Connecticut uses a two-part deadline: your landlord must return your security deposit, with interest, by the later of 21 days after your tenancy ends or 15 days after they receive your forwarding address in writing. DepositsBack.app helps you take the next step: a state-specific security deposit notice sent by USPS Certified Mail, with tracking that stays attached to your case. This page summarizes general information from Connecticut General Statutes § 47a-21 and official state sources.
The general deadline is 21 days. Landlords must return the security deposit, with interest, by the later of 21 days after the tenancy ends or 15 days after receiving the tenant's written forwarding address.
You may still be able to send a notice. We show general state information and official sources so you can review your situation and decide your next step.
The Complete Case Bundle includes your notices, USPS Certified Mail history, case summary, evidence checklist, attorney handoff sheet, and official state resources — all in one downloadable ZIP.
If neither the 21-days-after-move-out nor the 15-days-after-forwarding-address deadline is met (whichever is later), your records — DepositsBack.app notice, USPS Certified Mail delivery confirmation, and any response uploaded to your case — document the timeline. Under Connecticut General Statutes § 47a-21, a landlord who violates the security deposit rules can be liable for twice the amount of the security deposit, without any need to prove bad faith; Connecticut small-claims court generally hears disputes up to $5,000. You can review your situation alongside the statute and official state resources, and decide whether to consult a Connecticut attorney or proceed with self-help next steps.
