Thinking about turning your North Falmouth or Falmouth home into a short-term rental? You want steady income without surprises, especially with coastal rules and seasonal swings. This guide gives you a clear checklist to stay compliant, protect your property, and model returns before you buy or list. Let’s dive in.
Know the rules and taxes
You must register each short-term rental with Massachusetts and obtain a certificate number before hosting. The state room occupancy excise applies to stays of 31 days or less, and returns are filed monthly. Review the 14-day exemption if you rent for 14 days or less and declare it on time. See the state’s requirements on the room occupancy excise and MassTaxConnect registration to set this up correctly.
- Register with the state and get your certificate number. Confirm who will collect and remit taxes if you use a platform. Learn the state process.
- Budget the full tax stack: 5.7% state excise, Falmouth’s local option (confirm current rate), and 2.75% Cape Cod & Islands Water Protection Fund. Some operators may also face a community impact fee. Confirm current local percentages on the DOR local options page.
- Monitor town updates. Falmouth has a Short-Term Rental Working Group exploring local registration and enforcement. Check the town’s STR review page for the latest before you list.
Verify property systems and site risk
Coastal properties perform well when they are safe, code compliant, and resilient. A few checks can make or break your plan, especially on septic and flood risk.
Septic capacity and Title 5
On much of Cape Cod, septic design flow limits your lawful bedrooms and practical occupancy. Pull septic plans, compliance documents, and any deed restrictions before you buy or set your guest count. If records are incomplete or old, schedule a Title 5 inspection. Review the state’s Title 5 regulations.
Flood zone and coastal hazards
Confirm your FEMA flood zone and base flood elevation. In Falmouth, the Floodplain Overlay District references FEMA maps and may impose elevation or construction requirements, especially in velocity zones. Check the zoning overlay to see what applies and whether you need an elevation certificate for insurance. Review Falmouth’s Floodplain Overlay reference.
Conservation and coastal setbacks
If your home is near wetlands, dunes, or marsh, plan for Conservation Commission review for additions or site work. That can affect costs and timelines for improvements like decks or added parking.
Building and safety basics
Make sure smoke and carbon monoxide alarms, egress, electrical, and heat meet state housing standards. Post owner or local emergency contact information and keep it current. Schedule any required inspections before your first booking.
Protect yourself with insurance
Massachusetts requires at least 1,000,000 dollars in liability coverage per short-term rental unless your platform provides equal or greater coverage. Notify your insurer that you operate an STR and confirm coverage in writing, including exclusions. If you rely on platform coverage, get documented limits and consider an STR endorsement or separate policy. See the state law governing STR insurance in Chapter 337.
Plan operations that fit the neighborhood
Clear rules and smooth logistics keep guests happy and neighbors comfortable. On Cape Cod, parking, trash, and noise are the big three.
- Define on-site parking and share a simple parking map in your welcome guide.
- Set trash and recycling schedules and instructions. Use labeled bins and a backup plan for peak season.
- Establish quiet hours and post house rules in plain language. Falmouth is updating noise standards, so review the Proposed Noise Bylaw as you set expectations.
- Post emergency numbers and a local contact who can respond 24/7.
Model revenue and costs in Falmouth
Cape Cod is seasonal. Summer drives a large share of bookings and rates, while shoulder months vary by location and property type. Recent coverage highlights strong summer demand and growing regional inventory, which influences pricing and occupancy. For context, see the Boston Globe’s take on Cape Cod STR seasonality.
Project revenue by month using neighborhood-specific data. Tools show that ADRs and occupancy vary by bedroom count, walkability, and quality. Start with conservative assumptions and verify with a current report for Falmouth on Airbtics, then layer in your exact location and features. Budget for septic maintenance or upgrades, insurance, platform fees, cleaning, management, and offseason reserves. For septic care expectations, review the state’s Title 5 guidance.
Your step-by-step checklist
A) Legal and tax
- Register the property and obtain your state certificate number. Record it in your listings and records. Start with the DOR guide.
- Confirm current tax rates and who remits them. Cross check the state, local option, and Water Protection Fund rates on the local options page.
- Track Falmouth rulemaking. Review the Short-Term Rental Working Group page and recent agendas before you list or buy.
- Review private documents. Check HOA, condo bylaws, and deed restrictions for limits on rental frequency or minimum stays.
B) Site and physical
- Verify Title 5 capacity. Pull septic plans, certificates, and any recorded bedroom limits; schedule an inspection if needed. See Title 5 regulations.
- Check flood status. Confirm FEMA zone, base flood elevation, and whether you have an elevation certificate; review the Floodplain Overlay for local requirements.
- Confirm safety compliance. Test smoke and CO detectors, verify two means of egress, and address electrical or heating issues before hosting.
C) Operations
- Insurance confirmation. Obtain written proof of at least 1,000,000 dollars liability coverage that applies to STR use, or platform documentation with equal limits. Review state requirements.
- Trash, noise, and parking plan. Set schedules, quiet hours, and clear parking rules; reference Falmouth’s Proposed Noise Bylaw in your house rules.
- Local contact. List a 24/7 contact able to respond promptly during guest stays.
D) Financial and market
- Run a conservative revenue model. Use neighborhood-level ADR and occupancy data and test offseason scenarios. Start with Airbtics’ Falmouth snapshot and then refine with local comps.
- Budget realistic expenses. Include management fees, cleaning, insurance, taxes, utilities, septic servicing and potential upgrades, coastal hardening, and reserves. The state’s Title 5 overview helps you plan septic maintenance.
