What Is an ADU?
An Accessory Dwelling Unit, commonly known as an ADU, is a secondary residential unit built on the same property as an existing home. These units can be attached to the main house, converted from an existing structure, or built as a standalone unit in the backyard.
Popular ADU types include:
- Detached ADUs
- Attached ADUs
- Garage Conversion ADUs
- Basement Conversion ADUs
- Junior ADUs (JADUs)
A modern backyard adu provides homeowners with additional living space without requiring the purchase of another property.
Why ADUs Are Booming in California
California has embraced ADU development as a solution to housing shortages and rising real estate costs. State regulations have become increasingly ADU-friendly, making it easier for homeowners to secure permits and complete projects.
Key reasons homeowners are investing in ADUs include:
1. Additional Rental Income
A well-designed ADU can generate substantial monthly rental income. Many homeowners use rental earnings to offset mortgage payments and increase financial security.

3. Flexible Living Arrangements
ADUs are perfect for:
- Aging parents

4. Cost-Effective Housing
Compared to purchasing a new home, building an ADU can be a more affordable way to gain additional living space.
