New Brunswick Tenant Lease Issues: A Complete Guide

Leases & Agreements New Brunswick 5 min read · published March 09, 2026 Flag of New Brunswick

Entering into a lease or rental agreement in New Brunswick gives you important rights and obligations as a tenant. If you're unsure about the rules around deposits, lease renewals, or your duties after signing, understanding the laws can help protect your home. This guide explains New Brunswick lease and agreement issues in clear language, outlining official forms, how to resolve common disputes, and where to seek help if needed.

Leases and Rental Agreements in New Brunswick

Every tenancy in New Brunswick—whether written or verbal—is governed by the Residential Tenancies Act (New Brunswick)[1]. The law covers essentials such as security deposits, maintenance duties, lease renewals, and ending agreements.

Types of Agreements

  • Fixed-term leases: Set for a defined period (e.g., 12 months). Ends on the expiry date unless renewed.
  • Periodic leases: Renew automatically—usually month-to-month—unless a party gives proper notice.
  • Verbal vs. written: Written agreements are highly recommended, but even verbal arrangements are covered by law.
Verbal leases are legally enforceable in New Brunswick, but writing reduces disagreements. When negotiating, request a written summary that lists rent, start date, term, and who handles maintenance. Always keep a copy of the signed agreement.

Security Deposits

Landlords in New Brunswick may request a security deposit—often called a "damage deposit"—but it can't exceed one month's rent. You'll get a receipt and the deposit must be placed in trust.

Ensure you receive a receipt and that the deposit is held in trust. If you don’t, contact the Rentalsman promptly and document the issue in writing.

Key Lease Terms to Review

  • Monthly rent amount and payment due date
  • Maintenance and repair responsibilities
  • Rules about guests, pets, and subletting
  • Procedures for rent increases
  • How the agreement can be ended by either party
Before you sign, confirm who is responsible for ongoing maintenance and how rent increases will be applied. Ask for any pet or guest rules in writing and keep a copy.

After you sign the agreement, review your rights and what steps to take next in What Tenants Need to Know After Signing the Rental Agreement.

What to Do After Signing Your Lease

Once your agreement is signed, both tenants and landlords must follow the rules set out in the lease and New Brunswick law. Always keep a copy of your lease and any deposit receipts.

Common Lease Issues for New Brunswick Tenants

  • Rent Increases: New Brunswick does not have rent control, but landlords must provide at least three months’ written notice before increasing rent.
  • Early Termination: Tenants need to give written notice if they wish to end a monthly tenancy (typically one month's notice). For fixed-term leases, ending early may require landlord consent or valid legal grounds.
  • Maintenance and Repairs: Landlords are responsible for keeping the property in a good state of repair. Tenants must keep the rental clean and report problems promptly.
  • Lease Renewals: If a fixed-term lease expires, it automatically converts to a month-to-month tenancy unless a new contract is signed or valid notice is provided.
  • Deposits: Security/damage deposits are regulated and must be returned, with interest, at the end of tenancy if no damage has occurred, excluding normal wear and tear.
If your landlord is not meeting their responsibilities, communicate in writing first. Save all correspondence to support your position if a dispute arises.

Essential Forms for Tenants in New Brunswick
