Quick Answer: Maine's Short-Term Rental Landscape
Maine's short-term rental (STR) market balances a booming tourism economy with housing stock pressure. With a median listing price of $432,425 (FRED/Realtor.com, March 2026) and 741,803 total housing units statewide (U.S. Census ACS 5-Year Estimates, 2022), competition between vacation rentals and long-term housing is evident. This prompts local government responses.
Every Maine STR owner needs to know upfront:
State-level obligations are limited but mandatory. Maine imposes a lodging tax on short-term rentals. This tax is collected and remitted to Maine Revenue Services. Basic fire and life-safety codes also apply statewide. Beyond these, the state largely steps back.
Local ordinances carry the real weight. Portland, Bar Harbor, Kennebunkport, and dozens of other municipalities have enacted their own permit requirements, zoning restrictions, occupancy caps, and operational rules. These vary dramatically from town to town.
Regulations are evolving rapidly. Popular coastal and lakefront communities have amended their STR ordinances multiple times in recent years. Rules from 18 months ago may no longer apply.
Confirm state tax obligations first, then contact your municipal planning or code enforcement office.
