State rules
No statewide cap — but Montgomery County (5.2% through June 2027) and Prince George's County run real stabilization programs, and Takoma Park has its own. Statewide, an increase needs 60 days' written notice; Montgomery County requires 90.
| Amount cap | No statewide cap; a local program may apply — see below. |
|---|---|
| Notice for an increase | 60 days' written notice for a change in a month-to-month tenancy. |
| Frequency | No statewide frequency limit beyond the notice and lease rules. |
| Retaliation window | Retaliation is barred, as everywhere; the presumption window varies — document your dates. |
| Local rent caps | Not barred statewide; check your city. |
