Caldwell, ID Sign Regulations: Political Signs (2026)

Caldwell City Code section 01-07-02 defines electioneering to include the posting, use or distribution of political signs, cards, placards or literature, and flags, but exempts shirts, caps, hats, facial masks and buttons carrying a political message. Under paragraph (1)(A), citing Idaho Code section 18-2318, the city bars electioneering within a polling place or any building where an election is held, or within one hundred feet of it, and Caldwell interprets that as no electioneering closer than 100 feet to a polling site's entry door, with authority to extend the buffer further given perimeter streets and parking lots.

Paragraph (2) bars any political signage, banner or expression on, in or over city right of way, including attachments to fencing or landscaping in that right of way. Paragraph (3) bars the same on any city-owned premises, naming City Hall, the Library and the Police Department specifically. Paragraph (4) sets no numeric cap on private-property signage, though the city encourages a respectful, reasonable limit per candidate or proposition. Enforcement runs through the Caldwell Police Department under paragraph (8), with the City Clerk's Office empowered under paragraph (10), in consultation with the City Attorney's Office, to resolve electioneering disputes not otherwise addressed. The rule was adopted by Ordinance 3467 on November 15, 2022 and sits in the Elections article of Title 1.
