Fast, Reliable New Detached ADU Across Studio City
A new detached ADU in Studio City typically runs $320,000-$580,000 all-in, from permit set through final inspection, with hillside parcels in the Very High Fire Hazard Severity Zone landing at the higher end due to ignition-resistant materials and specialized venting. Our New Detached ADU team designs, permits, and builds under one contract at one written price, with drawings completed before construction starts so LADBS sees a coordinated set, not a guess. Call (424) 523-8492 to schedule your free estimate - every quote is itemized and fixed under Haven Standard, Clause 1.
We’ve worked the flatlands between Ventura Boulevard and Mulholland Drive, where 1950s ranch homes sit on rectangular lots with underutilized rear yards, and we’ve craned units onto steep hillside parcels in Fryman Estates off Laurel Canyon Boulevard where expansive soils and tight staging demand a different playbook. Our Los Angeles office coordinates dispatch and scheduling; crews serve Studio City locally and understand the permit rhythm at LADBS Metro, the fire-zone overlays that trigger additional review, and the neighbor dynamics that can make or break a tight-site project.
Why Ellery ADU Studio Van Nuys Is Studio City’s Preferred New Detached ADU Company
We’ve designed, permitted, and built 900+ ADUs since 2015, the year California’s ADU laws shifted, and a significant share of those have been in Studio City and the surrounding foothill communities. Our clients here are particular. They read the three-star reviews before they call. They want the permit set documented, the price written, and the crew background-checked. We deliver all three.
Our license number appears on every page, verified, not just claimed. Our crews wear uniforms and arrive with a documented photo record of what they find and what they do - not a summary of how it felt. Under Haven Standard, Clause 5 (No Surprises), the scope locks at signing. No door-side upsells. No scope creep.
Response time to Studio City is same-day for initial consultations, with permit sets typically delivered within 8-12 weeks of contract signing depending on LADBS queue depth. We know which Studio City parcels trigger hillside review, which require party-wall notice before demo, and how to stage a crane on a 40-foot driveway without blocking Radford Avenue traffic for three days.
Nadia Ellery, who leads the studio, reviews every permit set before it leaves our office. That’s not a figurehead claim - it’s the process that keeps our LADBS first-round approval rate above industry average.
Our New Detached ADU Services in Studio City

Custom Built ADU
Custom built ADUs in Studio City start around $380,000 and scale past $580,000 for hillside parcels with geotechnical complications and VHFHSZ detailing. We design from scratch for your specific lot - setback, slope, sun orientation, and that shared wall with the neighbor whose bedroom window sits twelve feet from your property line. Every custom project includes a full permit set, LADBS coordination, and construction under the same contract. On a recent project near Ventura Boulevard, we designed a 520-square-foot custom unit with a vaulted ceiling and clerestory windows to preserve the main house’s southern exposure. The permit set included fire-department access compliance and a landscape plan that satisfied the hillside overlay.

Prefab ADU Installation
Prefab ADU installation in Studio City typically runs $320,000-$450,000 depending on manufacturer, site access, and foundation requirements. We specify and coordinate systems from Abodu, Cover, and Dvele - brands whose modules we’ve craned onto lots from the flatlands to the lower slopes. Prefab works well on Studio City sites with clear driveway access and no overhead power-line conflicts. The catch: hillside parcels with steep approaches or tight turns off Laurel Canyon Boulevard may require a modular solution with smaller transport dimensions or a crane pick from the street. We evaluate access during our first site visit and tell you honestly if prefab is viable or if custom build is the smarter path.

Modular ADU
Modular ADUs in Studio City range $340,000-$480,000 and offer the precision of factory construction with site-specific adaptation. We’ve placed Mighty Buildings units on constrained lots where traditional framing would have required weeks of crew parking on a residential street. Modular shines when LADBS wants engineered drawings with stamped structural calculations - the factory provides them, and our team integrates the set with local geotechnical and fire-zone requirements. On a narrow Fryman Estates hillside lot off Laurel Canyon Boulevard, we craned a Modular ADU onto a redesigned footing after a geotechnical report flagged expansive soils, and the revised foundation plus crane staging pushed the project into a VHFHSZ-compliant envelope with Class A roofing and ember-resistant vents. The homeowner, a post-production editor, also had us frame STC 50+ acoustic walls and rough a 200-amp subpanel with fiber conduit so the unit could double as a mix room. Because the only staging option was the driveway and a neighbor’s shared wall sat within a few feet, we filed party-wall notice and scheduled all crane and concrete work inside Studio City’s permitted work hours.

Studio ADU
Studio ADUs - single-room detached units with kitchenette and bath - run $320,000-$420,000 in Studio City and suit homeowners who want rental income or guest space without the footprint of a one-bedroom. On the flatlands between Ventura and Moorpark, we’ve tucked studio ADUs behind existing homes with minimal setback variance. On hillside parcels, the same unit requires the same VHFHSZ detailing as larger builds, so the per-square-foot cost runs higher. We size the mechanical, electrical, and plumbing systems for the lot, not a catalog, and we specify tankless water heaters and mini-split HVAC that fit the compact footprint without overwhelming the main house’s existing service.

1-Bed & 2-Bed ADU
One-bedroom detached ADUs in Studio City typically start at $380,000; two-bedroom units range $420,000-$520,000 on flat lots, with hillside premiums adding 15-25 percent. The bedroom count drives septic or sewer capacity review, parking requirement calculations, and - on entertainment-industry lots - whether the electrical service can handle a 200-amp subpanel plus the main house load. We model all of this in the permit set, not after groundbreaking.

