Vacation rentals at times allow for longer stays as opposed to hotels, and longer stays increase visitor spending which provides more employment opportunities in local communities. Increases of tourist spending in a vacation rental area helps fuel the economy through the multiplier effect by increasing wages. Some businesses like Airbnb are starting to use their popularity to contribute to more sustainable travel. Airbnb’s program, called Social Impact Experience, involves rental hosts advertising and holding activities for their guests that are provided by a nonprofit organization of the hosts choosing. This feature supports sustainable travel as it allows visitors to get involved in local organizations that help better the community in which they are travelling to. Vacation rentals can also negatively affect local communities in a number of ways. While not the major cause of limited affordable housing, vacation rentals negatively affect the long-term housing market in local communities, especially tourism communities. As more short-term rentals increase, the availability of long-term units decreases. However, HBR researchers point out that “owner-occupiers” that rent out rooms or the entire house while they are absent does not affect the long-term rental market. Another implication of short-term vacation rentals is that local communities can be disrupted by guests in unfamiliar neighborhoods. Visitors may be uninformed of the culture, attitudes, and unspoken guidelines of a neighborhood in which they are staying in. Loud parties after quiet hours, lack of consideration for residential parking, and cultural interpersonal differences are a few of the primary concerns for residents with nearby vacation rentals. Restrictions In many counties, towns, and cities, local authorities attempt to regulate or ban vacation rentals after complaints from local residents or competing lodging businesses. In the U.S. New York City, Chicago and other cities have introduced restrictions on short-term rentals, though regulation is not always strictly enforced. The City of Portland, for example, does not allow rentals of less than 30 days in residential zones but according to local vacation property managers such as Vacasa, the average guest stays 3-10 nights. San Diego, California has also created similar restrictions. Starting in 2022, the city put a cap on the number of properties that could be used as short-term vacation rentals at 1%. This restriction was approved
