Short-term rentals
Short-term rentals allowed with local rules. Short term rentals need a village permit and an inspection before operating. Class A permits are capped at 15 village-wide, so availability, not eligibility, is often the binding constraint. Every permit is limited to 100 rental days a year.
Conditions the code attaches:
- Class A permits are capped at 7% of the village's residential housing stock, 15 permits. Ask about remaining capacity at the Village Hall, (845) 265-2500, before underwriting rental income.
- Class B permits are not capped in number but allow only two one-week rentals a year, a maximum of 14 days.
- The owner must reside in Nelsonville 185 days a year, occupy the unit as a primary residence, and must have lived in the home for one year before applying.
- Only residential units qualify: one-family, two-family, three-family and accessory apartments. Commercial structures, vehicles and temporary buildings are excluded.
- At least $500,000 in general liability insurance and an emergency contact within a 30-minute drive are required, and inspections are annual.
- New York State also requires every short term rental host to register the unit with the state through the county registry.
