Primary-Residence-Only Rule
Nashua does not impose any primary-residence-only requirement on short-term rentals because the city has no STR ordinance. Investor-owned, non-owner-occupied, whole-unit STR operations are not prohibited as a class - they are permitted to the extent the underlying Chapter 190 Land Use Code Use Matrix permits the dwelling unit's use as transient lodging in the applicable zoning district. New Hampshire state law similarly imposes no primary-residence requirement. This contrasts sharply with cities like Bellingham, WA (270 days primary residence required for residential-zone STRs), San Francisco (host must reside 275+ days), and New York City (de facto primary-residence-only since 2023). The Chapter 190 Bed-and-breakfast section does require owner occupancy, but a B&B is a distinct classification.
