Introduction
Are you thinking about adding an Accessory Dwelling Unit (ADU) to your Silicon Valley property? With housing demand at an all-time high and local zoning regulations evolving, ADUs—sometimes called backyard cottages, granny flats, or in-law suites—are more popular than ever. Whether you’re seeking extra space for family, rental income, or a home office, here’s what every Silicon Valley homeowner should know about building an ADU.
What Is an ADU? (ADU Meaning)
An ADU (Accessory Dwelling Unit) is a self-contained living space built on the same lot as a primary home. ADUs can be detached backyard ADUs, attached units, garage conversions, or even basement apartments. In California, ADUs are a flexible solution for adding value and functionality to your property.
Spacious ADU living space with tall ceilings, multiple windows, minimalist furniture, and a bright, airy layout ideal for Silicon Valley homeowners.
Why Build an ADU in Silicon Valley?
1. Increase Property Value:
Modern ADUs are a major selling point, especially in competitive Bay Area neighborhoods.
2. Generate Rental Income:

3. Support Multigenerational Living:
ADUs (or granny flats) create independent living spaces for family, guests, or caregivers.
4. Flexible Use:
From home offices to guest suites, ADUs adapt to your changing needs.
