Connecticut Rental Lease Agreement | Laws

A Connecticut lease agreement is a legal contract entered into between a landlord and a tenant. There are numerous types of lease agreements that cover a range of renting situations for both residential and commercial properties. Although all the forms have different purposes, they all share common attributes such as including terms and conditions that allow the landlord and tenant to establish a relationship that will be fair, civil, and mutually beneficial. Landlords almost always review applicants before accepting an individual for tenancy (see rental application form below). Once they have chosen a prospective tenant, both parties can sit down and examine the lease agreement before signing.
