Why a garage conversion is the smart first ADU
Many Menifee homes were built with oversized two- and three-car garages that rarely hold cars. Those garages convert beautifully into 400–600 sq ft studio or one-bedroom ADUs. Because the foundation, slab, and exterior walls already exist, a conversion skips the most expensive parts of new construction — which is why it is consistently the lowest-cost and quickest route to a legal, rentable unit.
Done right, a converted garage doesn't look like a converted garage. We replace the garage door with proper windows and an entry, insulate to California Title 24, and finish the interior to the same standard as any new ADU — kitchenette or full kitchen, bathroom, and dedicated HVAC.
Cost and timeline in Menifee
A garage conversion in Menifee typically runs $60,000 to $120,000 and completes in 3 to 5 months — often saving $40K–$80K versus a comparable new detached build. Final cost depends on whether your garage needs new electrical service, plumbing routing, and how the existing slab and roofline are configured. We confirm all of this up front and put it in a fixed written scope.
Permitting and parking
We handle the full permit submittal through City of Menifee Building & Safety, including the Title 24 energy compliance and structural details inspectors look for. Current California ADU law generally removes the requirement to replace parking lost when you convert a garage, which is part of what makes conversions so practical — but we confirm the specifics for your parcel during design.
Built by one licensed crew
As a licensed general contractor (CSLB #1009685) self-performing the work, we manage demolition, framing, MEP, and finishes in-house, so your conversion stays on one schedule with one point of accountability from start to final inspection.
Frequently asked questions
Do I have to replace my garage parking if I convert it?
Under current California ADU law, homeowners generally are not required to replace the parking spaces lost when converting a garage to an ADU. We verify the rules that apply to your specific Menifee parcel during design.
How much does a garage conversion ADU cost in Menifee?
Most Menifee garage conversions run $60,000 to $120,000, depending on the garage's existing condition and what electrical, plumbing, and structural work is needed. You get a fixed written price before work begins.
Is a converted garage a 'real' permitted ADU?
Yes. We build conversions to full code with City of Menifee permits and inspections — proper insulation, egress, Title 24 energy compliance, and finished kitchen and bath — so it is a legal, rentable dwelling, not an unpermitted room.
How long does a garage conversion take?
Typically 3 to 5 months in Menifee, including permitting and construction — faster than a ground-up detached ADU because the foundation and shell already exist.
