ADU Contractors in San Diego
Building an Accessory Dwelling Unit (ADU) is one of the smartest investments a San Diego homeowner can make. Whether you want a rental unit for passive income, an in-law suite for family, or a home office detached from the main house, Subworkit Contracting handles the entire process — design, engineering, permits, and construction — as your single-source ADU contractor.
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.
