Expand Your Space with an ADU or Garage Conversion in San Diego
Building an accessory dwelling unit (ADU) or converting an underused garage into a functional living area is a great way to accommodate aging in-laws, house adult children, and generate passive rental income in your San Diego home.
Optimizing your existing space requires an experienced ADU and garage conversion contractor who can turn your vision into reality.
Crafting Your Dream ADU
What Are Accessory Dwelling Units (ADUs)?
Accessory Dwelling Units (ADUs) are self-contained living spaces built on the same lot as an existing single-family home in San Diego. Often called granny flats, in-law suites, or backyard cottages, ADUs include their own kitchen or kitchenette, bedroom(s), bathroom, and living area—making them completely independent from the main house.
ADUs can be attached to the primary residence, converted from existing space (like a garage), or built as detached standalone units. With new California laws making ADUs faster and easier to build, homeowners are using them to create private living space for family, add long-term rental income, or increase property value.
ADUs expand usable square footage while offering flexibility: multigenerational housing, guest quarters, or a high-demand rental opportunity in San Diego’s tight housing market.

ADUs can be attached to the main home or built as detached standalone structures.
