Most garage conversions in the Las Vegas area cost between $20,000 and $60,000, depending on size, finish level, and whether you’re adding a bathroom or kitchenette. A basic conversion (flooring, drywall, insulation, HVAC) sits at the lower end, while a full guest suite or rental-ready unit with plumbing and a kitchen pushes toward the higher end.
Garage Conversion Cost Breakdown
• Basic living space conversion ($20,000–$35,000): Insulation, drywall, flooring, electrical, and HVAC. Good for a home office, gym, or den.
• Bedroom or guest suite ($35,000–$50,000): Adds a closet, proper egress window, and sometimes a half bath.
• Full guest house conversion ($50,000–$60,000+): Full bathroom, kitchenette or kitchen, and finishes on par with the rest of the home. This is what most homeowners mean when they ask a garage conversion contractor for a true guest house.
What Drives the Price Up or Down
Plumbing — adding a bathroom or kitchen means running new plumbing lines, which is one of the biggest cost jumps in any garage conversion.
Finish level — a luxury garage builder using higher-end flooring, cabinetry, and fixtures will naturally run above a basic remodel.
Permitting and code upgrades — garage doors need to be removed and framed as a real wall, and the space often needs new insulation and electrical to meet residential code.
This varies by city, so a local garage conversion contractor will know what Las Vegas, Henderson, North Las Vegas, or Boulder City inspectors require.
Garage size — a standard 2-car garage (around 400 sq ft) costs less to convert than a 3-car garage.
