HB 5312 modifies existing rules governing the sale, lease, or use of unused or underused school district facilities. It mandates that school districts must first offer these properties to public school districts, open-enrollment charter schools, or private schools before selling them to the general public. A 90-day window is established for education institutions to submit offers, and if no qualifying bids are received, the property may be offered for public sale. However, if a general public offer is accepted, education institutions have 14 days to match the offer before finalizing the sale​.
