In Connecticut, returning possession of any leased property—commercial or residential—must be handled through the state's judicial system via the Summary Process procedure (C.G.S. § 47a-23).

Despite having broad contractual freedom in their leases, commercial landlords in Connecticut cannot engage in "self-help" evictions. No matter what a lease clause says, a landlord cannot legally change the locks, cut off power, or remove a tenant's inventory without a formal Execution of Eviction authorized by a judge. Doing so exposes the commercial landlord to severe civil liabilities.

1. Establishing Default Based on the Lease

Before initiating a Summary Process, the commercial landlord must establish that the tenant is in fundamental default of the lease. Unlike the residential sector, definitions of default in commercial real estate are established entirely by the contract.

Common commercial defaults include:

• Monetary Default: Failure to pay base rent, common area maintenance (CAM), or real estate tax pass-throughs.
• Non-Monetary (Curable) Default: Failing to maintain required liability insurance, unauthorized structural alterations, or failing to keep specific retail operating hours.
• Lapse of Time: Refusing to vacate the premises upon the natural expiration of the commercial lease term.

2. Delivering the Notice to Quit / Notice to Cure

The first formal step of eviction is delivering a written notice to the tenant. The timeline primarily hinges on the commercial lease agreement.

The Notice to Cure (Pre-Eviction Notice)

Before a formal eviction notice can be served, many commercial leases include a mandatory "Notice to Cure" clause. For example, the lease might state: "Landlord must provide five (5) days' written notice of monetary default before commencing legal action." The landlord must strictly comply with this leased provision.

The Statutory Notice to Quit

Once any lease-mandated cure periods expire unheeded, the landlord must issue a statutory Notice to Quit Possession.

• Under Connecticut law, the statutory default notice period is a 3-Day Notice to Quit.
• The tenant gets three full, clear days to vacate the premises before the landlord can file a lawsuit. (The day the notice is served and the final day to vacate do not count toward the three clear days).

Unlike residential law—which forces a landlord to wait through a strict 9-day rent grace period before issuing the notice—commercial landlords can typically issue the 3-Day Notice the very moment the rent becomes overdue (factoring in any grace period explicitly defined in the lease).

3. Filing the Summons and Complaint

If the 3-day notice period expires and the commercial tenant remains on the premises, the landlord’s attorney files a Summons and Complaint with the local Housing Session of the Superior Court.

1. Service of Process: A state marshal serves the Summons and Complaint to the tenant's business address (or their registered agent).
2. The "Appearance": The commercial tenant has a brief window (usually two days after the "Return Date" listed on the Summons) to file a formal Appearance with the court.

4. Default Judgments, Answers, and Trial

• Failure to Appear: If the commercial tenant doesn't file an Appearance by the deadline, the landlord can immediately file a Motion for Default Judgment for Failure to Appear. If the court grants it, the landlord wins automatically.
• The Answer and Special Defenses: If the tenant does appear, they must file an Answer to the complaint, which may include "Special Defenses" (e.g., arguing the landlord materially breached the lease first by failing to repair structural column damage).
• Trial: If the case cannot be settled through a stipulated agreement or mediation, it proceeds to a trial before a judge. Because commercial cases are primarily contract disputes, they move rapidly through the Summary Process system.

5. Execution of the Eviction

Once the landlord secures a judgment of possession from the judge, there is a mandatory 5-day statutory stay of execution (an appeal window).

After 5 days, the landlord must request a Summary Process Execution for Possession. This document allows a state marshal to physically execute the eviction, removing the commercial tenant and their property under municipal supervision, finally returning possession of the premises to the landlord.
