Political Signs
California Business & Professions Code §5405.3 (part of the Outdoor Advertising Act) governs temporary political signs and preempts conflicting local rules along regulated roadways. Statewide, a political sign that (a) encourages a vote in a scheduled election, (b) is posted no sooner than 90 days before the election, (c) is removed within 10 days after the election, and (d) does not exceed 32 square feet, is allowed on private property with the property owner's consent. Carson's Municipal Code (Article IX, Chapter 1 — Zoning, sign regulations) regulates the physical placement of signs (setbacks, visibility triangles, public right-of-way prohibitions) but cannot impose content-based restrictions on political speech beyond what the First Amendment allows under Reed v. Town of Gilbert, 576 U.S. 155 (2015). Signs in the public right-of-way, on utility poles, or on traffic-control devices are prohibited.

Few RestrictionsGarage Sale Signs
Carson regulates garage sale (yard sale) signs through its zoning sign provisions in Article IX, Chapter 1 of the Municipal Code (ecode360.com/47274121). The consistent rule across LA County contract cities is that garage sale signs may be displayed on the property holding the sale during sale hours but may NOT be posted in the public right-of-way — that includes parkway strips, utility poles, traffic signs, street light standards, street trees, and median islands. Off-site signs are prohibited and subject to immediate removal by Public Works. Signs on private property other than the sale site require the property owner's consent and may not exceed the zoning code's temporary-sign size limits.
Garage Sale Signs: No Signs in Public Right-of-Way; On-Site Only
Some RestrictionsHoliday Displays
Carson has no ordinance specifically regulating residential holiday lights or seasonal yard displays. Holiday decorations on private property — Christmas lights, inflatable yard figures, Halloween decor, Diwali lights, menorahs, religious displays — are protected expression under the First Amendment and are not separately permitted or restricted. However, three Carson/state rules can apply: (1) general nuisance provisions in Carson Municipal Code Article 4 (Public Peace) if a display creates ongoing traffic hazards or crowds; (2) the LA County Code Title 12 Chapter 12.08 noise ordinance (adopted by reference into Carson via Article 4, Chapter 5) if amplified holiday music exceeds 65 dBA daytime / 50 dBA night at a neighboring property line; and (3) Title 24 California Electrical Code if temporary outdoor wiring is unsafe. No customary 'take-down deadline' exists in Carson code.
Holiday Lights & Displays: No Specific Local Ban; General Nuisance & Light Pollution Apply
