Summary
Madison restricts home-business signage to almost nothing: Sec. 28.151(l), MGO says the only exterior sign a home occupation may display is a non-illuminated nameplate no larger than two square feet. Everything else, window displays, illuminated signs, banners, larger placards, is off the table for a home business operating under the home occupation standards.
(l)The only exterior indication of the home occupation shall be a non-illuminated nameplate a maximum of two (2) square feet in area.(m)A home occupation of an individual with a disability, who is incapable of employment outside the home by reason of significant physical or mental disability, as verified by a signed physician statement verifying the disability, is exempt from the requirements of subparagraphs (g) through (k).
Full Breakdown
The Home Occupation standard in Sec. " That phrasing does more than set a size cap, by naming the nameplate as the ONLY exterior indication permitted, it rules out every other form of exterior advertising for a home occupation, including illuminated signs, window displays, banners, sandwich boards or larger placards, regardless of what a business might display if it operated from a commercial storefront instead. The two-square-foot nameplate is also tied to the broader home occupation requirement in subsection (b) that the business stay "clearly incidental and secondary" to the dwelling's residential use, a prominent or illuminated sign undercuts that showing and puts the whole home occupation's by-right status at risk, not just the sign itself.
The disability exemption in subsection (m) does not reach the sign rule: it only exempts qualifying operators from subsections (g) through (k), so even an exempt home occupation must still comply with the (l) nameplate limit. Enforcement runs through the Zoning Administrator, and any exterior sign that exceeds the two-square-foot cap or uses illumination is a violation of Chapter 28, subject to the general zoning penalty in Sec. 207(1), MGO.
Violations & Fines
Installing anything beyond a single non-illuminated, two-square-foot nameplate, an illuminated sign, a larger sign, a banner or a window display, violates Sec. 28.151(l), MGO. Sec. 28.207(1), MGO makes any Chapter 28 violation punishable by a forfeiture of not less than $1 and not more than $1,000 upon conviction, and the oversized signage can also jeopardize the home occupation's underlying by-right status.
