District of Columbia Rent Increase Calculator 2025 Statewide Cap

If you rent or own a covered unit in the District of Columbia, the bottom line is set by statute: under D.C. Code § 42-3502.08, the Rental Housing Act of 1985, rent on a rent-controlled unit cannot rise faster than the DC Metro Area CPI plus 2%. For 2025 that ceiling works out to 5%, built on the 2024 annual DC Metro Area CPI-U of 3% reported by the Bureau of Labor Statistics. The same statute imposes a hard backstop: no annual increase on an occupied controlled unit may exceed 10%, even when inflation runs hot.

D.C. is one of the few jurisdictions with a genuine citywide rent stabilization program rather than a patchwork of local ordinances, so the cap reaches across the whole District for buildings that fall inside it. But coverage is the catch. The Act exempts large categories of housing, and a vacated unit can reset to market under vacancy decontrol. Average rent in the District sits around $1,954, and whether the cap protects you turns entirely on your building's age, ownership, and occupancy status, not the rent figure itself.

What D.C. Code § 42-3502.08 actually caps

The Rental Housing Act of 1985 governs rent on units enrolled in the District's rent stabilization program. For a covered, occupied unit, the annual ceiling is the DC Metro Area CPI + 2%, with a firm 10% maximum regardless of how high inflation climbs.

A few points distinguish D.C. from states with no rent control:

• The cap is citywide and statutory, not a local council ordinance that varies block to block.
• It applies to the increase, not the starting rent. A landlord who has not raised rent in years cannot stack multiple years of skipped increases into one jump beyond the annual ceiling.
• The CPI component is reset each year, so the 5% figure is specific to 2025 and will move with the next BLS reading.

How the 2025 number is set

The District does not pick the cap arbitrarily. The variable half of the formula is the DC Metro Area CPI-U, 2024 annual, which the Bureau of Labor Statistics measured at 3%. The statute adds a flat 2% on top of that inflation figure, producing the 2025 ceiling of 5%.

Because the inflation input is tied to the prior year's annual CPI, the cap is predictable: you can read the BLS number and add two points. The only time the formula stops governing is when CPI + 2% would exceed 10%, at that point the 10% statutory maximum takes over and caps the increase, no matter what the index shows.

Which units are exempt from the cap

This is where most disputes start. The Act carves out broad categories of housing that the cap does not touch:

• Buildings constructed after 1975, newer construction is outside rent stabilization entirely.
• Single-family homes and condominiums, which are generally not enrolled.
• Vacant units, under vacancy decontrol, once a tenant moves out the landlord may reset the rent to market, then the cap resumes from that new figure.
• Federally subsidized units where HUD sets the rent, since the rent is already governed by the federal program.

If your unit falls into any of these buckets, the 5% ceiling does not protect you, a landlord can raise rent by any amount the lease and market allow. Confirm your building's construction date and program status before assuming you are covered.

Notice and enforcement

Even where the cap applies, an increase is not automatic. Rent stabilization in the District is paired with just-cause protections under D.C. Code § 42-3505.01, which limits the grounds on which a landlord can end a tenancy and feeds into how and when rent changes can be imposed.

If you believe an increase exceeds the CPI + 2% ceiling, breaches the 10% maximum, or was applied to a unit that is not actually exempt, the dispute is handled through the District's rental housing administrative process rather than ignored. Keep written notice of the proposed increase, your current rent, and your building's registration status, those three documents decide most cases.

Key Rules Summary

Units Exempt from the Cap

Even where a cap applies, the following unit types are typically not covered:

• Buildings constructed after 1975
• Single-family homes and condos
• Vacant units (landlord may reset rent to market on vacancy, "vacancy decontrol")
• Units subsidized under federal programs where rent is set by HUD

If your unit is exempt, the landlord may raise rent to any market-rate amount with proper notice.

Frequently Asked Questions

How much can my landlord raise the rent in D.C. in 2025?

For a rent-controlled unit, no more than 5% in 2025, the DC Metro Area CPI of 3% plus the statutory 2% under D.C. Code § 42-3502.08. No annual increase on an occupied controlled unit may exceed the 10% statutory maximum.

Is rent control legal in the District of Columbia?

Yes. D.C. has a longstanding citywide rent stabilization program under the Rental Housing Act of 1985 (D.C. Code § 42-3502.08). Unlike states that preempt local rent control, the District itself sets and enforces the cap.

Does my landlord have to give notice before raising the rent?

Rent stabilization is paired with just-cause tenancy protections under D.C. Code § 42-3505.01, and a covered increase must follow the District's process. Keep the written notice, your current rent, and your building's registration status to challenge an improper increase.

Does the cap apply to my unit?

Not always. The Act exempts buildings constructed after 1975, single-family homes and condos, vacant units (vacancy decontrol), and HUD-subsidized units. If your unit is in one of those categories, the 5% ceiling does not apply and rent can rise to market.
