Springfield, IL Home Business: Signage Rules (2026)

The City of Springfield restricts home-business signage in two places in the Zoning Ordinance. 045(c)(3) provides that a home occupation must have no exterior storage of materials and no exterior indication of the home occupation except for a sign not exceeding two square feet in size, non-illuminated, and attached to the principal building. 311(a) provides that for residential buildings other than multiple dwellings, one non-illuminated nameplate with an area not exceeding one square foot, indicating only the name or address of the occupant or a permitted occupation, is allowed for each dwelling unit.

315 adds that any such residential sign may not extend more than 20 feet above ground, must sit at least ten feet from the front property line, and is limited to one sign per use, building, or dwelling unit. Free-standing commercial signs, illuminated signs, and signage advertising prices or products are not permitted for a home occupation in a residential district. The practical limit for a home-occupation sign is therefore a small, non-illuminated nameplate attached to the home.
