Late rent fees in Connecticut: the short answer

Waiting period
9 days (4 days for a one-week tenancy)
Maximum fee
the lesser of $5/day up to $50, or 5% of the delinquent rent — $50.00 on $1,200.00 rent
Chargeable from
September 10, 2026, for rent due September 1, 2026
Key condition
A valid written late-charge agreement is required.

Worked example. Rent is $1,200.00, due the 1st. In Connecticut, no fee can be charged before September 10, 2026, and the maximum fee is $50.00 — The lesser of $5/day capped at $50, or 5% of the delinquent rent — 5% of $1,200.00 is $60.00, so the $50 cap binds.

  • 35 chargeable days counted since the grace period ended — $5 each, currently $50.00.
  • Only one late charge may be imposed per delinquent rental payment.
  • A valid written late-charge agreement is required.
  • Connecticut law does not specify where the $5-per-day count begins. CompliMaint counts from the end of the grace period, which produces the lower figure.

The order these three things happen in

Rent is late, a fee may become chargeable, and only later does a notice to vacate become an option. Running them together is the mistake that gets a case thrown out, and Connecticut sets each one separately.

  1. Rent is due. The lease sets the day; nothing here overrides it.
  2. Before a late fee. Tenants have a statutory grace period - nine days for month-to-month or longer tenancies, four days for a one-week tenancy.
  3. What the fee may be. The late charge is capped at the LESSER of $5 per day up to $50, or 5% of the delinquent rent - so on $600 rent the maximum is $30, not $50. Where the rent is subsidized the 5% is measured against the tenant's own share. Only one late charge may be imposed per delinquent payment, and a valid written late-charge agreement is required.
  4. Before an eviction filing. Evictions require a notice to quit served in accordance with state law before a case is filed.

A late rent notice is none of those things — it is a demand for payment, and it carries no statutory timeline of its own. It is what you send to get paid without starting anything formal, which is why it is usually the cheapest thing that works.

Is this an eviction notice?

No, and the difference matters in Connecticut. An eviction filing has to be preceded by the notice above — evictions require a notice to quit served in accordance with state law before a case is filed. A late rent notice has no prescribed wording or waiting period because it is not a legal step; it is a bill with a date on it. The generator’s final notice says so on its face, so nobody receiving it can mistake it for a court document.

When is rent considered late in Connecticut?

The day after the date in the lease. That date is the lease’s to set and Connecticut law does not override it. What state law governs is the next question — how long a landlord has to wait before charging anything for it.

How late can you pay rent in Connecticut before a late fee?

Tenants have a statutory grace period - nine days for month-to-month or longer tenancies, four days for a one-week tenancy.

Worth being precise about what that period is: it is the point at which a fee may be charged. It is not a window in which rent is not owed. The balance is due from the lease date either way, and paying inside the period avoids the fee, not the obligation — which is also why a notice sent during it is a reminder rather than a demand for a fee that isn’t chargeable yet.
