Garrett married Eliza Clark in 1825 and moved to Chicago from New York in 1834. He had a small auction house near the Chicago River and by the following year had formed a partnership with the Brown Brothers, which allowed him to become a leading land speculator and auctioneer. By October 1836, he had sales of more than $1.8 million.
Elected mayor in 1843, he won re-election in 1844 only to have the election invalidated based on charges of "illegal proceedings and fraud." Garrett ran in a second election that year, losing to Alson Sherman. During his terms in office, Garrett pushed to have the first brick school in Chicago, Dearborn School, turned into either a warehouse or an insane asylum, believing that the building was too large for use as a school.
