What Is an ADU?
An Accessory Dwelling Unit is a secondary residential structure located on the same property as a primary home. ADUs can be attached, detached, or converted from existing spaces like garages or basements.
Common ADU types include:
- Detached backyard homes
- Garage conversions
- Above-garage apartments
- Attached room additions
- Basement conversions
- Junior ADUs (JADUs)
California has simplified ADU regulations in recent years, making it easier for homeowners to build legal and functional secondary units.
Why Homeowners in Corona Are Building ADUs
Corona has become one of the most attractive locations for ADU development in Southern California. The city offers growing neighborhoods, rising property values, and increasing demand for flexible housing.
1. Generate Rental Income
Many homeowners use ADUs as long-term rental units to create passive monthly income. With California rental demand remaining high, a well-designed ADU can significantly increase property cash flow.
2. Increase Property Value
An ADU adds usable square footage and functionality to your property, increasing resale value and market appeal.
3. Multi-Generational Living
Families often build ADUs for aging parents, adult children, or extended family members who want privacy while staying close together.
4. Home Office or Studio Space
Remote work has increased the need for quiet and productive workspaces. ADUs provide separate offices, creative studios, or business spaces without sacrificing home comfort.
5. Flexible Lifestyle Benefits
ADUs can serve multiple purposes over time. A guest house today could become a rental unit or family suite tomorrow.
