As a tenant in New Brunswick, you might wonder if your landlord can change the lease rules after you've signed your rental agreement. This question is important because your lease sets the terms for your home, including rights, responsibilities, and protection from unexpected changes. Understanding your rights under New Brunswick's residential tenancy laws can help keep your tenancy secure and stress-free.
Who Regulates Tenancy Agreements in New Brunswick?
In New Brunswick, the Residential Tenancies Tribunal administers and enforces the laws about residential tenancies. The key legislation is the Residential Tenancies Act1 (RTA). All rental agreements—whether written or verbal—are covered by this law.
Are Lease Terms Set in Stone After Signing?
Generally, once you and your landlord sign a lease (often called a 'tenancy agreement'), the terms are legally binding. This includes:
- The monthly rent amount
- Duration of the tenancy
- Who is responsible for utilities or maintenance
- Rules about pets, smoking, or guests
Neither party can change these core terms unilaterally during the fixed term of the lease.
Can Landlords Add or Change Rules During a Lease?
During a fixed-term lease: Landlords cannot change the main rules or conditions until the agreement ends, unless the tenant agrees to the changes in writing. This includes changes about rent, pet policies, or other major terms. Even for smaller rule adjustments (like new building policies or amenities), written consent from the tenant is required unless the lease already allows for such changes.
If your landlord is pressuring you to accept new rules, you do not have to sign or agree to changes unless you want to.
Tip: Always get any agreement about rule changes in writing and keep a copy for your records.
What About Rule Changes When Renewing or After a Lease Ends?
When a lease ends and becomes a month-to-month tenancy, or is up for renewal, landlords may propose new rules or changes. They must give you proper advance written notice—usually at least three months—if the change affects rent or services, or as required by the type of rule being changed2.
