Contact Ellery ADU Studio Thousand Oaks - Free ADU Estimate in Thousand Oaks
Call (424) 395-4555 to schedule your free ADU estimate in Thousand Oaks. When you reach us, a live coordinator will connect you with our local team. There’s no hard sell, no deposit required to book the assessment, and we can usually schedule your site visit within a few days. We’ll walk your property, take measurements, and talk through what you actually want to build.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up, notes your address in Thousand Oaks or nearby, and asks what you’re hoping to build - a detached studio, a garage conversion, a junior ADU. You’ll get a sense right away whether we’re a fit. If your lot’s slope or setback looks tricky, we’ll flag it early rather than waste your time.
Step 2: We schedule the site assessment. We book a 60- to 90-minute walkthrough with a local designer who knows Ventura County zoning. You’ll receive a calendar invite and a text reminder the day before. We show up in the window we promised.
Step 3: You get a written estimate. Within five business days, we deliver a line-item quote: design, permit set, construction, and fixed-price options for materials like James Hardie siding or a Tuff Shed foundation package. The price we write is the price you pay. Clause 1 of the Haven Standard requires it.
Step 4: We build to the drawings. Once you sign, we handle the permit submission to Thousand Oaks Planning, schedule inspections, and assign a verified crew. You get photo documentation at each phase and a final walkthrough with evidence of completed work.
Why Thousand Oaks Homeowners Call Us First
- Local response, not a dispatch queue. Our team lives and works in the Conejo Valley. We know the difference between a flat lot in Westlake Village and a hillside build in Oak Park that needs a soils report. That local knowledge saves weeks on permits.
- Required licensing and insurance, documented. Every pro working under our name is required to hold the license and insurance California requires for ADU construction. We put license numbers in your contract, not just on a truck door.
- Transparent pricing with no hidden fees. Your written estimate breaks out design, permits, materials, and labor. If we hit rock during excavation or discover an unpermitted patio cover, we document it, price it, and get your signature before spending your money.
- The Haven Standard workmanship guarantee. Every ADU we build in Thousand Oaks carries a written warranty backed by the brand that has permitted and built 900-plus units since 2015. Clause 4 requires photo evidence of what we found and what we fixed.
Our Service Area Around Thousand Oaks
We design and build ADUs throughout Ventura County and the western San Fernando Valley. Typical response times: Westlake Village and Oak Park, same day; Moorpark and Agoura Hills, next day; Simi Valley and Camarillo, within 48 hours; Malibu and Calabasas, two to three days; West Hills, Canoga Park, and Fillmore, three to four days. If you’re outside these areas - Santa Paula, Piru, or deeper into the Valley - call anyway. We’ve traveled for the right project, and we’ll tell you honestly whether your distance affects scheduling or pricing.
Frequently Asked Questions - Booking & Estimates
Yes. The site assessment and written estimate cost nothing and obligate you to nothing. We believe you should see real numbers before deciding, which is why Clause 1 of the Haven Standard exists. Call (424) 395-4555 to book yours.
We typically schedule site assessments within three to five business days, sometimes sooner depending on current project load. We don’t promise same-day visits for estimates because a proper assessment takes time we won’t rush. Call (424) 395-4555 and we’ll find the next available slot.
No. We don’t add surcharges for Saturday site visits or evening calls to review your estimate. Our published hours are 24 hours daily, seven days a week, though most assessments happen during standard business hours when city offices are open for permit questions.
Your address, a rough idea of the ADU size or type you want, and any known constraints - a septic system, a narrow driveway, HOA rules. If you have a recent survey or property plot, mention it. The more context you give, the more precise our preliminary guidance.
We accept checks, wire transfers, and major credit cards. The payment schedule is written into your contract: typically a design deposit, a construction deposit at permit approval, and progress draws tied to inspection milestones. No cash-only demands, no surprise payment requests.
