Why Los Angeles Homeowners Choose Ellery ADU Studio Los Angeles for ADU
We’ve been building ADUs in Los Angeles since 2015, and our reputation here rests on one thing: every job starts with a written price and ends with a documented record. Homeowners across Culver City, Santa Monica, and Studio City come to us because they’ve seen what happens when design and build are split between two companies who can blame each other. We don’t split them. One contract. One price. One team accountable from the first sketch to the final inspection.
6 Reasons We’re Los Angeles’s Top ADU Company
1. We Know Los Angeles Permitting Like the Tradesmen Who Trained Us
California’s ADU law changed in 2015, the same year Ellery started. We’ve been navigating L.A.’s specific requirements since then - the hillside ordinances that affect Beverly Hills and West Hollywood, the coastal zone rules in Venice and Santa Monica, the fire department clearances that trip up first-time builders in Sherman Oaks. We know which plans get kicked back from the Department of Building and Safety, and we draw them right the first time.
In Westchester and Inglewood, we’ve learned which utility tie-ins require Southern California Edison coordination and which don’t. That local knowledge saves months. A designer in another state can’t know that the city of Los Angeles has different setback rules than Culver City, or that Hawthorne has its own inspection schedule. We do, because we’ve pulled permits in all of them.
Every pro working under our name is required to hold the license and insurance California requires. We don’t guess at code; we cite the specific section in your permit set.
2. Our Reputation Is Built on What We Can Show You
We don’t ask you to trust us because we’ve been around a while. We ask you to read our three-star reviews - the ones where something went wrong and you can see how we handled it. That’s the record that matters.
Our documentation system, part of The Haven Standard, means every homeowner gets photos and readings of what we actually found: the soil condition, the existing foundation, the utility capacity. You don’t have to take our word that the job was done right. The evidence is in your inbox before we leave the site.
We’ve worked in neighborhoods from Venice to Studio City long enough that our trucks are familiar sights. That familiarity is earned, not bought.
3. State-Licensed, Insured, and Background-Checked - Verified, Not Claimed
Every contractor in California is required to be licensed, but not every contractor makes it easy to verify. Under The Haven Standard, Clause 3, the license number of every pro on your job is documented before work starts. You can look it up with the Contractors State License Board yourself.
We’re insured and bonded to the levels California requires for residential construction. We don’t wave certificates; we add them to your project folder alongside the permit set and the written scope. Documentation is the whole point of Haven.
If a subcontractor works on your ADU in Santa Monica or Beverly Hills, their credentials are checked the same way. No exceptions.
4. Factory-Built Expertise: Abodu, Cover, and Dvele
Not every Los Angeles lot suits stick-built construction. Narrow access in Venice, tight hillside lots in West Hollywood, or speed requirements in Culver City - sometimes a factory-built unit from Abodu, Cover, or Dvele is the better path. We’ve worked with all three brands and know their respective strengths.
Abodu excels at rapid site preparation and crane-set delivery, which matters when you’re building in a dense neighborhood with limited street closure windows. Cover’s system integrates well with hillside foundations common in Sherman Oaks. Dvele’s smart-home integration appeals to the tech-forward buyers we see in Studio City and West Los Angeles.
We don’t push one brand. We specify the right system for your lot, your timeline, and your budget - and we price it in writing before anyone orders steel.
5. The Price on the Page Is the Price on the Permit
Clause 1 of The Haven Standard: Have it in writing. Every ADU job we quote in Los Angeles gets a flat price, written scope, and line-item breakdown before anyone starts. No “while we’re in here” additions. No scope creep disguised as discoveries.
We name the price range on the page, in dollars, because that’s what homeowners 32 to 50 in metro cores actually want. They bought between 2015 and 2025 at a high price. They’re not calling for a mystery number. They’re calling to confirm that our written estimate matches what they read.
If we find something unexpected - deteriorated soil in Hawthorne, an unpermitted addition in Inglewood - we document it with photos, cite the code section, and write a change order with a new flat price. You approve it or we don’t proceed. No surprises means no surprises.
6. The Haven Standard Warranty - Documented, Not Promised
Every ADU we build in Los Angeles carries The Haven Standard warranty, referenced by clause number in your contract. If something fails because of our work, we fix it. The documentation system that proved what we found also proves what we did, so there’s no argument about whether the crack was pre-existing or the leak was our joint.
We’re not going anywhere. Ellery has been building ADUs since 2015, and the Los Angeles branch is rooted here. Nadia Ellery leads this team, and the standards she works to are the same ones that govern every Ellery studio. The warranty is backed by a brand with 900+ completed ADUs, not a single operator who might retire.
Our Promise to You

If you’re not satisfied with any aspect of our work, we have a clear path: document the issue with photos, reference the specific Haven Standard clause, and we respond during our operating hours - Monday through Friday 7:00 AM to 7:30 PM, Saturday and Sunday 7:30 AM to 7:30 PM. A live coordinator answers our line and connects you with the local team, not a voicemail tree.
Our pricing transparency commitment is absolute. The written estimate you receive before work starts includes every permit fee we know of, every utility connection cost we’ve verified, and a contingency line for the unknowns we can’t predict. We don’t hide numbers in fine print. We put them in a table you can read.
Every ADU job is quoted in writing before it starts and leaves a documented record. That’s not marketing language. It’s Clause 1, and it’s stamped on every page we publish.
Frequently Asked Questions
We’re a design-build studio, not a designer who hands off to a contractor. When your ADU in Los Angeles goes over budget or misses a deadline, a split contract means each side blames the other. Our single contract means one accountable party from sketch to certificate of occupancy. We’ve been doing this since 2015, and our documentation system proves what we promised and what we delivered.

Yes. Every pro working under our name is required to hold the California contractor license and insurance the state requires, and we document those credentials in your project folder before work starts.
