Maryland's New Landlord-Tenant Laws: What Every Investor Needs to Know Before Their Next Eviction

Maryland overhauled its eviction and tenant-protection framework in 2025, and a lot of investors haven't caught up. Self-help lockouts are illegal and always have been, but the consequences are now steeper. Every lease needs the Tenants' Bill of Rights attached. And a lawful eviction now runs through a 10-day pay-or-quit notice, a court judgment, a 6-day pre-eviction notice sent through multiple channels, and a 10-day window to store a tenant's belongings after the sheriff repossesses the unit. Skip a step, and a court can vacate your warrant or wipe out your claim to back rent entirely.

Key takeaways:

• Self-help lockouts can cost you the rent you were owed. Change the locks yourself instead of going through the court, and a judge can bar you from collecting the balance at all, on top of damages and attorney's fees.
• Every new or renewed lease needs the current Tenants' Bill of Rights attached, a requirement that's been in place since 2025 and updates annually.
• The eviction timeline is longer than it used to be: a 10-day pay-or-quit notice, a court judgment, a 6-day pre-eviction notice through multiple channels, and a 10-day post-eviction property storage window.
• Baltimore City and Baltimore County run different playbooks on licensing and how many times a tenant can redeem an eviction by paying up.
• The 5% late fee cap and the four-or-more-unit fee disclosure rule are both real, current law, not proposals, and both took effect in October 2025.

A few months ago, I got an urgent call from an investor who had recently built a small portfolio of three rowhomes in East Baltimore. He liked the cap rates on paper and figured the operations would take care of themselves.

One of his inherited tenants had fallen three months behind on rent and stopped responding to texts and calls. Frustrated, he decided to handle it himself. Over a weekend, he waited until the tenant left for the day, had a locksmith swap the deadbolts, boxed up the tenant's belongings, set them on the curb, and texted that they could have their things back once the balance hit zero.

He thought he was just being a decisive property manager. He had actually committed a self-help lockout, which has been illegal in Maryland for years and carries real teeth under the current law.

The tenant didn't panic. They called the police and went to the local district court to get their possession restored. At the hearing, the judge didn't weigh how much back rent was owed. The court focused entirely on the fact that the investor had bypassed the legal eviction process altogether, changed the locks without a warrant, and put the tenant's belongings out without any court order behind it.

The judge ordered him to pay the tenant statutory damages equal to several months' rent, ordered him to cover the tenant's attorney's fees, and barred him from ever collecting the past-due balance. A portfolio that looked clean on a spreadsheet took a real financial hit in a single afternoon, over a shortcut that would have cost him almost nothing to do correctly.

My perspective on asset protection comes from 14 years of licensed real estate experience in Maryland, on top of a background in property valuation, appraisal, and Broker Price Opinions. I look at a rental portfolio the way an underwriter looks at a loan file: where's the actual exposure, not just the return on paper.

Baltimore City and Baltimore County have pulled further apart on tenant protections in the last few years, and relying on an old lease template or gut instinct isn't just risky anymore. It can cost you the rent you're trying to collect in the first place. Here's what actually changed, and what it means for how you run your portfolio.

The Statutory Baseline: Mandatory Lease Provisions

A Maryland residential lease is a heavily regulated document, and a lot of new investors assume that if a tenant signs it, every term holds up. It doesn't work that way. Any lease provision that tries to waive a tenant's statutory rights is void, whether or not the tenant signed it. Four provisions matter most right now.

The Tenants' Bill of Rights Attachment

Since 2025, Maryland requires landlords to physically attach the current Maryland Tenants' Bill of Rights to every new lease and every renewal. The Department of Housing and Community Development publishes and updates the document, with a new version taking effect every October 1. It covers fair housing basics, lead safety requirements, and where to find local enforcement contacts. Skip it, and a tenant has a real argument to challenge the lease in a dispute.

The Itemized Fee Disclosure Rule

If you own or manage four or more residential units, you can no longer advertise a bare rental rate and add fees later. You have to give prospective tenants a written, itemized list of every fee you might charge outside of rent, including things like pet fees, parking, and application costs. If a fee wasn't on that disclosure, you can't enforce it. This rule applies to leases signed or renewed on or after October 1, 2025, and tenants have been able to bring claims over it since February 2026.

The 24-Hour Notice of Entry Rule

Outside of a genuine emergency like a burst pipe or a fire, you need at least 24 hours of written notice before entering an occupied unit. Routine inspections and walkthroughs are limited to 7:00 AM to 7:00 PM, Monday through Saturday.

The 5% Late Fee Cap

As of October 2025, the most you can charge for a late payment is 5% of the unpaid rent balance, not 5% of the full monthly rent if only part of it is outstanding. Maryland doesn't set one statewide grace period before a late fee kicks in. That detail lives in your lease and, in some jurisdictions, local ordinance, so confirm the specific grace period that applies to your property rather than assuming a single number applies everywhere.

Baltimore City vs. Baltimore County: What Actually Differs

One of the more dangerous assumptions an investor can make is treating a rowhome in Baltimore City and a rental in Baltimore County as though they run under identical rules. They don't.

Baltimore City

Every non-owner-occupied rental unit in the city, single-family or multi-family, needs a valid Rental Dwelling License, not just larger multi-unit buildings. Without a current license, you lose your legal right to collect rent at all, a rule that's been in effect since 2019. Before filing a Failure to Pay Rent case, you still need to serve the 10-day written notice to pay or quit. On redemption rights, Baltimore City is the most tenant-favorable jurisdiction in the state: a tenant can pay to stay at any point before the sheriff executes the warrant, and the right survives until a fifth judgment for possession is entered against them within 12 months. Only at that point can you ask the court to foreclose their right to redeem going forward.

