LADBS requires a separate Certificate of Occupancy inspection for any change of use, even when the scope of work is already covered under an active building permit — meaning a single project can involve parallel inspection tracks that both need to clear before the space can be legally occupied.
Los Angeles has a dedicated mandatory soft-story retrofit program with its own fast-track queue, but applications require an engineer-stamped retrofit letter submitted upfront — starting the process without that letter in hand is one of the most common causes of rejection.
Projects inside Los Angeles specific plan areas or historic preservation overlay zones (HPOZ) require additional zoning clearance and design review before LADBS will issue a building permit, which can add weeks or months on top of normal plan check timelines.
The LADBS is the authoritative source for single-permit lookups and the official status of record in City of Los Angeles, reachable at https://www.ladbsservices2.lacity.org/OnlineServices/. Third-party permit monitoring services such as SignedOff poll LADBS on a recurring schedule to detect status changes, scheduled inspections, and expiration deadlines for Los Angeles permits. This approach is most useful for contractors, architects, and project managers tracking multiple active Los Angeles permits across jobs, where logging into the portal manually for each permit becomes impractical.
Permits in Los Angeles flow through LADBS Online Services, the same portal system used by several other jurisdictions SignedOff covers. See the LADBS Online Services adapter page for technical details on how the system works and every jurisdiction it currently supports.
For a single permit lookup or anything requiring official confirmation — issuance, occupancy sign-off, final inspection — the LADBS is the source of record. Go directly to the City of Los Angeles portal for those.
For ongoing monitoring across multiple Los Angeles permits, a third-party service such as SignedOff reduces manual portal logins and surfaces status changes by email. The typical use case is a contractor, architect, or project manager with several active Los Angeles jobs at different stages — plan check, inspection, close-out — where logging into the portal daily for each one isn't practical.
Both tools draw from the same underlying permit record — the LADBS is always the system of record; SignedOff is a monitoring layer on top of it.
LADBS Express Permits clear same- to next-day, while Regular Plan Check for residential and commercial projects typically runs 4-12 weeks depending on complexity. ADUs are capped at 60 days under California SB-13, and residential solar PV typically issues same- to next-day via Express Permit or SolarAPP+. SignedOff monitors your Los Angeles permit and notifies you the moment status changes.
