LA County Planning started with the founding of the Los Angeles County Regional Planning Commission in 1923. We provided staff advice and help to the Commission. In 1974, we became an independent County Department.
LA County Planning is the planning department for all areas outside a city in LA County. We provide all major planning functions for these unincorporated areas. We help write long range plans, review development projects, and respond to zoning complaints.
In 2023, we are celebrating 100 years of the Los Angeles County Regional Planning Commission. Visit RPC History to learn more.
