The DC rent increase limit, for a stabilised unit.
The District caps stabilised units at the CPI plus two points, to a ceiling of ten per cent, and lower where the tenant is elderly or disabled. As in New York, whether the unit is stabilised at all is the question that settles the rest.
Letting law is written below the country here, so the rules differ inside it.

From 24 Sep 2026 the rent goes from $850.00 to $867.00, +$17.00 a month. There is no rent index here. United States, District of Columbia caps the yearly rise at 2,0 % plus CPI, never above 10,0 % (Rental Housing Act, D.C. Code § 42-3502.08), and 2,0 % is what that comes to.
Check before you send
- United States, District of Columbia caps the yearly increase at 2,0 % under Rental Housing Act, D.C. Code § 42-3502.08, so 3,0 % has been brought down to it. Confirm the dwelling is inside the statute before relying on the ceiling, and check whether the city caps lower.
- No CPI was supplied, so the ceiling has been taken as 2,0 %, the fixed part of the formula alone. The lawful ceiling is that plus the CPI United States, District of Columbia publishes, to a maximum of 10,0 %.

Nobody here has read these rules in the law of United States, District of Columbia yet, so every figure above is a plausible default rather than a confirmed one. Dardaris will not act on an unconfirmed rule on its own, and neither should you: check it in the source before you send anything.

What the rules actually say
The rules Dardaris applies in the District of Columbia.
Every line below is read off the same jurisdiction pack the product runs on, and each one says whether anybody has confirmed it in a source.
- Index
Statutory cap: 2% plus CPI, to 10%
The CPI is the one United States, District of Columbia names, published for the region rather than nationally. Enter the published figure rather than a national headline rate.
Not confirmed in a source yet. Check it before you act on it.
- Formula
new rent = current rent × (1 + the lower of (2% + CPI) and 10%)
CPI plus two points, to a ceiling of ten, and only for rent-stabilised units. An elderly or disabled tenant is capped lower. A building outside stabilisation is not capped at all.
Not confirmed in a source yet. Check it before you act on it.
- Notice
A written demand is required
Written notice is required, and the period depends on the size of the rise and on how long the tenant has been there. Confirm it before you send.

- Back claim
Nothing can be back claimed
A rent rise runs from the date the notice takes effect and is never back-claimed in the United States.
Confirmed in a primary source
- Statutory ceiling
2 % plus CPI, never above 10 %
CPI plus two points, to a ceiling of ten, and only for rent-stabilised units. An elderly or disabled tenant is capped lower. A building outside stabilisation is not capped at all. Check the exemptions before relying on the ceiling: a dwelling outside the statute is not capped by it, and a city inside the state may cap lower.

The questions that follow.
- What is the DC rent increase cap?
- The consumer price index plus two percentage points, capped at ten per cent, under the Rental Housing Act at D.C. Code section 42-3502.08, and only for rent stabilised units.
- Is the cap lower for some tenants?
- Yes. An elderly or disabled tenant is capped lower than the standard figure. Confirm which applies before you send a notice.
- Does DC rent control reach every building?
- No, and where it does not the District does not cap the amount. The lease and the statutory notice rules are the whole answer, as in an uncapped state.
The same calculator, under other law.
A rent rises differently in each of these, and the page for each one says how. Anywhere else, the calculator still runs on that jurisdiction's own pack.
The calculation takes a minute. The date is what costs you.
Nobody forfeits a year because the arithmetic defeated them. They forfeit it because the anniversary fell in a quiet month, the index was not out yet, and by the time it was, there was nothing to remind them.
- It watches the anniversary for youDardaris holds the lease, its reference quarter and its anniversary, and tells you a revision is due rather than waiting to be asked.
- And works it out on the right two figuresThe reference quarter the lease names, against the same quarter a year earlier, applied to the rent in payment. The DPE block and the twelve month window are part of the same answer.
- But it does not send itA letter that raises somebody's rent waits for you. Dardaris prepares it and says what it is based on, and you are the one who decides it goes.
The number is the easy part.
Dardaris keeps the lease, raises the invoice, matches the payment and writes down what it did. Bring one building and watch a month before you decide anything.
