DC rent control increase 2026 Rent Control Year 2026 runs May 1, 2026 through April 30, 2027. Standard cap 4.1%. Elderly/disability cap 2.1%.

The RY 2026 caps, in one paragraph

The Rental Housing Act of 1985 (D.C. Official Code §42-3501.01 et seq.) caps annual rent adjustments on rent-controlled units at the Consumer Price Index for Urban Wage Earners (CPI-W) for the Washington-Arlington-Alexandria DC-VA-MD-WV MSA, 12 months ending the prior December, with two tiers: standard tenants get CPI-W plus 2 percentage points, never exceeding 10%; elderly 62+ or disability-registered tenants get CPI-W only, never exceeding 5%. For RY 2026 (May 1, 2026 – April 30, 2027) the published figures are 4.1% standard and 2.1% elderly/disability. The authority is §42-3502.08(b)(2)(A).

Last year (RY 2025, May 1, 2025 – April 30, 2026) the figures were 4.8% standard / 2.5% elderly. The CPI-W reading dropped between the two reference periods, which dragged both caps down. Landlords who had been planning increases on the May 1 boundary need to recompute against the lower 2026 figures before serving notice — a Form 8 with last year's number in it produces an unlawful overcharge that exposes the landlord to treble damages and attorney's fees under §42-3509.01.

Who is covered, who is exempt

DC rent control is narrower than most landlords assume. The statute covers a unit only if all of these are true:

1. The building's certificate of occupancy was issued on or before December 31, 1975. New construction after 1975 is exempt under §42-3502.05(a)(4). The exemption travels with the building, not the unit, so a 1973 building that was rehabbed in 2010 is still covered.
2. The owner has 5 or more rental units in the District. Natural-person landlords with 4 or fewer rental units are exempt under §42-3502.05(a)(3). The unit count is across all DC properties owned by the same landlord, not per-building. LLC and corporate landlords are covered regardless of unit count.
3. The unit is not federally or DC subsidized. Section 8 vouchers, LIHTC, and DC Housing Authority units operate on their own rent rules.
4. The unit is registered with RAD. Every covered housing accommodation must file Form RAD-1 and maintain a current registration. An unregistered building cannot lawfully take any rent increase, including the RY 2026 increase, until registration is current.

If you are unsure whether your unit is covered, the DC rent calculator walks the four conditions in order and either returns the RY 2026 cap or routes you to the exempt-unit guidance. The DC Rent Registry public lookup at rentregistry.dc.gov is the canonical source — it shows each covered unit's registered ceiling rent and last filed Form 9.

RAD Form 8 — content and the 60-day effective-date rule

The Notice to Tenant of Rent Adjustment, RAD Form 8, is the only instrument that lawfully takes an annual rent increase under the RHA. It must contain:

• The current rent and the new rent in dollars.
• The dollar increase and the percentage increase.
• The cap percentage being claimed (4.1% standard or 2.1% elderly/disability for RY 2026), with citation to §42-3502.08(b)(2)(A).
• The date of last rent adjustment (used to verify the 12-month frequency rule under §42-3502.08(g)(1)).
• The effective date — at least 61 days after tenant receipt, lining up with the next first-of-the-month rent due date.
• The tenant's right to file a tenant petition with RAD if they believe the adjustment is unlawful.
• The landlord's name, address, and signature.

The 60-day floor is firm. The increase cannot take effect until the first day rent is normally paid that occurs more than 60 calendar days after the tenant receives the notice. A notice hand-delivered May 1, 2026 takes effect August 1, 2026 for a first-of-the-month tenant (May 1 + 60 days = June 30; the next first of the month is August 1, since June 30 is a Tuesday and the rule requires the first regular rent date after the 60th day). Mailing service tacks 5 calendar days on under the standard notice-delivery presumption, so a notice mailed May 1 functionally gets to a tenant May 6, 60 days later is July 5, and the first rent date after July 5 is August 1 — same effective date in this case but not always.

