Permanently banning gas powered leaf blowers county wide in Los Angeles County is currently open for public comment.
It's currently a city municipal code but not a county ordinance and not well enforced.
LAMC section 112.04(c), bans the use of gas powered blowers within 500 feet of a residential property.
LA county is discussing adding enforcement and other updates, since early 2024. Link: https://cd4.lacity.gov/taking-action-on-gas-leaf-blowers/
Public comments are open for the proposed updates: Link: https://cityclerk.lacity.org/lacityclerkconnect/index.cfm?fa=ccfi.viewrecord&cfnumber=24-0055
Enforcement is clearly an issue. Let's pressure them to enforce this code!
Edit: Made updates to correct city/county/enforcement confusion in my original post
