Overview of South Portland Rent Control
The City of South Portland, Maine has a rent stabilization ordinance administered through the South Portland Rent Board.
Because current public sources conflict or do not clearly confirm a clean current annual percentage, RentCheckMe does not encode a specific South Portland cap figure. Tenants and landlords should verify the current allowable increase with the Rent Board before acting.
Who Is Covered?
Coverage can turn on ordinance definitions and building facts. The calculator models the local rule conservatively by treating buildings constructed after 1983 as exempt, consistent with the calculator rule data.
Newer construction – buildings constructed after 1983 are modeled as exempt
Owner-occupied buildings with no more than 5 units
Units regulated by other government entities
Temporarily exempt units through the petition process
Rent Increase Limits
RentCheckMe links to the official Rent Board instead of publishing an unverified numeric cap. Official or secondary sources have described conflicting CPI/percentage or flat-cap approaches, so this page avoids stating a percentage unless it can be confirmed from the City.
