Bed bug liability in rental housing
Bed bug laws in Maryland
Who pays for treatment?
Habitability law only
No state bed bug statute, and Maryland is the most county-dependent state covered so far — the practical answer genuinely changes between Baltimore City, Baltimore County, Montgomery and Prince George's. What is uniform is the remedy: where a condition poses a serious and substantial threat to life, health or safety and the landlord fails to fix it in a reasonable time, you either file a rent escrow action and pay rent into court, or withhold and raise the condition as an affirmative defense when they sue. Do not simply stop paying — Maryland expects you to use one of those two routes.
- Who pays for treatment
- Landlord, subject to the local code
- Landlord response deadline
- Reasonable time after written notice
- Disclosure before lease
- No state-level duty
Which county are you in?
The answer genuinely differs depending on where in Maryland you are. Find yours below.
Baltimore City
City of Baltimore.
- Who pays
- Landlord under the city housing code

The city code makes an occupant of a multiple-family dwelling responsible for extermination only IF THEIR UNIT IS THE ONLY ONE AFFECTED; the owner must maintain shared, common and public areas and remains responsible for repairs in all units. In practice that exception rarely holds — lawyers who litigate these cases report that a tenant with bed bugs in an apartment building is almost never the only one affected, and a shared wall is not something you can treat yourself. Ask your neighbours and request the building pest control records before accepting an only-your-unit answer. Alongside this, the City Code of Public Local Laws art. 4 § 9-9A lets a tenant raise a material breach of the lease, or a repudiation of a written inducement to rent, as a defense to a rent or possession action or as the basis for their own action, with the rent escrow procedure applying. A landlord whose treatments simply fail can still be liable, and one who removes a complaining tenant then re-lets to an unsuspecting one risks Consumer Protection Act, negligence and fraud claims.
Baltimore County
Baltimore County, which is separate from Baltimore City.
- Who pays
- Landlord under the Livability Code
- Deadline
- Reasonable time
- Disclosure
- No
Stronger than the city on infestation. Baltimore County Code art. 35, tit. 5 requires premises to be kept clean, safe, sanitary and free of infestation by pests including bed bugs, requires prompt extermination by methods that do not endanger health, and requires the OWNER to exterminate any infestation in the building or on the premises BEFORE renting or leasing any unit. Where a structure has only one housing unit the tenant is responsible; where it has two or more, the owner is — the sole exception being an infestation caused by the tenant failing to take reasonable action to prevent it within their own unit. The county also has its own rent escrow law at §§ 13-7-301(f), 13-7-302 and 13-7-313, letting rent be paid into court where serious defects go uncorrected. The Livability Code is enforced by the Department of Community Development, so a code complaint runs in parallel with any escrow action.

State rent escrow under Real Prop. § 8-211 is available everywhere, and the Maryland Minimum Livability Code sets the floor. Beyond that the county or municipal code decides who pays for extermination, and the variation is real — check your county's housing or livability code directly rather than relying on a statewide answer.

What to do, in order
Photograph everything before you touch it
Live insects, shed skins, dark staining along the mattress seam. Timestamps are the evidence.
Notify the landlord in writing
Email or certified letter, never a phone call alone. Written notice is what starts the clock in every state that has one.
Do not throw out furniture yet
Discarded items can't be inspected, and moving them spreads the infestation down the hallway.
Let the deadline above run
Escalating before it expires generally forfeits the remedy.
Escalate to the housing agency, then to court
An independent inspection report is worth more than your own photographs. Rent withholding rules vary sharply — check the section above before you try it.
