Full Breakdown
Section 11-4-10(B)(3) of the Westminster Municipal Code addresses the only outside evidence a home business is permitted to show. " That means no yard signs, no illuminated signs, no moving or animated displays, and no signage beyond a single small wall or window placard. This sits inside the broader home occupation framework: the business must otherwise stay entirely inside the dwelling, be run only by residents, and avoid changing the character of the home or neighborhood through outward signs of commercial activity. Because the sign limit is a subsection of the home occupation licensing rule, a home business that installs a larger or lit sign is not just a sign violation, it also puts the underlying home occupation license itself out of compliance with Section 11-4-10.
Violations & Fines
A sign exceeding one square foot, an illuminated sign, or any sign not flat against a wall or window is a violation of Section 11-4-10(B)(3) and renders the home occupation noncompliant, exposing the operator to the nuisance-abatement process in Subsection (D) under Title VIII, Chapter 4 of the Code, including possible license revocation.
