Deck, Patio and Porch Permit

The City of Naperville requires that all decks or other secondary structures added to a residential structure have an issued building permit prior to beginning any construction. Please look at the deck application page 5 for information on patios.

Porch Safety

The City of Naperville reminds homeowners, condominium owners and apartment dwellers to visually inspect porches, balconies, elevated-free standing decks and similar structures at least twice a year for safety. Residents should check for the following signs of an aging porch:

  • Split wood, rotting wood, loose or missing nails or screws
  • Loose or missing anchors where the porch attaches to a house or building
  • Missing, damaged or loose support beams and planking
  • Wobbly handrails or guardrails

If your porch moves when one person walks or jumps on it or if you have any doubts about its safety, it is important that you have your structure inspected by a professional. When building or repairing a porch, residents must also get a building permit from the city’s Transportation, Engineering and Development Business Group.  A city inspector will then inspect your structure to make sure that it meets building safety codes.
