The village of Lake in the Hills remained a small, close-knit lakeside residential community for much of the 20th Century, relying on nearby towns like Algonquin and Crystal Lake for services. In 1987, the Village's first shopping center was constructed; it was built at the intersection of Algonquin Road and Oakleaf Road±. In the late 1980s and early 1990s, the Village made a series of large annexations extending west of Randall Road, all the way west to Illinois Route 47. Numerous subdivisions were constructed in this area throughout the 1990s and 2000s (decade) and retail development blossomed along Randall Road during this time period as well. By the mid 2000s (decade), development had slowed down and as the Village became landlocked by other municipalities, it worked to appropriately develop its remaining parcels.
