Are Landlords Responsible for Pest Control in Maryland?

In Maryland, landlords are generally responsible for pest control when an infestation threatens the health or safety of the people living in the rental. That duty comes from the implied warranty of habitability written into every residential lease under Maryland Real Property §8-212, and a landlord cannot contract around it.¹ Two things can shift that responsibility: local code provisions (especially in Baltimore City) and tenant conduct that either caused the problem or blocks treatment.

What Infestations the Law Covers

Maryland Real Property §8-211 lists the serious defects a landlord must fix. Rodent infestations are named directly, but only when they affect two or more units in the same building.² Once rats or mice cross apartment lines, the statute treats them as a building-wide problem for the owner to handle.

Other pests are covered through the statute’s broader catch-all for any condition that presents a health or fire hazard to the dwelling.² Bed bugs, severe cockroach problems, termites, and similar infestations qualify when they create a real health threat. Cockroaches, rodents, and bed bugs can trigger allergic reactions, spread disease, and contaminate living spaces, and at that level the landlord’s duty kicks in. The statute applies to single-family homes and multi-unit buildings alike, whether publicly or privately owned. The only carve-out is farm tenancies.

When the Tenant Is on the Hook Instead

The warranty of habitability has limits. A landlord has a defense under §8-212 if the tenant, someone in the tenant’s family, or a guest actually caused the infestation.¹ Letting garbage pile up, leaving food exposed, or otherwise creating conditions that attract pests can put the problem on the tenant. Courts look at whether the tenant’s behavior, rather than a structural issue or a building-wide problem, was the real cause.

Access matters too. Pest treatment usually takes multiple visits and cooperation from the tenant. If the landlord tried to fix the issue but was denied reasonable access, that’s also a defense.¹ A tenant who won’t let the exterminator in, or who won’t prep the unit as instructed, risks losing the ability to hold the landlord accountable.

Single-family rentals are the trickiest case. Some leases try to hand routine pest prevention to the tenant. Because §8-211 covers single-family homes the same as apartments, a lease clause cannot override the landlord’s duty to address a serious health-threatening infestation. Day-to-day upkeep, though, like keeping the kitchen clean and taking out the trash, still belongs to the person living there. Disputes tend to land right on the line between routine prevention and a serious defect.

Extra Rules in Baltimore City

Baltimore City’s housing code adds specifics. The owner of any building has to keep both the interior and exterior free from pest infestation and must ratproof the entire structure, including blocking entry points with resistant materials and paving basement areas that touch the soil.³

The city code splits responsibility by building type. In a single-unit home, the occupant handles extermination of insects, rodents, and other pests, with wood-destroying insects like termites excluded. In a multi-unit building, the occupant is responsible only when that one unit is the only one affected. Once the infestation reaches common areas or another unit, it becomes the owner’s problem.³ These local rules run alongside state law, and the Maryland Attorney General’s office notes that local ordinances can provide additional tenant protections.⁴

How to Put Your Landlord on Notice

Before any legal remedy is available, the landlord has to have proper notice. Maryland law recognizes three methods:¹

Certified mail listing the specific pest problem, which produces a signed receipt showing when the landlord got the notice.
Actual notice, meaning the landlord personally observes the infestation or is told directly. Verbal notice counts, but proving it later without documentation is harder.
A written violation notice issued to the landlord by a local housing inspector or other government agency.

Certified mail is the safest route because the return receipt pins down the date. If you notify by phone or in person, back it up in writing. Date the letter, name the pest, describe where you’ve seen them, and keep a copy along with any photos. After the landlord has notice, repairs must be made within a reasonable time, which the statute does not define with a specific number of days; severity drives what counts as reasonable.¹

What You Can Do If the Landlord Won’t Act

Maryland gives tenants several ways to push back when a landlord ignores a serious pest problem.

Sue for Damages or Withhold Rent Under §8-212

Under §8-212, you can file a lawsuit for damages and ask the court to reduce (abate) your rent for the period the infestation persisted. You can also refuse to pay rent entirely and raise the infestation as a defense if the landlord sues to evict or collect. Neither remedy requires paying rent into escrow first.¹ Withholding is a serious step. If the landlord sues, you’ll need to prove the infestation was real, that it posed a genuine health or safety threat, that you gave proper notice, and that the landlord failed to fix it within a reasonable time. Multiple tenants dealing with the same building-wide problem can join in one lawsuit.

File a Rent Escrow Case Under §8-211

Rent escrow is a different route. Rather than withholding rent outright, you pay it into a court-supervised account while the landlord fixes the problem. That protects you from a nonpayment eviction while keeping financial pressure on the landlord. You file the Complaint for Rent Escrow and Breach of Warranty of Habitability (form DC-CV-083) in the District Court for the county where the rental sits.⁵ You must have given the landlord notice and allowed a reasonable time for repairs first.⁴

If the court finds the landlord breached the warranty, it can order any combination of the following:²

Order the landlord to exterminate the pests and correct the conditions behind the infestation.
Abate the rent by an amount the court considers fair for the period you lived with the problem.
Release escrowed funds to pay a person or agency to carry out the pest treatment.
Appoint a special administrator to oversee repairs and pay for them out of the escrow account.
Return the escrowed rent to you if the landlord makes no good-faith repair effort within six months.
Terminate the lease so you have a way out of a unit the landlord refuses to make livable.

Report to Code Enforcement or Ask the AG to Mediate

Court isn’t the only route. You can report the infestation to your local housing inspection office or code enforcement agency. A government inspection creates an official record of the conditions, and a written violation notice from the agency itself qualifies as formal notice to the landlord under §8-212. That helps if the landlord disputes how serious the problem is. The Attorney General’s Consumer Protection Division also runs a mediation unit for landlord-tenant disputes; the hotline is 410-528-8662 or 888-743-0023 toll-free.⁴

You’re Protected From Retaliation

Some tenants stay quiet about pests because they’re afraid the landlord will retaliate. Maryland Real Property §8-208.1 prohibits that. A landlord cannot evict you, threaten eviction, raise your rent, cut your services, or terminate a periodic tenancy because you reported a health or safety complaint, filed a lawsuit, or took part in a tenants’ organization.⁶

The protection lasts six months after the protected action. Within that window, an eviction attempt or rent hike is presumed retaliatory, and a court that finds retaliation can award damages up to three months’ rent plus reasonable attorney fees and court costs.⁶ One catch: you generally need to be current on rent when the alleged retaliation happens, unless you are lawfully withholding under §8-211 or your lease.
