Connecticut Rent Increase Rules: Caps, Notice Periods & Limits (2026)

How much a landlord can raise rent, and what notice they must give

At a glance

• Rent cap: 康涅狄格无州级租金管制（无上限），但地方 Fair Rent Commission 可审查「harsh and unconscionable」涨租。
• Statewide notice law: Yes — see the notice rules below
• Governing statute: Conn. Gen. Stat. § 7-148b (no state cap)

Who this covers — and who it does not

This page covers rent increases in Connecticut for a residential tenancy — whether there is a cap, and what notice a landlord must give.

It does not cover commercial leases, subsidised housing (which follows federal rules), or any city whose local ordinance differs from the state rule.

Is there a rent cap?

Local rules that override the state rule

Fair Rent Commission（25,000+ 人口市镇强制设立，PA 22-30）可审查「harsh and unconscionable」涨租；受保护租客（62+/残疾，5+ 单元）可诉 Superior Court 挑战（47a-23c）。

Sources and how to verify them

Every figure on this page comes from the official text or a state court opinion, not from a summary. The table below lists each provision used and the date it was last checked.

Statute	Last verified	Source
Conn. Gen. Stat. § 7-148b (no state cap)	2026-10-16	official text ↗
Conn. Gen. Stat. § 47a-4e	2026-10-16	official text ↗
Conn. Gen. Stat. § 7-148b, 47a-23c	2026-10-16	official text ↗

Where the official text and a secondary summary disagree, this page follows the official text and says so. Where a provision admits of more than one reading, that is flagged rather than smoothed over.

When you need a lawyer instead of a tool

A self-help guide is the right starting point for understanding your position. Get legal help if:

• You have received an eviction notice — the timeline is now court-driven
• The dispute involves discrimination, unsafe conditions or retaliation
• Your landlord has filed anything in court already
• You are unsure whether a local ordinance changes the state rule

Local legal aid organisations and tenant unions offer free help for qualifying cases. They are independent of this site — we list them because they are the right place to go, not because they link here.
