Reported Pets at my No Pets Allowed SFH

[JJ Jameson]

My handyman reported my renters have 3 dogs inside my SFH rental. The lease clearly states no animals or pets allowed without prior written consent from me. There is no penalty dollar amount specified for violation nor pet deposit or pet rent amounts outlined since it is a No Pet/Animal Policy.

Tenants are on a 12 month lease and have not been late so far.  Since I have not seen the animals first hand and have no physical evidence other than my handyman’s report - what should my course of action be?  If I schedule a visit I’m sure they will remove the dogs.  Should I just drop by and surprise them?  Do I need to set eyes on the animals myself before taking action?

I don’t want to start eviction without speaking to them first and need to know my rights in this situation.
