Who Qualifies for California ADU Grant? Comprehensive Guide

Accessory Dwelling Units (ADUs) have gained significant popularity in California as a solution to the housing crisis. These small, self-contained living spaces provide affordable housing options while allowing homeowners to generate additional income. 

To encourage the development of ADUs, the California state government has introduced ADU grants. 

In this article, we’ll explore who qualifies for the California ADU grant and provide a comprehensive guide that leaves no stone unturned, helping you understand the eligibility criteria and application process with confidence.

What is an Accessory Dwelling Unit (ADU)?

An Accessory Dwelling Unit, or ADU, is a secondary living space built on the same property as a single-family home. 

ADUs can be:

Detached: Standalone structures separate from the main house

Attached: Connected to the main house, such as a converted garage or addition

Junior ADUs: Created within the existing space of the main house, like a converted bedroom

Benefits of building an ADU include:

  • Providing affordable housing for family members or renters
  • Generating additional income through rent
  • Increasing property value
  • Promoting sustainable land use and urban infill development
