No, it is not. Calls to 911 are not private (think of the various 911 tapes that have been released by the media in sensational cases, for example). The Sheriff was not required to honor your request to call before investigating your complaint. Moreover, you called an emergency number for something that was not an emergency nor even a crime. Might have violated building codes rules, but the Sheriff doesn’t enforce those.
Assuming that your call here is covered by this statute, it gives you a remedy to sue to the landlord for $250 or the actual damages you suffer, whichever is greater, plus attorney’s fees. It might also give you a defense to the eviction if the landlord uses your call for police assistance as the reason for eviction. But if the landlord has other grounds for eviction, that statute won’t help you with the eviction.
I too suspect there is much more to this story than you have told us here. Few landlords are going to evict a tenant because the landlord sees a sheriff in the driveway talking with the tenant without something more going on.
