The available property inventory is provided as a complimentary service to Mascoutah property owners and the business community. The databases have been integrated with LOIS (a national economic development building, site and community database system). For each available site you find property images, utility information, ESRI demographics, and more. Mascoutah property owners may update or add their building or land information at any time.
