| How often | Once every 365 days, counted from the start of the tenancy or the last increase, whichever is later. Rent cannot go up during a fixed-term lease. |
| Notice | Three full tenancy months of written notice for a month-to-month tenancy. A tenancy month starts on the day rent is due. |

The calculator takes the current rent, the date of the last increase, the date the tenant gets the notice and the day rent is due. It finds the earliest date allowed by the waiting rule and by the notice rule, and the increase can start on the later of the two.
Earliest by the waiting rule = date of the last increase (or the start of the tenancy) + 365 daysEarliest by the notice rule = the first rent day after the day the notice arrives + 3 whole rental monthsEarliest start date = the later of the two, moved to a rent daySay the rent is $1,800 a month, due on the 1st. It last went up on December 1, 2025, and the tenant receives the notice on August 15, 2026.
| Step | How | Result |
|---|---|---|
| Earliest by the waiting rule | December 1, 2025 + the waiting period | December 1, 2026 |
| Earliest by the notice rule | Notice received August 15, 2026 | December 1, 2026 |
| Earliest start date | The later of the two | December 1, 2026 |
