Maple Valley is fortunate to have two primary commercial nodes, one each in the north (Hwy 18) and south portions of the City (Hwy 516), both straddling Highway 169. There are also two smaller, neighborhood scale, commercial areas on Highway 516, along with a small light-industrial area on Highway 169 in the extreme south end of the City.

The primary commercial nodes are anchored by recently remodeled grocery stores which are each surrounded by a wide variety of retail, restaurant, professional service and office businesses. Although several regional and national chains have locations in the City, most Maple Valley enterprises are locally-owned small businesses. The neighborhood scale commercial areas are home to several professional offices and other businesses. Two regional health care providers have locations in the City, one in the neighborhood scale area on Hwy 516 and one in the southern primary node.
