Statutory cap, exemptions, and notice rules under Md. Code, Real Prop. § 8-208 (local authority)
Maryland is a local-control state for rent increases: there is no statewide cap, and the legislature has never set one. Instead, authority to regulate rent flows from Md. Code, Real Prop. § 8-208, which governs lease terms while leaving the decision to limit increases to individual counties and municipalities. The practical result is that the same one-bedroom can sit under a strict annual ceiling in one jurisdiction and face an uncapped market increase a few miles away. With average rent around $1,615, the spread between a regulated and an unregulated address is the single most important fact for any Maryland landlord or tenant to nail down before signing.
Only a handful of places actually limit rent. Takoma Park, Montgomery County, and Prince George's County run formal rent-stabilization programs, and Takoma Park's ordinance is among the oldest in the Washington region. Cities like Hyattsville, Greenbelt, and Rockville sit in this regulated corridor near the D.C. line. Everywhere else in the state, the increase is whatever the lease and proper notice allow.
Which Maryland cities and counties regulate rent
Rent regulation in Maryland is concentrated in the Washington, D.C. suburbs, not spread statewide. The jurisdictions that limit increases include:
- Takoma Park, one of the region's oldest rent-control ordinances, applying a tight annual ceiling to covered units.
- Montgomery County, operates a county-wide rent-stabilization program.
- Prince George's County, runs its own rent-stabilization program covering eligible rentals.
Nearby cities such as Hyattsville, Greenbelt, and Rockville fall inside this regulated belt because they lie within the counties or municipal lines that have adopted controls. Because the formula varies by county and municipality, the only reliable way to know your number is to confirm the program and effective rate with the specific jurisdiction that governs the address, not a statewide figure, which does not exist.
What's covered versus market-rate
Even inside Takoma Park, Montgomery County, or Prince George's County, not every unit is stabilized. Local programs typically define covered housing by building age, structure type, or ownership, and many newer or owner-occupied properties fall outside the ceiling. The grounding here does not list statewide exemptions because Maryland has no statewide program to exempt anything from, coverage is decided ordinance by ordinance.
If your address is outside a regulating jurisdiction, no percentage cap applies at all. The increase is governed only by the lease and by the notice rules in Md. Code, Real Prop. § 8-208. That is why two tenants paying near the $1,615 average rent can face completely different outcomes at renewal, one shielded by a local cap, the other facing a market-rate adjustment with no ceiling.
The rule everywhere else in Maryland
For the large majority of the state, outside Takoma Park, Montgomery County, and Prince George's County. Maryland imposes no limit on how much rent can rise. A landlord may raise the rent to market for the next lease term, subject to two guardrails: the existing lease cannot be changed mid-term without agreement, and the increase cannot be retaliatory or discriminatory. The mechanism for a lawful increase is a properly delivered notice and the start of a new term, governed by Md. Code, Real Prop. § 8-208 and your written lease.
This is the default that catches most renters off guard. Outside the regulated D.C. corridor, there is no formula to plug in and no cap percentage to rely on, the number is whatever the parties agree to at renewal, which is exactly what the calculator on this page models.
Recent legislative activity
Maryland's framework remains a local-option system: the state has not enacted a statewide cap, and the regulating power continues to rest with counties and municipalities under Md. Code, Real Prop. § 8-208. Proposals to set a uniform statewide ceiling have surfaced in Annapolis in recent sessions, but none has displaced the patchwork of local ordinances in Takoma Park, Montgomery County, and Prince George's County.
For now, the safest move is jurisdiction-specific diligence. Confirm whether your address sits inside a stabilization program, check the current local rate (which varies by county and municipality), and verify the notice your lease and § 8-208 require. Treat any statewide "Maryland rent cap" claim with skepticism, none exists today.

Frequently Asked Questions
How much can a landlord raise the rent in Maryland in 2025?
It depends entirely on the address. In Takoma Park, Montgomery County, and Prince George's County, a local rent-stabilization program sets the ceiling, and the allowable percentage varies by jurisdiction. Everywhere else in Maryland there is no cap, the increase is whatever the new lease term and proper notice allow.
Is rent control legal in Maryland?
Yes, at the local level. Maryland has no statewide cap, but Md. Code, Real Prop. § 8-208 leaves room for counties and municipalities to regulate rent. Takoma Park, Montgomery County, and Prince George's County have used that authority to run rent-stabilization programs; most of the state has not.
How much notice is required before a rent increase in Maryland?
A rent increase generally takes effect only at the start of a new lease term, delivered through proper written notice under your lease and Md. Code, Real Prop. § 8-208. Regulating jurisdictions like Takoma Park and Montgomery County may impose their own additional notice rules, so confirm the requirement with the local program governing your unit.
Does Maryland's rent cap apply to my unit?
Only if your unit sits inside a regulating jurisdiction and meets that program's coverage rules. If your address is outside Takoma Park, Montgomery County, or Prince George's County, no cap applies at all. Even within those areas, newer buildings and certain owner-occupied properties are often excluded, so verify coverage with the specific county or city.
