Montgomery County's HOME Act, in effect since July 2024, limits annual rent increases to the rental-component CPI plus 3%, capped at 6%, for buildings that have been occupied for 23 years or more. Takoma Park has had its own stricter ordinance since 1981, capping increases at CPI. Elsewhere in Maryland there is no cap, though 90 days' notice is required for increases on leases of a year or more.
The Department of Housing and Community Affairs publishes the allowable increase each spring for the year starting July 1.
