Revise laws related to short-term rentals

SB 336 clarifies that short-term rentals (like Airbnb stays under 30 days) are considered residential uses, not commercial, unless explicitly prohibited by local zoning. It requires municipalities to allow short-term rentals in any zone permitting residential use (e.g., single-family homes, condos) unless banned entirely across the entire area. The bill specifically protects property owners from restrictions that would prevent renting out their primary residence or adjacent properties (e.g., a guest house on the same lot or a neighboring home sharing a boundary). Existing short-term rentals meeting state licensing and tax rules when new restrictions take effect are treated as "legal nonconforming uses," allowing them to continue operating.
