The city council voted 5-2 Monday to ban porch couches and other indoor furniture used outside.
No one testified against the proposal during the council's public hearing last week.
Supporters of the ban say it's a way to help revitalize older neighborhoods. It also likely targets college students who move in and out of rental homes. Lincoln is home to the campus of the University of Nebraska at Lincoln.
An aide to the mayor says he doesn't intend to veto the ordinance, which goes into effect Oct. 7.
At least 10 other cities have similar bans, including Ames, Iowa, Boulder, Colo., and East Lansing, Mich.
