I have no license to enforce the law so I can't go in and break up the party. And, I am not allowed to evict a tenant for having a party. Basically, with a law like this I'm screwed (literally and figuratively). I would sell my rental properties.
It's bad enough with the Landlord-Tanant Affairs Nazis always coming down on landlords for things such as grease smoking when it's on a stove burner. It happened to me... the idiot tenant spilled grease on the stove burner (electric stove) and the Montgomery County Landlord-Tenant Affairs Nazis told me that I had a defective stove!!!
Is it possible in MD to have your rental/lease agreements prohibit "disturbances" or other criminal activity? I think you could lawfully evict or refuse to renew the lease under a lease violation. Or does it go beyond that?
