For a single permit lookup or anything requiring official confirmation — issuance, occupancy sign-off, final inspection — the Sacramento Citizen Access is the source of record. Go directly to the City of Sacramento portal for those.
For ongoing monitoring across multiple Sacramento 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 Sacramento jobs across different systems or stages where checking each official source daily is impractical.
Both tools draw from the same underlying permit record — the Sacramento Citizen Access is always the system of record; SignedOff is a monitoring layer on top of it.
