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 Beverly Hills specifically.
Beverly Hills runs its own building department (separate from LA City). Permit timelines and requirements differ from neighboring areas — designated historic homes have additional review. We handle the entire process so you don't have to navigate it.
Many BH homes are in landmark or historic-preservation zones with exterior alteration limits. We design around those constraints rather than fight them.
Beverly Hills clients typically expect high-end finishes — slab countertops, full custom cabinetry, high-grade appliances. We source through trade channels to keep finish quality high without unnecessary markup.
Beverly Hills B&S can restrict certain garage-conversion configurations that LADBS would allow, particularly when the garage is in the front setback or on a landmark property. State ADU law preempts some but not all of these restrictions, and the specific outcome depends on the parcel and the proposed configuration. We verify the specific parcel's eligibility for state-law preemption against the proposed conversion design before assuming a straight conversion will work.
Beverly Hills lot layouts frequently place the garage in the front-yard or front-side-yard position, attached to or adjacent to the main house. That affects conversion design: the converted space's windows face the street, which means privacy considerations and design-review attention on landmark parcels. We design garage-to-living-space conversions with deliberate fenestration that meets both the privacy needs of the new living space and the aesthetic expectations of the streetscape.
Beverly Hills clients generally finish converted garages at the same tier as the main house — hardwood floors, custom millwork, natural-stone bathrooms — rather than a rental-grade build. Less expensive options exist (basic conversion to home office or studio), but the prevailing local expectation is main-house parity. We scope the conversion to match the surrounding home's finish level so the converted space doesn't feel like an outbuilding stitched onto the house.
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.
City of Beverly Hills Building & Safety handles all permits — separate from LA County. Plan checks typically run 3–6 weeks for kitchen remodels, longer for structural work or historic-zone properties.

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.
Plan for 4–6 weeks of design, 4–6 weeks of permits, then 8–14 weeks of construction. Total: 4–7 months from first conversation to final walkthrough. Historic-zone properties run longer.
