.✅ Thirdly, in regard to objectionable tenancy and nuisance caused by disruptive tenants, you will need to document these violations with undeniable evidence.Because police reports are not usually able to be procured due to disturbances like drug trafficking or domestic violence, you’ll need to take matters into your own hands on producing that documentation.I recommend getting security cameras installed in all common areas and outside your properties.I’ve used SimpliSafe security cameras but you’ll need to install WiFi service at your properties so that you can maintain recordings in the event of violations and add to your lease that any tampering with said cameras constitutes a lease violation as well.This is still developing and once we get further clarity, we will host a round table with legal experts on how to best protect our properties and residents.
