Accessory Dwelling Units (ADU)

Experienced ADU Builders in the Bay Area

Building an ADU is more complex than adding a room to your home. RSP Group, located in Fairfax, CA, specializes in designing and planning ADU modular homes for Bay Area families. ADUs are additional housing units on a single-family lot that require all the primary house's utilities. Essential elements for an ADU project include:

• Landscaping and site work
• Structural foundation work
• Framing and finishes
