[Highland Park] repeated weekly yard sales

Dear neighbors, I am wondering if anyone else has noticed a spat of weekly repeated yard sales? There appears to be one home that has a weekly yard sale that ties up parking and traffic at the bottom of my street. I am wondering if there is an ordinance against such sales out of the home in a residential neighborhood. Does anyone know the legal status of such or to whom I can complain at the city level? thanks LeeAnn
