Applications & Forms

The City of Naperville does not publish a homeowner pesticide-notification form or permit on the primary municipal code page; a dedicated municipal application form for homeowner pesticide notification is not specified on the cited page.

  • Order or notice: if a violation is found, the city may issue an order to correct or cease the activity.
  • Penalty or civil action: if the city code provides fines or civil remedies applicable to the conduct, those may be pursued by the enforcing department.
For pesticide concerns that affect health or the environment, report promptly to city code enforcement and keep records of dates and applicator information.
