How much notice is required to raise rent in Maryland?

Under Md. Code, Real Property § 8-209, a landlord must give at least 90 days written notice before raising rent on any residential tenancy longer than one month (which covers most month-to-month and fixed-term leases). For tenancies longer than a week but no more than a month (week-to-week tenancies that have run for at least a full month), the notice period is 60 days. Local jurisdictions can require more notice but not less.

What is § 8-209 of the Maryland Real Property Article?

Section 8-209 is the rent-increase notice statute for residential leases in Maryland. It sets two notice periods (90 days for tenancies longer than a month; 60 days for weekly-to-monthly tenancies), requires written notice in a specified form, and specifies delivery methods (first-class mail with certificate of mailing, or tenant-elected electronic delivery). It applies statewide and is in the same Real Property article as the FTPR statute (§ 8-401) and the residential lease provisions statute (§ 8-208).

Does the 90-day notice apply to fixed-term leases or only month-to-month?

Both. The statute is written by tenancy duration, not lease type. Any tenancy longer than one month, which includes most one-year leases, two-year leases, and month-to-month arrangements that have run longer than a month, requires 90 days written notice before a rent increase takes effect. The clock starts when the notice is delivered, not when the lease is signed.

Can I deliver the rent increase notice by email or text message?

Only if the tenant has affirmatively elected electronic delivery. The default delivery method under § 8-209 is first-class mail with a certificate of mailing. If the tenant has elected (in writing) to receive notices electronically, the notice can be delivered by email, text message, or through an electronic tenant portal. Posting on the door, leaving voicemail, or telling the tenant in person are not statutory delivery methods and do not start the 90-day clock.

What is a certificate of mailing, and why does the statute require it?

A certificate of mailing is a USPS document confirming you sent first-class mail to a specific address on a specific date. It costs about $2 at the post office and serves as proof of mailing if the tenant later disputes when the notice was sent. The statute names this specific method (not just first-class mail alone) because it removes ambiguity about delivery dates if the increase is challenged later.

What happens if I give less than 90 days notice?

The rent increase is unenforceable until 90 days have passed from a proper notice. If you served notice 60 days before the increase date, the tenant continues paying the old rent until day 91 from the original notice. If you continue to demand the higher rent and the tenant pays the old rent, you cannot file an FTPR for the difference. If you file anyway, the case is typically dismissed and the tenant can raise the defective-notice issue as a defense or, in some circumstances, file an affirmative claim for damages.

Do local jurisdictions like Baltimore City have their own rent increase notice rules?

Yes, potentially. Section 8-209 explicitly allows local jurisdictions to require additional notice or provide additional tenant protections that go beyond the state statute. Baltimore City, Montgomery County, Prince George's County, and other municipalities have at various times considered or enacted rent-related ordinances. Check current local law before serving a rent increase notice in any specific jurisdiction. The 90-day state floor is the minimum, not necessarily the binding rule.

Is the 90-day rent increase notice connected to the Tenants' Bill of Rights?

Yes. The Maryland Tenants' Bill of Rights (effective October 1, 2025) names § 8-209 among the statutes landlords must comply with and references the 90-day rent increase notice as one of the tenant protections that must be attached to every new and renewing residential lease. The TBOR did not change the 90-day rule itself (which predates TBOR) but raised its enforcement profile.

Maryland's 90-Day Rent Increase Notice: The 2026 Landlord Guide to § 8-209

Raising rent on a Maryland residential tenant requires written notice. The amount of notice depends on the tenancy length, the content depends on the statute, and the delivery method depends on whether the tenant has elected electronic notice. Get any of those three wrong and the increase is unenforceable until the next properly noticed cycle. This is the 2026 walkthrough of Md. Code, Real Property § 8-209, including how the 90-day rule interacts with the Tenants' Bill of Rights and where local jurisdictions can layer on more protection.

90 days

tenancies > 1 month

§ 8-209 minimum

60 days

weekly-to-monthly tenancies

§ 8-209 minimum

Local override

up but not down

local rules can require more

The 90-day notice rule is not a courtesy. It is the statutory floor. A 60-day notice does not become valid because the tenant did not object. The rent increase simply does not take effect until day 91 from a proper notice.

The rent-increase notice rule is codified at Md. Code, Real Property § 8-209. The broader residential lease framework sits at § 8-208, which covers late-fee caps and prohibited lease provisions. The Maryland Tenants' Bill of Rights effective October 1, 2025 references § 8-209 as one of the tenant protections landlords must comply with and disclose at lease attachment.

For the broader TBOR compliance picture, see Maryland's Tenants' Bill of Rights: Landlord Compliance Guide.

What § 8-209 Actually Says

The statute has two operative pieces: a written notice requirement and a notice-period floor.

Written notice required

A landlord must notify the tenant in writing before increasing rent. Verbal notice, posted signs, voicemails, and conversations during property visits do not satisfy the statute. The written form must clearly state:

The current rent amount
The new rent amount
The effective date of the increase
The landlord's name and contact information

Many landlords use a standardized form. The substantive content matters more than the format.

Notice-period floor by tenancy duration

Tenancy duration	Minimum notice
More than one month (includes most fixed-term leases and ongoing month-to-month)	90 days
More than one week, no more than one month	60 days
One week or less	Not covered by § 8-209

The 90-day rule covers the vast majority of Maryland residential tenancies. Fixed-term leases (one year, two years) and ongoing month-to-month tenancies both fall under the 90-day rule.

