With its mix of historic neighborhoods, spacious lots, and a relatively lower cost of living compared to coastal cities, Riverside presents unique opportunities for ADU development.

The cost of building an ADU in Riverside typically ranges from $100,000 to $300,000 depending on size, type, and finishes. Given Riverside's growing rental market and proximity to UC Riverside and major employment centers, a well-built ADU can generate significant rental income, making it a smart long-term investment for homeowners throughout the city.
