Garage Conversions in San Diego
A garage conversion is the most affordable way to add legal, permitted living space to a San Diego home. Whether you're converting to a full ADU for rental income, an in-law suite for family, or a home office and workout room, Subworkit Contracting is a licensed general contractor (CA #945572) that handles the entire process. We design, permit, insulate, run plumbing and electrical, frame interior walls, install windows and doors, finish drywall, and complete final finishes — typically for $75,000–$130,000 depending on ADU features.
As San Diego's largest city with over 1.4 million residents, we serve every neighborhood — from the coastal communities of Pacific Beach and La Jolla to inland areas like Mira Mesa, Scripps Ranch, and Rancho Bernardo.
San Diego's Mediterranean climate means year-round construction is possible, but UV exposure takes a toll on roofs, paint, and outdoor structures. Many homes in older neighborhoods like North Park and Hillcrest were built in the 1920s–1950s and need regular maintenance and updates to meet current building codes.
