Form N1: Notice of Rent Increase

What this form is generally used for, common scenarios and the key timing concepts. Always download the current form and instructions from the Landlord and Tenant Board.

The N1 is generally used to give a tenant notice of a rent increase for a rent-controlled unit.
It must be given at least 90 days before the increase takes effect.
At least 12 months must have passed since the tenancy started or since the last increase.
The increase generally can't exceed the guideline for the year it takes effect, unless the Board has approved more.

What the N1 is for

Form N1 is the Landlord and Tenant Board's notice of rent increase for most rent-controlled units. It tells the tenant the current rent, the new rent and the date the increase takes effect.

Common scenarios

A yearly guideline increase for a long-term tenant.
An increase that includes an above-guideline amount the Board has already approved.
Not used for exempt units. Those generally use Form N2.

Timing concepts

Count at least 90 full days between the date the notice is given and the effective date. Add any extra days the service method requires (for example, mail). The effective date must also be at least 12 months after the last increase or the start of the tenancy.

If a notice is late or the math is wrong, the increase may not be lawful. The rent increase calculator shows the guideline amount and planning dates.

Common mistakes

Using the guideline for the year the notice is served instead of the year the increase takes effect.
Giving fewer than 90 days' notice once service time is counted.
Increasing rent less than 12 months after the last increase.
Using an outdated version of the form.

Common questions

Does the tenant need to sign the N1?

No. A properly given guideline increase doesn't need the tenant's agreement.

Can I give an N1 by email?

Only if the tenant has agreed in writing to receive notices by email.

What if I made a mistake on the N1?

Generally, serve a corrected notice that still meets the 90-day requirement from the new service date.

Is the N1 used for new tenants?

No. Rent for a new tenancy is set by agreement. The N1 applies to increases during a tenancy.

Where do I get the current N1?

Download it from the Landlord and Tenant Board forms page.
