Fast, Reliable New Detached ADU Across Studio City
A new detached ADU in Studio City typically runs $285,000-$520,000 all-in, from permit drawings through final inspection, depending on whether your lot sits on the flat post-war ranch tracts south of Ventura Boulevard or the hillside parcels above Fryman Road governed by LA City’s Hillside Construction Regulations and VHFHSZ requirements. Our New Detached ADU team designs, permits, and builds under one contract at one written price, with every project governed by The Haven Standard. Call (424) 551-7706 to schedule your free estimate.
We’ve worked the full span of Studio City, from the 6,000-square-foot ranch lots near Laurel Canyon Boulevard to the steep grades climbing toward Mulholland. Dispatch and scheduling are coordinated from our Los Angeles office, but our crews serve Studio City locally and understand the two entirely different permitting paths this city demands.
Why Ellery ADU Studio Los Angeles Is Studio City’s Preferred New Detached ADU Company
Studio City homeowners have hired us for 900+ ADU projects since 2015, the year California’s ADU laws shifted. Every one of those projects started with a written price before any work began, per Haven Standard Clause 1, and ended with a documented photo record of what was built.
Our license number appears on every page, verified, not just claimed. Background-checked, uniformed crews handle the work. A live person answers calls 24/7, no voicemail queue. And we offer a Free Second Opinion on any written estimate already in hand from another firm.
The 365-Day Done Right Promise is backed in writing before your project starts: if the finished ADU is not built to the permitted drawings, we make it right. This matters in Studio City, where hillside-versus-flatland complexity means the gap between promised and delivered work runs wider than in most LA markets.
Our New Detached ADU Services in Studio City

Custom Built ADU
Custom built ADUs in Studio City start around $320,000 on flat valley-floor lots and climb past $520,000 on hillside parcels requiring geotechnical reports, caisson foundations, and Chapter 7A ignition-resistant construction. We coordinate directly with your architect or interior designer, and we lock the finish schedule - custom millwork, architectural glass, specialty hardware - before ordering so lead times, not labor, set the calendar. On a steep lot off Fryman Road, we built a detached ADU clients wanted as a year-round guest house and home office, using a standing-seam metal roof and a custom rift-white-oak storage wall with a concealed pocket door. Because the site is in the VHFHSZ, our permit drawings had to show ember-resistant soffit vents and a one-hour fire-rated exterior wall assembly, and we coordinated the finish schedule with the owners’ interior designer so the lead times on the oak cabinetry and glass shower enclosure were locked before we ordered. The unit also got a correctly sized mini-split system for the San Fernando Valley thermal bowl, which keeps the small footprint comfortable through 100°F+ summer afternoons.

Prefab ADU Installation
Prefab ADU installation in Studio City typically runs $285,000-$380,000 on flat lots with straightforward utility ties. We specify and coordinate systems from Cover, Dvele, and Mighty Buildings within the same single contract that covers your permit set and site work. Hillside sites add foundation and access costs that prefab manufacturers rarely quote upfront. We flag these in writing before you sign, because Haven Standard Clause 5 locks the scope at signing with no door-side upsells.

Modular ADU
Modular ADUs in Studio City face a specific constraint: crane access and module delivery paths. The narrow, winding streets above Fryman Road often require module breakdown or crane positioning that flat-lot projects avoid. We map this in the preliminary site study and price it into the written quote. Modular construction in the 400-800 square foot range typically runs $295,000-$410,000 delivered and set on a flat lot.

Studio ADU & 1-Bed & 2-Bed ADU
Studio ADUs suit the smaller setback allowances on tight Studio City lots, particularly the 6,000-square-foot parcels common south of Ventura Boulevard. A 1-bed or 2-bed ADU needs more linear footage and often triggers additional parking or utility upgrades. Studio units typically run $285,000-$350,000; 1-bed units $310,000-$395,000; 2-bed units $340,000-$480,000, with hillside sites at the top of each range. Mini-split sizing is critical in all of these - Studio City sits in the thermal bowl of the San Fernando Valley where summer temperatures routinely push past 100°F, and undersized equipment is the single most common complaint on completed units.

Common New Detached ADU Problems We See in Studio City Homes

- Chapter 7A omissions on hillside plans. Submitting a hillside ADU plan without ember-resistant vents, Class A roofing, and one-hour fire-rated exterior walls triggers a correction notice from LA DBS mid-review and forces a redesign after construction is already underway. We flag this on day one.
- Flat-lot assumptions on steep parcels. Irregular or steep Studio City lots often require geotechnical reports, caisson or pier foundations, and an upgraded sewer lateral before the city will sign off on a certificate of occupancy. These are not optional add-ons; they are permit prerequisites.
- Undersized mini-split equipment. A detached ADU in Studio City’s thermal bowl with summer temperatures past 100°F needs correct load calculations. We size for the actual conditions, not the square footage alone.
- Finish schedules that ignore lead times. Custom millwork, architectural glass, and specialty hardware drive the calendar on high-end Studio City ADUs. We lock the finish schedule before ordering so your project doesn’t sit waiting on a six-week cabinet delivery.

FAQs - New Detached ADU in Studio City

Yes, if your parcel sits above roughly Fryman Road inside the Very High Fire Hazard Severity Zone. Your detached ADU must use ember-resistant vents, Class A roofing, and one-hour fire-rated exterior wall assemblies. Contractors who omit these details on permit drawings receive a correction notice from LA DBS mid-review, adding weeks and forcing expensive redesigns. We flag VHFHSZ status in our preliminary site study and price Chapter 7A compliance into the written quote from day one. Call (424) 551-7706 for an exact quote - estimates are free.
Hillside parcels require geotechnical reports, caisson or pier foundations, upgraded sewer laterals, and Chapter 7A ignition-resistant construction that flat-lot projects avoid. These are permit prerequisites, not upgrades. A flat-lot ADU south of Ventura Boulevard on a 6,000-square-foot ranch parcel typically starts around $285,000; the same footprint above Fryman Road often starts near $360,000. The divide is the defining cost variable in Studio City. Call (424) 551-7706 for an exact quote - estimates are free.
Standing-seam metal roofing performs well in the Santa Ana wind corridor that affects hillside parcels. For interiors, rift-sawn white oak and similar hardwoods handle the dry San Fernando Valley climate without the swelling issues common in coastal zones. We size mini-split systems for actual thermal load, not square footage alone, because 100°F+ afternoons will overwhelm undersized equipment. All finish selections are locked before ordering per Haven Standard Clause 5. Call (424) 551-7706 for an exact quote - estimates are free.
We coordinate the finish schedule with your architect or interior designer before any orders are placed, then lock the scope at signing per Haven Standard Clause 5. Custom millwork, architectural glass, and specialty hardware typically set the calendar, not framing or drywall. On the Fryman Road project, we ordered the rift-white-oak storage wall and glass shower enclosure eight weeks ahead of install to avoid a gap in the construction schedule. The written price covers this coordination - no change orders when lead times shift. Call (424) 551-7706 for an exact quote - estimates are free.
The flatland blocks between Ventura Boulevard and the LA River corridor hold single-story post-WWII ranch homes on 6,000-9,000 sq ft lots with detached single-car garages. These parcels typically accommodate a 400-800 square foot detached ADU under standard setback rules. Hillside parcels are irregular and must be measured individually for buildable envelope. A studio or 1-bed unit fits most flat lots; 2-bed units need more linear footage and often trigger utility upgrades. Call (424) 551-7706 for an exact quote - estimates are free.
