Baltimore County Rental Laws: What Tenants and Landlords Need to Know

When you rent a home in Baltimore County, a jurisdiction in Maryland with its own set of rental regulations that align with state law but include local enforcement practices. Also known as Baltimore County rental regulations, these rules govern everything from how much rent can go up to when a landlord can walk into your apartment. Unlike cities with strict rent control, Baltimore County follows Maryland state law—which bans rent caps entirely. That means your landlord can raise your rent by any amount, as long as they give you proper notice. But that doesn’t mean you have no power.

One of the most common misunderstandings is about security deposits, the money tenants pay upfront to cover potential damage, which Maryland law limits to no more than two months’ rent. Also known as rental bond, it must be returned within 45 days after you move out, along with a written itemized list of any deductions. If your landlord misses that deadline, you can take them to small claims court—and win. Another key point: landlord entry, in Maryland, landlords must give at least 24 hours’ notice before entering, unless it’s an emergency like a burst pipe or fire. Also known as notice to enter, this rule protects your right to privacy, even if you’re not home. You can’t be kicked out without a court order, even if you’re late on rent. And if your unit has serious health hazards—like mold, no heat, or broken locks—you have the right to report it to the county housing authority without fear of retaliation.

What you won’t find in Baltimore County are rent control ordinances, mandatory lease renewals, or limits on how often rent can increase. But you will find clear legal pathways to fight back if your rights are ignored. The state’s Maryland Residential Landlord and Tenant Act, the main law covering rental agreements, security deposits, evictions, and repairs. Also known as MRLTA, it’s the backbone of every tenant-landlord relationship here. Whether you’re a new renter, a small landlord managing a single property, or someone trying to fix a broken system, knowing these rules saves money, stress, and time.

Below, you’ll find real-world examples of how these laws play out—from tenants recovering their deposits after being ignored, to landlords avoiding lawsuits by following the 45-day rule. You’ll also see what happens when rules are broken, and how to fix it without hiring a lawyer. These aren’t theoretical guides. They’re based on actual cases, county records, and legal outcomes in Baltimore County. Know your rights. Know your options. And don’t let confusion cost you your security deposit—or your home.