Delivery Methods (Strict Statutory List)

The statute names two acceptable delivery methods and requires the landlord to use one of them:

1. First-class mail with a certificate of mailing

The default and most common method. A certificate of mailing (USPS Form 3817, available at any post office for around $2) is a receipt confirming you mailed first-class mail to a specific address on a specific date. It is not the same as certified mail (which requires a signature on delivery). Certificate of mailing just proves the mailing date.

Why the statute names this specific method: if the tenant later disputes when the notice was sent, the certificate of mailing is the landlord's evidence. Plain first-class mail without the certificate works in practice but is weaker if the date is contested.

2. Tenant-elected electronic delivery

If the tenant has affirmatively elected electronic notice (in writing), the landlord can deliver by:

Email
Text message
An electronic tenant portal

The election must come from the tenant. A landlord cannot unilaterally decide to deliver electronically because it is more convenient. The election should be in the lease, a separate written agreement, or a clear written communication from the tenant.

What does NOT satisfy § 8-209

Posting on the unit door (works for the 10-day Notice of Intent under § 8-401(c) but not for rent increase notice under § 8-209)
Voicemail or phone call (not written)
Hand-delivery without a written copy (the written copy is the notice; verbal hand-off is irrelevant)
Tenant verbally agrees (does not waive the statutory delivery requirement)
Lease provision purporting to waive § 8-209 (unenforceable under § 8-208(d), which prohibits lease provisions that waive statutory tenant protections)

When the Clock Starts

The 90-day (or 60-day) clock starts on the date the notice is delivered. For first-class mail with certificate of mailing, the delivery date is the date on the certificate. For electronic delivery, the delivery date is the date the email, text, or portal notice is sent.

The effective date of the new rent must be at least 90 days (or 60 days) after the delivery date. Day 91 is the earliest day the new rent can be charged. Day 90 is too early.

Common Landlord Mistakes

Notice too short

60 days for a 90-day tenancy

Wrong delivery

posting / verbal / informal email

No tenant electronic election

emailed without written consent

The five errors that most commonly invalidate a rent increase notice:

Too few days. Serving 60 days before the effective date on a tenancy that has run longer than a month. The increase is unenforceable until 90 days from a proper notice.
Wrong delivery method. Posting on the door, sliding under the door, leaving a voicemail, or texting without the tenant's written electronic-delivery election.
Verbal election then electronic delivery. The tenant said "yeah email me whenever" but never put it in writing. Default to first-class mail with certificate of mailing if you do not have written electronic-delivery consent.
Notice misses required content. Missing the new rent amount, the effective date, or the landlord's contact information. Defective notice; resend with everything.
Increase exceeds local cap (if one applies). Some Maryland jurisdictions have rent-stabilization ordinances or notice overlays. Check current local law before serving in any specific municipality.

Local Override: Where State Law Is the Floor, Not the Ceiling

Section 8-209 explicitly states that it does not affect or supersede any local law or ordinance that requires additional notice or provides additional tenant protections. In plain English:

More notice is OK. A local jurisdiction can require 120 days, 180 days, or any longer period.
Less notice is not OK. A local jurisdiction cannot reduce the state floor of 90 days (for >1-month tenancies) or 60 days (for weekly-to-monthly).

Several Maryland jurisdictions have considered or enacted rent-related ordinances at the local level over the past several years. Baltimore City, Montgomery County, and Prince George's County are the largest examples. Before serving a rent increase notice on a property in any Maryland municipality, confirm:

The state floor (90 or 60 days under § 8-209)
Whether the property's county or city has a longer notice rule
Whether the property's municipality has a rent-stabilization or rent-cap rule

The Department of Housing and Community Development at dhcd.maryland.gov publishes guidance on the statewide framework. Local jurisdiction ordinances are typically at the county or city housing department websites.

Interaction with the Tenants' Bill of Rights

The Maryland Tenants' Bill of Rights, effective October 1, 2025, does not modify § 8-209's notice periods or delivery methods. What it does do:

Names § 8-209 as one of the statutes landlords must comply with and reference in lease attachments
Requires lease attachment of the current TBOR document on every new lease and every lease renewal (the 90-day rent increase rule is one of the items disclosed)
Raises enforcement profile because tenants signing leases now see the rule in writing on day one, with the source statute named

The substantive change post-TBOR is enforcement awareness. The underlying notice math is unchanged.

Rent Increase vs Other Rent Modifications

The 90-day rule applies to rent increases. It does not apply to:

Lease term extensions at the same rent (not an increase)
Pass-through charges expressly authorized by lease (utility reconciliations, common area fees, parking, etc., if the lease permits them and they are not styled as rent)
Late fees within the 5% statutory cap (see Maryland's 5% Late Fee Cap)
Security deposit adjustments (governed separately under § 8-203)

If the modification is genuinely an increase in the rent itself, § 8-209 governs. If it is a different type of charge, check the specific statute or lease provision that authorizes it.

What Happens If You Serve Defective Notice

The rent increase is unenforceable until 90 days have passed from a proper notice. Three practical implications:

1. The old rent continues

If the tenant pays the old rent during the defective-notice period, that is the full rent owed. You cannot file an FTPR for the difference between the old and new rent during this window because there is no shortfall.

2. You can re-notice and start the clock over

If you discover the defect (e.g., you mailed 70 days before the effective date), you can immediately serve a corrected notice. The 90-day clock starts from the corrected notice's delivery date. The originally intended effective date is delayed by the shortfall.

3. The tenant can raise defective notice as an FTPR defense

If you file an FTPR for the higher rent without a valid notice, the tenant can raise § 8-209 defective notice as a defense. The case is typically dismissed (the amount claimed reflects an unenforceable rent), or the judge reduces the claim to what the old rent would have produced.
