Fast, Reliable Garage Conversion ADU Across Studio City
A garage conversion ADU in Studio City typically runs $95,000-$165,000 all-in for flatland ranch properties south of Ventura Boulevard, while hillside parcels above Fryman Road climb to $140,000-$220,000 once geotechnical reports, Chapter 7A fire-resistant assemblies, and sewer lateral upgrades are factored. Every project is quoted at a single written price before any work begins, per Haven Standard Clause 1. Call (424) 551-7706 to schedule your free estimate.
We’ve worked the post-war ranch blocks near Colfax Avenue, the steep parcels climbing toward Mulholland, and everything in between. Our Garage Conversion ADU team knows which side of Ventura you’re on changes what your permit set looks like, what LA Department of Building and Safety will ask for, and what your final invoice will be. Dispatch and scheduling are coordinated from our Los Angeles office; crews serve Studio City locally and carry the same license number on every truck.
Why Ellery ADU Studio Los Angeles Is Studio City’s Preferred Garage Conversion ADU Company
We’ve designed, permitted, and built 900+ ADUs since 2015, the year California’s ADU laws shifted. Every one had a written price before work started and a documented photo record when complete. Studio City homeowners find us because they’ve already read the three-star reviews - the ones where the designer blamed the builder, or the permit sat in correction for eight months. Our model eliminates that gap: one contract, one price, one party responsible.
Studio City clients receive the same documentation we provide everywhere - permit set, photo record, written warranty - but the local knowledge is what saves them money. We know that a detached garage on a 6,000 sq ft lot near Moorpark Street can often convert by right even if it sits inside the setback, while the identical structure on a hillside lot off Laurel Canyon Boulevard triggers a full geotechnical review. That distinction, made early, prevents the redesigns and delays that destroy budgets.
A live person answers calls 24/7. No voicemail queue, no callback promise that evaporates. And we offer a Free Second Opinion on any written estimate already in hand - bring us another firm’s scope and we’ll tell you what’s missing, what’s inflated, and what Studio City-specific conditions they’ve ignored.
Our Garage Conversion ADU Services in Studio City
Detached Garage Conversion
This is our most common Studio City project. The flatland ranch blocks between Ventura Boulevard and the LA River corridor hold thousands of detached single-car garages built between 1945 and 1965. Most sit 3-5 feet inside rear and side setbacks, which means under state law they can usually be converted to ADUs or JADUs by right - even when non-conforming. The price range here is $95,000-$145,000, drawings through final inspection. Hillside detached garages are a different scope entirely; see below.
Garage JADU
A Junior ADU carved from an existing garage must be under 500 sq ft and share utilities with the primary residence. In Studio City, this works best on flatland lots where the original garage shares a wall with the house or sits close enough for straightforward utility ties. We see strong demand for this near Tujunga Avenue, where owners want rental income without the full ADU budget. Typical range: $75,000-$110,000. The Haven Standard Clause 1 written price applies before we touch a wall.
Garage Partition & Bathroom Add
Some Studio City owners don’t need a full dwelling unit - they need a guest suite, home office, or rental-ready studio with its own bathroom and kitchenette. We partition existing garage volume, add wet walls, and run the plumbing without expanding the footprint. Critical on hillside lots where every square foot of new foundation triggers geotechnical review. Keeping work inside the existing envelope saves both time and money. Range: $65,000-$95,000 for flatland properties.
Attached Garage Conversion
Attached garages in Studio City’s post-war tracts are less common than detached, but they exist - particularly on corner lots where the garage faces the side street. These conversions require fire separation between the ADU and primary residence, which usually means a one-hour rated assembly and independent egress. We handle this in the permit set, not as a surprise during framing. Range: $85,000-$130,000.
Carport Conversion
Carport conversions in Studio City are less frequent but viable where the slab is adequate and the roof structure can be enclosed. The open sides complicate energy code compliance - Title 24 requires specific insulation and fenestration values - so we address this in the design phase, not after permit submission. Range: $55,000-$85,000 when the slab and posts are sound.

