Portland's ordinance ties the annual allowance to the Consumer Price Index and the city Rent Board publishes it; the state floor still applies (45 days' notice, 75 if the increase tops 10%). We route Portland cases to the Board's published allowance rather than print a percentage from memory.
Portland’s ordinance ties its annual rent allowance to the Consumer Price Index and the city Rent Board publishes the figure; long-term rentals in covered buildings (generally 6+ units, with exemptions) work from that published allowance rather than a number any website can carry in its head. We route Portland cases to the Board’s current allowance instead of printing a percentage from memory — the honest answer on a number that resets.
Underneath the ordinance, the Maine floor still applies to everyone: 45 days’ notice for an increase, 75 days when the increase tops 10% — the size-tiered notice rule almost nobody outside Maine knows exists.
