Fast, Reliable Garage Conversion ADU Across Sherman Oaks

A garage conversion ADU in Sherman Oaks typically runs $95,000-$185,000 all-in, from the permit set through final LADBS inspection, and the calendar is usually set by long-lead finishes rather than construction labor.

Why Ellery ADU Studio Glendale Is Sherman Oaks’s Preferred Garage Conversion ADU Company

We’ve completed over 900 ADUs across Los Angeles County since 2015, and a significant share of those have been garage conversions in Sherman Oaks’s 91403, 91423, and 91411 ZIP codes. Our clients here tend to be homeowners who bought between 2015 and 2025 at peak prices and are now converting detached two-car garages into rental income or family housing - they research extensively before calling, and they choose us because we name dollar ranges on the page and document every promise in writing.

Our response time to Sherman Oaks is same-day for initial consultations, and we maintain a documented photo record on every site visit - clients receive evidence of what we found and what we did, not a summary of how it felt. The 365-Day Done Right Promise is backed in writing before the project starts: if the finished ADU is not built to the permitted drawings, we make it right.

We’re familiar with the specific conditions that shape Sherman Oaks garage conversions: the 1950s-1960s ranch housing stock, the 60-100 amp electrical panels that almost always need upgrading, the San Fernando Valley heat that makes mini-splits a code necessity, and the sharp cost divide between flatland and hillside parcels. That local fluency means our permit sets move faster through LADBS and our quotes don’t surprise you mid-project.

Our Garage Conversion ADU Services in Sherman Oaks

Detached Garage Conversion

Detached garage conversions are the dominant ADU type in Sherman Oaks, and for good reason: most post-WWII ranch homes here have two-car garages set deep on 6,000-9,000 sq ft R1 lots, and LADBS’s streamlined ADU ordinance allows 4-foot rear and side setbacks with no discretionary review. We handle the full design-build sequence - measured drawings, permit set, foundation assessment, electrical upgrade, and finish - under one contract at one written price. On hillside parcels above Mulholland, we verify VHFHSZ status before specifying any exterior finish, since ignition-resistant assemblies, Class A roofing, and ember-resistant venting can add $15,000-$25,000 in materials alone.

Attached Garage Conversion

Attached garages in Sherman Oaks are common in the 1950s tracts near Kester Avenue and the flatter sections of 91411. These conversions require careful fire-separation detailing between the primary residence and the new ADU, and we engineer that separation into the permit set from day one. The shared wall often contains the original electrical service, so we coordinate the panel upgrade and new sub-metering simultaneously with the framing inspection. Every attached conversion gets the same written price guarantee and documented photo record as our detached work.

Garage Partition & Bathroom Add

Some Sherman Oaks homeowners don’t need a full ADU - they need a partitioned garage with a bathroom add for a home office, studio, or guest suite that stays under the JADU size threshold. We design these conversions with wet-wall plumbing stacks that tie into existing sewer lines, and we specify tankless water heaters when the original gas service can’t support a second full appliance load. The permit path is lighter than a full ADU, but the documentation standard is identical: written price, photo record, 365-Day Done Right Promise.

Garage JADU

A Garage JADU in Sherman Oaks is limited to 500 square feet and must be contained within the existing garage footprint, but it avoids the full ADU utility-separation requirements and can share bathroom and kitchen facilities with the primary residence in certain configurations. This is the right tool for homeowners on tighter lots near the 405 corridor who want rental income without the full construction scope. We assess whether your existing slab, headroom, and access meet JADU criteria during the initial consultation, and we quote the project in writing before any design hours are billed.

Carport Conversion

Carport conversions in Sherman Oaks are less common than garage conversions, but they appear in the hillside neighborhoods above Beverly Glen where carports were built into sloped driveways in the 1960s. These projects almost always need new foundations and enclosed walls, which pushes them toward full ADU scope rather than JADU. We evaluate the existing slab depth, drainage pattern, and hillside stability before quoting - and we quote in writing, with no open-ended allowances.

Trusted Brands We Service in Sherman Oaks

We specify and coordinate prefab and modular systems from Abodu, Cover, and Dvele within our single-contract design-build model, and we source James Hardie fiber-cement siding for custom garage conversions where the client wants a specific exterior finish that matches the primary residence. For Sherman Oaks projects, we maintain relationships with regional distributors who stock ignition-resistant assemblies and Class A roofing materials required for VHFHSZ parcels - this means we’re not waiting on special-order fire-rated materials when the permit is ready to pull. The brand specification happens during design, not as a post-permit surprise, and the price for every material is locked in writing before ordering.

Common Garage Conversion ADU Problems We See in Sherman Oaks Homes

• Foundation surprises on 1950s slabs. The post-WWII detached garages in Sherman Oaks were often poured as 4-inch non-structural slabs with no footing or rebar. We see contractors treat these as ADU-ready, then discover mid-project that the slab needs a full replacement after cabinets and glass are already ordered. We test the slab during our initial site visit and specify the foundation line item in the written quote.
• Electrical panels that can’t handle the load. Original 60-100 amp service was standard for Sherman Oaks ranch homes, and a new ADU with a mini-split, electric range, and tankless water heater typically needs 200 amps. We identify the panel upgrade requirement before permit submission and include it as a named line item, not a change order.
• VHFHSZ misclassification on hillside parcels. We’ve reviewed bids from other contractors who specified standard vinyl siding and conventional venting for garage conversions on streets above Mulholland, only to have LADBS reject the permit because the parcel sits in the Very High Fire Hazard Severity Zone. We verify VHFHSZ status at the address level before we specify a single finish.
• Long-lead items ordered before the price is fixed. Custom rift-oak millwork and architectural glass can carry 8-12 week lead times, and we’ve seen homeowners retain designers who order these items before the construction contract is signed - then absorb change-order costs when the design shifts mid-fabrication. We freeze the price in writing before any long-lead items are ordered, per Haven Standard, Clause 1.
