Short-term rentals (STRs), referred to locally as "alojamientos a corto plazo," are legal in Arroyo Municipality, Puerto Rico, but they are subject to specific regulations set forth by the Puerto Rico Tourism Company and the municipal government. Property owners must register as innkeepers, obtain necessary permits, and comply with the Puerto Rico Hostelry Regulation which stipulates that a structure for STR use cannot exceed six rental units. STRs in Arroyo predominantly feature rural cabins and beachfront properties, catering mainly to tourists drawn to the area's natural attractions and coastal views. The market is influenced by seasonal tourism, with a notable uptick during holidays and summer months, rather than being heavily reliant on business travelers. Oversight of these regulations falls under the jurisdiction of the Puerto Rico Tourism Company, which also administers pertinent taxation.
