The Jackson House, a place where many blacks people stayed when they were barred from the whites-only hotels in the early 1900s , got one step closer Thursday to being designated a historic site. The Tampa City Council voted unanimously to officially open the process. The house's builder, Moses Jackson, helped lay the original trolley tracks in Tampa. He constructed the home, at 851 E Zack St., with handsaws. The plan must now be reviewed by the Planning Commission, then returns to the City Council for a vote.
