Key Takeaways
Maryland requires written leases for terms over one year, and leases cannot contain prohibited clauses that waive tenant rights or violate state law.
Deposits are capped at two months’ rent, must be held properly, accrue interest, and must be returned (or itemized dedication provided) within 45 days of move-out.
Landlords must disclose required information and keep rental units safe and habitable to avoid legal consequences.
Rent increases require proper notice, fair housing laws prohibit discrimination, and all evictions must go through the court process.
Maryland landlord-tenant law governs nearly every part of the relationship between you and your residents, from how you handle security deposits to the notice you give before raising rent or filing for eviction.

Lease Requirements Under Maryland Rental Laws
Maryland law allows both written and oral leases, but for any tenancy longer than one year, a written agreement is required to be enforceable.
In practice, you should always use a written lease regardless of term length, because it sets clear expectations and gives you something to point to if a dispute arises.
Maryland places specific limits on what a lease can contain. Landlords cannot include clauses that waive a tenant's right to sue, force the tenant to pay the landlord's attorney fees beyond reasonable limits, or authorize confession of judgment.
Leases for properties in jurisdictions with rent escrow laws must also acknowledge the tenant's right to that remedy. If your lease includes a prohibited provision, a court can refuse to enforce it and may award the tenant damages.
For Baltimore City properties specifically, you'll need a valid rental license and lead paint registration before you can legally collect rent or enforce a lease.
Security Deposit Rules and Maryland Tenant Rights
The security deposit is capped at two months' rent. Charging more than that exposes you to penalties of up to three times the excess amount, plus reasonable attorney fees.
When you collect a deposit, you must provide a written receipt, and the lease must explain the tenant's right to a move-in inspection.
Deposits must be held in a Maryland banking institution, and they accrue interest. As of recent rules, interest is calculated at a simple rate that updates periodically, and it must be paid to the tenant when the deposit is returned for any tenancy of at least six months.
You're required to return the deposit, with interest, within 45 days of the tenant moving out. If you withhold any portion for damages beyond ordinary wear and tear, you must send an itemized list of the deductions within that same window.
Miss the deadline and you can forfeit your right to keep any of the deposit, plus face damages up to three times the amount wrongfully withheld.

Required Disclosures and Habitability Standards
For properties built before 1978, federal and Maryland lead paint laws require disclosure of known lead hazards, distribution of an EPA-approved pamphlet, and registration with the Maryland Department of the Environment.
Lead paint compliance is not optional, and noncompliance can lead to significant liability if a child is harmed.
You also must disclose the name and address of the property owner or the person authorized to manage the property, along with any known latent defects that could affect health or safety.
Maryland law requires landlords to keep rental units fit for human habitation, which means working plumbing, heating, electrical systems, structural integrity, and freedom from serious code violations.
When a unit falls below this standard and the landlord fails to act, tenants can pursue rent escrow, paying rent into a court-held account until repairs are made.

Entry Notice, Rent Increases, and Fair Housing
Maryland does not set a single statewide notice period for landlord entry the way some states do, but lease terms and reasonableness govern access.
Rent increases follow notice rules tied to the tenancy type. For month-to-month tenancies, landlords generally must give at least one month's written notice (and Baltimore City and some surrounding jurisdictions may require longer, such as 60 or 90 days, depending on local law).
You cannot raise rent mid-lease unless the lease allows it.
Fair Housing obligations apply at every stage. Federal law and the Maryland fair housing statute prohibit discrimination based on race, color, religion, sex, national origin, disability, familial status, and additional state-protected categories including marital status and source of income.
That source-of-income protection matters in Baltimore, where Section 8 vouchers are common. You generally cannot refuse a tenant simply because they use a housing voucher.
Eviction Grounds and Process Overview
Eviction in Maryland is a court process, and self-help eviction is illegal and carries serious penalties. The most common grounds are failure to pay rent, breach of lease, and holding over after the tenancy ends.
For nonpayment, a landlord files a "failure to pay rent" complaint in District Court, and a hearing is scheduled. If the court rules for the landlord and the tenant doesn't pay or vacate, a warrant of restitution allows a sheriff-supervised eviction.
Maryland also requires landlords to provide notice before filing nonpayment cases, and Baltimore City has its own added requirements. Breach-of-lease and tenant-holding-over cases follow different notice timelines and procedures.
