can landlord raise rent without notice
In a month-to-month tenancy, your landlord may not increase rent during the first year of your tenancy. After that, your landlord may increase the rent by giving you at least 90 days written notice of the rent increase. The written notice must specify the amount of the rent increase, the amount of the new rent, and the date it goes into effect. A rent increase may begin any time during a month. The rent for a month during which the rent increase takes effect would be prorated.
