Kirkwood, MO Home Business: Signage Rules (2026)

Home-based businesses in Kirkwood get essentially no dedicated signage. Section 25-45(k)(12) of the Zoning and Subdivision Code states there shall be no permanent signs other than a wall sign for individual residential dwellings as set forth in Chapter 5, Article II, of the Kirkwood Code of Ordinances, meaning a home business cannot erect a freestanding, ground, or additional sign advertising its presence; it is limited to whatever single residential wall sign the general Sign Code already allows every dwelling. That cross-reference matters because Chapter 5, Article II is where the actual size and placement standards for that residential wall sign live, and that article's own enforcement provision makes violating any Sign Code requirement, including exceeding the residential wall-sign allowance, a misdemeanor punishable under § 1-8, with each day of a continuing violation treated as a separate offense.

The restriction is part of the broader no-impact package in § 25-45(k): the home business must not be visible from the street under (k)(4), and a prominent sign would defeat that requirement on its own even before reaching the sign-specific limit in (k)(12). A business that installs a lawn sign, a lighted sign, or any sign beyond the single residential wall sign is out of compliance with both provisions at once.
