For a single permit lookup or anything requiring official confirmation — issuance, occupancy sign-off, final inspection — the San Bernardino County Citizen Access is the source of record. Go directly to the San Bernardino County portal for those.
For ongoing monitoring across multiple San Bernardino County permits, a third-party service such as SignedOff reduces manual lookups and surfaces published status changes by email. The typical use case is a contractor, architect, or project manager with several active San Bernardino County jobs across different systems or stages where checking each official source daily is impractical.
Both tools draw from the same underlying permit record — the San Bernardino County Citizen Access is always the system of record; SignedOff is a monitoring layer on top of it.
