DuPage County explores new R3A and R4A zoning districts for affordable housing

The DuPage County Development Committee convened on April 1, 2025, to discuss significant zoning amendments aimed at addressing the county's housing challenges. The meeting highlighted the proposal to create two new residential zoning districts, designated as R-3A and R-4A, which are intended to facilitate the development of additional housing units in unincorporated areas of DuPage County.

The primary focus of the discussion was the need for more housing options, particularly in light of recommendations from the Ad Hoc Housing Solutions Committee. The proposed amendments would allow for the construction of two attached or detached dwelling units on smaller lots than currently permitted under existing R-3 and R-4 zoning regulations. This change aims to streamline the development process and reduce the time and complexity associated with the entitlement process for developers.

Committee members expressed concerns regarding the implications of these new zoning categories, particularly how they would affect existing properties and the potential for perceived inequities between county-owned and privately-owned properties. The committee clarified that while the new zoning districts would initially apply only to county-owned properties, private property owners could also petition for their properties to be rezoned to R-3A or R-4A, provided they go through the necessary public hearing and approval processes.

The committee emphasized that the creation of these new zoning districts is a strategic move to enhance the county's housing program, which may include initiatives like land banking and housing trusts. By establishing these districts, the county aims to make it easier for developers to build affordable housing, thereby addressing the growing demand for residential units in the area.

In conclusion, the meeting underscored the county's commitment to improving housing availability while navigating the complexities of zoning regulations. The proposed amendments will be subject to further review and public hearings, allowing for community input and discussion before any final decisions are made. As the county moves forward with these initiatives, the implications for both developers and residents will be closely monitored.
