Contact Ellery ADU Studio Lancaster - Free ADU Estimate in Lancaster
Call us at (661) 528-5298 to schedule your free ADU estimate in Lancaster. You’ll reach a live coordinator who’ll connect you with our local team, not a hard sell. We’ll ask about your property, your timeline, and what you’re hoping to build. Most Lancaster homeowners get an assessment scheduled within a day or two, and every estimate comes in writing with a fixed price before any work begins.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during business hours and takes down the basics: your address in Lancaster or nearby, what you’re considering (detached ADU, garage conversion, junior ADU), and when you’re free for an on-site assessment. No deposit, no commitment, no pressure to decide on the spot.
Step 2: We schedule your site assessment. Our local team visits your property in Lancaster, Quartz Hill, Palmdale, or wherever you’re located in the Antelope Valley. We measure, photograph, and check setbacks, utility access, and any oak trees or drainage issues that could affect your permit path. This takes about 45 minutes.
Step 3: You receive a written estimate. Within two business days, you get a line-item quote: design, permit set, construction, and finish. The price is fixed. That’s Haven Standard Clause 1 - Have it in writing - and it’s how we’ve operated since Ellery started in 2015.
Step 4: We build to the drawings. Once you approve, we pull permits, schedule crews, and execute. You get photo documentation at each phase, a named project lead, and a final walkthrough with readings and records of what we actually built. No surprises, no scope creep, no “while we’re in here.”
Why Lancaster Homeowners Call Us First

- We’re local to the Antelope Valley. Our team lives and works here, so we know Lancaster’s specific zoning, the city’s ADU ordinance updates, and how the high desert climate affects material choices. James Hardie siding, for instance, performs better than wood composites through our freeze-thaw cycles and Santa Ana wind seasons.
- Every pro on your job is required to hold the license and insurance California requires. We verify coverage before anyone steps on your property. License numbers go on your contract, and you can check them yourself.
- Transparent pricing with no hidden fees. Your written estimate includes every line item: design hours, permit fees, construction labor, materials, and finish. If we missed something, we eat it. That’s Haven Standard Clause 5 - No surprises - and it’s why our Lancaster clients refer us to neighbors.
- Workmanship backed by documentation. Every ADU job leaves a record: photos, measurements, material specs, and final readings. You get this file at closeout. It’s evidence of what we built, not just a promise that we did it right.

Frequently Asked Questions - Booking & Estimates

Yes. The on-site assessment and written estimate cost nothing. We believe you shouldn’t pay to find out what your project costs. Call (661) 528-5298 to schedule yours.
Most Lancaster assessments are scheduled within one to two business days of your call. We don’t overbook, so the date we give you is the date we arrive. Haven Standard Clause 2 - Arrive on schedule - means a real window, not a four-hour wait. Call (661) 528-5298 to check current availability.
No. Our rates are the same whether we assess your property on a Tuesday morning or a Saturday afternoon. We do schedule weekend assessments by appointment, and they carry no premium. Call (661) 528-5298 to find a time that works.
Your property address, a rough idea of your budget range, and any thoughts on size or style. If you have a survey, old plans, or photos of your backyard, great - but none of that is required. We’ll guide you through what we need to know. Call (661) 528-5298 when you’re ready.
We accept check, ACH transfer, and major credit cards. For construction projects, payment is tied to milestones defined in your written contract - typically design completion, permit approval, rough inspection, and final walkthrough. No lump sums upfront. Call (661) 528-5298 and we’ll walk you through the schedule for your specific project.
