Madison treats carports as accessory structures under MGO 28 zoning. Permits are required and setbacks and coverage limits match detached garage rules. Cloth or canopy carports are generally prohibited as permanent structures.
Madison MGO 28 regulates carports like other accessory structures. Permanent carports (post and roof) require a zoning permit and building permit if over 200 square feet or 10 feet tall. Standard setbacks are 3 feet from side and rear lot lines and behind the front facade in most residential districts; corner lots have additional street-side setbacks. Carports count toward the 10 percent rear yard accessory coverage maximum. Portable fabric or metal canopy carports sold at big-box stores are considered temporary and may not be used as a permanent parking structure - Building Inspection regularly cites these under MGO 28 and MGO 27.05 nuisance rules. Carports in historic districts require Landmarks Commission review. Attached carports must match the principal dwelling's setback and often need architectural compatibility review.
Unpermitted or fabric carports cited under MGO 28 with forfeitures 150 to 500 dollars plus removal orders.
