The City of Naperville requires that all decks, patios and open porches added to a residential structure, or the installation of other secondary structures on the property, have an issued building permit prior to beginning any construction.
Decks and Patios
The construction of any elevated deck, gazebo, pergola or porch requires a building permit. Maintenance of an existing deck may be performed without a permit as long as no handrails or structural members are being replaced. Installation or expansion of an existing patio requires a building permit, unless the total area of the resulting patio is 500 square feet or less. Any patio that includes permanent fire pits, fireplaces, grills, stairs or landings, electrical, plumbing or gas fixtures will require a permit. All patios, regardless of the need for a permit, must still follow all setback and easement restrictions.
Sheds and Coops
The construction of a storage shed or playhouse with a floor area exceeding 150 square feet requires a building permit. The installation or expansion of any pen, coop, building or other enclosure used for the purposes of housing fowl or livestock, regardless of size, also requires a building permit.
Deck and 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.
