Rialto regulates temporary signs (including political/campaign signs) under Title 18 Zoning, Chapter 18.78 Sign Regulations. Content-neutral standards apply to size, height, location, and removal. State law (Cal. Gov. Code §65850 and First Amendment case law, e.g., Reed v. Town of Gilbert) prohibits content-based discrimination, so political signs are generally treated as temporary signs subject to the same neutral time/place/manner rules.
Under Rialto Municipal Code Title 18, Chapter 18.78 (Sign Regulations), temporary signs in residential zones are limited in size and number, must be placed on private property with owner consent, and may not be placed in the public right-of-way or attached to utility poles, street trees, or traffic-control devices. The City applies content-neutral standards consistent with Reed v. Town of Gilbert (2015). California Elections Code §20008 prohibits cities from restricting political-sign size below 32 sq ft, restricting display to less than 90 days before an election, or requiring removal sooner than 10 days after the election on private property along non-state highways. Signs in the Caltrans right-of-way are governed by Cal. Outdoor Advertising Act (B&P §5200 et seq.).
Signs in the public right-of-way, on utility poles, or on traffic-control structures may be removed by Rialto Public Works/Code Enforcement without notice. Repeat or commercial violations may be cited under Title 1 general penalty (Rialto MC §1.16) as an infraction or misdemeanor, with fines escalating per occurrence.
