Stylish, Compliant ADUs Built With Care

An ADU, also known as a secondary dwelling unit or in-law suite, is a self-contained living space located on the same property as a primary residence. These units have become increasingly popular in California due to rising housing costs, changing zoning laws, and the need for more affordable and versatile living options.



At AV Builders Group, we understand how to navigate the specific building codes, local ordinances, and design preferences to ensure your ADU is both beautiful and compliant. Our team works with you from start to finish—from concept and permitting to construction and final inspection—to deliver a quality structure that meets your needs and budget.

Benefits of Adding an ADU to Your Property

Homeowners across Santa Clara & Monterey Counties, CA, are discovering the many advantages of adding an ADU, including:


  • Increased property value
  • Additional rental income
  • Flexible living arrangements (ideal for aging parents, adult children, or guests)
  • Private home offices or studios
  • More efficient use of existing property space
  • Sustainable building options with modern energy-efficient features


An ADU gives you more than just square footage—it adds lifestyle flexibility and long-term financial benefits.

Attached, Detached & Backyard ADU Solutions

ADUs come in a variety of layouts and configurations, and AV Builders Group can help you determine which one is best for your property:

  • Detached ADUs: Standalone units built in the backyard or side of your property. These are ideal for creating full privacy between the main home and the ADU.

  • Attached ADUs: These units are physically connected to the main home (often built as an extension or above the garage) and share some infrastructure while maintaining private entrances.
