New Brunswick rent increase calculator (3% cap, six months' notice)
Work out the most a New Brunswick landlord can raise rent under the 3% cap, and the dates that matter: the day the tenant must receive written notice (six months before), whether the first 12 months of the tenancy (or 12 months since the last increase) have passed, and the earliest date an increase could take effect if notice is given today.

New Brunswick rent increase cap by year
| Year | Cap | Example on $1,500/month |
|---|---|---|
| 2027 | 3.0% | +$45.00 = $1,545.00 |
| 2026 | 3.0% | +$45.00 = $1,545.00 |
The 3% is a maximum, not a required increase. It is written into the Residential Tenancies Act, which also requires the New Brunswick Housing Corporation to review the maximum every year, so the figure is subject to annual review (s.11.14). The 2027 row shows 3% because that is what the Act said when we checked it; check gnb.ca before you serve notice. No figure is shown for 2028 or later.
Why the dates matter more than the percentage
The gnb.ca page has its own simple calculator for the 3% amount. What catches landlords out is the timing: six months' notice is long, so an increase you want for 1 June must be in the tenant's hands by the end of November. This calculator gives you the notice-by date, checks the 12-month rules, and tells you the earliest effective date if you serve notice today.
The rules this calculator uses
From the Residential Tenancies Act (SNB, c. R-10.2), General Regulation 82-218 and the Government of New Brunswick's rent increase guidance. Sources checked: 2026-11-10.
- s.11.12(1): "a landlord shall not increase the rent by more than 3% effective at any time on or after February 1, 2025." s.11.12(2): a notice for more than 3% "shall be deemed to be a notice of increase in rent of 3%."
- s.11.14: the New Brunswick Housing Corporation "shall (a) perform an annual review of the maximum rent increase". The 3% can change.
- Regulation 82-218, s.11.1: "the landlord shall not increase the rent unless the landlord gives the tenant six months notice."
- s.11.1(2): the notice of the increase must be "a document separate from any other notice or receipt".
- s.11.1(2.01): "Except when a landlord and tenant have agreed in writing otherwise, a landlord referred to in subsection (2) shall not increase the rent (a) in the first consecutive 12-month period of a tenancy agreement, and (b) more than once in any other consecutive 12-month period of a tenancy agreement."
- s.11.1(2.02): the tenant may apply for a review "within 60 days after the receipt of the notice".
- Above 3%: s.11.13 lets the landlord apply to a residential tenancies officer. Regulation 82-218 s.11.12 allows approval where "capital expenditures for renovations have been incurred", and s.11.12(3) sets "the upper limit to a rent increase is 9 %." gnb.ca: "Landlords must apply for permission to serve a notice of rent increase above the 3% cap, up to 9%, for justified capital expenditures for renovations of units."
- gnb.ca: "Landlords are not permitted to increase rent by more than 3% every 12 months. Under the Residential Tenancies Act, landlords must provide tenants with six months' written notice before implementing a rent increase. Rent can only be increased once every 12 months and not within the first 12 months of the tenancy."
How the dates are counted
- Maximum increase = rent × 3%, rounded down to the cent, so it never goes over the cap. The year is the year the increase takes effect.
- Notice-by date = the day before the same date six months earlier (for example, an increase on 1 December 2026 needs the notice received by 31 May 2026). This is the cautious reading; no extra time is added for how the notice is served.
- 12-month date = the same day one year after the last increase, or after the tenancy started if the rent has never been increased (29 February rolls forward to 1 March). The calculator flags an effective date before it.
- Earliest effective date = the later of the 12-month date and the first date that still allows six months' notice if the tenant receives it today.
- The six months applies to every tenancy type under the current regulation (weekly, monthly and fixed-term).
The notice itself
The Act requires the notice of increase to be a separate document. The gnb.ca rent increase page lists what it should contain (including the tenant's name, the unit address, the current rent and the rent after the increase) and is the place to check for the current requirements. This calculator gives you the amounts and dates; it does not write or replace the notice.
This is arithmetic and calendar counting only, not legal advice. For a specific tenancy, check the gnb.ca guidance above or ask the province.
Keeping track of renewals and notice dates
If you manage several units, a paid spreadsheet by Kyle Falk (Lease & Renewal Tracker) lists every lease with its renewal and notice dates in one place. The Small Landlord Records Bundle includes it with the other landlord record sheets. This calculator stays free either way.
