Cal. Civ. Code § 8-68f-13
Provision for Modifications
Operative Text
The lease shall provide that any modification thereto shall be mutually agreed upon, in writing, and incorporated into the original lease, except a waiver of such requirement may be made by mutual agreement or by course of conduct.
Under Conn. Agencies Regs. § 8-68f-13, any change to a lease must be agreed to by both parties, put in writing, and formally added to the original lease document. The rule does carve out an exception: the written-modification requirement itself can be set aside if both parties mutually agree to waive it or if their ongoing behavior demonstrates a shared understanding that the lease terms have changed. This provision establishes a default standard of formality for lease amendments while preserving flexibility when both sides act consistently with a different arrangement.
Plain English — not legal advice.
Under Conn. Agencies Regs. § 8-68f-13, compliant operators generally document every lease change in a signed written addendum that is attached to or incorporated into the original lease. Keeping a clear paper trail of all modifications helps demonstrate that any changes were mutually agreed upon and properly recorded. Operators should also be aware that consistent patterns of conduct—such as repeatedly accepting a different rent amount or allowing a use not originally permitted—can be interpreted as a waiver of the written-modification requirement, even without a formal document.

Conn. Agencies Regs. § 8-68f-13 establishes that tenants have a right to expect lease changes to be documented in writing and mutually agreed upon before they take effect. If a landlord attempts to enforce an oral or unilateral modification that was never put in writing or incorporated into the lease, a tenant may be able to raise the absence of a proper written amendment as a defense in a dispute. Tenants who believe this provision has been violated can consult a local tenant-rights organization or a Connecticut legal aid office to understand the options available to them.
