A beautiful property can still be a bad short-term-rental purchase. Before estimating revenue, confirm that the intended use is lawful, licensable, insurable, financeable, and durable under conservative operating assumptions.
Decide the intended use before choosing the property
The first question is no longer simply, “What could it earn?” It is, “Can it legally operate the way I intend?” Bangor and Scarborough do not use the same definition, license structure, zoning framework, or timing. A property that works under one municipality's rules may not work under the other's.
The rules are only one layer. A municipal approval does not override a deed restriction, condominium rule, mortgage term, insurance exclusion, septic limit, or other law. Treat zoning and licensing as the beginning of diligence, then test the complete operating plan.
The two municipalities start with different definitions
Bangor generally treats compensated stays of fewer than 30 consecutive days in a dwelling, dwelling unit, accessory dwelling unit, or one or two bedrooms as short-term rentals under its current chapter. A city license is required now. A hosted rental is tied to the owner or operator's primary residence; a non-hosted rental is not.
Scarborough's 2026 ordinance generally uses stays of fewer than 28 consecutive days in a legally existing residential dwelling. A dwelling rented no more than twice in a calendar year and for fewer than 14 total days falls outside that chapter's definition. Registration applications are due by December 31, 2026, and beginning January 1, 2027, an STR may not be advertised, operated, or rented without registration.
Bangor: licensing, caps, and building limits
Bangor limits non-hosted licenses citywide to 1% of the dwelling units existing each April 1, issued first-come, first-served. A person or entity may hold no more than five STR units in a license year. In many buildings with three or more units under common ownership or unified management, no more than 50% of the units may be short-term rentals. A 2026 amendment adds a separate rule for certain tiny-home and manufactured-home parks under shared ownership.
The license year runs from May 31 to May 31. Renewal is due at least 30 days before expiration. A late renewal is treated as a new application, which matters particularly for a non-hosted unit subject to the cap. Licenses do not transfer with the property and do not create a vested property right.
Inspection
A fire and life-safety inspection is required before issuance, with reinspection generally every three years on renewal.
Emergency response
The application requires a 24/7 natural-person contact capable of responding at the property within 60 minutes.
Insurance
Coverage must expressly permit short-term-rental use; ordinary homeowner coverage should not be assumed sufficient.
Current fees
As of August 31, 2026, Bangor lists $250 for a new license or renewal requiring inspection, $100 for renewal without inspection, and $100 for each additional inspection.
Scarborough: zoning and the coastal overlay matter
Scarborough's treatment depends heavily on the parcel's zoning and whether the rental is owner-occupied. Outside the Coastal Beach Overlay, owner-occupied STRs generally require a special exception in residential districts and are allowed by right in Village and Commercial districts. Non-owner-occupied STRs are generally prohibited in residential districts outside the overlay, require a special exception in Village and Running Hill districts, and are allowed by right in Commercial districts. Separate rules apply inside the Coastal Beach Overlay.
Do not rely on a neighborhood name to determine overlay status. Use the official map or parcel lookup and confirm the result with the Town. Also note the unusually important accessory-dwelling-unit rule: STR use is not permitted in an ADU—or in the principal dwelling on the same lot as an ADU—when the ADU was approved under the cited ordinance section.
Registration
Registration is annual, belongs to the owner rather than a renter, and is not transferable to a buyer.
Safety
The ordinance addresses smoke, carbon-monoxide, fuel-gas detection where applicable, and a portable fire extinguisher.
Parking
Guests and tenants may not use on-street parking under the referenced Town ordinance; confirm adequate legal off-street capacity.
Current fee
Scarborough's official fee schedule lists a $200 registration fee as of August 31, 2026.
Do not assume an existing rental is permanently grandfathered
Scarborough created a fact-specific transitional special-exception process for certain existing 2025 operators who document qualifying rental activity and register by December 31, 2026. If an otherwise qualifying use is located in a district where STRs are not allowed, the temporary ability to register may end December 31, 2027.
That is not a general promise that every old rental can continue. A buyer should confirm the operator's evidence, zoning, registration history, deadlines, and whether any right survives a transfer. Bangor licenses are likewise non-transferable, so the seller's license should never be treated as the buyer's approval.
The six numbers I would test before recommending an offer
Lawful, available use
Confirm zoning, classification, license or registration availability, occupancy, parking, septic capacity, and any private restrictions in writing where appropriate.
Conservative revenue
Use supportable nightly rates, realistic occupied nights, seasonal variation, platform costs, and downtime—not the seller's best month multiplied by twelve.
Complete operating cost
Include heat, electricity, internet, water, sewer or septic, insurance, snow, cleaning, supplies, management, repairs, taxes, and municipal fees.
Immediate capital work
Price life-safety upgrades, furniture, roof, heating, drainage, well, septic, parking, and deferred maintenance before calling the property turnkey.
Financing and reserves
Confirm the lender understands the intended use, then preserve enough cash for seasonality, repairs, and a slower launch than projected.
A second exit
Decide whether the property still works as a long-term rental, owner-occupied home, or resale if rules, travel demand, insurance, or personal plans change.
A pre-offer checklist
Before writing, obtain municipal confirmation of the parcel's zoning and current use, license or registration status, applicable cap or exception, safety requirements, and outstanding violations. Review the deed, association or condominium documents, insurance indication, loan terms, utility history, water and wastewater systems, parking, and realistic comparable revenue. Confirm the current ordinance directly rather than relying on an older listing description or social-media summary.
There is no blanket winner between Bangor and Scarborough. The better opportunity is the one where the lawful use, acquisition basis, operating burden, financing, and alternate exit all work together.
