How much can you raise it in District of Columbia?
In a rent-controlled unit the increase is capped at the Rental Housing Commission's annual CPI-W adjustment plus 2%, with a 10% ceiling. Elderly and disabled tenants are capped at the CPI-W adjustment alone, up to 5%. The adjustment for the year beginning May 1, 2025 was 2.8%, giving a 4.8% cap for most covered units.
Can you raise rent mid-lease in District of Columbia?
No. A fixed-term lease fixes the rent for the term. An increase takes effect at renewal, or on a month-to-month tenancy after proper notice. The exception is a lease that contains its own escalation clause agreed at signing.
Serving the notice so it holds up
Most rent increases that fall apart fall apart on the date, not the amount: the notice went out too late, or nobody can prove when it went out. Count the days from delivery, not from the day you wrote it, and keep the proof.
LandlordPro generates the notice against the state's rule, dates it, records when it was sent, and carries the new rent onto the rent roll on the right day so the ledger and the notice agree.
