Baltimore Rent Increase Limit: Guide for Tenants and Landlords

If you’re renting in Baltimore, you’ve probably heard people talk about a "rent increase limit" and wondered what that really means. The good news is the city follows Maryland state rules, which set clear caps on how much a landlord can raise the rent each year. Knowing these limits helps you avoid surprise spikes and keeps the landlord‑tenant relationship smooth.

How the limit is calculated

Maryland doesn’t have a statewide rent‑control law, but Baltimore does impose a cap on annual rent hikes for most residential units. The formula looks at the Consumer Price Index (CPI) for the Baltimore‑Washington area. Basically, the landlord can increase the rent by the CPI percentage plus a small fixed amount, usually 2%. For example, if the CPI shows a 3% rise, the total allowable increase is 5% (3% + 2%).

There are a few exceptions. New constructions built after 2019, single‑family homes, and units that are already on a market‑rate lease may not be subject to the cap. Always ask your landlord for the exact calculation they’re using – a transparent landlord should be able to show you the CPI data and the math.

Practical steps to handle a rent hike

First, check the notice period. Maryland law requires at least 30 days’ written notice for any increase of 5% or less, and 60 days for anything higher. If you get a notice that doesn’t meet these timelines, you can push back and ask for a proper notice before the new rent takes effect.

Second, verify the amount. Compare the proposed increase with the CPI‑based cap. You can find the latest CPI numbers on the Bureau of Labor Statistics website or ask your local housing agency. If the landlord’s figure exceeds the limit, you have the right to dispute it in writing.

Third, negotiate. Even if the increase is within the legal range, you might still be able to negotiate a smaller hike, especially if you’ve been a reliable tenant. Offer to sign a longer lease in exchange for a lower increase – landlords often appreciate the stability.

If you think the increase is unfair or illegal, you can file a complaint with the Baltimore Office of Fair Practices. They’ll review the case and may help mediate between you and the landlord.

For landlords, the key is documentation. Keep records of the CPI data you used, the notice you sent, and any communication with the tenant. This protects you if a tenant challenges the raise.

Bottom line: Baltimore’s rent increase limit is tied to the CPI plus a small fixed add‑on, with clear notice rules. Both tenants and landlords can stay on the right side of the law by checking the numbers, giving proper notice, and keeping communication open. Understanding these basics makes rent adjustments predictable and less stressful for everyone involved.
