Full Breakdown
120's definitions chapter. 060, no matter how a homeowner arranges inflatable snowmen, lighted reindeer, or holiday banners across the yard. The 45-day figure is cumulative per parcel, not per holiday, so a household that keeps Halloween decorations up for three weeks and Christmas decorations up for another four weeks is tracking toward the same 45-day annual ceiling. The exemption only holds if the display carries no commercial advertising message; a decoration that doubles as an advertisement for a business would fall back under the standard sign rules and area limits for whatever zone the property sits in. 050(F), including the four-square-foot area cap and the ban on illumination for anything the City deems a sign rather than a decoration.
Violations & Fines
A holiday display that runs past 45 cumulative days a year, or that carries a commercial advertising message, loses its exemption and is treated as an ordinary residential sign subject to the four-square-foot cap and no-illumination rule in Section 20.320.050(F). An over-limit display can be cited as an illegal sign under Section 20.320.110, with a written notice and at least 15 days to cure.
