My Tenant owns a roofing company and is using the house as the business address

Hi Bigger pockets.

This is my first post, so please forgive my ignorance.  I own a rental property (4 bedroom house)  and the Tenant is using the property as his business address for his construction business.  We told the property manager about this 6 months ago and  she addressed it with the Tenant.  I checked yesterday and the Tenant is still using the rental as the business address.  Can you please advise me on what to do next or what constructive steps I can take to resolve this.  I live in California and I'm trying to be very careful to do the appropriate thing.  I'm not very knowledgeable and would appreciate your input.  Thank  you so much in advance.
