Overview: Are Short-Term Rentals Allowed in Waltham?

Short-term rentals are explicitly prohibited in Waltham for Accessory Dwelling Units (ADUs) according to the city's zoning ordinance amendments (see Section 3.23(e) of the proposed ADU regulations). However, based on the provided content, there are no specific city-wide regulations prohibiting short-term rentals in primary residential units or other property types.

This means that while ADUs cannot be used as short-term rentals, other property types in Waltham may potentially operate as short-term rentals, subject to Massachusetts state regulations and any applicable local ordinances that may exist but are not captured in the provided content.
