The City of Riverside follows the statewide ADU rules — impact fees waived under 750 sq ft and a 60-day approval clock — with city permit fees typically $3,000–$6,000.
Riverside ADUs rent for $1,500–$1,900/month, with steady demand from UCR, RCC, and the medical center.
The Wood Streets, Magnolia Center, and Arlington have the deep lots and detached garages that make ADUs easy; Canyon Crest and Mission Grove favor detached units on larger parcels.
