Joliet, Illinois, is the third-largest city in the state and sits in Will County, an area experiencing steady residential growth. The local market for deck building is strong, driven by older homes needing upgrades and new construction developments in neighborhoods such as Plainfield, Shorewood, and the newer subdivisions near I-55 and Route 6. Homeowners in Joliet prioritize outdoor living spaces, especially during the warm months from May through October, and many seek custom decks for entertaining, grilling, and increasing property value. The climate—with cold, snowy winters and humid summers—makes durable, well-constructed decks essential. Competition includes both established local contractors and a few regional companies, but there is room for a focused, service-oriented business that understands local building codes and homeowner preferences. Key materials popular in Joliet include pressure-treated lumber for affordability and composite decking (Trex, TimberTech) for low maintenance, as owners want to avoid the frequent staining required by wood in the Midwest freeze-thaw cycle.
Illinois does not require a statewide general contractor license for residential deck building, but you must register with the Illinois Department of Financial and Professional Regulation (IDFPR) as a roofing and siding contractor if your work involves any structural changes that affect the roof or siding. For deck builders, this typically does not apply unless you also build covered decks or pergolas that tie into the house roof. However, you must carry a valid business registration through the Illinois Secretary of State (for-profit LLC or corporation) and obtain an Employer Identification Number (EIN) from the IRS. If you hire employees, you must register with the Illinois Department of Employment Security and obtain workers’ compensation insurance as required by state law.
The City of Joliet requires a business license for any contractor operating within the city limits. You can apply online through the Joliet Business License Center. The fee is modest (around $100 annually), but you must provide proof of general liability insurance ($1,000,000 minimum is standard) and a completed application. Additionally, you need a contractor license from the Will County Building Division if you work outside Joliet city limits but within the county (most surrounding areas). For any deck project exceeding 200 square feet or attached to a structure, Joliet requires a building permit. Permits are obtained at the Joliet Community and Economic Development Department at 150 W. Jefferson Street. You must submit plans showing structural details, footings, and compliance with local building codes (based on the 2021 International Residential Code with amendments). Be prepared for a plan review fee (typically $50-$150) plus a permit fee based on the project’s value (often $100-$300). Failure to pull a permit can result in stop-work orders, fines, and difficulty selling the property later.
Beyond liability insurance, Illinois recommends a surety bond for deck builders who take large deposits. While not mandatory, many homeowners will request proof of a bond to protect their money. At minimum, carry $1,000,000 general liability and $500,000 workers’ compensation (if you have employees). Also, register with the Illinois Roofing Contractors Registration system if you install any roofing-adjacent structures (like a roof over a deck).
