Fast, Reliable Garage Conversion ADU Across West Hollywood
A garage conversion ADU in West Hollywood typically runs $145,000-$285,000 all-in, drawings through final inspection, and takes 8-14 months depending on whether the project clears WeHo’s standalone plan-check on the first submittal. Our Garage Conversion ADU team coordinates dispatch from our Los Angeles office and serves West Hollywood properties directly, with crews who know the difference between LADBS rules and the city’s own checklist. Call (424) 523-8492 to schedule your free estimate - every project gets a written price before any work starts, per Haven Standard Clause 1.
Why Ellery ADU Studio Van Nuys Is West Hollywood’s Preferred Garage Conversion ADU Company
We’ve designed, permitted, and built ADUs across West Hollywood since 2015 - the year California’s ADU laws shifted - and our 900+ project archive includes dozens of garage conversions in the WeHo grid, from courtyard bungalows near Santa Monica Boulevard to Spanish Colonial Revival duplexes off Havenhurst Drive. West Hollywood homeowners review us for the documented photo record we deliver on every visit and the written scope that doesn’t change once signed.
Our crews respond to West Hollywood properties with the city’s specific plan-check requirements already loaded into the West Hollywood ADU Design & Permitting set, not LA City’s. That preparation matters because WeHo’s Community Development Department is a small, standalone office with its own timeline and checklist - contractors who assume over-the-counter fast-track rules routinely get sent back for revisions that add weeks.
Nadia Ellery built Ellery ADU Studio as a design-build practice precisely to close the designer-versus-builder blame gap that derails most ADU projects. One contract. One written price. One person accountable.
Our Garage Conversion ADU Services in West Hollywood
Detached Garage Conversion
Detached garage conversions are the most common ADU type we handle in West Hollywood, and for good reason: the city’s 1920s-1950s housing stock on lots under 6,500 sq ft usually includes a rear garage with its own footprint. We convert these into permitted studio or one-bedroom units with full kitchens and baths, running new electrical service, plumbing, and a dedicated mini-split for Title 24 compliance. Every detached conversion in WeHo needs its own plan-check submittal through the Community Development Department, not LADBS, and we prepare the permit set accordingly.
Attached Garage Conversion
Attached garages in West Hollywood’s courtyard bungalow complexes and post-war stucco buildings share a wall with the main structure, which changes the fire-separation and utility-tie-in requirements. We handle the structural analysis, the party-wall assessment if applicable, and the permit pathway that keeps the conversion code-compliant without disrupting the primary residence. These projects often trigger a full electrical service upgrade when we find the existing panel can’t support both units.
Garage Partition & Bathroom Add
Some West Hollywood homeowners want to keep part of the garage for storage or parking while converting the remainder into a habitable space. We design partition walls with proper fire ratings, add a bathroom and kitchenette to the converted portion, and ensure both zones meet egress and ventilation requirements. This is a popular option on tight lots near Melrose Avenue where losing the entire garage isn’t practical.
Garage JADU
A Junior ADU conversion keeps the garage within the existing walls but adds a small kitchen and separate entrance, without requiring the full utility separations of a standard ADU. West Hollywood’s RSO rules make JADU pathways worth examining carefully on lots with pre-1979 rental units, and we structure the permit application to avoid triggering relocation assistance requirements.
Carport Conversion
Carport conversions in West Hollywood face the same Title 24 energy compliance as garage conversions, but start from an open structure with no existing walls or slab edge to work with. We design enclosed wall assemblies, proper foundation connections, and the full utility package - electrical, plumbing, HVAC - to bring the finished unit up to certificate-of-occupancy standard.

AfterTrusted Brands We Service in West Hollywood
Ellery ADU Studio specifies and coordinates prefab and modular systems from Abodu, Cover, and Mighty Buildings within the same single contract that covers your design, permitting, and construction. For West Hollywood properties where a site-built conversion makes more sense, we source James Hardie siding and Tuff Shed structural components through our standard supply chain. Every material spec is written into the scope before work starts, with no door-side substitutions.
Common Garage Conversion ADU Problems We See in West Hollywood Homes
- Knob-and-tube or early Romex wiring. We open garages from the 1920s-1950s and find active knob-and-tube feeding the structure, or ungrounded Romex that fails modern safety standards. This forces a full electrical service upgrade before the ADU can receive its certificate of occupancy - a line item we pre-inspect for and write into the contract as an allowance.
- 60-amp panels with no capacity for HVAC and kitchen circuits. West Hollywood’s inland position in the basin produces hotter summer afternoons than coastal West LA, so detached garage conversions need dedicated mini-splits for Title 24 compliance and livability. A 60-amp panel can’t support that load plus the required kitchen and bathroom circuits.
- Failed slab-edge waterproofing and rotted sill plates. The age of WeHo’s housing stock means we routinely find moisture intrusion where the garage slab meets the wood framing. We price the repair in writing after exposing the condition, never bury it in a vague “contingency” percentage.
- Assuming LADBS rules apply. Contractors fluent in LA City’s process get sent back by WeHo’s Community Development Department for checklist items that LADBS would waive - setback interpretations, parking replacement triggers, or landscape plan requirements that don’t exist across the city boundary.

These ranges include design, permit set, plan-check fees, construction, and final inspection - the complete project, not a teaser rate that balloons. What moves a quote within these bands: the condition of existing wiring and framing, whether the slab needs repair, the finish level you select, and how many plan-check cycles WeHo’s Community Development Department requires. Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing; any condition we couldn’t see before opening walls gets priced and approved in writing before we proceed, not invoiced after the fact. Call (424) 523-8492 for your written estimate.

FAQs - Garage Conversion ADU in West Hollywood
West Hollywood operates its own Community Development Department, completely separate from LADBS. Your garage conversion ADU submits to WeHo’s standalone plan-check office with its own checklist and timeline, not LA City’s over-the-counter fast-track system. Contractors who assume LADBS rules apply get sent back for revisions that add weeks. Call (424) 523-8492 and we’ll confirm exactly which checklist your property triggers.
Yes, but the permit pathway must be structured carefully to avoid triggering West Hollywood’s rent stabilization ordinance relocation assistance and just-cause eviction requirements, which are stricter than LA City’s. We review your title report and existing tenancy status during design, then route the application to minimize RSO exposure. This compliance layer doesn’t exist the same way one block away in LA proper, and it’s why local expertise matters. Call (424) 523-8492 for a review of your specific situation.
West Hollywood’s 1920s-1950s housing stock routinely conceals knob-and-tube wiring, 60-amp panels, and failed slab-edge waterproofing behind finished surfaces. A contractor who writes a fixed bid without pre-inspection has to either inflate every quote to cover unknowns or eat the cost and cut corners. We pre-inspect where possible, write specific allowances into the contract, and price any surprise in writing before we build - so your final number is controlled, not guessed. Call (424) 523-8492 to schedule a pre-inspection with your estimate.
Yes. WeHo’s inland basin position produces summer afternoons significantly hotter than coastal West LA, and detached garages have no original insulation or HVAC. A dedicated mini-split system is required for Title 24 energy compliance and basic livability. We size the unit and specify the electrical circuit during design, so the panel capacity gets verified before construction starts. Call (424) 523-8492 and we’ll confirm the HVAC line item for your specific garage.
We stop work, document the condition with photos, price the repair in writing, and get your written approval before touching another stud. This is Haven Standard Clause 5 (No Surprises) in practice - not a verbal “it’ll be about this much,” but a written amendment with a fixed price. You approve it or we discuss alternatives; we don’t proceed on trust and invoice later. Call (424) 523-8492 to schedule your free estimate.
