The economic base of the City of San Luis includes professional services, retail, agri-business, and light industrial activities. This traditionally agricultural area continues to contribute significantly to the nationwide market of consumables, particularly lettuce and cauliflower in the winter months and a variety of melons during the summertime.
Residents and visitors enjoy access to professional services that run the gamut. The city's industrial base is dramatically expanding with the current renovations of the existing industrial park and construction of a brand new park located at the new International Commercial Port of Entry in East San Luis.
