The second fire was in 1914 and consumed the north side of the downtown business section. The third fire took place about ten years later, in 1925, and again, the northern side of the downtown business district was destroyed. As a result of the 1925 fire, the Mount Airy Volunteer Fire Company was organized in 1926. During the late 1920s and early 1930s the town continued to flourish despite the onset of the Great Depression. The 1930 U.S. Census tallied the town population at 845 persons, an increase of 91 people since 1920. The railroad company largely contributed to the growth of not only the population, but the town's economy as well. As a result, expanded town services included necessary public utilities such as electric service when Potomac Edison was established in Mount Airy. The thriving economy supported the initiation of several large businesses in the 1930s, such as a poultry operation, two automobile garages, an ice factory, and the creation of the Mount Airy Canning Company, which provided about 250 jobs. In 1932, the first motion picture theater opened in Mount Airy, establishing a core business district. During that time, the town also saw the purchase of land for a town park, the opening of a grocery store and a lumberyard, and the dedication of Pine Grove Chapel for use as a nonsectarian chapel. The Mount Airy Historic District that includes the railroad station was added to the National Register of Historic Places in 1984. Currently, Mt. Airy is no longer economically dependent on the railroad, as citizens work a variety of different jobs. Many of its citizens work in Washington, DC, or Baltimore; the city is a part of both of those cities' metropolitan areas. Airy is a neighborhood community for these job centers. Airy is similar to back in the day with the National Road but now with Interstate 70 bordering the southern end of the city with an interchange with MD-27. In the last few decades Mount Airy has seen significant growth, as laid out in the Mount Airy Master Plan from the 1994 to 2003 update. In 2007 President George W. Bush made a speech in Mount Airy. Airy hosts townwide events each year including the Main Street Chili Cookoff, Celebrate Mount Airy in August, Mount Airy Oktoberfest in September, and A Main Street Christmas in December.

Mount Airy is located on the border between Frederick and Carroll counties, in the far eastern part of Frederick County and the southwest corner of Carroll County.
