Tenant forfeits their security deposit if there is any evidence of cannabis use on the premises.”. Smoking is defined as the inhaling, exhaling, or possession of any lighted cigarette, cigar, pipe, or other similar apparatus containing tobacco, as well as any other similar lighted products. Tenant is not permitted to smoke on the described premises. Where there may be a problem, there is usually a solution and this is it. Use this Smoke-Free Property Addendum to attach to your leases to make your precious investment safe from the physical hazards of smoke. Unlike a lease amendment, which is a change in the contract itself, a lease addendum is an additional document that is added to the existing lease agreement. For example, in the residential lease context, pet ownership, roommate expectations, crime free agreements, and lawn care policies may all be controlled by addenda (if they are not already controlled by the lease itself).
