30 days rent-increase notice.
Many DC buildings built before 1976 are rent-controlled, limiting annual increases to roughly CPI + 2% (with caps). Increases require 30 days' notice and registration.
What this means for you: Whether your unit is rent-controlled is decisive. Newer and exempt buildings can raise rent without the cap.
Your next step: Check your unit's rent-control status with the DC Rental Accommodations Division.
