N1 — Notice of Rent Increase
The only valid way to raise rent on a guideline-covered unit. For 2026 the guideline is 2.1%; for increases taking effect on or after January 1, 2027 it is 1.9%.
⏰ The deadlines
| Notice required | At least 90 days before the increase takes effect |
| Frequency | At most once every 12 months |
🛡️ Defenses & defects to check
- Above the guideline with no LTB order (and unit first occupied before Nov 15, 2018) → you generally do not have to pay the excess
- Less than 90 days' notice → the increase is not valid until properly re-served
- Increase demanded by text/email without the form → not a valid notice
💡 What the pros know
- Careful: paying an illegal increase without disputing it for 12 months can make it your lawful rent. Question it early, in writing.
- Check your increase in seconds with the Rent Increase Checker.
