When you reach us, you’ll speak with a live coordinator who connects you with our local team. There’s no hard sell, no deposit required to get your assessment, and we often have same-week availability for site visits across Anaheim and the surrounding cities.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during business hours, takes down your address in Anaheim, and asks what you’re hoping to build - a garage conversion, a backyard cottage, an attached addition, or something else. We don’t run you through a script. We need ten minutes to understand your property and your timeline.
Step 2: We schedule your site assessment. Within a few days, we send a local ADU specialist to walk your property in Anaheim. They’ll measure setbacks, check utility access, note any oak trees or slope issues that affect placement, and photograph what exists now. You get a copy of those photos and notes by email within 24 hours.
Step 3: You receive a written estimate. Our estimate is a line-item document, not a verbal ballpark. It breaks out design, permit expediting, foundation, framing, mechanical, and finish work separately. Per Haven Standard Clause 1, the price is flat before anyone starts. If Anaheim’s planning department requests plan corrections, that labor is on us, not you.
Step 4: We build to the drawings. Once you approve the permit set and the contract, we file with Anaheim’s Community Development Department, schedule inspections, and execute the build. Every phase is photographed and logged. You receive that documentation at final walkthrough.
Why Anaheim Homeowners Call Us First

- We know Anaheim’s permitting rhythm. We’ve filed ADU plans through Anaheim’s Community Development Department enough times to know which plan checkers flag roof-height calculations and which ones focus on utility separation. That local knowledge shaves weeks off your permit timeline.
- Every pro on your job meets state requirements. Every contractor working under our name is required to hold the license and insurance California requires, and we keep those documents on file. We don’t send untested crews to a six-figure ADU build.
- The price on the page is the price you pay. Haven Standard Clause 5: no surprises. No “while we’re in here” upsells, no change orders because we “found something unexpected” that a competent site assessment should have caught. If we miss it in assessment, we eat it.
- We warranty what we build. Our workmanship guarantee covers structural, mechanical, and waterproofing work for a period spelled out in your contract. We don’t hide the terms in fine print. You’ll read them before you sign.

Frequently Asked Questions - Booking & Estimates

Yes. The site assessment and written estimate cost nothing and obligate you to nothing. We believe you shouldn’t pay to find out whether an ADU works on your property. Call (657) 366-5740 to schedule yours.
We typically schedule site assessments within three to five business days for Anaheim addresses. During slower permit seasons - late fall through winter - we sometimes have next-day openings. We’ll offer you the first slot that matches your availability. Call (657) 366-5740 to check this week’s calendar.
No. Our site assessment fee structure doesn’t change based on when we meet. Our operating hours extend into evening on weekdays and include Saturday and Sunday, so we can accommodate homeowners who work standard hours. The estimate remains free regardless of appointment time.
Your property address, a rough idea of your budget range, and any thoughts on size or placement. If you have a recent survey or property plot, that’s helpful but not required. We pull permit history and zoning data ourselves. The ten-minute call is mostly us listening to what you need.
We accept check, ACH transfer, and major credit cards. Payment is structured around construction milestones - design approval, permit issuance, rough inspection, final walkthrough - not demanded upfront. The schedule is spelled out in your written contract per Haven Standard Clause 1. Call (657) 366-5740 to discuss what structure works for your project.
