Maryland Rent Increase Laws (2026)

In Maryland, a landlord must give 60 days for month-to-month (Montgomery County: 90 days) before increasing rent on a month-to-month tenancy. The notice must be in writing and clearly state the new rent amount and the effective date.

The notice period runs from the date the tenant receives the notice — not the date the landlord drops it in the mail. Best practice: deliver in person or via certified mail, and keep a signed copy or delivery confirmation.

Even though there's no statewide cap, individual Maryland cities and counties may have local ordinances limiting how much rent can rise in a year. Always check your municipality before issuing an increase notice — local caps trump general state law.

For fixed-term leases (a year, two years, etc.), rent generally cannot be increased during the term unless the lease itself contains an escalation clause. The lease is a contract — both sides locked in the rent for the term.

Month-to-month tenancies, by contrast, can be increased at any time with the proper 60 days for month-to-month (Montgomery County: 90 days) notice. Many landlords use month-to-month renewals specifically to keep rent flexible.

Even where Maryland allows unlimited rent increases, federal and state law prohibits raising rent in retaliation for protected tenant activity. A rent increase issued shortly after a tenant complains about habitability, requests a repair, contacts code enforcement, or joins a tenant organization can be challenged as retaliatory.

Similarly, the Fair Housing Act prohibits rent increases that target tenants based on race, color, national origin, religion, sex, familial status, or disability. State law often adds additional protected classes (sexual orientation, source of income, etc.).

A rent increase notice in any state should include:

• Tenant name(s) and rental address
• Current rent amount
• New rent amount
• Effective date (must be at least the required notice period after delivery)
• Date the notice is delivered
• Landlord signature
• Method of delivery (in-person, certified mail, email if lease permits)

When facing an increase, tenants generally have three options: accept the new rent, negotiate, or give notice and move out within the notice window. Many landlords will negotiate a smaller increase rather than face a vacancy and turnover costs.

If the increase appears retaliatory, discriminatory, or above a local rent control cap, the tenant can challenge it — typically by refusing to pay the increase, documenting the basis for the challenge, and being prepared to defend against an eviction filing.
