How to Start a Bathroom Remodel Business in Illinois

Market Opportunity in Illinois

Illinois offers a strong market for a Bathroom Remodel business due to its aging housing stock, especially in the Chicago metro area where many homes were built before 1980. Statewide demand is driven by homeowners seeking to increase property value, improve accessibility, and modernize outdated spaces. The remodeling industry in Illinois has grown 4–6% annually over the last five years, with bathroom renovations consistently ranking among the top three home improvement projects by ROI. Population distribution is heavily skewed toward the Chicago metropolitan area (over 65% of the state's 12.5 million residents), but opportunities also exist in mid-sized cities like Rockford, Peoria, Springfield, and Champaign-Urbana where housing inventory is older and competition is lower. The biggest challenge is the competitive landscape in Cook County and the collar counties, where many contractors fight for high-value jobs. However, the trade-off is that average project budgets there are significantly higher. Suburbs like Naperville, Schaumburg, and Arlington Heights have lower saturation per capita compared to downtown Chicago, making them sweet spots for a new business.

State Licensing & Legal Requirements

Illinois does not have a statewide general contractor license, but you must comply with local municipal licenses and specific trade requirements. If you or your employees will perform plumbing work (common in bathroom remodels), you need a Plumbing License from the Illinois Department of Public Health (IDPH) or a local authority having jurisdiction (e.g., City of Chicago Plumbing License for work within the city). For electrical work, an Illinois Electrical License from the Illinois Department of Financial and Professional Regulation (IDFPR) is required if done in-house. You must register your business as an LLC or Corporation with the Illinois Secretary of State and obtain a Business Registration Certificate from the Illinois Department of Revenue. Many municipalities (e.g., Chicago, Naperville, Aurora) require a City Business License and a Home Improvement Contractor Registration through the City of Chicago Department of Business Affairs and Consumer Protection or equivalent local agency. You need at minimum: General Liability Insurance ($1M–$2M per occurrence), Workers' Compensation Insurance (mandatory in Illinois if you have any employees, and strongly recommended even as a sole proprietor to avoid personal liability), and often a Surety Bond ($10k–$25k) required by some municipalities for home improvement contractors. Verify all requirements at the city level where you plan to do most of your work—starting in a suburb like Naperville can be easier than dealing with Chicago's layered requirements.

Startup Costs

Vehicle: $8,000–$25,000 (used cargo van or pickup truck with ladder rack). Tools & Equipment: $3,000–$6,000 (tile saw, drill set, mixing tools, levels, safety gear, demo tools, dust containment). Licensing & Permits: $500–$1,500 (LLC filing, local business license, initial municipal registration, plumbing/electrical license fees if applicable). Insurance: $1,200–$3,000 per year (general liability plus workers' compensation if you hire help). Initial Marketing: $500–$2,000 (Google Business Profile setup, initial Google Ads $200–$500 for testing, yard signs $150–$300, flyers/ door hangers $200–$400, and basic website domain/hosting $150). Miscellaneous: $500–$1,000 (accounting software, job management app, phone, uniforms). Total startup range: $14,200–$39,000. Illinois-specific note: vehicle costs and insurance tend to be higher in the Chicago area due to the market and risk, so budget on the upper end if you operate in Cook County.

Revenue Potential in Illinois

Average job ticket for a bathroom remodel in Illinois ranges from $8,000–$15,000 for a standard mid-tier renovation (tub-to-shower conversion, new fixtures, tile work, and paint). In affluent Chicago suburbs (e.g., Highland Park, Lake Forest, Barrington), high-end remodels often run $25,000–$50,000. Downstate markets like Springfield or Peoria average $7,000–$12,000. To reach $5,000/month: bid and close just 1 small job (e.g., a partial bathroom refresh or tub replacement) per month at $5,000–$6,000 average. For $10,000/month: complete 1.5–2 full bathroom remodels monthly at $6,000–$8,000 each, or a mix of small and medium jobs. With efficient scheduling and a two-person crew, you can realistically scale to $15,000–$20,000/month
