Glen Ellyn Building Permits: When a Deck Job Needs One

What this comes down to

  • Replacing rotted deck boards with equivalent ones usually needs no Glen Ellyn permit, but altering the structure does.
  • The village's permit list names decks, porches, stoops, stairs, sheds, fences, arbors and pergolas.
  • Ordinary repair skips the permit only when materials match, structure is untouched and loads do not increase.
  • Permit applications received after January 1, 2024 are held to the 2018 International Residential Code.
  • A deck application needs three copies of the plat of survey and three sets of construction plans.
  • Contractors must meet Village Code Section 4-1-11 on license and insurance, or risk a stop work order.

Inside Glen Ellyn, deck permits come from the village itself. It publishes its own list of work that needs a building permit. The deck rules sit inside that list. Unincorporated areas follow the county permit application guide instead.

This guide reads the village's list for a deck owner. It covers what counts as ordinary repair, which code applies and what the application asks for. It also covers who may do the work. It ends with what only the village can answer.

Do I need a building permit in Glen Ellyn?

Yes, for any new deck, porch, stoop or stair. The Glen Ellyn Community Development Department keeps a village permit list that names each of them. It also names sheds, fences, arbors and pergolas.

The list covers a new structure of any size, type or use. It also covers enlarged, altered or remodeled outdoor structures. Stairs get a line of their own. A deck that grows or gets new stairs is no longer a repair.

Does a deck repair need a permit in Glen Ellyn?

Often not, when the repair is like for like. The same department says ordinary repair and maintenance typically needs no permit. Replacement materials must be equivalent to the existing ones. Structural components must stay unaltered and loads must not increase.

Three rotted boards replaced with three matching boards fit that test. A joist swapped for one of the same size and grade is a gray area, so ask first. A moved beam, a hot tub or a wider deck is a permit job.

The village also says its list is not complete. The Building and Zoning Official interprets the code. That official can confirm a specific property from a full description of the work. The state view is in the guide to Illinois deck permit rules.

What other work in Glen Ellyn needs a permit?

Several jobs that often come with a deck. A patio or other paving over 100 square feet needs one. So does replacement roofing over 300 square feet or 20 percent of the roof. Siding and cladding follow the same limits.

Gutter downspouts and waterproofing at grade are on the list. So are new or altered doors and windows. Any work in or within 30 feet of a designated flood area needs a permit as well. A neighboring town sets its own limits, as the Wheaton permit rules show.

Which building code does Glen Ellyn enforce?

The 2018 International Residential Code, for permit applications received after January 1, 2024. The village's adopted code list also names the 2018 building, fire and mechanical codes.

The same list adds the 2017 National Electrical Code. The 2024 energy code applies as amended by Illinois. The village attaches local amendments to these codes, so the model code is only the starting point. The Illinois deck building code guide covers the state layer.

What does the code require of the deck itself?

Sound materials, set on footings below the frost line. The International Code Council's 2018 residential code puts decks in section R507. The code's deck chapter spells out the rules. Wood must be No. 2 grade or better.

Wood must also be preservative treated or naturally durable lumber. Plastic composite boards must carry an ASTM D7032 label showing allowable load and span. Flashing must be corrosion resistant metal at least 0.019 inch thick. An approved nonmetallic material also works.

Composite boards also go in under the manufacturer's instructions. Footings must extend below the frost line, which keeps a post from heaving when the ground freezes.

The footing is the part an inspector wants to see open, because the post and soil hide it once work moves on.

What does a Glen Ellyn deck permit application require?

The village's permit application form for outdoor structures lists what must be submitted. The Community Development Department asks for these items, listed here in the form's order:

  • A permit application signed by the property owner.
  • A plan review fee, in an amount the permit clerk sets at submission.
  • A contractor listing sheet, completed on the application packet.
  • Three copies of the plat of survey, marked with the work and its distances from the house and lot lines.
  • Three copies of construction plans containing the construction details.

Two more plans depend on size. A tree preservation plan is required when more than 300 square feet is disturbed. It is also required when a structure grows by 20 percent or more. A drainage or stormwater plan is required when more than 300 square feet is disturbed.

Who is allowed to do the work?

A contractor who meets the village's license and insurance rules. The application says every contractor must comply with Village Code Section 4-1-11. Each must be named when the application is submitted.

The same page warns of a Stop Work Order, or suspension or revocation of the building permit. Ask any deck contractor to name the license and insurance on file before work starts.

What gets inspected, and when?

Each stage listed on the permit. The application's certification covers inspections. Each stage must be requested and approved before the next stage begins on site.

On a deck, the stages are usually the footings, the frame and the final. The permit itself lists the ones that apply. Footing holes come first, because concrete and posts hide them once poured.

Digging carries its own rule. The village's regulation list includes the Illinois underground utility damage prevention act. It is known as JULIE. Contact JULIE before any footing hole is dug, since a post hole can meet a buried line.

Which deck jobs need a permit in Glen Ellyn?

The table applies the village's list to common deck jobs. It is a reading of the published list. It is not a ruling, because the village decides each property itself.

What does the work cost around a permit?

The village sets its own fees, and the plan review fee is set by the permit clerk at submission. The work itself is priced separately. Starting prices for the common deck jobs are below.

The workStarting priceWider marketWhat moves it
Deck board replacement over a sound frameFrom $10 per sq ft$12 to $25 per sq ftBoard type and access

New pressure treated deckFrom $24 per sq ft$26 to $50 per sq ftSize, height and footings
Minimum service call$99 minimum$120 to $200 typicalTime on site

What cannot be determined without the village?

The permit fee. The plan review fee is set at submission, and the published form does not state an amount. Whether a specific repair counts as ordinary also stays with the village official. That official confirms it for a property.

How long review takes, and whether the form has changed. The application on the village site is a 2020 edition. Staff should confirm the current submission list. A deck near a flood area or large trees may add plans.
