Moving to Barnstable County, MA?

Barnstable County (Cape Cod) does NOT issue short-term rental permits or licenses. Under the Massachusetts Constitution, the Home Rule Amendment (Article 89), and Chapter 337 of the Acts of 2018 (codified at MGL c.64G, c.62C s.67, and c.64G s.14), STR registration and licensing is split between two layers: (1) statewide mandatory operator registration with the Massachusetts Department of Revenue (DOR), required for every operator regardless of rental volume since July 1, 2019; and (2) town-level rental certificates and zoning rules administered by each of Cape Cod's 15 towns (Barnstable, Bourne, Brewster, Chatham, Dennis, Eastham, Falmouth, Harwich, Mashpee, Orleans, Provincetown, Sandwich, Truro, Wellfleet, Yarmouth). Barnstable County's only direct STR-related role is the 2.75% Cape Cod and Islands Water Protection Fund excise (MGL c.64G s.3C), which is collected by DOR on every Cape Cod STR booking and funds wastewater infrastructure regionally. The combined state, county, and local tax in most Cape towns is 14.45%; Provincetown adds a 3% community impact fee on professionally-managed units for a 17.45% total.

Massachusetts is the only U.S. state with a complete ban on consumer fireworks. Under MGL Chapter 148, Section 39, no person may sell, possess, or use any fireworks in Barnstable County, including sparklers, firecrackers, Roman candles, bottle rockets, and party poppers. Only licensed pyrotechnicians with a State Fire Marshal permit and local fire-chief approval may conduct public displays. Cape Cod National Seashore separately prohibits fireworks on all federal beach lands.

Barnstable County (Cape Cod) does not enforce its own pool barrier ordinance; pool fencing across the county's 15 towns (Barnstable, Bourne, Brewster, Chatham, Dennis, Eastham, Falmouth, Harwich, Mashpee, Orleans, Provincetown, Sandwich, Truro, Wellfleet, Yarmouth) is regulated through the Massachusetts State Building Code 780 CMR, which adopts the International Swimming Pool and Spa Code (ISPSC) requiring a 48-inch barrier for residential pools, plus MGL c.140 §206 and 105 CMR 435 for public/semipublic pools requiring a 6-foot fence. Construction permits and inspections are issued by each town's building department; public pools are licensed and inspected by the local board of health.

Barnstable County does not regulate accessory dwelling units (ADUs) at the county level. Massachusetts is a home-rule state under Article 89 of the Massachusetts Constitution, and zoning authority belongs to each city or town under MGL c. 40A. As of February 2, 2025, the statewide Affordable Homes Act (Chapter 150 of the Acts of 2024, codified at MGL c. 40A, s.3, paragraph 11) preempts local ADU bans: ADUs up to 900 square feet are allowed by right in single-family zoning districts in every Barnstable County town - Barnstable, Bourne, Brewster, Chatham, Dennis, Eastham, Falmouth, Harwich, Mashpee, Orleans, Provincetown, Sandwich, Truro, Wellfleet, and Yarmouth. Towns may regulate setbacks, height, bulk, short-term-rental use of an ADU, and impose site-plan review, but cannot require owner-occupancy or a discretionary special permit for a protected ADU. The Cape Cod Commission, established under the Cape Cod Commission Act (Chapter 716 of the Acts of 1989), is the regional planning agency for Barnstable County but does not approve individual ADU applications - its Development of Regional Impact (DRI) review is triggered at 30 or more residential units, far above any single ADU.

Barnstable County (Cape Cod) is a low-lying coastal peninsula with extensive Atlantic, Cape Cod Bay, and Nantucket/Vineyard Sound exposure to V/VE wave-action zones, AE riverine and tidal floodplains, and accelerating sea-level rise. FEMA Flood Insurance Rate Maps (FIRMs) for all 15 Cape Cod towns became effective July 16, 2014. Flood damage prevention is enforced at the town level under the 9th Edition Massachusetts State Building Code 780 CMR (R322 / Appendix G), which incorporates ASCE 24-14 and requires Design Flood Elevation = Base Flood Elevation + 3 feet of freeboard in V Zones and Coastal A Zones. The Massachusetts Wetlands Protection Act (M.G.L. c. 131 sec. 40) and 310 CMR 10.00 add a parallel layer of permitting through each town's Conservation Commission for any work in coastal banks, dunes, barrier beaches, salt marshes, or land subject to coastal storm flowage. The Cape Cod Commission's 2021 Model Coastal Resilience Bylaw and 2024 Model Floodplain Zoning Bylaw push higher standards using Massachusetts Coast Flood Risk Model (MC-FRM) projections for 2050 and 2070.
