Maryland Rent Increase Laws: What Landlords Can and Cannot Do
Maryland has no statewide rent control, but a growing list of counties stabilize rents, and the notice period runs sixty to ninety days. Here is how to raise rent legally in 2026.
Raising the rent in Maryland depends heavily on where the property sits. There is no statewide rent-control cap, but a growing number of jurisdictions – led by Montgomery County – now stabilize rents, and the notice period runs longer than in most states. The written-notice rules, the local cap if any, and the bar on retaliatory or discriminatory increases all shape when and how you may raise the rent.
This guide covers whether Maryland has rent control, how much notice you must give, when you can raise the rent, and the limits that still apply. If you are setting rent for a new applicant, our overview of how to screen tenants step by step pairs well with the rules below.

Key Takeaways: Maryland Rent Increase Laws
- No statewide cap, but growing local control. Most of Maryland has no cap, but Montgomery County, Prince George’s County, and Baltimore City stabilize rents.
- Montgomery County limits increases to the consumer price index plus three percent, capped at six percent, around five and seven-tenths percent for 2025 to 2026.
- Notice is sixty to ninety days, at least sixty in most areas and ninety in Montgomery County.
- Check the local program. The real cap on an increase often comes from the county or city, not the state.
Is There Rent Control in Maryland?
Not statewide, but increasingly local. Maryland has no statewide rent-control cap, so in most of the state a landlord may raise the rent by any amount with proper notice. A growing number of jurisdictions, however, stabilize rents – most prominently Montgomery County, where regulated units are limited to the change in the consumer price index plus three percent, capped at six percent, with the ceiling for 2025 to 2026 set around five and seven-tenths percent.
Prince George’s County and Baltimore City run their own programs, so the real cap on an increase often comes from the county or city rather than the state. The first step for a Maryland landlord is to check whether the property sits in a stabilized jurisdiction and what its current allowable increase is. Our overview of how to screen tenants step by step is a useful companion if you are setting rent for a new tenant rather than a renewal.
How Much Notice Before a Rent Increase in Maryland?
Maryland’s notice period is longer than most. In most of the state a landlord must give at least sixty days’ written notice before a rent increase takes effect, and in Montgomery County the notice is at least ninety days. The notice should state the new rent and the effective date.
Where a stabilization program applies, the increase must also stay within the local cap, so the notice and the cap work together. Our deeper look at Maryland late fee laws covers the related charges that often change alongside the rent.
When Can You Raise the Rent?
Timing is where most rent-increase disputes start. An increase takes effect only at the end of a fixed term, or after the required sixty- to ninety-day notice on a month-to-month tenancy. During a fixed-term lease the rent is locked for the term unless the lease itself contains an escalation clause, so a mid-term increase without that clause is not enforceable.
For a month-to-month tenancy, the increase takes effect only after the required notice period runs. You can read how the underlying tenancy ends and renews on our Maryland eviction notice laws page, which covers the notice mechanics that rent changes share.
Retaliation and Discrimination Limits in Maryland
Maryland bars a retaliatory or discriminatory increase. A landlord may not raise the rent to punish a tenant for filing a complaint, requesting repairs, or exercising a right, and where stabilization applies, exceeding the local cap is itself a violation.
An increase that singles out a tenant because of a protected characteristic is separately unlawful as housing discrimination. For the federal baseline on protected characteristics, see our Fair Housing Act guide for landlords.
Writing a Valid Rent-Increase Notice
A Maryland rent-increase notice is only effective if it is done right. Put it in writing, state the current rent, the new rent, and the exact date the new rent takes effect, and deliver it far enough ahead to satisfy the notice period. A vague or verbal notice, or one that shortchanges the timing, is invalid, and the old rent continues until a proper notice is given.
Keep a copy of the notice and proof of how and when you delivered it. If a tenant later disputes the increase, that dated record is what shows the notice was timely and complete.
Rent Increases and Fair Housing in Maryland
An increase that is lawful in amount can still be unlawful in motive. Raising one tenant’s rent more steeply, or on a different schedule, because of race, color, religion, sex, national origin, familial status, or disability is housing discrimination under the federal Fair Housing Act, which applies in Maryland regardless of the lack of rent control.
The safeguard is consistency: set increases by an objective, even-handed method – market rate, a fixed schedule, or a documented cost basis – and apply it the same way to comparable units. Our deeper look at Maryland security deposit laws shows the same even-handed discipline applied to deposits.
Screening Before You Raise the Rent
A rent increase is also a moment to think about who is in the unit. When a tenant declines an increase and moves on, the next applicant should be screened to the same standard you use for everyone, because the federal Fair Credit Reporting Act governs that report whether you are in Maryland or anywhere else.
Get written consent, pull a consumer report for a permissible purpose, and send an adverse action notice if the report drives a denial. Our Maryland tenant screening laws page and the broader tenant screening laws by state guide cover the screening half of the cycle.
