Adding an ADU in Studio City usually costs between $195,000 and $385,000 for a detached unit, depending on your lot, your finish level, and whether your parcel sits north of Ventura Blvd in the hillside zone or down in the flatlands. That’s a real number, not a teaser, and it’s the number you should have in your head before you talk to any contractor. Our crews know the difference between a hillside build on Dilling Street and a flat-lot garage conversion off Moorpark, because those two projects share almost nothing except a zip code. If you’re serious about an ADU in Studio City, call (903) 568-7222 and we’ll put a written scope and price in front of you, not a verbal guess.
Why Benson ADU Builders Is Studio City’s Preferred ADU Builders Company
Most Studio City homeowners who call us have already talked to someone else. The story is usually the same: a verbal estimate, a vague timeline, and no written breakdown of what the hillside grading, fire-zone detailing, or permit fees actually cost. That changes the day you call. Troy Eastman, who leads Benson ADU Builders, structured this company around one idea: a written price before any work starts, and a 365-Day Done Right Promise stamped on every job. If it’s not right within a year, we make it right.
We’re part of the Relay Home Co. family, founded in 2006, and each location operates independently under The Relay Visibility Guarantee. That means a live person answers every call, our technicians are background-checked and arrive in uniform, and you get real-time tracking on your build. For Studio City homeowners, that level of visibility is rare, because so many ADU contractors in this market still run jobs from a truck and a clipboard. We run ours from a written schedule you can see.
Backyard ADU in Studio City
A Backyard ADU in Studio City is a detached living unit built behind the main house, typically 400 to 800 square feet, with its own kitchen, bath, and entrance. On a flat lot near Tujunga Village or Colfax Meadows, this is often a straightforward build. On a hillside lot above Ventura Blvd, it’s an engineered project, because the rear portion of many Studio City parcels slopes more than 15 percent and sits inside a Very High Fire Hazard Severity Zone. That doesn’t make the project impossible. It makes the upfront scope and price the most important part of the job.
Foundation and Slope Work
Hillside lots in Studio City often need a pier-and-grade-beam foundation rather than a simple slab. Piers go down to solid bearing soil, and the grade beam spans between them so the structure doesn’t shift with the slope. We price this work before we dig, not after. If your lot is flat, you skip this cost entirely.
Fire-Zone Exterior Detailing
Studio City parcels in the Very High Fire Hazard Severity Zone require ignition-resistant siding, ember-resistant vents, and Class A roofing. We specify James Hardie fiber-cement siding on most hillside ADUs because it meets the code requirement and stands up to decades of sun and Santa Ana wind cycles. This is not an upgrade. It’s a building code requirement, and it gets priced into your written estimate from day one.
ADU Construction in Studio City
ADU Construction in Studio City runs from concept to certificate of occupancy, and the honest range for a site-built detached unit here is $205,000 to $385,000. A garage conversion or a Junior ADU inside the existing home footprint lands lower, typically $120,000 to $190,000, because there’s no new foundation and far less site work. The two biggest cost drivers on Studio City projects are slope and fire-zone compliance, not square footage. A 600-square-foot hillside ADU can cost more than an 800-square-foot flatland unit, and that surprises almost every homeowner who has only seen flat-lot pricing online.
Permit and Plan Check Realities
Studio City falls under Los Angeles city permitting, and hillside parcels trigger Baseline Hillside Ordinance review. That means grading caps, floor-area ratio limits, and plan check comments that a flat-lot ADU never sees. We pull permits, respond to plan check, and pass inspections as part of the job, not as an afterthought.
Prefab vs Site-Built on Hillside Lots
Panelized systems from Cover, Dvele, and Boxabl work on some Studio City lots, but the advertised package price rarely includes hillside grading, crane placement, or fire-zone upgrades. We walk you through the real all-in number before you sign anything. If prefab makes sense for your parcel, we say so. If it costs more than site-built once the hillside work is priced in, we tell you that too.
Trusted Brands We Service in Studio City
Benson ADU Builders is authorized to build with Dvele, Cover, and Boxabl, and we stock the common James Hardie cladding lines local to our Studio City service area, so supply chain delays don’t stall your finish work. Every brand we offer is one you can research independently: Dvele’s panelized shells, Cover’s precision-fabricated modules, Boxabl’s fold-out units. We don’t push a single product. We show you which system fits your lot, your slope, and your fire-zone requirements, then put the full number in writing.
Common ADU Builders Problems We See in Studio City Homes
- Flat-lot templates on hillside parcels. A contractor prices your ADU from a Valley flat-lot spreadsheet, then discovers the grade change and Baseline Hillside Ordinance limits during excavation. The price jumps, and you’re stuck.
- Fire-zone costs appearing after plan check. Ember-resistant vents, ignition-resistant siding, Class A roofing. These are code requirements on many Studio City hillside lots, and they need to be in your first written number, not a change order after the city comments.
- Prefab pricing without site work. A Brand-name prefab package looks affordable until the crane, grading, and foundation costs land on top. The real price only works when the hillside work is priced in up front.
- No written scope before demo. A verbal estimate is not a contract. Homeowners on tight Studio City lots with limited access need a line-item written price, because surprise excavation and debris removal change the budget fast.

FAQs About ADU Builders in Studio City
Yes. A hillside ADU on a parcel above Ventura Blvd typically costs 25 to 45 percent more than the same square footage on a flat Valley lot because of foundation engineering, grading, and fire-zone code requirements. The Baseline Hillside Ordinance caps grading and floor-area ratios on these parcels, and Very High Fire Hazard Severity Zone rules mandate ignition-resistant materials. A 600-square-foot hillside ADU in Studio City can run $240,000 to $310,000, while a similar flat-lot build might land at $195,000 to $230,000. Call (903) 568-7222 for an exact number on your specific lot.
A Studio City ADU requires city of Los Angeles building permits, and hillside parcels often need additional grading plan review under the Baseline Hillside Ordinance. If your lot sits in a Very High Fire Hazard Severity Zone, plan check will also verify ignition-resistant construction details. We handle every permit, respond to every plan check comment, and schedule every inspection as part of the job. Call (903) 568-7222 and we’ll walk you through exactly what your parcel triggers.
A flat-lot detached ADU in Studio City usually takes 7 to 10 months from first call to move-in, including design, permits, and construction. A hillside ADU adds 2 to 4 months because grading plan review and foundation engineering take longer. Prefab systems can compress the construction phase, but the permit timeline doesn’t change much. We give you a written schedule with your written price, so you know the calendar before you commit. Call (903) 568-7222 for a realistic timeline on your parcel.
Yes, on many lots. We’re authorized to build with Dvele, Cover, and Boxabl, and these systems work well on flat or gently sloping Studio City parcels. On steep hillside lots, the foundation, grading, and crane placement costs can erase the prefab price advantage, and we’ll show you that math in writing before you choose. The package price is never the all-in price. Call (903) 568-7222 and we’ll compare prefab versus site-built for your specific lot.
Nothing, unless you change the scope. Your written price under The Relay Visibility Guarantee includes the slopes, the fire-zone detailing, the permits, and the finishes you selected. The only price changes on a Benson project are changes you request, in writing, before the work proceeds. We built a 600-square-foot detached ADU on Dilling Street with zero change orders, because the hillside foundation and James Hardie fire-zone cladding were priced in from the first written estimate. Call (903) 568-7222 and get that same written certainty for your Studio City ADU.
