Summary
Unincorporated DuPage County bans auto repair as a home business outright. Zoning Ordinance Sec. 37-418.1(A)(6) says a home occupation shall not permit the conduct of manufacturing business or repair shop of any kind, so a residential garage cannot be turned into a paid repair operation no matter how small.
2.Shall not be operated in an accessory building or attached garage....6.Shall not permit the conduct of, manufacturing business or repair shop of any kind.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 14 Update 1).
Full Breakdown
6 draws a hard line against repair work: a home occupation shall not permit the conduct of manufacturing business or repair shop of any kind. That sentence forecloses paid auto repair, small-engine repair, or any comparable repair trade run from a house, whether the work happens in the driveway, garage, or a converted room. Two neighboring subsections reinforce the ban. 2 keeps every home occupation out of an accessory building or attached garage in the first place, so even a use that were otherwise allowed could not be based in the garage bay where auto repair naturally happens.
16 separately bars on-site storage of dangerous substances, which reaches the oil, solvents, and fluids an auto repair operation would keep on hand. 6 removes it from the list of permissible home occupations entirely rather than capping its scale. The Department of Economic Development and Planning administers Chapter 37 and fields questions on what counts as a prohibited repair shop versus an allowed occupation such as consulting or tutoring.
Violations & Fines
Operating a repair shop from a residence is enforced the same way as any other Chapter 37 violation. Under Section 37-1417, the zoning official serves a notice of violation giving the owner fourteen days to shut down the operation or request an administrative appeal; failure to comply exposes the owner to a fine of $100 to $500, with each week the violation continues charged as a separate offense, plus court costs and possible injunctive action.