Baltimore County

Nearly all rental units in Baltimore County need to be registered and licensed under the county's rental registration code, with narrow exemptions such as units occupied by the owner's relatives or properties with historic designation. This registration requirement is separate from, and in addition to, Maryland's lead-based paint registration for properties built before 1978, which is its own compliance track through the state. Don't confuse the two. On redemption, Baltimore County follows the tighter statewide default: a tenant's right to redeem is cut off once three judgments for possession have been entered against them in the prior 12 months, one fewer than Baltimore City allows.

The Modern Eviction Process: A Four-Step Track

The days of getting a fast judgment and setting furniture on the curb are gone. Maryland's Tenant Possessions Recovery Act, effective October 1, 2025, added real structure to what happens after a judgment. The process now runs through four steps.

1. The 10-day pay-or-quit notice. You serve written notice, by hand delivery, posting on the door, certified mail, or electronic delivery if the tenant has opted into it, giving the tenant 10 days to cure the delinquency. You can't file in court until that window closes.
2. The court judgment. If the notice period passes without payment, you file a Failure to Pay Rent complaint. The court schedules a hearing, and absent a valid defense such as a Rent Escrow claim for uninhabitable conditions, the judge enters a judgment for possession.
3. The pre-eviction notice. Once you have a judgment, you apply for a Warrant of Restitution. Before the sheriff executes it, you must give the tenant written notice of the scheduled date at least 6 days in advance, sent by mail and posted on the door, alongside any electronic channel you have on file. Some local jurisdictions can adjust this window down to 4 days or up to 14, so confirm your specific requirement rather than assuming 6 days applies everywhere. Get the notice wrong, and the court can vacate the warrant or delay the eviction outright.
4. The property storage window. Once the sheriff repossesses the unit, you cannot discard the tenant's belongings immediately. You have to hold their property, without charging a storage fee, for 10 calendar days, giving the tenant a real chance to retrieve it. Only after that window closes does the remaining property count as abandoned, and you can dispose of it through sale, donation, or other lawful means.

A Warrant of Restitution is only good for 60 calendar days once issued. If scheduling or weather pushes the sheriff past that window, the warrant expires and you're back to square one on that step.

Which Path Makes Sense for Your Situation?

If you're buying a property with an existing, inherited tenant, your priority before closing is finding out exactly where that tenancy stands: current on rent, subject to an existing notice, or already headed toward court. Request the rent ledger and any notice history during due diligence, not after you own the problem.

If you already have a delinquent tenant and you're frustrated with the pace of the legal process, your priority is resisting the shortcut. A self-help lockout can cost you the entire back-rent balance you're trying to collect, plus damages and legal fees, all for skipping a process that typically takes a few weeks longer than doing it yourself.

If you're actively growing a portfolio across both Baltimore City and Baltimore County, your priority is a lease template and a compliance checklist that account for both jurisdictions separately, since licensing, redemption rights, and filing procedures don't match across the county line even though the properties might be a few blocks apart.

Whatever position you're in, the through-line is the same: the legal process is slower than a lockout, but it's the only path that keeps your claim to back rent intact.

Frequently Asked Questions

What happens if a landlord doesn't attach the Tenants' Bill of Rights to a lease? It's a real compliance gap. A tenant can point to the omission as a defense in a landlord-tenant dispute, and it can undercut your ability to enforce other lease provisions, including late fees.

Can a Maryland landlord evict a tenant without a sheriff? No. Any attempt to force a tenant out without a court-issued Warrant of Restitution executed by a sheriff or constable, including changing locks, shutting off utilities, or removing a door, is an illegal lockout. The tenant can sue for actual damages, attorney's fees, and statutory damages that can reach several months' rent.

What is a Rent Escrow action in Maryland? If a rental unit has a serious, code-violating defect, such as no heat in winter, a gas leak, or an active infestation, the tenant can pay disputed rent into a court-managed account instead of to the landlord. You can't access those funds until you prove the repairs are complete and signed off by an inspector.

How long is a Warrant of Restitution valid? Sixty calendar days from issuance. If the sheriff hasn't executed it by then, it expires and you have to restart the process.

How many times can a tenant redeem an eviction by paying up? In Baltimore City, a tenant's right to redeem survives until a fifth judgment for possession is entered against them within 12 months. In Baltimore County and most other Maryland jurisdictions, that right cuts off after the third judgment in the same 12-month window.

Does the fee disclosure rule apply to every landlord? No. It applies specifically to landlords who own or manage four or more residential units. Below that threshold, the itemized disclosure requirement doesn't apply, though clear, upfront fee terms are still good practice.

Is the 5% late fee cap the same in every Maryland county? The 5% cap on the unpaid balance is statewide law. What varies locally is the grace period before a late fee can be charged at all, so confirm your specific jurisdiction's rule rather than assuming a single number applies everywhere.

Protect Your Portfolio Before Your Next Eviction

Long-term returns on a rental portfolio don't come from an optimistic spreadsheet. They come from operational discipline before a tenant ever gets a key, and from following the actual process when a tenancy goes sideways.

Before your next lease signing or collection action, run one audit. Pull the current Tenants' Bill of Rights from the DHCD site and confirm it's attached to every active and upcoming lease. Check your late fee language against the 5% cap and your county's grace period. Confirm your notice of entry policy states the 24-hour window. If you're at four or more units, make sure your fee disclosure sheet is complete and matches what you actually charge. None of this takes long, and all of it is cheaper than a single afternoon in rent court.

If you're building or already running a portfolio across Baltimore City and County and want a second set of eyes on your lease templates, licensing status, and eviction process, a strategy call is the fastest way to find your gaps before a tenant, or a judge, finds them for you. If you already have the fundamentals in place and want a broader look at how your portfolio is positioned, a full portfolio review is the next step.
