Maryland Rent Increase & Notice Rules: How Much Warning a Landlord Must Give

In Maryland, there is no statewide rent control, so for most tenants a landlord can raise the rent as much as they want once your lease allows it. What the landlord cannot do is raise it without warning: to increase rent on a month-to-month tenancy, the landlord generally must end the old terms and offer new ones, which under Maryland's landlord-tenant statute usually means at least one full month's written notice (and longer in some counties and cities). Disputes over rent and possession are heard in the District Court of Maryland, the trial court that handles failure-to-pay-rent and holdover cases statewide.

Raising rent on a month-to-month tenancy

Maryland does not have a single statute that says "a rent increase needs X days' notice" in plain numbers. Instead, a rent increase on a periodic (month-to-month) tenancy is treated as a change to the terms of the tenancy, which the landlord cannot impose mid-period. To change the rent, the landlord effectively has to give the same notice required to end the month-to-month arrangement and offer to continue at the new rate.

• Statewide, that notice is commonly one full calendar month before the increase takes effect, given in writing.
• You can decline the new rent by giving your own notice and moving out, or you can accept it by staying and paying.
• Several Maryland jurisdictions require more notice than the state baseline, so always check your county or city rule before assuming 30 days is enough.

Because the exact number of days and the way notice must be delivered can change, confirm the current requirement in Maryland Real Property Article (the state's landlord-tenant statute) and your local code before relying on it.

Ending a month-to-month tenancy

The notice to end a month-to-month tenancy in Maryland generally runs both directions:

• Landlord ending the tenancy: typically at least one month's written notice under the statewide default, longer where local law requires it.
• Tenant ending the tenancy: a tenant who wants to move out of a month-to-month also generally owes the landlord one month's written notice, timed to the rental period, so you are not stuck owing an extra month's rent.

If a tenant stays past the notice period (a "tenant holding over"), the landlord's remedy is to file in the District Court of Maryland rather than to change the locks or remove belongings, which is illegal self-help eviction in Maryland.

Fixed-term leases: rent is locked in

If you signed a lease for a set term, such as one year, the landlord generally cannot raise the rent in the middle of that term unless the lease itself contains a clause allowing it. The agreed rent holds until the lease ends.

• At renewal time, the landlord can propose a higher rent for the next term.
• Read any "escalation" or "additional rent" clauses carefully, since those are the usual exceptions.
• Some Maryland jurisdictions also require advance notice before a fixed-term lease is non-renewed or its rent raised at renewal.

Statewide rent control vs. local exceptions

Maryland has no statewide rent control or rent stabilization, but unlike some states it has not banned local governments from adopting their own. That has produced a patchwork:

• Montgomery County adopted rent stabilization that caps annual increases for covered units, tied to a measure of inflation, and imposes longer notice rules. Confirm the current cap and covered properties with the county.
• Takoma Park has long-standing rent stabilization limiting yearly increases.
• Prince George's County has used temporary rent caps. Check whether any cap is currently in effect.
• Baltimore City and other localities have their own notice and registration rules.

Because these local programs are added on top of state law, the rule that applies to you depends on exactly where the unit sits. A property just over a county line can be governed by completely different limits.

When to get help

If your landlord raised the rent without proper notice, tried to raise it mid-lease, or is threatening eviction, it is worth talking to a Maryland tenant attorney or your local legal aid office, especially in a county with rent stabilization where the math and notice rules are detailed. Many Maryland legal aid programs help renters for free, and the District Court has self-help resources for both sides.
