Authorizes expansion of regional jail districts upon voter approval

HB 492 establishes rules for counties to form or expand regional jail districts covering multiple counties. It requires voter approval in any county joining an existing district that levies a sales tax (up to 1% on retail sales) for jail services. The bill outlines how districts operate - including commission structure (sheriffs and county commissioners), cost-sharing formulas, and authority to build or lease facilities - and mandates that new counties must get local voter approval for the tax before joining. This directly affects participating counties and their residents through potential sales tax changes for regional jail funding.
