Source: LADBS, Building and Safety - Building Permits Issued from 2020 to Present (N), data.lacity.org, read 18 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.
Building permits the City of Los Angeles Department of Building and Safety (LADBS) issues inside the city limits only. Other cities in Los Angeles County (Long Beach, Pasadena, Santa Monica, Glendale and the rest) and unincorporated county land run their own permit offices and are not in this file. Electrical, plumbing and mechanical permits are kept by LADBS in separate files and are not counted here, so those trades show only when a building permit names them.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
