The Department of Planning and Development is organized into two divisions, Development and Housing and Building and Zoning. While each division has specific duties, the personnel of each frequently interact to provide the most efficient method of providing customer service and implementing departmental projects. Broad areas of responsibility include:

Administration – provide overall administration of the department and reports departmental activities directly to the Mayor and Alton City Council.

Code Enforcement – maintain the public safety and welfare of the City’s physical structures and property by enforcing building construction codes, life-safety codes, property maintenance codes, accessibility codes, zoning codes, and conducting universal residential occupancy inspections.

Planning – ensures land use and general planning services in accordance with the City’s Comprehensive Plan, Zoning Ordinance, and Subdivision Ordinance. In conjunction with the responsibilities of Building and Zoning, the Department provides staff support to the City Plan Commission, Zoning Board of Appeals, Building Board of Appeals, Appearance Review Commission, and the Historic Preservation Commission.

GIS Mapping – The City of Alton actively uses a Geographic Information System (GIS) to support a range of municipal planning and administrative functions. GIS integrates hardware, software, and data for spatial analysis of geographically referenced information. The Department employs this technology to support departmental goals and objectives including, but not limited to land use planning, zoning administration, site selection, code enforcement, and property acquisition.
