Connecticut Commercial Required Disclosures
Generally, the commercial real estate market operates on the doctrine of caveat emptor ("let the buyer/lessee beware"). Under the Connecticut General Statutes (C.G.S.), which have served as the foundation of property law since 1818, commercial tenants are viewed as sophisticated business entities, and Connecticut state law mandates very few specific consumer-level disclosures for commercial property leases.
The heavy lifting of due diligence falls almost entirely on the commercial tenant before they sign the lease. However, there is one massive exception: Environmental Liability.
Under Connecticut law, environmental disclosures for commercial properties are no longer governed by the Connecticut Transfer Act (C.G.S. § 22a-134 et seq.). The Transfer Act sunsetted on March 1, 2026, and has been replaced by the Release-Based Clean Up Regulations (RBCRs).
Key provisions of the Release-Based Clean Up Regulations (RBCRs) include:
- Trigger for Obligations: Environmental investigation and remediation obligations are now triggered by the discovery of actual environmental conditions (releases) to the land and waters of the state, rather than by real estate transfers or the property meeting the definition of an "Establishment."
- Reporting Requirement: A release must be reported, investigated, and remediated once it is discovered, regardless of whether the property is an "establishment" and independent of any transfer.
- Applicability: The RBCRs apply to all property in the state (subject to exemptions) rather than being limited to a specific subset of commercial and industrial properties.
- Responsible Parties: The reporting requirement applies to the owner and anyone who controls the parcel, as well as the person or entity creating the release.
- Scope of Investigation: The RBCRs track individual releases and do not necessarily require site-wide investigations, which was a characteristic of the former Transfer Act.
While not legally mandated by the state for leasing, commercial tenants are still strongly advised to conduct a Phase I Environmental Site Assessment (ESA) during their due diligence. This practice helps establish a baseline defense against potential environmental liability and is heavily demanded by banking lenders. Landlords who conceal known historical contamination may still face significant liability under common law fraud and federal CERCLA (Superfund) laws. See our Connecticut Commercial Lease Guide for incorporating these protective clauses.
Official Law Citation: Statutory authority is derived from the Release-Based Clean Up Regulations (RBCRs) and the Real Estate Brokerage Disclosure requirements under C.G.S. § 20-325d.
Brokerage Agency Disclosures
If the commercial property is being leased with the assistance of licensed real estate agents or brokers, C.G.S. § 20-325d requires the agents to disclose whom they represent early in the transaction.
- A broker representing the landlord must disclose this relationship to the prospective tenant.
- Dual agency (holding a fiduciary duty to both the landlord and tenant) must be explicitly disclosed in writing and consented to by both parties per C.G.S. § 20-325g.

Frequently Asked Questions
▶What are the Connecticut landlord-tenant laws every property owner should know?
Connecticut landlord-tenant law is extensively regulated by the state, primarily under Title 47a of the Connecticut General Statutes. The state places significant emphasis on tenant protections, particularly regarding grace periods, security deposit handling, and the rights of elderly or disabled renters. This guide covers the essential compliance requirements for property owners and landlords.
Read the complete guide▶What is the Connecticut eviction process and how long does it take?
The Connecticut eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in Connecticut. The full court process varies but typically takes several weeks.
Read the complete guide▶What are the Connecticut security deposit rules and return deadlines?
Connecticut has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
Read the complete guide▶What are the Connecticut rent increase laws and caps for landlords?
Connecticut has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide proper written notice before an increase takes effect. Check whether Connecticut has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in Connecticut?
Connecticut has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee. Late fee provisions must be stated in the lease agreement, and fees must be reasonable. Check Connecticut state law and any applicable local ordinances for the exact grace period and late fee limits that apply to your rental property.
Read the complete guide▶What disclosures must Connecticut landlords provide to tenants?
Connecticut landlords must provide certain disclosures to tenants before or at the time of lease signing. Common required disclosures include lead-based paint hazards (for pre-1978 buildings, a federal requirement), the identity of the landlord or property manager, and any known material defects in the property. Additional state-specific disclosures may include flood risk, mold hazards, and environmental conditions.
Read the complete guide▶What are the Connecticut lease requirements for rental properties?
Connecticut recognizes both written and oral leases, though written leases are strongly recommended for terms longer than one year. Lease agreements should include the rent amount, payment due date, security deposit terms, maintenance responsibilities, and rules regarding entry, pets, and subletting. Certain lease clauses that waive tenant statutory rights may be void and unenforceable under Connecticut law.
Read the complete guide▶What are Connecticut landlord maintenance obligations and habitability standards?
Connecticut landlords must maintain rental properties in a condition that is fit for habitation and complies with applicable building, housing, and health codes. This includes maintaining structural integrity, plumbing, heating and cooling systems, electrical systems, and pest control. Tenants typically have the right to request repairs in writing, and if repairs are not made within a reasonable time, tenants may have legal remedies available.
