20+ years. 390+ LA remodels. Typical garage conversion: 8–14 weeks (JADU path with kitchen + bath adds 4–8 weeks).
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.
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.

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.
Simple conversions (office, studio without plumbing) run 4–8 weeks. Full JADU conversions with kitchen and bath take 3–5 months including permits.
Yes — converted livable square footage increases appraised value, especially when permitted as ADU. Unpermitted conversions can actually hurt resale, so do this right.
The finished-space result is similar (livable square footage, permitted), but the process differs. Garage conversion = adapting an existing structure (foundation + walls + roof already in place). Detached ADU = ground-up new build. Conversion is faster + cheaper because you're not pouring foundation or framing walls from scratch — but you're bound by the garage's existing footprint + ceiling height.
Mixed. A permitted JADU adds appraisable livable square footage, which usually increases home value more than the parking-space value it removed. But some LA neighborhoods (especially those with tight street parking) do see modest resale discounts from buyers who want a garage. Onn walks you through the trade in your specific neighborhood before you commit.
