Garage Conversion ADU in West Hollywood - Design, Permits and Build Under One Contract

Fast, Reliable Garage Conversion ADU Across West Hollywood

A garage conversion ADU in West Hollywood typically runs $95,000-$175,000 all-in, drawings through final inspection, and takes 6-10 months from signed contract to certificate of occupancy. Our Garage Conversion ADU team coordinates permitting through West Hollywood Community Development at 8300 Santa Monica Blvd, not the LA City portal, because WeHo is its own municipal jurisdiction with its own plan-check staff and correction formats. Dispatch and scheduling are coordinated from our Los Angeles office; crews serve West Hollywood locally and understand the street-by-street parcel boundaries that flip between WeHo and LA City.

Why Ellery ADU Studio North Hollywood Is West Hollywood’s Preferred Garage Conversion ADU Company

We’ve designed, permitted, and built ADUs across greater Los Angeles since 2015 - the year California’s ADU laws shifted - and West Hollywood ADU Design & Permitting remains one of the most specialized markets we serve given tight parcel sizes, rent-control landscape, and a separate municipal planning counter. Our 900+ completed ADUs include dozens of garage conversions in WeHo’s bungalow courts, dingbat apartments, and hillside-adjacent single-family pockets.

West Hollywood clients receive the same documentation standard as every Ellery project: a written price before any work starts (Haven Standard, Clause 1), a documented photo record on every site visit, and the 365-Day Done Right Promise backed in writing. A live person answers calls 24/7. We also offer a Free Second Opinion on any written estimate already in hand.

Our familiarity with WeHo’s specific conditions means we price the real job, not the walkthrough fantasy. We know what opening a 1920s-1960s garage shell typically reveals, and we write those contingencies into the contract as line-item allowances - not surprises.

Our Garage Conversion ADU Services in West Hollywood

Attached Garage Conversion

Attached garages in West Hollywood’s Spanish Colonial and Craftsman homes along Hammond Street and the West Hollywood West neighborhood often share a wall with the primary residence, which simplifies utility tie-ins but complicates firewall separation and sound transmission. We handle the Title 24 energy compliance, the separate meter or sub-meter question, and the egress window sizing that WeHo’s plan checker will flag. Typical range: $110,000-$165,000.

Detached Garage Conversion

Detached garages are rarer in West Hollywood’s sub-7,000-sq-ft lots, but they do exist in the Norma Triangle and on some Sunset Strip hillside parcels. These conversions require trenching for sewer and water, and often trigger setback re-interpretations because the existing structure may predate current codes. We verify the parcel’s zoning at 8300 Santa Monica Blvd before we price the job. Typical range: $125,000-$175,000.

Carport Conversion

Carport-to-ADU conversions are common in WeHo’s 1950s-1960s dingbat apartments, where tuck-under soft-story parking was original construction. The prior soft-story retrofit (mandated by WeHo’s seismic program) often complicates the new ADU’s shear-wall layout; our permit set addresses this directly rather than hoping the plan checker misses it. Typical range: $95,000-$145,000.

Garage Partition & Bathroom Add

Some West Hollywood landlords want to split an oversized two-car garage into a JADU plus remaining storage, or add a bathroom to a converted space that was previously unpermitted. We document the existing as-built condition, determine whether the partition triggers additional parking replacement under WeHo’s local ADU ordinance, and engineer the wet-wall stack for the new bath. Typical range: $85,000-$140,000 depending on plumbing distance.

Garage JADU

The garage JADU is the most common project type we see in West Hollywood. Under 500 square feet, no separate parking replacement required, and - critically for WeHo landlords - explicitly exempt from the city’s municipal rent control under AB 68. Our crew converted a tuck-under soft-story garage on a 1940s duplex in the Norma Triangle: the first inspection exposed aluminum branch wiring, a rotted sill plate from a failed 20-year-old deck flashing, and framing that had been notched for the original garage door header. We’d already written the potential remediation into our contract line items; the corrected work was priced in writing and approved by the owner before our tech touched a single stud, and the finished 480-sq-ft JADU passed WeHo Community Development plan check on the first correction cycle. Typical range: $95,000-$135,000.

Trusted Brands We Service in West Hollywood

Ellery specifies and coordinates prefab and modular systems from Abodu, Cover, and Mighty Buildings within the same single contract that covers your design, permit set, and construction. For West Hollywood’s tight lots and hillside access constraints, we evaluate whether a modular delivery is feasible given crane placement and street closure rules on your specific block. When site conditions favor stick-built, we source James Hardie siding and Tuff Shed structural components through our standard supply chain. Every specification is documented in the permit set and locked at signing under Haven Standard, Clause 5 (No Surprises).

Common Garage Conversion ADU Problems We See in West Hollywood Homes

• Undisclosed electrical systems. Opening a 1920s-1940s garage shell and finding knob-and-tube or aluminum branch wiring, neither of which is visible at walkthrough but both of which a WeHo permit triggers once walls are open. We inspect accessible panels during our initial site visit and write remediation allowances into the contract.
• Soft-story framing complications. Tuck-under garage framing that was previously retrofitted or notched for a tuck-under opening, leaving shear/elevation issues that a plan checker flags after the ADU conversion drawings are submitted. Our structural engineer reviews the soft-story report before submittal to catch this.
• Failed waterproofing at grade. Failed waterproofing at the existing stoop, deck flashing, or grade line against the garage stem wall undermines the new ADU’s floor assembly and triggers a WUI ember-resistance review for hillside-adjacent parcels in the Norma Triangle and Sunset Strip.
• Slabs without moisture barriers. Cast-iron drains and a slab that never had a moisture barrier are standard in pre-1960s construction. The new ADU’s finished flooring assembly requires vapor management we price as a line item, not a change order.
