Summary

Longmont's sign code flatly prohibits inflatable signs -- balloons, inflatable figures, and similar fluttering or revolving devices -- with no seasonal or temporary-permit exception, unlike pennants and windsocks.

The following signs are prohibited unless otherwise stated in this chapter:

A.Distracting, interfering or confusing signs.1.Signs that cause visual obstruction or interfere with motor vehicle traffic or a traffic control device, including any sign that obstructs clear vision in any direction from any street intersection or driveway.2.Signs employing a lighting or control mechanism that causes radio, radar, or television interference.3.Signs that obstruct any fire escape, window, door, or opening used or required as a means of egress or ingress, or for emergency purposes, or that interfere with any openings required for light or ventilation.4.Signs in rights-of-way or on other public property unless specifically permitted or provided for in this chapter.B.Animated or moving signs.1.Animated or moving signs except for scoreboards for athletic events, time and temperature devices, electronic message signs used by the city or other public agency to address a health or safety matter or public service announcement or permitted electronic message signs.2.Inflatable signs such as balloons and inflatable figures, or other similar moving, fluttering, or revolving devices.3.Pennants and windsocks, unless approved with a temporary sign permit.C.Feather flags. Feather flags and similar devices, unless approved with a temporary sign permit (figure 6.1). Figure 6.1: Feather Flag

Full Breakdown

Longmont's prohibited-signs list bans inflatable signs -- balloons, inflatable figures, and similar moving or revolving devices -- outright. That's a harder line than the code takes with pennants and windsocks, which the very next clause allows if the applicant gets a temporary sign permit; inflatable figures get no such carve-out. Because the code defines a 'sign' broadly to include any decoration designed to attract attention, a large seasonal inflatable set up to draw notice to a business or property functions as a prohibited sign under this rule.

Violations & Fines

Displaying a prohibited inflatable sign is a sign code violation; the city can require its removal and pursue enforcement under the development code's general violation and remedy provisions.