AfterTrusted Brands We Service in Studio City
We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie - all within the same single contract that covers design, permitting, and construction. For Studio City clients, this means we don’t hand you off to a manufacturer’s installer who hasn’t read your geotechnical report or filed your party-wall notice. We keep common replacement and finish components stocked for local projects, so when a hillside parcel requires upgraded venting or a specific Class A roofing assembly, we’re not waiting three weeks for a specialty order. The brands we recommend vary by site: Abodu and Cover for clean-lined flatland projects with straightforward access; Dvele and Mighty Buildings for precision-engineered hillside placements where factory tolerances reduce field adjustment time.
Common New Detached ADU Problems We See in Studio City Homes

- VHFHSZ plan rejection at LADBS. Filing a detached ADU without accounting for the Very High Fire Hazard Severity Zone ignition-resistant detailing - Class A roofing, ember-resistant venting, non-combustible or ignition-resistant siding - and having LADBS reject the plan set on hillside parcels. We catch this in preliminary site analysis, not after permit submission.
- Access and staging failures on tight lots. Underestimating access and staging on tight Studio City lots: no room for a crane or concrete truck, no neighbor agreement for shared-wall work, and no party-wall notice filed before demo starts. Our site evaluation measures turning radius, overhead clearance, and neighbor proximity before we quote.
- Missing the entertainment-industry spec. Quoting a standard flat-Valley ADU spec that misses the local entertainment-industry buildout - STC 50+ acoustic walls, a dedicated 200-amp subpanel, and fiber/production conduit rough-ins - then eating the change order. We ask the use case upfront and spec accordingly.
- Skipped geotechnical reports on hillside lots. Skipping the geotechnical report on steep, irregular hillside lots with older foundations and expansive soils, which stalls LADBS approval. We flag this requirement early and coordinate the report with our structural engineer so the permit set is complete on first submission.
Pricing for New Detached ADU in Studio City, CA
Studio City detached ADU pricing reflects three local realities: hillside versus flatland location, VHFHSZ compliance requirements, and the entertainment-industry buildout specifications that many clients request.
| ADU Type | Studio City Flatland Range | Studio City Hillside/VHFHSZ Range |
|---|---|---|
| Studio ADU (custom) | $320,000-$380,000 | $380,000-$450,000 |
| 1-Bed ADU (custom) | $380,000-$450,000 | $450,000-$520,000 |
| 2-Bed ADU (custom) | $420,000-$520,000 | $500,000-$620,000 |
| Prefab/Modular ADU | $320,000-$450,000 | $380,000-$480,000* |
*Hillside modular requires foundation adaptation and may shift toward custom pricing if access is constrained.
What moves the number: geotechnical report requirements ($4,500-$8,000), crane rental for tight sites ($3,500-$7,000), STC 50+ acoustic assemblies with decoupled framing ($15,000-$25,000 premium), 200-amp subpanel and production conduit rough-in ($8,000-$14,000), and VHFHSZ material upgrades ($12,000-$20,000). Every project is quoted with a written price before any work begins - Haven Standard, Clause 1. No “call for pricing.” No range that widens after you sign.

FAQs - New Detached ADU in Studio City

Yes. Hillside parcels in the Santa Monica Mountains foothills carry LA City’s Very High Fire Hazard Severity Zone designation, requiring ignition-resistant framing, Class A roofing, and ember-resistant venting that flat-Valley neighbors like Van Nuys or Reseda never face. These are permit requirements, not options, and LADBS will reject a plan set that omits them. We identify VHFHSZ status in our first site evaluation and build the detailing into the permit set from day one. Call (424) 523-8492 to confirm your parcel’s status and get an exact quote.
Sometimes. Prefab and modular installation depends on transport dimensions, crane reach, and overhead clearance - all of which we measure during site evaluation. On a recent Fryman Estates project off Laurel Canyon Boulevard, we used a modular unit with smaller transport dimensions and a street-based crane pick because the driveway couldn’t accommodate a full-size module delivery. If access is too constrained, we recommend custom build with stick-framing on site. We tell you which path works before you sign, not after. Call (424) 523-8492 to schedule a site evaluation.
Party-wall notice is a formal notification to adjacent property owners when construction work will occur within a specified distance of a shared property line wall or structure. In Studio City, where lots are narrow and homes sit close together, this is often required before demolition, foundation work, or any activity that could affect a neighbor’s structure. We file the notice, document delivery, and schedule work within permitted hours to maintain neighbor relations and avoid stop-work orders. The notice is part of our standard pre-construction checklist, not an afterthought. Call (424) 523-8492 and we’ll review your specific neighbor proximity.
Because CBS Studio Center on Radford anchors a dense entertainment-industry workforce, and many local homeowners use ADUs as production offices, editing suites, or mix rooms. STC 50+ acoustic wall assemblies block enough sound transmission for professional audio work, and a dedicated 200-amp subpanel with fiber conduit rough-in supports the equipment load and connectivity that standard residential ADU specs don’t address. This buildout profile is virtually unheard of in ADU projects a few miles north in Reseda or Panorama City, and it commands premium contracts that we quote accurately upfront. Call (424) 523-8492 to spec your unit for your actual use case.
Steep, irregular hillside lots with older foundations and expansive soils - common in Fryman Estates and other Santa Monica Mountains foothill neighborhoods - typically trigger a geotechnical report requirement before LADBS will approve an ADU. The report evaluates soil stability, slope integrity, and foundation design for the specific parcel. Flatland lots between Ventura Boulevard and Mulholland Drive with standard soils generally don’t require this step. We flag the requirement during preliminary site analysis and coordinate the report with our structural engineer so it doesn’t delay permitting. Call (424) 523-8492 to find out if your lot needs one.