A Compliant Maryland Rent-Increase Process
Turn the rules into one repeatable sequence. First, confirm the tenancy type and the point in the term, since a fixed lease locks the rent until it ends. Second, set the new rent by an objective, even-handed method. Third, prepare a written notice stating the current rent, the new rent, and the effective date. Fourth, deliver it with the full notice period the law requires and keep proof. Fifth, make sure the timing is clear of any recent complaint so the increase cannot look retaliatory.
Handled this way, an increase in Maryland is routine. The same discipline that keeps screening defensible – objective criteria, applied uniformly, documented – keeps a rent increase defensible too.
Common Mistakes That Create Liability
The recurring Maryland errors are raising rent mid-lease without a clause that allows it, giving short or verbal notice, timing an increase right after a tenant’s complaint or repair request, applying steeper increases to some tenants than to comparable others, and – where a local cap applies – exceeding it. Most turn on timing, form, and motive, which is where the law imposes real limits even where the amount is not capped.
Set the number, follow the rules. Whether or not a local cap applies, Maryland regulates the notice, the timing, and the motive of a rent increase. Build the written notice, the full notice period, and an even-handed increase method into your standard workflow.
Documentation and Recordkeeping in Maryland
Because Maryland regulates the notice, timing, and motive of an increase, your records are what prove you followed the rules. Keep a copy of every rent-increase notice, the current and new rent, the effective date, and proof of how and when it was delivered. A complete file is the answer to a tenant who claims the notice was late or never arrived.
Keep the increase method too – the market comparison, schedule, or cost basis behind the number – so you can show the increase was set by an objective standard and applied consistently. If a tenant alleges a retaliatory or discriminatory motive, that record of an even-handed method is your strongest rebuttal.
Set one retention policy and apply it to every tenant and every increase. A consistent multi-year record of notices, delivery proof, and the basis for each increase gives you the evidence to answer a fair housing inquiry or a dispute over whether the rent was lawfully raised.

Do
- ✓Give written notice that states the new rent and its effective date, with the time the law requires.
- ✓Wait until the end of a fixed lease term to raise the rent, unless the lease expressly allows it sooner.
- ✓Apply increases consistently, by the same schedule and method, to comparable tenants.
- ✓Keep the timing clear of any complaint or repair request so the increase is not retaliatory.
- ✓Document the notice and how it was delivered, in case the increase is ever questioned.
Avoid
- ✕Raise the rent mid-lease when the lease does not permit it.
- ✕Skip or shorten the written-notice period the state requires.
- ✕Increase rent to punish a tenant for a complaint, repair request, or organizing – that is illegal retaliation.
- ✕Single out a tenant for a higher increase based on a protected characteristic.
- ✕Rely on a verbal notice instead of a dated written one.
Maryland Rent Increase Laws: FAQ
Is there rent control in Maryland?
Not statewide. Maryland has no statewide cap, but a growing number of jurisdictions stabilize rents, including Montgomery County, Prince George’s County, and Baltimore City.
How much can rent increase in Montgomery County, Maryland?
Regulated units are limited to the consumer price index plus three percent, capped at six percent. For July 2025 through June 2026 the maximum allowable increase is about five and seven-tenths percent.
How much notice must a Maryland landlord give to raise rent?
At least sixty days’ written notice in most of the state, and at least ninety days in Montgomery County, stating the new rent and effective date.
Can a Maryland landlord raise rent during a lease?
No, unless the lease expressly allows it. A fixed-term lease locks the rent until it ends, when the landlord may raise it with proper notice and within any local cap.
Is there a statewide limit on rent increases in Maryland?
No. The state sets no cap, so outside a stabilized jurisdiction a landlord may raise the rent by any amount with proper notice. The caps come from county or city programs.
Can a Maryland landlord raise rent in retaliation?
No. A landlord may not raise the rent to punish a tenant for a complaint, repair request, or exercising a right, and exceeding a local stabilization cap is itself a violation.
Which Maryland jurisdictions have rent stabilization?
Most prominently Montgomery County, along with programs in Prince George’s County and Baltimore City. Always confirm whether the property’s jurisdiction limits increases.
Does a Maryland rent increase need to be in writing?
Yes. The sixty- or ninety-day notice should be in writing and state the new rent and effective date; an improper notice does not start the clock.
How much notice must a Maryland landlord give before raising rent?
It depends on the tenancy. For a month-to-month tenancy a Maryland landlord must give the state’s required written notice before the new rent takes effect; for a fixed-term lease the rent generally cannot change until the term ends. Always put the new amount and the effective date in a dated written notice.
Can a Maryland landlord raise rent in the middle of a lease?
Generally no. Unless the written lease expressly allows a mid-term increase, the rent is fixed for the term, so a Maryland landlord must wait until the lease ends and give proper notice before changing it.
