Our Garage Conversion ADU Services in West Hollywood

Attached Garage Conversion
Attached garage conversions dominate our West Hollywood workload because the city’s 1950s-60s dingbat apartments - those soft-story stucco buildings with open tuck-under parking along streets like Havenhurst Drive and Flores Street - simply don’t have backyard space to spare. Converting a ground-floor bay means opening shared walls with the main structure, which routinely surfaces cloth-wrapped wiring, undersized framing, and soft-story shear-wall deficiencies that a detached build never would. We inspect first, write allowances into the contract, and price any surprise in writing before we touch a stud.

Detached Garage Conversion
True detached garages are rare in West Hollywood’s multi-family fabric, but they do appear in the small single-family pocket near the Beverly Hills border and in some courtyard bungalow complexes off Melrose Avenue. When we find one, the project avoids shared-wall complications but still must navigate WeHo’s strict setback requirements - the distance between the converted structure and the property line. Our permit set includes every variance and height calculation before submission.

Carport Conversion
Carport conversions in West Hollywood typically involve enclosing an open parking structure attached to a dingbat or walk-up, often on parcels along Santa Monica Boulevard’s corridor. The existing slab and roof structure may carry the load, but the enclosure triggers full ADU code compliance: insulation, egress windows, and separate utility metering. We sequence the permit to capture any soft-story retrofit obligations that overlap with the same bay.

Garage Partition & Bathroom Add
Partitioning an oversized two-car tuck-under bay into a studio-plus-bath or one-bedroom ADU is common in West Hollywood’s larger 1960s courtyard complexes. The bathroom add means tying into existing sewer laterals - often cast-iron in this vintage - and venting through shared walls where clearances are tight. Our drawings specify every penetration and fire-separation detail before construction starts.

Garage JADU
A Junior ADU conversion inside an existing garage bay keeps the owner-occupancy requirement but avoids some of the full ADU parking-replacement rules. In West Hollywood’s RSO-covered buildings, this can be the safer compliance path when the garage space isn’t lease-listed as tenant parking. We verify the lease language before we draw the first plan.

Trusted Brands We Service in West Hollywood
Ellery specifies and coordinates prefab and modular systems from Cover, Dvele, and Mighty Buildings within the same single-contract design-build model. For West Hollywood’s tight sites where crane access is limited by narrow streets and overhead power lines, we often default to panelized or modular bathroom pods that minimize street closure time. Every system is priced in writing before ordering, with delivery and install sequenced around your permit approval.
Common Garage Conversion ADU Problems We See in West Hollywood Homes

- Soft-story deficiencies hidden behind finished walls. Opening a 1959 dingbat parking bay and finding missing hold-downs or rusted shear-panel connections is standard. We sequence the retrofit compliance with the ADU permit so you’re not paying for two separate mobilizations.
- RSO lease-listed parking triggering relocation obligations. A garage bay that appears on a tenant’s lease as included parking is a protected housing service under WeHo’s Rent Stabilization Ordinance. Converting it without proper notice and relocation compensation exposes the owner to violations that LARSO-covered buildings a block east wouldn’t face.
- Slab-level waterproofing failures from failed planter drains. Those north-facing tuck-under bays sit below grade-adjacent landscaping. Rust-stained concrete and efflorescence mean water’s been migrating for years. We fix the drainage before we frame walls.
- Heat-trapping masonry bays with no natural ventilation. West Hollywood’s dense urban flatland traps afternoon heat, and converted dingbat ground-floor bays - concrete-slab, often north-facing, surrounded by masonry - become unlivable without mechanical cooling. Mini-split systems are non-negotiable for habitability.

FAQs - Garage Conversion ADU in West Hollywood

Yes, nearly always. West Hollywood’s mandatory soft-story seismic retrofit ordinance covers most multi-family buildings with tuck-under parking built before 1978, which describes the majority of the city’s housing stock. The same ground-floor bay you’re converting is likely the same bay that needs shear-wall upgrades or hold-down installations. We coordinate both compliance tracks in one permit set and one construction sequence, so you’re not paying to mobilize twice. Call (424) 551-7706 to schedule an inspection that identifies both obligations upfront.
You can, but only after following WeHo’s Rent Stabilization & Housing department notice and relocation process. The RSO treats lease-listed parking as a protected housing service, separate from LA County’s rules. Removing it triggers just-cause obligations and mandatory relocation fees that routinely surprise ADU builders accustomed to working under LARSO just blocks away. We verify lease language during our initial documentation phase and build the notice timeline into the project schedule before demolition starts. Call (424) 551-7706 - we’ll review your lease documents as part of the free estimate.
Because 1950s-60s dingbat construction hides conditions no inspector can see: cloth-wrapped wiring that won’t pass a modern subpanel, rusted soft-story hold-downs, slab spalling from decades of planter-drain failure. The biggest quote mover is discovering these after demolition, when the owner has no leverage. We prevent this with a pre-demolition inspection, written allowances in the contract, and Haven Standard Clause 5: any surprise is priced and approved in writing before we touch it. Call (424) 551-7706 to see how our fixed-price change orders work.
Yes. West Hollywood’s dense urban flatland traps afternoon heat more than coastal neighborhoods, and converted dingbat ground-floor bays - concrete slab, often north-facing, surrounded by masonry - become stuffy without forced air. Mini-split heat pumps are effectively non-negotiable for habitability. We size and specify these in the permit set, not as a late add. Call (424) 551-7706 and we’ll show you the ventilation line item in your written quote.
West Hollywood’s 1.9-square-mile footprint is so densely built that usable yard space for detached units is nearly nonexistent on most parcels. The practical ADU path is interior or garage conversion, most commonly the tuck-under parking bays of those 1950s-60s dingbat buildings. Attempting a detached build usually means discovering the setback variance - the extra distance the city requires from the property line - eliminates the buildable area entirely. We assess this in the first site visit and tell you honestly if a garage conversion is your only viable path. Call (424) 551-7706 for that assessment.
