Signs and Advertising California 3 Minutes Read · published March 01, 2026 Flag of California

Costa Mesa, California residents and candidates must follow local sign and advertising rules that balance free expression and public safety. This guide explains where campaign signs and residential "for sale" signs may be placed, what permits or restrictions can apply, how enforcement is handled, and practical steps to comply. It summarizes the applicable municipal code and the City’s enforcement contacts so you can place signs legally, respond to complaints, and pursue appeals if necessary. Where the city text does not state a numeric penalty or time limit, this article notes that the figure is "not specified on the cited page" and points to the official sources.

General placement rules

Placement rules depend on whether signs are on private property, public right-of-way, or within commercial zoning. In Costa Mesa, signs on private property generally require the property owner’s consent; signs in the public right-of-way are typically prohibited without a permit. For official text, see the City’s municipal code and Code Enforcement pages[1][2].

Always get written permission from the property owner before placing signs on private property.

The City’s Code Enforcement and the Community Development/Planning Division enforce sign rules. Where the municipal code or enforcement pages list fines or penalties, they are cited below; where numbers are absent, the text states that they are "not specified on the cited page."
