DP-3 (Dwelling Fire) is the standard landlord policy form, covering the structure on an open-perils basis. Landlords also need liability coverage (often $300K–$1M) and Loss of Rents (typically 12 months). Standard homeowners policies do NOT cover rental properties.
Maine's rental market is modest in size but anchored by Portland — the state's largest city and a booming destination for remote workers relocating from Boston and New York. Augusta, Bangor, and Lewiston-Auburn provide additional urban rental markets. Maine's coastal economy generates a disproportionately large vacation rental market relative to the state's population — Bar Harbor, the Kennebunk/Kennebunkport area, Boothbay Harbor, and Old Orchard Beach are major STR destinations attracting summer visitors. The state's cold winters, older housing stock (many properties date to the early 20th century), and significant wildfire risk in dry summers all drive insurance considerations.
Maine landlords should always choose DP-3 open-perils coverage given the state's diverse weather exposure — nor'easters, ice storms, and occasional hurricane remnants can all cause significant property damage. Coastal properties face wind and flooding risks that often require endorsements beyond the standard DP-3 base policy. Maine's older housing stock means replacement cost coverage is particularly important — actual cash value settlements on a 1920s-era property can leave a landlord severely underfunded for rebuilding. Portland STR hosts must register with the city and comply with ordinance requirements; standard DP-3 policies don't cover STR use. Loss-of-rents coverage is important given Maine's 45-day notice requirement for lease termination, which can extend vacancy periods.
A DP-3 dwelling fire policy is the standard landlord form. Unlike an HO-3, it covers the building structure and landlord-owned contents (appliances, lawn equipment) — not the tenant's personal belongings. Tenants must carry their own renters insurance. DP-3 also includes loss of rents coverage (typically 12 months) if a covered loss makes the unit uninhabitable.
Standard DP-3 policies often exclude or limit short-term rental (Airbnb/VRBO) use. Most landlord carriers either require an endorsement, a separate STR policy, or a commercial dwelling policy. Airbnb's "AirCover" host protection is NOT a substitute for your own policy — it has many exclusions and lower limits.

💡 Maine Pro Tip
Maine landlords typically pay $1,050–$1,650/year for a DP-3 policy on a standard rental. Portland single-family rentals average $1,200–$1,800. Coastal properties in Kennebunkport or Bar Harbor that see heavy summer traffic may require specialized vacation rental coverage costing $1,500–$3,000+ when wind and liability endorsements are included.
No — standard landlord policies exclude STR activity. Portland STR operators must also register with the city. Coastal vacation rental property owners throughout Maine need a dedicated vacation rental or commercial landlord endorsement. Bar Harbor and Acadia-area properties during peak summer season carry significant liability exposure that makes proper STR coverage especially important.
Maine has no state law requiring landlord insurance. Mortgage lenders impose their own requirements. Maine's 45-day no-cause termination notice requirement means landlords can face extended vacancy periods — making loss-of-rents coverage a practical necessity beyond just property protection.
