# US housing supply and regulatory developments > Live situation record from CLSTR: https://clstr.news/situations/us-housing-supply-and-regulatory-developments > Updated: 2026-09-15T16:09:32.000Z. Sources: 4. Developments: 2. Efforts to address housing supply shortages have expanded from state-level initiatives to national industry campaigns. In Illinois, the Illinois Realtors launched the Illinois Housing Supply Accelerator Program to work with local governments to remove regulatory and zoning barriers. This program follows stalled legislative attempts by Governor JB Pritzker to implement statewide zoning reforms. On a national scale, a coalition including Realtor.com, Zillow, and the National Association of Home Builders has expanded the ‘Let America Build’ initiative. This campaign focuses on public education and local action regarding land use and permitting to address a reported 4.03 million-home supply gap. Concurrently, consumer advocacy groups are pushing for increased regulatory scrutiny of the real estate sector. These organizations are urging state attorneys general to investigate listing platforms and referral-fee systems, arguing that certain market practices contribute to high costs for buyers and renters. ## Timeline ### 2026-09-15: US housing industry and consumer advocates launch opposing initiatives The US housing industry is launching a national campaign to increase home supply through zoning reform, while consumer advocates urge state attorneys general to investigate real estate platform practices. 2 sources. https://clstr.news/cluster/us-housing-industry-and-consumer-advocates-launch-opposing-initiatives ### 2026-08-20: Illinois Realtors launches program to tackle housing supply crisis Illinois Realtors launched a new program to help local governments remove zoning and regulatory barriers to combat a statewide housing shortage of 142,000 units. 3 sources. https://clstr.news/cluster/illinois-realtors-launches-program-to-tackle-housing-supply-crisis --- Cite as: US housing supply and regulatory developments.
