Serving 90077 and Beverly Hills, Brentwood, Holmby Hills
Your garage is probably the most under-used 400 square feet on your lot. Garage conversions transform it into livable square footage — a home office, studio, guest suite, gym, or full Junior ADU. California's ADU law specifically protects garage conversions, so the path is faster than most homeowners expect. We handle insulation, drywall, electrical upgrades, HVAC, plumbing, finishes, and permits, end to end.
Every neighborhood has its own architectural character, permit jurisdiction, and finish-level expectations. Here's how we approach garage conversion in Bel Air specifically.
Many Bel Air homes sit on caissons or stepped foundations on slopes. Structural changes require careful engineering review. We bring in licensed structural engineers early — never as an afterthought.
Narrow private roads, gated entrances, and limited staging area mean material deliveries get scheduled around access windows. We plan logistics into the timeline, not bolted on.
Many Bel Air clients have long-standing relationships with architects, landscape designers, AV integrators, and security firms. We integrate with whoever you have — we don't insist on bringing our own team if yours is in place.
A common Bel Air parcel configuration places the garage detached and down-driveway, separated from the main house by a paved approach. That changes the garage-conversion plumbing math: tying into the main house sewer line can require trenching across the driveway, which means either saw-cutting and repouring driveway sections or running an alternative line. The right path depends on the specific driveway material, length, and existing utility routing. We map the existing utility paths on the site survey before we quote scope so the conversion plan accounts for the real-world tie-in route.
Older Bel Air detached garages were often built to lighter load specifications than today's habitable-room code requires, particularly when the slab is hillside-supported. A garage conversion to ADU or guest suite typically triggers slab inspection, sometimes underpinning or replacement, plus shear-wall additions for the hillside-facing walls. We assess the existing slab and framing in the first weeks of design, before any demo, so the structural scope is in the budget rather than discovered after the project is already under way.
Beyond state ADU-law parking preemptions, certain Bel Air parcels can have HOA or municipal-overlay considerations affecting curb cuts, drainage, paving setbacks, or design review on landmark-influenced sub-areas. State ADU law overrides much of this, but local enforcement varies and is best confirmed against the specific parcel's zoning records rather than assumed from an LA-wide pattern. We verify the specific parcel's overlay status as part of feasibility, before permit submission, so the conversion doesn't hit an avoidable correction notice mid-review.
We help you decide whether the conversion should be permitted as livable space, an office, or a full JADU/ADU — each has different code requirements and resale implications.
Garage walls and ceilings are typically uninsulated. We bring the envelope up to code: insulation, vapor barrier, weatherized doors/windows, and air sealing.
New circuits, lighting, HVAC (mini-split or extension of central system), and plumbing if you're adding a kitchenette or bath.
Drywall, flooring, doors, windows, paint, and built-ins. We'll match interior detail to your main home or distinguish it intentionally if it's a separate unit.
Garage conversions almost always require permits. We pull them, schedule inspections, and clean up the paperwork.
Typical LA garage conversion range. Lower end = single-room conversion (office, studio). Higher end = full JADU with kitchen, bath, and separate entrance.
LA Department of Building and Safety (LADBS) handles Bel Air permits. Hillside-zone properties trigger additional grading review and slope-stability requirements. Plan check timelines: 6–12 weeks for kitchens, longer for hillside structural work.

Free consult, no obligation. Onn personally reviews every inquiry — usually replies within 1 business day.
Yes, if you're changing it to livable use (heated space, occupiable per code). Permits cover insulation, electrical, plumbing, and any structural changes. We handle them.
California state law removed the requirement to replace lost off-street parking when converting a garage to an ADU. Most LA jurisdictions follow that. Verify with your municipality if you're close to a transit corridor or street parking is restricted.
Yes. We've done full-home projects in that range and approach them with project management appropriate to the scale — multiple subcontractors running in parallel, weekly milestone reporting, and a single accountable PM (Onn).
Absolutely. Many clients come to us with plans already drawn. We pick up at construction documents, run the build phase, and coordinate inspections.
