Are Landlords Responsible for Pest Control in Maryland?

In Maryland, landlords are generally responsible for pest control when an infestation threatens tenant health or safety. Every residential lease in the state carries an implied warranty of habitability, and serious pest problems fall squarely within it. A tenant can lose that protection by causing the infestation or blocking treatment, and routine day-to-day cleanliness is always the tenant’s job. But the duty to fix a real infestation sits with the landlord, and it cannot be waived by the lease.

What State Law Requires

Maryland Real Property §8-212 obligates every residential landlord to deliver a dwelling that is “fit for human habitation,” meaning free from conditions that create a fire hazard or a substantial threat to the life, health, or safety of the occupants. ¹ The warranty applies from the first day of the tenancy, lasts the whole term, and a landlord cannot contract around it.

A companion statute, §8-211, lists specific conditions landlords have to repair. Rodent infestations are named directly, but with a wrinkle: the statute covers rodents when they affect two or more units in the same building. ² Once mice or rats spread beyond a single apartment, the law treats it as a building-wide problem the landlord must resolve.

The same statute includes a broad catch-all for any condition that presents a health or fire hazard to the dwelling. ² That is how bed bugs, termites, and serious cockroach infestations get swept in even though the statute doesn’t name them. Cockroaches, rodents, and bed bugs can trigger allergic reactions, spread disease, and contaminate living spaces, and when any of them reaches a level that puts occupants at genuine risk, the landlord has to act.

Section 8-211 applies to both single-family homes and multi-unit buildings, publicly or privately owned. Farm tenancies are the one exemption.

When the Tenant Is Responsible

The warranty is not unlimited. Maryland law gives landlords a defense when the tenant, the tenant’s family, or the tenant’s guests actually caused the problem. ¹ Garbage left to pile up, food left out, hoarded clutter, the kinds of conditions that attract pests, can all shift blame back to the tenant. A court will look at whether tenant behavior, rather than a structural issue or a building-wide problem, caused the infestation.

There is also a defense for landlords who tried to treat the unit but were denied reasonable access. ¹ Extermination usually takes multiple visits, and tenants often have to prep the unit beforehand. Refusing entry or skipping the prep steps can wipe out the right to hold the landlord accountable.

Single-family rentals cause the most arguments. Some leases try to put all pest control on the tenant. Because §8-211 covers single-family houses just like apartments, a lease clause cannot override the landlord’s duty to address a serious health-threatening infestation. Routine upkeep, though, like keeping the kitchen clean and taking out the trash, is always on the person living there. The line between prevention and a serious defect is where most disputes land.

Extra Rules in Baltimore City

Baltimore City layers its own housing code on top of state law. The owner of any building has to keep the interior and exterior free from pest infestation and must ratproof the entire structure, which includes blocking entry points with resistant materials and paving basement areas that contact the soil. ³

The city code also draws a cleaner line than the state statute. In a single-unit home, the occupant handles extermination of insects, rodents, and other pests, except for wood-destroying insects like termites. In a multi-unit building, the occupant is responsible only when that unit is the only one affected. ³ Once an infestation reaches common areas or additional units, responsibility shifts to the building owner. The Maryland Attorney General’s office notes that local ordinances like this can provide additional tenant protections beyond state law. ⁴

How to Put the Landlord on Notice

Before you can use any legal remedy, you have to give the landlord proper notice. Maryland law recognizes three ways: ¹

Sending a written letter by certified mail that lists the specific pest problem. The return receipt proves the date the landlord received it.
Actual notice, meaning the landlord personally sees the infestation or is told about it directly. Verbal notice counts, but it is harder to prove in court.
A written violation notice from a local housing inspector or other government agency.

Certified mail is the safest route. Even if you report the problem some other way, follow up in writing. Date the letter, describe the pest, note where you’ve seen it, and keep a copy along with any photos. After notice, the landlord must make repairs within a reasonable time. ¹ The statute does not fix a specific number of days; what counts as reasonable depends on how severe the problem is.

What You Can Do if the Landlord Won’t Act

If the landlord ignores the problem or lets the clock run, you have several options.

Sue for Damages or Withhold Rent

Under §8-212, you can file suit for damages and ask the court to abate your rent for the period the infestation lasted. You can also refuse to pay rent and raise the infestation as a defense if the landlord sues you for unpaid rent or files for possession. ¹ Neither remedy requires you to deposit rent with the court first.

Withholding is a serious step. If the landlord files for possession, you will need to prove the infestation was real, that it was a genuine health or safety threat, that you gave proper notice, and that the landlord failed to fix it within a reasonable time. Tenants dealing with the same building-wide problem can join together in one case.

File a Rent Escrow Action

Rent escrow is a separate route under §8-211. Instead of withholding rent, you pay it into a court-supervised account while the landlord fixes the problem. That protects you from an eviction for nonpayment and keeps financial pressure on the landlord. The filing form is the Complaint for Rent Escrow and Breach of Warranty of Habitability (DC-CV-083), filed at the District Court in the county where the rental is located. ⁵ You must have already given the landlord notice and a reasonable time to repair. ⁴

If the court finds a breach, it has broad authority to order repairs, reduce the rent, release escrow money to pay for extermination, appoint someone to oversee the work, or even terminate the lease. ² If the landlord makes no good-faith repair effort within six months, the court can return the escrowed rent to you.

Report to Code Enforcement

You can also call your local housing inspection office or code enforcement agency. ⁴ An inspection creates an official record of the conditions, and a written violation notice from the agency counts as formal notice under §8-212. That is useful when the landlord disputes how bad the problem really is. The Maryland Attorney General’s Consumer Protection Division also runs a mediation unit for landlord-tenant disputes.

You Cannot Be Punished for Complaining

Many tenants hold off on reporting pests because they worry about rent hikes or eviction. Real Property §8-208.1 bars that. A landlord cannot evict you, threaten eviction, raise your rent, cut services, or end a periodic tenancy because you reported a health or safety complaint, filed a lawsuit, or joined a tenants’ organization. ⁶

The protection runs for six months after the protected action. If the landlord moves against you during that window, the court will presume retaliation. ⁶ A tenant who wins a retaliation claim can recover damages up to three months’ rent, plus reasonable attorney fees and court costs. One catch: you generally have to be current on rent when the retaliation happens, unless you are lawfully withholding under §8-211 or the lease itself.
