Summary
Antioch requires a written permit from the City Engineer before anyone builds, plants, digs, or places anything in a public right-of-way, including the sidewalk and planting strip. Unpermitted encroachment is a misdemeanor and a public nuisance, and some encroachments cannot be permitted at all.
No person shall encroach, or cause to be made any encroachment of any nature whatever, within, upon, over, or under the limits of any right-of-way or watercourse; or make or cause to be made any alteration of any nature within, upon, over, or under the limits of any right-of-way or watercourse... or construct, put upon, maintain, or leave thereon, or cause to be constructed, put on, maintained, or left thereon, any obstruction or impediment of any nature whatever... without having first obtained a permit as required by the provisions of this chapter.
Full Breakdown

Violations & Fines
Encroaching without a permit or violating permit conditions is a misdemeanor under the code's general penalty, AMC § 1-2.01, punishable per Cal. Penal Code § 19, though the City Attorney has sole discretion to reduce a violation to an infraction (punished per Penal Code § 19.6). Each day a violation continues is a separate offense. The city also treats unpermitted or nonconforming encroachments as a public nuisance and can prosecute, seek civil remedies, or obtain a Superior Court injunction against the property owner, occupant, or responsible party. The City Engineer can additionally cancel a permit for lack of diligence and restore the right-of-way at the permittee's cost, and can require bonds under Article 4 to cover the city's restoration expenses.
