Summary
Madison's sign code treats most inflatable displays as regulated signs, but MGO § 31.046(3)(c)3 carves out an exception: inflatable noncommercial displays such as seasonal or holiday decorations on residential property aren't considered signs at all, and need no sign permit, as long as they stay temporary and don't exceed 15 feet in height.
(3)Inflatable Signs. Inflatable signs, other than the exceptions enumerated herein, shall be prohibited because they are generally more distracting and hazardous to pedestrian and traffic safety, tend to have an anchoring device that is less reliable under wind pressure, and out of scale and less compatible with surrounding structures and signs...(c)The following inflatable devices shall not be considered a sign:1.Registered hot air balloons in use and momentarily moored but not being used primarily as a sign.2.Novelty-type balloons less than two (2) feet in diameter and less than three (3) feet in any dimension tethered or moored no more than ten (10) feet above the ground.3.Inflatable noncommercial displays, such as seasonal or holiday decorations, displayed temporarily on private property of a residential use, that do not exceed fifteen (15) feet in height.
Full Breakdown
056 that carry $1,000,000 in liability insurance and follow a 35-foot height cap, a 60-foot setback from the traveled roadway and a 100-foot setback from any intersection. 046(3)(c) lists three categories of inflatable devices that aren't considered "signs" at all: registered hot air balloons momentarily moored but not primarily used as a sign; novelty-type balloons under two feet in diameter and less than three feet in any dimension, tethered no more than ten feet above the ground; and, most relevant here, inflatable noncommercial displays such as seasonal or holiday decorations displayed temporarily on residential private property, capped at 15 feet in height.
Because that third category falls outside the sign definition entirely, a homeowner's inflatable snowman, pumpkin or Santa doesn't need a sign permit, doesn't count toward the property's sign allowance, and isn't subject to the general inflatable-sign prohibition, as long as it's on a residential lot, displayed temporarily rather than year-round, and doesn't exceed 15 feet.
Violations & Fines
An inflatable holiday display that exceeds 15 feet, sits on non-residential property, or is left up as a permanent fixture loses the exemption and becomes a regulated "inflatable sign" under MGO § 31.046(3), which the city prohibits outright outside the parade and permitted-event exceptions: exposing the owner to a forfeiture of $30 to $500 per day under § 31.19 and a possible removal order from the Zoning Administrator.
