- Written notice on the proper LTB form (Form N1 for most units) at least 90 days before the increase.
- A notice sent by mail counts as served on the fifth day after mailing.
- The guideline for the year the increase takes effect sets the maximum; it is capped at 2.5%.
- Units first occupied for residential purposes after November 15, 2018 are not limited by the guideline, but still need 90 days' written notice.
