Home-business signage is regulated primarily by the local city or township within Wayne County. Most jurisdictions limit home-occupation signs to one non-illuminated wall sign under two square feet.
Wayne County does not maintain a countywide home-occupation sign standard because land-use regulation rests with the 43 cities and charter townships within its boundaries. Detroit, Livonia, Dearborn, Westland, Taylor, Canton Township, Plymouth Township, and Redford each publish sign standards as part of their zoning ordinance chapters on home occupations. Typical limits: one flat wall-mounted sign, two square feet or less, non-illuminated, displaying only the occupant name and profession. Freestanding pole signs, lighted signs, A-frame sidewalk signs, and window signs advertising prices are generally prohibited in residential zones. The First Amendment protects certain non-commercial and political messages, but commercial home-business signage remains subject to reasonable time, place, and manner regulation under Reed v. Town of Gilbert. Always verify standards with your specific municipality before installing any sign, and confirm whether a sign permit is required.
