Leases & Rental Agreements: New Brunswick Tenant FAQ

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

Are you a tenant in New Brunswick looking to better understand leases and rental agreements? The laws and rules can feel confusing, but knowing your rights makes renting less stressful. This guide answers the most frequent questions about leases, deposits, and tenant obligations under New Brunswick’s rental laws.

Understanding Leases & Rental Agreements in New Brunswick

In New Brunswick, rental agreements are governed by the Residential Tenancies Act. This law sets out what landlords and tenants must do, what’s allowed in a lease, and how to resolve disagreements.

What is a Lease?

A lease, sometimes called a rental agreement, is a legal contract between a landlord and tenant. In New Brunswick, leases can be written or, rarely, verbal (but written is strongly recommended). Most leases are for a fixed term (like 12 months), but month-to-month agreements are also common.

  • Written agreements are best: They set out the rent, who pays for utilities, when rent is due, and the start/end date.
  • Verbal agreements are legal, but much harder to prove if there’s a dispute.
  • Every lease must include the standard terms required by law. Any terms that contradict the Residential Tenancies Act are not valid.

Security Deposits

Most landlords ask for a deposit before you move in. In New Brunswick, this is called a “security deposit.” The maximum deposit is equal to one month’s rent. It must be paid directly to the Office of the Rentalsman (not to the landlord), who will hold it until you move out.

In New Brunswick, the security deposit cannot exceed one month's rent and is held by the Rentalsman until move-out. Keep a dated move-in inspection and receipt of payment for your records.

Before You Move In

  • Read the entire lease, including any attachments.
  • Ask for a copy of the signed agreement.
  • Inspect the unit for any damage and note it in writing.
Create a move-in checklist, photograph any damage, and note dates. Share copies with the landlord and keep originals for move-out reference.

Key Lease Terms to Look For

  • Rent amount and when it’s due
  • Who pays for heat, electricity, water, or other fees
  • Duration (fixed term or month-to-month)
  • Notice required to end the lease
  • Any special rules about pets, guests, or smoking

Rent Increases

Landlords can increase rent, but must provide proper written notice—usually at least three months in advance. There’s no legal limit on the amount of increase, but it must be reasonable, and tenants can challenge increases they believe are unfair. See the New Brunswick Office of the Rentalsman for details on challenging rent increases.

There is no statutory cap on rent increases in New Brunswick; increases must be reasonable. If you think a hike is unfair, file a challenge with the Rentalsman using Form 5 and request a review.

Ending or Renewing a Lease

You can end your rental agreement by giving written notice, but the amount of notice required depends on the type of lease:

  • Month-to-month: At least one month’s written notice
  • Fixed term (e.g., one year): Lease ends on its expiry date. If you don't give notice, it may automatically renew month-to-month.

If you need to leave before your lease ends, special rules apply. For a smooth exit, review our tips in How to Properly End Your Rental Agreement as a Tenant. For more, visit Lease Renewals: What Tenants Should Know About Their Rights.

If your lease auto-renews, check renewal terms early and discuss any changes in writing before expiry to avoid surprises.
