History Museum Authorities Act (SB1139)

Current understanding

SB1139 would create a new History Museum Authorities Act allowing local units of government to establish history museum authorities as special public bodies (with associated governance and, per its companion bills, dedicated millage/tax treatment). The bill is tie-barred with SB1140 (brownfield exemption) and SB1141 (TIF exemption), so it cannot take effect unless both companions also pass. Status: passed one chamber as part of a three-bill package.
