Overview

The City of Naperville regulates encroachments in public rights-of-way through its Engineering/Public Works permitting process. Contractors must obtain an encroachment or right-of-way permit for work that obstructs sidewalks, streets, parkways, or other public property; unstated exceptions or variances must be approved in writing by the issuing department. Permits typically require approved traffic control plans, insurance, and bond or restoration guarantees.

Penalties & Enforcement

Specific monetary fines and fee schedules for unauthorized encroachments are not specified on the cited permit page.[1] The city enforcer for encroachment matters is the Public Works/Engineering division, which inspects work, issues stop-work orders, and may order removal or restoration at the permittee's expense. Where the municipal code specifies penalties for obstruction or unauthorized work, the code text controls; if a fine amount is absent on the permit page, it may be listed in the Naperville Municipal Code or assessed via administrative order.

Unauthorized work in the right-of-way can trigger a stop-work order and mandatory restoration.
