Contact Ellery ADU Studio Camarillo - Free ADU Estimate in Camarillo
Call us at (805) 301-9518 to schedule your free ADU estimate in Camarillo. We’re here Monday through Friday from 7 AM to 8 PM, Saturday and Sunday from 8 AM to 8 PM. When you call, you’ll reach a live coordinator who’ll connect you with our local team - no hard sell, no deposit required to get on the schedule. Most Camarillo homeowners who call this week can expect an assessment within a few days, and your written estimate follows within 48 hours of our visit.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during business hours, takes your address in Camarillo, and asks what you’re trying to solve - a rental unit for income, space for family, or a home office that doesn’t require a commute to Thousand Oaks or Westlake Village. We don’t run a script; we take notes.
Step 2: We schedule your site assessment. We find a window that works, confirm it with a text, and send a named designer-build lead who knows Camarillo’s zoning. You’ll get a reminder the day before and another text when they’re en route. Haven Standard Clause 2: a real window, a named person, a text when they’re on the way.
Step 3: You receive a written line-item estimate. Within 48 hours of the visit, you get a flat price for design, permitting, and construction - one contract, one number. No allowance categories that balloon later. No “TBD” on the electrical panel upgrade. Clause 1 of the Haven Standard: have it in writing before anyone starts.
Step 4: We build to the drawings we permitted. The same team that measured your backyard handles the permit set and coordinates the build. When we finish, you get photo documentation, inspection sign-offs, and a workmanship warranty in writing. Clause 4: evidence on every job.
Why Camarillo Homeowners Call Us First

- We know the local timeline. Camarillo’s Planning Division processes ADU permits on a predictable rhythm we’ve tracked since this branch opened. We know when the queue slows in late summer and how to front-load drawings so your permit doesn’t sit. That local knowledge saves most Camarillo clients 3-6 weeks compared to designers who file from out of county.
- Every pro on your job meets California’s licensing and insurance requirements. We don’t send day laborers or unlicensed handymen to pull wire or pour your foundation. Every crew member’s license number and insurance certificate is documented in your project file before they step on your property. Clause 3 of the Haven Standard: verified crews, license numbers on the page.
- The price we write is the price you pay. Our estimates are flat-fee, line-item, and fixed. If we missed a soil condition at your Camarillo property, that’s our cost to absorb. We don’t charge for “unforeseen” trenching or a panel upgrade we should have spotted. Clause 5: no surprises, no door upsell, no scope creep.
- We warranty the work in writing. Every ADU we build in Camarillo carries a documented workmanship guarantee with specific coverage terms, not a handshake and a phone number that goes to voicemail. You get the paper copy at final walkthrough, and it lives in your project portal alongside every photo we took.

Frequently Asked Questions - Booking & Estimates

Yes. The site assessment and written estimate cost nothing, and you’re not obligated to move forward. We believe you can’t make a six-figure decision without a real number in your hand, so we put it there before we ask for a signature or a deposit. Call (805) 301-9518 to schedule yours - estimates are free.
Most Camarillo homeowners who call this week get an assessment within 3-5 business days, depending on current project load. We don’t overbook; we’d rather tell you “next Tuesday” and show up than promise “tomorrow” and reschedule. You’ll know your window when you call. Call (805) 301-9518 to check this week’s availability.
No. Our standard assessment hours extend until 8 PM weekdays and include full weekend availability, all at the same rate. We don’t penalize homeowners who can’t leave work early to meet us. The price in your written estimate reflects the work, not the clock.
Your Camarillo property address, a rough idea of your budget range, and what you’re trying to build - a studio, a one-bedroom, a two-bedroom with kitchen. If you have a survey or recent plot plan, great, but we don’t need it to schedule. We’ll measure everything ourselves during the assessment. Call (805) 301-9518 when you have 10 minutes to talk through your project.
We accept check, ACH transfer, and all major credit cards. For ADU construction, we structure payments to milestones - typically design completion, permit issuance, foundation completion, and final walkthrough - so you’re never paying far ahead of work performed. Your written estimate spells out every draw amount and trigger. Call (805) 301-9518 to discuss payment timing for your specific project.

No pressure, no deposit to get on the calendar, just a written number you can take to your lender or your family and compare.
