St. Louis Encroachment Permit Steps - Street Work

Transportation Missouri 3 Minutes Read · published February 09, 2026 Flag of Missouri

In St. Louis, Missouri, any work that occupies or alters the public right-of-way — including sidewalks, curb lanes, and roadway lanes — typically requires an encroachment or right-of-way permit. This guide explains the common steps to apply, who enforces the rules, typical compliance checks, and how to appeal or report violations in St. Louis.

Overview

Encroachment permits regulate temporary or permanent use of public streets for construction, utility work, scaffolding, storage of materials, or other obstructions. Projects range from short-term maintenance to multiweek construction zones and usually need traffic control plans and proof of insurance. Applicants should plan for coordination with utilities and neighborhood impacts and allow time for plan review and possible revisions.

Apply early — permit review and traffic plan coordination take time.

Enforcement tools commonly include stop-work orders, removal orders for obstructions, suspension or revocation of permit privileges, and civil fines or citations.
