Fire Insurance Non-Renewed (Safeco) in CA- any chance to fight with change of broker?

[Tricia O'Brien]

I found out on July 15 that my landlord policy in California on my single family rental home is being non-renewed and the last day of coverage is Aug 1.  The stated reason is that my independent agent is being cancelled by Safeco and will no longer be a Safeco agent. 

I'm going to try to get Safeco to waive their new policy of not allowing any change of broker requests to go through after July 1, 2024 based on the fact that I never received their notice of Non-Renewal (dated May 4, 2024 ) in the mail and only got a copy of  it by email from my agent's office on July 17.  

I've been told that the law requires insurance companies to give  90 days written notice of non-renewal, but if I never received it by US mail from them, do I have a good case that they are out of compliance with that law and need to allow me to switch agents and renew?

How should I approach negotiating with Safeco? 

Does anyone know if the 90 day notice requirement is a California law or federal law? 

Since I've been told the insurance market is really tough right now in California with most of the big companies (Nationwide, Allstate, State Farm)  not writing new policies to new customers, I'm trying to do a change of broker to a different Safeco agent. I found one is Sonora CA who is willing to do this, but I have to negotiate with Safeco to get them to allow this exception to the July 1 deadline; however,  I would not have needed the exception if I'd gotten the Non-renewal notice in time.

Thanks in advance for your suggestions ! :)
