As I operate extensively in both Los Angeles City and County, I can tell you that I am almost certain that these citations are coming from the Los Angeles City Department of Transportation, as their officers have been very active lately. Los Angeles County generally doesn't bother to check on the status of the vehicles operating within their jurisdiction for compliance with Los Angeles County mandates. You don't even need certification through LA County DHS EMS Agency to operate within Los Angeles County as long as you confine yourself to LA City limits. However, I will admit that I am assuming that this is a City problem vs. a County problem based on the current climate in Los Angeles City. I don't know for sure whether this is a city or county issue. All I meant was that should a company loose its ability to operate within the City of Los Angeles, that company could still have a chance of staying operational by serving unicorporated cities of Los Angeles County wherein Los Angeles City holds no jurisdiction (e.g., Burbank, Glendale, Pasadena, Santa Clarita, Culver City, Santa Monica, Beverly Hills, West Hollywood, etc.). LA is not LA is not LA. You have Reference Numbers in the EMS Agency Prehospital Care Policy Manual that conflict with Los Angeles County Municipal Code 7.16 which conflict with Los Angeles City Ordinance and yet all of these laws apply to "LA".
I think you misunderstood me . Yes this is 99% likely coming from LA LADOT. You do not need county permit LA County to operate in WH, BH, SM, Burbank, Glendale as all of those city are incorporated. LA county only hold jurisdiction in city that is unincorporated. To operate in WH for example is simple business license one sheet and $25 and you're good to go. SM is similar but you need to get pd permit(owner(s) need to have background done through pd). Burbank got own rules, can get approval in couple of weeks. Glendale is a nightmare, worse then even LA.
