About Our Department

Community Development is comprised of three divisions: Building and Code Enforcement, Development Review, and Planning and Zoning. Learn more about our divisions and their functions below!

Building and Code Enforcement Division

St. Charles County building officers seek to identify and prevent all hazards related to the design, erection, repair, removal, demolition, or use and occupancy of buildings, structures, and premises in unincorporated areas.

This is accomplished through review of building construction plans, construction inspections, and enforcement of county building codes and regulations which set safety standards for all aspects of building construction including structural, fire, plumbing, electrical, and mechanical systems.

St. Charles County is currently using:

  • 2015 International Residential Code
  • 2015 International Building Code
  • 2015 International Plumbing Code
  • 2015 International Mechanical Code
  • 2015 International Fire Code
  • 2015 National Electric Code

These codes have been modified slightly by County Ordinance and can be found in the county's building and construction codes.

This division also handles complaints about the general condition of residential and commercial property and buildings. Tall grass and weeds, rubbish, unlicensed vehicles, commercial vehicles parked in residential neighborhoods, and peeling paint are just a few of the violations handled.

The county adopted the 2009 International Property Maintenance Code (IPMC) with several changes as the minimum standard for which county properties need to be maintained. Copyright laws restrict the county from posting the entire 2009 International Property Maintenance Code (IPMC) on the website but copies are available at any of the county libraries. You can also purchase a copy of the IPMC directly from the International Code Council online.

To view the county's Property Maintenance Code, see the St. Charles County Charter and Revised Ordinances.


Development Review Division

Development Review provides engineering review for all new development plans in unincorporated areas of St. Charles County to ensure that site improvements, including grading, erosion control, storm water facilities, and street design comply with the Unified Development Ordinance (UDO), design standards, and prudent engineering design practices. The review process is designed to minimize the impact of new development on properties outside of the development area and to ensure that all publicly dedicated facilities meet the county’s standards for public maintenance. Development Review ensures that the UDO, Design Criteria for the Preparation of Improvement Plans, tree preservation, streambank protection, and flood plain encroachment regulations are adhered to when reviewing a proposed development.

Development Review administers the county's storm water program and general state operating permit as a Small Municipal Separate Storm Sewer System (MS4). This permit also serves as the county's federal National Pollutant Discharge Elimination System (NPDES) Permit in compliance with the Federal Water Pollution Control Act (Clean Water Act).

The Division of Development Review administers the Neighborhood Improvement District (NID) Program. The division assists property owners with public improvements within a defined area of the community, established as a NID. Improvements to streets, sewers, sidewalks and other community enhancements can be accomplished through a cooperative effort between the county and residents within the NID area. The division coordinates improvement efforts and provides engineering and inspection support to the project. Residents in NID neighborhoods can choose to pay for the improvement in one lump sum or through special assessments financed by county bonds over a period of 10 or 20 years.

The Division of Development Review also oversees the Sanitary Sewer Lateral Emergency Repair program by coordinating with participating sewer providers, providing information to unincorporated county residents about the program and maintaining assessment records.
