Building, electrical, plumbing, mechanical, solar, re-roof, fence, pool and fire-sprinkler permits the City of Corona Building Division issues inside city limits. Unincorporated neighbors such as Temescal Valley, El Cerrito, Home Gardens and Coronita get their permits from Riverside County and are not in this file (they are on the Riverside County pages). Public-works encroachment and utility permits and planning or fire-prevention reviews are not counted.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
