Fast, Reliable Garage Conversion ADU Across West Los Angeles
A garage conversion ADU in West Los Angeles typically runs $145,000-$285,000 all-in, from measured drawings through final LADBS inspection, with detached garage conversions on the higher end and attached or JADU partitions on the lower. Most West LA projects clear LADBS by-right approval in 8-14 weeks, but the real calendar driver is pre-permit discovery on the existing garage plus long-lead millwork and architectural glass. Call (424) 407-8266 to schedule your free estimate - every project gets a written price before any work starts, per Haven Standard Clause 1.
We serve West Los Angeles from our Los Angeles office, with crews working Palms, Mar Vista, Sawtelle, and Westwood-adjacent blocks weekly. The post-WWII housing stock here - stucco bungalows and ranch homes on 5,000-7,500 sq ft lots with alley-accessed detached garages - is structurally straightforward, but the existing garage conditions often aren’t. Our Garage Conversion ADU team knows what LADBS inspectors flag on these 1945-1975 structures because we’ve corrected it before the permit application on dozens of West LA projects.
Why Ellery ADU Studio North Hollywood Is West Los Angeles’s Preferred Garage Conversion ADU Company
We’ve designed, permitted, and built over 900 ADUs since 2015, the year California’s ADU laws shifted, and a significant share of those have been garage conversions in West Los Angeles. Homeowners in this market research deeply before calling - they read the three-star reviews, they compare permit timelines, they want the price on the page - and our reputation here is built on documentation, not slogans. Every client receives a written price before work starts, a documented photo record on every site visit, and the 365-Day Done Right Promise in writing.
Response time to West Los Angeles is same-day for initial consultations. We don’t promise what we can’t deliver: this is planned construction, not emergency service. What we do promise is that a live person answers calls 24/7 at (424) 407-8266, and that your estimate appointment includes a garage walk-through with a checklist of the LADBS pre-conditions we’ll need to clear.
Our crews understand West Los Angeles’s specific conditions: the coastal marine layer that keeps temperatures mild but wicks moisture through garage slabs, the alley-accessed detached garages in Palms and Mar Vista that prior owners often “bonus-roomed” without permits, and the premium rental market - $2,800-$4,500/month for a well-finished unit - that makes these conversions the most economically compelling ADU projects in Southern California. We coordinate Garage Conversion ADU in West Los Angeles from permit set through final punch, under one contract at one fixed price.
Our Garage Conversion ADU Services in West Los Angeles
Detached Garage Conversion
This is the dominant ADU type in Palms, Mar Vista, and Sawtelle, where alley-accessed two-car garages sit on 5,000-7,500 sq ft lots. A detached garage conversion in West Los Angeles typically runs $165,000-$285,000, depending on whether the existing slab needs reinforcement, whether the roof structure can carry a mini-split, and how extensive the code remediation is. On the high end, we specify custom rift-oak millwork, full-height architectural glass sliders, and designer-coordinated finishes - the millwork and glass lead times, not the framing, set the completion date. We fix the price in writing before ordering anything.
Attached Garage Conversion
Attached garages in Westwood and Brentwood-adjacent areas often connect to Spanish Colonial Revival or Mid-Century Modern homes where the conversion needs to read as intentional architecture, not a tacked-on rental. These projects run $145,000-$220,000 and require careful fire-separation detailing between the ADU and the primary residence. LADBS requires specific wall assemblies and door ratings; our permit set includes these details before construction starts, not as field fixes.
Garage Partition & Bathroom Add
For homeowners who want to retain garage parking while adding a JADU or partial rental unit, we partition the existing footprint and add a bathroom and kitchenette. In West Los Angeles, where parking minimums still matter for resale, this hybrid approach runs $95,000-$155,000. The plumbing rough-in and venting are the critical path items - many existing garages lack adequate drainage slope or vent stacks, and we identify this in the pre-application discovery so it doesn’t become a change order.
Garage JADU
A Junior ADU within an existing garage - under 500 sq ft, with owner-occupancy required in the primary residence - makes particular sense in Westwood and Brentwood-adjacent neighborhoods where lot sizes support larger homes but the owner wants rental income without full ADU construction costs. Garage JADUs in West Los Angeles run $85,000-$140,000. The JADU shares utilities with the main house, so our discovery includes load calculations and panel capacity; we don’t submit to LADBS until we know the electrical can handle it.
Carport Conversion
Less common in West Los Angeles’s core neighborhoods but present in some Sawtelle pockets, carport conversions require full enclosure, slab work, and roof modification. These run $125,000-$195,000 and face stricter setback scrutiny from LADBS. We handle the variance analysis in the design phase, not after the permit is rejected.

