Rent Increase Rules in DC: Rent Control Year 2026 (May (2026)

Quick answer

Yes — District of Columbia caps annual rent increases. DC's rent control regime (Rental Housing Act of 1985) caps annual increases for rent-controlled units: the standard maximum is the regional CPI-W + 2%, set each rent control year by the Rental Housing Commission/Rent Administrator. Current Rent Control Year 2026 (5/1/2026-4/30/2027): 4.1% standard; 2.1% for registered elderly/disability tenants.

The cap formula

Standard units: CPI-W (Washington-area, urban wage earners and clerical workers) + 2%. Elderly (62+)/disability tenants (registered with the Rent Administrator): the lowest of (a) Social Security COLA (2.8% for RCY2026), (b) CPI-W (2.1% for RCY2026), or (c) 5%. The Rent Administrator must publish the annual CPI-W figure in the D.C. Register before March 1 each year (D.C. Code § 42-3502.04(k)); the RHC notice sets each year's caps.

For the current period, that works out to Rent Control Year 2026 (May 1, 2026 - April 30, 2027), per RHC notice published Feb 2, 2026: 4.1% standard (CPI-W 2.1% + 2%); 2.1% elderly/disability. (Prior year RCY2025, 5/1/2025-4/30/2026: 4.8% standard / 2.5% elderly-disability, per OTA notice of 1/17/2025 - search-verified.).

Who is exempt

Applies only to units under DC rent control (rent-stabilized housing); many DC units are exempt from rent control (coverage criteria not itemized this session). Elderly/disability lower cap requires the tenant to have registered status with the Rent Administrator; registered lower-income elderly/disabled tenants are also shielded from surcharges from Capital Improvement and Hardship petitions (income limits per RHC notice).