Trusted Brands We Coordinate in Studio City
Ellery specifies and coordinates prefab and modular systems from Abodu, Cover, and Mighty Buildings within the same single-contract model. For Studio City hillside lots where Chapter 7A fire-resistant assemblies are mandatory, we often pair Mighty Buildings’ fiber-reinforced polymer panels with ignition-resistant venting specified to the exact LA DBS interpretation. On flatland conversions where speed matters, Abodu’s pre-engineered units integrate cleanly with existing ranch foundations. Every system is priced in writing before ordering, per Haven Standard Clause 1.
Common Garage Conversion ADU Problems We See in Studio City Homes
- Mini-splits sized by square footage alone. A 400 sq ft garage does not automatically take a 9,000 BTU unit. In Studio City’s thermal bowl, where August afternoons hit 105°F, we run manual J load calculations that account for uninsulated slab, single-pane windows, and west-facing garage doors. Undersized equipment is the single most common complaint on completed units.
- Hillside conversions without geotechnical reports. Properties above Fryman Road fall inside the VHFHSZ. Contractors who submit permit drawings without Chapter 7A ember-resistant vents, Class A roofing, and one-hour fire-rated exterior walls receive correction notices from LA DBS mid-review. That adds weeks and forces expensive redesigns on projects already under construction.
- Original sewer laterals left in place. Flatland ranch homes often have 4-inch cast-iron laterals to the main, adequate for a single-family home but not for an ADU with its own kitchen and bath. LA DBS will not sign the certificate of occupancy on a converted structure tied to an undersized lateral. We verify capacity before quoting.
- Slab drainage assumed adequate. Pre-1965 garage slabs were poured without vapor barriers or proper slope. We test for moisture intrusion and drainage failure before framing starts, because fixing it after drywall is 4x the cost.

What moves you within these ranges? Foundation condition, whether the existing slab can be reused or needs replacement; utility distance and capacity, especially sewer lateral size and electrical panel capacity; hillside triggers, including geotechnical report, caisson or pier foundations, and Chapter 7A assemblies; and HVAC load, which in Studio City’s climate demands proper calculation, not guesswork.
Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing. No door-side upsells, no scope creep. The price you receive in writing is the price you pay. Call (424) 551-7706 for your free estimate.

FAQs - Garage Conversion ADU in Studio City
Yes, in most cases. On flatland ranch blocks south of Ventura Boulevard, detached garages built between 1945 and 1965 typically sit 3-5 feet inside setbacks but can still be converted by right under state ADU law, even when non-conforming. The key is confirming the lot is not in the VHFHSZ and that the garage is not on a hillside parcel where geotechnical triggers apply. Call (424) 551-7706 and we’ll verify your specific lot conditions before quoting.
Yes, if your property falls within the Very High Fire Hazard Severity Zone above roughly Fryman Road. LA DBS requires ember-resistant vents, Class A roofing, and one-hour fire-rated exterior wall assemblies for any ADU in this zone. Contractors who omit these items from permit drawings receive correction notices mid-review, adding weeks and forcing expensive redesigns. We flag this in our initial site visit and scope it into your written price. Call (424) 551-7706 for a free estimate.
Yes, substantially. Flatland ranch conversions south of Ventura Boulevard typically run $95,000-$145,000 with standard foundations and no fire-resistant assembly requirements. Hillside parcels above Fryman Road add $45,000-$75,000 for geotechnical reports, caisson or pier foundations, Chapter 7A construction, and often sewer lateral upgrades. We determine which path applies during our first site visit and quote accordingly. The written price reflects your actual conditions, not an average. Call (424) 551-7706 to schedule.
We run a full manual J load calculation, never square-footage rules of thumb. Studio City’s thermal bowl produces 100°F-plus summer days that overwhelm undersized equipment. On a 1948 ranch block near Colfax Avenue, we replaced a 9,000 BTU mini-split with a properly calculated 12,000 BTU unit with low-ambient kit - the difference between livable and unbearable by August. Your written scope includes the exact equipment specification and performance guarantee. Call (424) 551-7706 for an exact quote.
Yes, and we verify it before construction starts. LA DBS will not issue a certificate of occupancy on a converted structure tied to an undersized or failing lateral. Hillside properties climbing toward Mulholland are particularly prone to aging 4-inch laterals with inadequate slope or capacity. We coordinate the upgrade with LA Sanitation and scope it into your written price, not as a surprise after framing. Call (424) 551-7706 for a free estimate - we’ll inspect the lateral during our site visit.
