Maryland Rent Increase Laws for Landlords (2026)

In short: Maryland requires 90 days' notice before a rent increase takes effect, and there is no cap on the amount.

What Maryland law requires

Maryland is one of the 19 US jurisdictions with a statute that speaks directly to raising rent. It requires 90 days' notice before an increase takes effect, in writing.

The notice is not one number. 90 days for a term over one month, including month-to-month; 60 days for a term of one week to one month; 21 days for a shorter term with no written lease.

How much can you raise it in Maryland?

There is no statutory ceiling. No statewide cap, though two counties have their own. Maryland's statewide notice is among the longest in the country.

Only four US jurisdictions cap the size of an increase - California, Oregon, Washington and the District of Columbia. Maryland is not one of them, so the amount is a business decision, not a legal one. The usual constraint is practical: a tenant who leaves over an increase costs you a turnover, and a turnover costs more than the increase was worth.

Local rules override this. Montgomery County and Prince George's County both cap most annual increases under their own rent stabilization laws, on top of the statewide notice. Check the current county formula before serving notice.

Can you raise rent mid-lease in Maryland?

No. A fixed-term lease fixes the rent for the term. An increase takes effect at renewal, or on a month-to-month tenancy after proper notice. The exception is a lease that contains its own escalation clause agreed at signing.

Serving the notice so it holds up

Most rent increases that fall apart fall apart on the date, not the amount: the notice went out too late, or nobody can prove when it went out. Count the days from delivery, not from the day you wrote it, and keep the proof.

LandlordPro generates the notice against the state's rule, dates it, records when it was sent, and carries the new rent onto the rent roll on the right day so the ledger and the notice agree.