After the increase takes effect, you have 30 days to file RAD Form 9, Certificate of Filing, with the Rental Accommodations Division. Form 9 is the post-increase record-of-filing and is what the public Rent Registry indexes. The free DC notice generator emits a printable Form 8 with all required content for RY 2026, with the effective-date math run automatically against the tenant's normal rent-due day.

Banking — the unused-RAA rule

DC permits banking, but on a 12-month frequency cap. §42-3502.08(g)(2) says the right to adjust rent annually is retained even if not exercised in the year it accrued — so an unused RY 2025 4.8% can be taken later. §42-3502.08(g)(1) says no more than one rent increase in any 12-month period for the same unit — so the banked increase and the current-year increase cannot stack into a single notice.

The practical sequence for a landlord who skipped RY 2025:

1. Choose either RY 2025 (4.8%) or RY 2026 (4.1%) for the next increase. The higher number is RY 2025; the lower is RY 2026. You can take RY 2025 now if 12 months have elapsed since the last rent adjustment on this unit.
2. Whichever you take, the next increase on the same unit cannot be served until 12 months after this one.
3. The cap-applicable date is the date the new rent takes effect, not the date the notice is served. So a notice served May 15, 2026 with August 1, 2026 effective date can still claim the RY 2026 percentage even though the notice service date was mid-RY transition.

The DC calculator takes the last-increase date and either returns the available RY 2026 cap or surfaces the 12-month blackout period when the prior increase is too recent.

The elderly/disability tier — registration requirements

The 2.1% RY 2026 cap is half the standard cap, but it doesn't apply automatically. The tenant must:

• Be at least 62 years old, or be disability-registered with the DC Office of Disability Rights.
• Occupy the unit as their primary residence.
• Have household income below the DC Median Family Income threshold set by DHCD (refreshed annually).
• File a tenant registration form with the Rental Administrator. Once registered, the elderly/disability cap applies for the duration of their occupancy.

If you believe a tenant qualifies but has not registered, the right course is to serve the standard 4.1% notice (which the tenant can accept) and separately encourage the registration filing. Serving a 2.1% notice to an unregistered tenant under the assumption they qualify can cause Form 9 misclassification and a refund obligation once RAD audits the file.

The eligible-tenant cap is a tenant-specific protection. If a registered elderly tenant moves out and a non-elderly tenant moves in, the unit reverts to the standard cap. Vacancy adjustments under §42-3502.13 are governed separately and capped at the lower of 10% of the current ceiling or the rent of a substantially-identical unit in the same housing accommodation.

What happens if you overshoot RY 2026

The penalty structure under §42-3509.01 is unforgiving:

1. Restitution of the overcharge — the tenant recovers every dollar paid over the lawful ceiling, with interest.
2. Treble damages on willful overcharges. "Willful" includes overcharges where the landlord either knew the cap or should have known — a Form 8 with last year's percentage on it meets the second prong of the standard.
3. Attorney's fees awarded to the tenant. RAD petitions and DC Superior Court suits both award fees on prevailing tenant claims.
4. Building-wide audit risk. A finding of overcharge on one unit triggers RAD review of the rest of the building, including registration status and Form 9 filings. Landlords who guess at the cap routinely surface multi-unit overcharges in the subsequent audit.

How RentCeiling enforces RY 2026 for you

The free DC calculator takes (current rent, tenant tier, last-increase date) and returns the RY 2026 lawful max with the §42-3502.08 citation, the 12-month frequency check, and the 60-day effective-date computation against your tenant's first-of-the-month rent cycle. The DC Form 8 notice generator consumes the same inputs and emits a printable RAD Form 8 with all required content for RY 2026, including the right cap percentage and the right effective date — no manual recompute, no last-year-percentage trap. The four-California-rent-caps explainer is California-specific but the same principles apply to DC: read the statute, run the math, cite the section. The /compare hub shows how DC's 4.1% standard cap stacks against the other 9 jurisdictions modeled here. Open rule-set at /rules/index.json.
