You cannot raise the rent if you and the tenant have agreed, usually in a written lease, on a certain amount. Usually, you and the tenant will agree on a certain amount for a specific period of time. Once that time period ends, you can raise your rent with 30 (thirty) days written notice. If you and the tenant never agreed on a specific period of time, you can usually raise the rent with 30 (thirty) days written notice.
You may decide to give more notice, but only 20 days is required under the law.
