Maryland Rent Increase Rules: Caps, Notice Periods & Limits (2026)

How much a landlord can raise rent, and what notice they must give

At a glance

• Rent cap: 马里兰无全州租金上限；部分地方司法管辖区（如 Montgomery 县、Prince George’s 县）有租金稳定规则，州法为最低保护（floor）。
• Statewide notice law: Yes — see the notice rules below
• Governing statute: Md. Code, Real Prop. § 8-209

Who this covers — and who it does not

This page covers rent increases in Maryland for a residential tenancy — whether there is a cap, and what notice a landlord must give.

It does not cover commercial leases, subsidised housing (which follows federal rules), or any city whose local ordinance differs from the state rule.

Is there a rent cap?

马里兰无全州租金上限；部分地方司法管辖区（如 Montgomery 县、Prince George’s 县）有租金稳定规则，州法为最低保护（floor）。

8-209 仅规范涨租通知，不设幅度上限。部分 county（如 Montgomery County）有地方租金稳定法。

Sources and how to verify them

Every figure on this page comes from the official text or a state court opinion, not from a summary. The table below lists each provision used and the date it was last checked.

Statute	Last verified	Source
Md. Code, Real Prop. § 8-209	2026-10-16	official text ↗
Md. Code, Real Prop. § 8-209 (contract principle)	2026-10-16	official text ↗

Where the official text and a secondary summary disagree, this page follows the official text and says so. Where a provision admits of more than one reading, that is flagged rather than smoothed over.

When you need a lawyer instead of a tool

A self-help guide is the right starting point for understanding your position. Get legal help if:

• You have received an eviction notice — the timeline is now court-driven
• The dispute involves discrimination, unsafe conditions or retaliation
• Your landlord has filed anything in court already
• You are unsure whether a local ordinance changes the state rule

Local legal aid organisations and tenant unions offer free help for qualifying cases. They are independent of this site — we list them because they are the right place to go, not because they link here.
