Summary
Political signs on private property in unincorporated San Joaquin County are protected as core political speech under the First Amendment and Reed v. Town of Gilbert (2015). Development Title §9-1040 allows signs up to 32 square feet in residential zones during campaign periods, prohibits placement in the public right-of-way, and requires removal within 10 days after the election. Stockton, Lodi, and Manteca have parallel rules in their respective sign codes.
The governing documents may not prohibit posting or displaying of noncommercial signs, posters, flags, or banners on or in a member’s separate interest, except as required for the protection of public health or safety or if the posting or display would violate a local, state, or federal law. (b) For purposes of this section, a noncommercial sign, poster, flag, or banner may be made of paper, cardboard, cloth, plastic, or fabric, and may be posted or displayed from the yard, window, door, balcony, or outside wall of the separate interest, but may not be made of lights, roofing, siding, paving materials, flora, or balloons, or any other similar building, landscaping, or decorative component, or include the painting of architectural surfaces.
Full Breakdown
San Joaquin County Development Title §9-1040 permits temporary political signs on private property without a permit, limited to approximately 16 square feet per sign in residential zones and 32 square feet in commercial/industrial zones, with no numerical cap per parcel. Signs may be posted for a reasonable campaign window and must be removed within 10 days after the election to which they relate. Placement in the public right-of-way, on utility poles, on traffic control devices, or on county-maintained medians is prohibited and signs are subject to immediate removal by Public Works without prior notice.
Content-based restrictions, such as different size or timing rules for political versus commercial messages, are unconstitutional under Reed v. S. 155 (2015), so the county enforces only time, place, and manner rules. 58 follow the same pattern with similar post-election removal deadlines (7 to 14 days). Caltrans enforces separate rules under Streets & Highways Code §5200 for signs within state-highway right-of-way along I-5, I-205, SR-99, SR-120, and SR-4.
Violations & Fines
Political sign in public right-of-way: immediate removal by Public Works with no fine typically assessed on first violation. Oversized sign: courtesy notice to reduce. Failure to remove within 10 days after election: $25 to $100 per sign per day, enforced by Community Development. Signs in Caltrans right-of-way: confiscation plus Streets & Highways Code §5200 penalties up to $100 per sign.
