The Community Development Department is responsible for implementing the Village's Comprehensive Plan, zoning regulations, building codes, subdivision regulations, and other Village codes as they relate to the built environment of the community. The department's two primary functions include: Planning and Zoning and Code Enforcement.

Planning and Zoning

Planning and Zoning is primarily concerned with the development, maintenance, and implementation of the Village's Comprehensive Plan, zoning ordinance, and subdivision regulations through the zoning petition process. This division works closely with the Board of Trustees, Plan Commission, Zoning Board of Appeals, and Planned Development Commission in the review and public hearing process for requests for map and text amendments, appeals, variations, special uses, planned developments within the Planned Development Overlay District, and plats of subdivision.

Code Enforcement

Code Enforcement includes enforcement of the building codes for all new construction and alteration of buildings, as well as field enforcement of zoning regulations. The division accomplishes these through the building permit process. Our employees review plans, issue permits, and inspect construction as it proceeds to ensure a safe built environment as defined by the building codes.

On April 18, 2013, the Village of Oak Brook and its residents were subject to a storm event where 6-7 inches of rainfall was received in less than 24 hours. As a result of this event, a number of our residents suffered varying degrees of damage to their homes and property.

Stay Safe

If your home or business received water please click on the hyperlink and read After the Flood before proceeding.

• Never enter a flooded portion of a building or exterior area.
• If you smell gas or if any of your gas or oil appliances were flooded, call the gas company from a neighbor's phone or cell phone (outside of the house) and have the system checked by a professional.
• Never handle any connected electrical cords or appliances that are submerged if electricity is still on. Electrical appliances that have been submerged should not be used until you have consulted with the appliance service company. Some appliances such as TV sets and radios can be a shock hazard even when unplugged.
• While the basement is still flooded, avoid flushing toilets or using other plumbing fixtures because the resulting discharge will make the basement more difficult to clean. If you have a private septic system, it should not be used until the flood waters subside.
• Never use gas pumps/generators or grills inside. These create deadly carbon monoxide exhaust fumes.
• Never run extension cords across streets.
• Be on the lookout for animals that may have taken refuge from the water.
