Mr. Sanders is the landlord and owner of Westboro Apartments. Francine occasionally gets in trouble with him. In "Francine Goes to War," he tells Francine to stop drumming on the roof at sunrise because they had been getting complaints from a new tenant. In "Feeling Flush," he replaces the toilet lid Francine and Catherine broke. When Francine checks the water-usage meter for her apartment, he becomes suspicious that her family is using more than their fair share of water.
