Your lease or rental agreement should spell out your landlord's key rent rules, including:
State laws in Missouri cover several of these rent-related issues, including the amount of notice a landlord must provide to increase rent under a month-to-month tenancy, and how much time a tenant has to pay rent or move before a landlord can file for eviction.
Rent is legally due on the date specified in your lease or rental agreement (usually the first of the month). If you don't pay rent when it is due, the landlord may begin charging you a late fee. Missouri state law does not cover late rent fees. If your lease or rental agreement does not say anything about late fees, your landlord may not impose one, no matter how reasonable it is.
Missouri does not have a state statute on the amount of notice the landlord must provide tenants in order to increase the rent or change other terms of a month-to-month rental agreement. Unless your rental agreement specifies otherwise, the landlord must typically provide the same amount of notice to change the rent or another term of the tenancy as state law requires the landlord to provide when ending the tenancy—in this case, one month. Keep in mind that if you have a long-term lease, the landlord may not increase the rent until the lease ends and a new tenancy begins—unless the lease itself provides for an increase.
Missouri landlords may not raise the rent in a discriminatory manner—for example, only for members of a certain race.
States set specific rules and procedures for ending a tenancy when a tenant has not paid the rent. Missouri landlords must give tenants at least five days in which to pay the rent or move. If the tenant does neither, the landlord can file for eviction.
