City of Los Angeles — not Los Angeles County
City of Los Angeles Contractor & Permit Intelligence
Official LADBS certificates of occupancy, a stale PCIS contractor-license extract, and current 2020+ issued-permit activity. This is City of Los Angeles evidence. It is not Los Angeles County permit data. Not a ranking or Trust Score.

Which sources include exact CSLB numbers?
- Current weekly CofO: 68,813 rows with a source-native CSLB number, 2,507 distinct IDs in the acquired spine,10,279 exact IDs outside the partial extract.
- Stale PCIS (2023-05-22): 207,951 source-native CSLB rows,3,063 acquired-spine licenses, 15,069 outside the partial extract.
- Current 2020+ issued-permit extract (409,619 rows) has no contractor/license fields. It is not joined to PCIS by address.
Union of exact acquired-spine licenses: 3,708. Exact local license IDs outside the partial state spine: 16,704. Those identifiers are not unlicensed. CofO and PCIS rows are reported separately (12,505 + 28,974) and are not double-counted as one permit universe.

Exact CSLB work-activity lookup
This lookup uses source-native CSLB numbers only. Name-only or high-confidence business-registry matches are not work history. Permit activity is not quality.
Inspections
11,691,152 inspection events exist on the official source. This page does not ship an 11.7 million-row runtime file. Where a permit number is present, inspections may be described as inspection events associated with that permit — not “contractor passed N inspections.”
What this does not tell us about Los Angeles County
- Unincorporated Los Angeles County and other cities are not in these files.
- Current weekly permits without a license field are not contractor-attributed.
- Permit activity is not quality, revenue, or completeness of work.
