Harwich, Massachusetts

Harwich requires registration for any property rented for fewer than 90 days, administered by the town’s Building Department, but the program is light-touch with no registration fee and no penalty for non-compliance. Owners self-certify that smoke and carbon-monoxide detectors are working and that the property meets current building codes. Routine inspections are not required and occur only if a complaint is filed. There is no owner-occupancy or primary-residence requirement, no documented cap on rental nights per year, and no zoning overlay restricting STRs across Harwich’s residential villages. As of reporting, compliance was low: the town’s registry held approximately 233 properties versus an estimated 1,114 in the Massachusetts state registry (about 21%). All operators must separately register with the Massachusetts Public Registry of Lodging Operators. The total room occupancy tax for Harwich is 14.45%: 5.7% state excise plus 6.0% local option plus 2.75% Cape Cod and Islands Water Protection Fund. A community impact fee of up to 3% may apply to operators with multiple properties or owner-occupied 2-to-3-unit rentals. Harwich is considered one of the more permissive Cape Cod towns for STR operators, given the absence of fees, caps, and proactive enforcement. Investors should confirm current 2026 rules directly with the town.