Trusted Brands We Service in West Los Angeles
Ellery ADU Studio specifies and coordinates prefab and modular systems from Abodu, Cover, and Dvele within the same single-contract framework that governs our custom builds. For West Los Angeles clients who want speed and predictability on a detached garage replacement rather than conversion, these systems arrive pre-engineered with LADBS-ready structural calculations. We also specify James Hardie siding assemblies on custom conversions where the exterior finish needs to match existing stucco or Spanish Colonial texture. Every brand selection is locked at the written-price stage - no mid-project substitutions without client sign-off and a documented change order.
Common Garage Conversion ADU Problems We See in West Los Angeles Homes
- Unpermitted electrical and mechanical in Palms and Mar Vista garages. Prior owners frequently added sub-panels, water heaters, or drywall without permits. LADBS will not accept an ADU application until these are brought to code. We budget a discovery-and-remediation allowance before permit submission so this doesn’t stall the project.
- Moisture wicking through unsealed garage slabs. West LA’s persistent coastal marine layer keeps temperatures mild but drives humidity into concrete. Finished floors laid directly on the slab without vapor barriers and ventilation detailing develop mold within two seasons. We specify sealed assemblies on every conversion.
- Long-lead materials ordered before pricing is fixed. Custom cabinetry and architectural glass ship on 8-14 week leads. If the price isn’t locked in writing before ordering, design changes mid-lead create cost and schedule drift that the client absorbs. We sign, then we order - Haven Standard Clause 1.
- Crews scheduled before material is on-site. On high-end West LA conversions, the calendar is set by millwork and glass lead times, not labor availability. We sequence trades only after material delivery is confirmed, so framers aren’t standing around waiting for a slider that hasn’t left the fabricator.
Pricing for Garage Conversion ADU in West Los Angeles, CA
Garage conversion ADUs in West Los Angeles typically run $145,000-$285,000 all-in, drawings through final inspection. Attached garage conversions and JADU partitions fall at the lower end; detached conversions with custom millwork, architectural glass, and designer coordination fall at the higher. The spread reflects three factors: the extent of pre-permit code remediation on the existing garage, the finish specification, and whether the project uses standard or long-lead materials.
What every West Los Angeles quote includes: measured as-built drawings, LADBS permit set, code remediation scope, structural and MEP rough-in, insulation and Title 24 compliance, finished flooring on a sealed slab assembly, kitchenette and bathroom fixtures, and final inspection. What it does not include: site work beyond the garage footprint, utility service upgrades to the main house, or landscaping. Those items are line-itemed separately if needed.
Under Haven Standard Clause 1, the price is written and fixed before any work begins. No “call for a quote” - the quote comes to you, in writing, at the estimate appointment. We also offer a Free Second Opinion on any written estimate already in hand. Call (424) 407-8266 for your free estimate.

FAQs - Garage Conversion ADU in West Los Angeles
Because the calendar is set by long-lead millwork and architectural glass, not by how fast the crew can frame. On a recent Mar Vista project, our rift-oak cabinetry and full-height glass slider shipped on 12-week leads; the framing took three weeks. We fixed the price in writing before ordering, so the lead time didn’t create cost drift. Call (424) 407-8266 for an exact quote on your project - estimates are free.
Yes, frequently. Contractors in these neighborhoods regularly find unpermitted sub-panels, unvented or unstrapped water heaters, and DIY drywall that violates current code. LADBS will reject the ADU application until these are corrected. Our standard process includes a discovery walk-through and remediation scope before permit submission. Call (424) 407-8266 to schedule yours - estimates are free.
No - not without a vapor barrier and ventilation detailing. West Los Angeles’s coastal marine layer drives persistent humidity that wicks through unsealed concrete and causes mold in finished living space. We specify sealed slab assemblies on every conversion. The added cost is minor compared to remediation. Call (424) 407-8266 for an exact quote - estimates are free.
Yes, particularly where lot sizes are larger and the owner wants rental income without full ADU construction costs. A garage JADU - under 500 sq ft, with owner-occupancy in the primary residence - runs $85,000-$140,000 in West Los Angeles and shares utilities with the main house. The key constraint is panel capacity; we verify this in discovery before submitting to LADBS. Call (424) 407-8266 for an exact quote - estimates are free.
We do. Ellery ADU Studio is a design-build studio, not a contractor - the drawings, permit set, and construction are a single contract at a single written price. The designer and builder cannot point at each other when something is off because they are the same entity. On high-end West LA projects, we coordinate directly with your architect or interior designer, or we provide in-house design services. The price is fixed before any long-lead items are ordered. Call (424) 407-8266 to schedule your free estimate.
