Accessory Dwelling Units (ADUs): Smart, Stylish, and Sustainable Living Spaces

In an era where housing flexibility is more important than ever, Accessory Dwelling Units (ADUs) are transforming how families live, grow, and adapt. At RCS Pro Build, we specialize in accessory dwelling unit construction that reflects your goals—whether you’re looking for a creative rental opportunity, a comfortable home for extended family, or simply more space for your lifestyle.

From cozy backyard cottages to converted garages, ADU homes offer functionality, beauty, and independence—all within your property line.

What Is an ADU?

An additional dwelling unit—also known as an ADU—is a self-contained residential unit located on the same lot as a primary home. These can come in several forms:

  • Detached ADUs: Independent structures built separately in your backyard.
  • Attached ADUs: Connected to the main house but with their own entrance.
  • Garage Conversions: Converting garage to ADU is a popular option for turning underutilized space into livable square footage.
  • Basement or Upper-Level Conversions: Transforming an existing floor into a comfortable adu unit.

No matter the layout, these dwellings are designed with private living in mind—complete with kitchenettes, bathrooms, and independent utilities.
