Residential building permit (BRES)
New single-family dwellings, additions, and alterations in unincorporated Riverside County. Filed as a Building and Safety Residential (BRES) permit and routed through full plan check unless it qualifies for a simpler over-the-counter path.
Timeline: County asks applicants to allow three business days to process issuance once clearances and fees are complete; major additions or new dwellings require full plan check and commonly run several weeks to a few months depending on backlog.
