Short-term rentals, known as "short-term residential rentals," in Montgomery County, Maryland, are legal but strictly regulated by the county government. The county mandates that these rentals must be the primary residence of the property owner or an authorized resident, and all hosts are required to obtain a license from the Montgomery County Department of Health and Human Services. Properties thriving in this market include urban apartments, townhouses, and single-family homes, with a notable interest in rentals in suburban neighborhoods. The demand is driven primarily by a mix of tourists and business travelers, as Montgomery County is close to Washington D.C. and has a range of corporate offices. Owners can rent their residences for up to 120 days per year when absent, and there is a maximum occupancy limit of six adults per rental. The main regulatory body overseeing the licensing and compliance for these rentals is the Montgomery County Department of Permitting Services.
