Legal Question in Landlord & Tenant Law in Missouri

Re: Laws on landlords entering without notice and invertation

Unfortunately there is no statute on this issue. The common law doctrine is called the "covenant of quiet enjoyment." Under the covenant, when a landlord leases property to another, he covenants that the lessee will be able to enjoy the property without his or her peace being disturbed by the landlord. If a landlord breaches the covenant, there is an action for damages.

Of course, there may also be a a provision in your written lease that provides that the landlord may not enter without notice. Generally entry without notice (unless there is an emergency, like smoke coming out of your apartment) is considered to be a breach of the covenant if it happens more than once.

Your best bet would be to notify your landlord that you want 24 hours notice before entry, and tell him that entry in the absence of notice is a violation of the covenant of quiet enjoyment, and that you will pursue a legal remedy if this continues.

Good luck
