Summary
Holiday light displays and decorations count as "decorative signs" under Sioux City's zoning code and don't need a sign permit, though residential districts bar them from encroaching into the public right-of-way.
2. Decorative Signs. Signs that are clearly incidental, customary, and commonly associated with a holiday are permitted, provided:
A. In the Rural Residential (RR), Suburban Residential (SR), General Residential (GR), and Urban Residential (UR) districts, as well as each of the Neighborhood Conservation (NC) sub-districts:
I. Banners or signs that promote non-commercial special events are prohibited; and
II. Holiday decorations are permitted provided they do not encroach into public street right-of-way.
B. In all other districts:
I. Each sign or decoration may be erected up to 30 days before a promoted event and must be removed within 10 days after the completion of the promoted event; and
II. If the erection of any decorative sign or holiday decoration promoting a non-commercial special event will encroach into public street right-of-way, a temporary permit may be issued pursuant to Section 17.28.020, Encroachments, under Title 17, Streets and Sidewalks, of the Municipal Code. An encroachment permit must be obtained before any such decorative sign or holiday decoration may be erected.
3. Directional / Information Signs. One sign, illuminated or non-illuminated, with a cumulative sign area per Subsection 25.05.180.3.
Full Breakdown
Sioux City's zoning code treats holiday lights and decorations as 'Decorative Signs,' which are exempt from the sign permit requirement (Sioux City Municipal Code § 25.05.140, Item 3.a.2). In the Rural Residential, Suburban Residential, General Residential, and Urban Residential districts and the Neighborhood Conservation sub-districts, holiday decorations are allowed outright as long as they don't encroach into the public street right-of-way. In every other district, holiday or event decorations tied to a promoted event can go up no more than 30 days before it and must come down within 10 days after; encroaching into the right-of-way there needs a Title 17 encroachment permit. Flashing holiday lights are also exempted from the code's general ban on flashing signs (§ 25.05.170.2.5.b.3).
Violations & Fines
Decorations that encroach into the right-of-way without an encroachment permit, or that stay up past the 10-day removal window outside residential districts, lose the exemption and become subject to removal as a prohibited sign under § 25.05.170.3.
