Is Castine, Maine Good for Airbnb Investment?

To start an Airbnb in Castine, Maine, begin by researching local zoning laws and short-term rental regulations through the Castine Town Office, as Maine municipalities have varying requirements and Castine may require specific permits or registration for vacation rentals. Contact the town clerk at (207) 326-4548 to understand any occupancy limits, parking requirements, and tax obligations including Maine's 9% lodging tax. Find a suitable property by working with local real estate agents familiar with Castine's historic district regulations, as many properties fall under historic preservation guidelines that may restrict modifications. Once you secure a property, obtain necessary permits including a business license from the town and ensure compliance with Maine's life safety codes, which may require smoke detectors, carbon monoxide detectors, and proper egress windows. Furnish the property with coastal Maine-themed decor, quality linens, and essential amenities while ensuring it meets accessibility standards if applicable. Create your Airbnb listing with professional photos highlighting Castine's maritime charm and proximity to the Maine Maritime Academy, setting competitive rates based on seasonal demand (higher in summer months). For ongoing management, establish relationships with local cleaning services, maintenance contractors, and consider property management companies in the greater Penobscot Bay area if you're not local, while maintaining guest communication and ensuring compliance with ongoing tax reporting requirements to both the state of Maine and Hancock County.

To identify profitable short-term rental properties in Castine, Maine, focus on waterfront or water-view locations within walking distance of the Maine Maritime Academy and historic downtown area, as these command premium rates of $200-400 per night during peak summer months. Target 2-4 bedroom historic homes or cottages built before 1900 with original character features, updated kitchens and bathrooms, outdoor spaces, and parking, as guests pay 20-30% more for authentic Maine charm. Analyze comparable properties on Airbnb and VRBO showing average daily rates of $150-350 depending on season, with occupancy rates typically 60-75% May through October but dropping to 20-30% in winter months. Research shows limited competition with only 15-25 active STR properties in Castine proper, creating opportunity but requiring careful positioning against established operators like Pentagöet Inn and Castine Harbor Lodge. Utilize AirDNA for market data, STR Helper for performance tracking, and local resources including Castine Town Office for permitting requirements, Hancock County Registry of Deeds for property research, and Maine Maritime Academy event calendar to identify peak demand periods that can drive rates above $500 per night during graduation and special events.

To obtain an Airbnb/STR permit in Castine, Maine, you must first contact the Castine Town Office at 67 Court Street to submit an application for a Short-Term Rental License, which typically requires a completed application form, proof of property ownership or lease agreement, a site plan showing parking and egress routes, certificate of occupancy, and current homeowner's insurance policy with liability coverage of at least $300,000. The application fee is approximately $150-200 annually, with additional fees for inspections around $75-100. Required documents also include a septic system inspection certificate if applicable, fire safety compliance documentation, and a waste management plan detailing trash collection arrangements. Castine specifically requires STR properties to maintain adequate off-street parking (minimum 2 spaces), comply with the town's noise ordinance with quiet hours from 9 PM to 7 AM, and limit occupancy to no more than 2 people per bedroom plus 2 additional guests. The approval timeline typically takes 4-6 weeks from submission of a complete application, including time for the required health and safety inspection by the Code Enforcement Officer. Properties must also register with the Maine Revenue Service for lodging tax purposes and display the registration number in all advertising, while maintaining a local contact person available 24/7 for emergency situations and guest issues.
