Full Breakdown
Before raising rent, a Rockville landlord must give the tenant 90 days' written notice stating the old rent, the new rent, the effective date, the percentage increase, the City's recommended guideline percentage, and any rent-subsidy information the City has furnished. Landlords must also send that same notice to the Director of Housing and Community Development, except landlords of single dwelling units, who are excused from the Director-copy requirement. Leases themselves must independently contain a clause requiring 90 days' written notice of any rent increase, so the notice duty is baked into every rental agreement, not just imposed as a standalone rule.
Violations & Fines
Raising rent without 90 days' advance written notice, or omitting required details like the old rent, new rent, effective date and percentage, violates the notice requirement enforceable before the Commission on Landlord-Tenant Affairs.
