Short-term rentals (STRs), often referred to locally as "Airbnbs," in Montgomery County, Pennsylvania, are legal but strictly regulated by local ordinances. All operators must obtain a license from the county's Department of Health and Human Services, which involves a $150 fee and compliance with zoning regulations, including a requirement that the rentals be the owner's primary residence. Rentals are capped at a maximum of 120 days per year to ensure that they are primarily used for owner-occupied housing. The county has seen an increase in urban apartments and rural cabins servicing both business travelers and tourists, particularly due to proximity to attractions and urban centers. The market dynamics are influenced by a mixture of local tourism and business travel, with enforcement of regulations being somewhat contentious as many community members voice concerns about unlicensed rentals impacting housing affordability. The Department of Health and Human Services oversees these operations, ensuring compliance with the relevant health, safety, and zoning requirements.
