Abstract :
I analyze the consequences of a recent statewide affordable housing planning mandate in Illinois. My survey of local officials uncovered widespread resistance and grudging compliance. At the mandate deadline, 36 of 49 prosperous suburban municipalities had the required plans, but most of these plans met the minimum legal requirements and failed to acknowledge prior exclusion or propose specific remedies. I find evidence of subregional collaboration among municipal officials, indicating they are aware of their interdependence though they remain strongly attached to local autonomy. My results demonstrate how unpopular the mandate was with local officials, potentially explaining why meeting its goals may require some time.
