Contact Ellery ADU Studio Westchester - Free ADU Estimate in Westchester
Call us at (213) 698-7591 for a free ADU estimate in Westchester. You’ll reach a live coordinator who’ll connect you with our local team, not a hard sell. We’ll ask about your property, explain what’s possible under current Los Angeles codes, and schedule a site assessment at your convenience. Most Westchester homeowners hear back with a time within a few hours.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up, takes your address in Westchester or nearby, and notes what you’re after - a backyard cottage, garage conversion, or something custom. No scripts, no pressure to commit. We want to know if your lot qualifies and what you’re hoping to spend.
Step 2: We schedule a site assessment. Nadia Ellery or a senior designer walks your property, checks setbacks, utility access, and any oak trees or slope issues that affect design. We photograph what we find and measure twice. This visit is free and usually takes 45 minutes.
Step 3: You receive a written estimate. Within a few days, you get a line-item quote: design, permit set, construction, and finishes. One contract, one price. Clause 1 of our Haven Standard - Have it in writing - means no verbal ballpark that shifts later. You review, ask questions, and decide on your timeline.
Step 4: We permit, build, and finish to the drawings. Once you sign, we handle the Los Angeles Department of Building and Safety submittal, respond to corrections, and build what we drew. You get photo documentation at key phases and a final walkthrough with a written record of completion.
Why Westchester Homeowners Call Us First

- We’re local to Westchester. Our team lives and works between the 405 and the beach cities, so we know the specific constraints of LAX-adjacent lots, the Westchester-Playa Del Rey noise ordinance, and how LA Basin clay soil affects foundation design. Most assessments are scheduled within a few days of your call.
- Every pro is required to hold the license and insurance California requires. We verify coverage before anyone steps on your property, and license numbers appear on every contract. You’re not guessing who’s actually building your ADU.
- Transparent pricing with no hidden fees. Your written estimate breaks out design, permitting, construction, and finish allowances separately. If we hit unexpected conditions - say, unmapped utility lines near Kentwood Avenue - we document it, explain the change, and get your signature before spending more. No “while we’re in here” surprises.
- Workmanship backed by the Haven Standard. Every ADU we build in Westchester carries a written warranty, and we leave a documented record of what we found and what we did. That’s Clause 4 - Evidence on every job - and it’s how we’ve operated since Ellery was founded in 2015.
Our Service Area Around Westchester
We design and build ADUs throughout Westchester, Culver City, Inglewood, Venice, Hawthorne, Santa Monica, West Los Angeles, Gardena, Redondo Beach, Brentwood, and Beverly Hills. Response times vary by distance: Culver City and West Los Angeles typically within a day or two; Santa Monica and Venice about the same; Redondo Beach and Hawthorne usually within a few days. If you’re near these areas - say, Mar Vista, Playa Vista, or Lawndale - call anyway. We’ve assessed lots outside our core list when the project fits.
Frequently Asked Questions - Booking & Estimates

Yes. The site assessment and written estimate cost nothing and obligate you to nothing. We believe you can’t make a six-figure decision without a real number in hand, so we put one there before you pay anything. Call (213) 698-7591 to schedule yours.
We typically schedule assessments within a few days, sometimes sooner depending on current project load. We’re not a one-truck operation, but we’re not a volume factory either - Nadia Ellery reviews every site visit personally. Call (213) 698-7591 and we’ll find a time that works.
No. We schedule assessments when homeowners are home, including Saturdays. The estimate itself doesn’t change based on when we meet. Our published hours are seven days a week, so call whenever you have a few minutes to describe your project.
Your address, a rough idea of your budget range, and whether you’re considering a garage conversion, detached unit, or addition above an existing structure. If you have a survey or recent plot plan, great - but don’t delay calling if you don’t. We pull permits and records ourselves.
We accept check, wire transfer, and major credit cards. Large ADU projects are typically milestone-based: deposit at contract, draws at foundation completion, framing, and finish. Your written estimate specifies the schedule before you sign. Call (213) 698-7591 to discuss what works for your situation.
