How to Start a Cleaning Business in Illinois

Starting a cleaning business in Illinois is straightforward compared to many other states, and the barrier to entry is low. Illinois has no statewide business license for cleaning companies, which means you can launch faster than you might expect. However, there are still critical steps you need to complete, especially if you want to operate in Chicago or certain suburbs, and you should not skip insurance and bonding.

With 34,602 solo janitorial businesses already operating in Illinois as of the 2022 Census, the market is established and competitive. That does not mean there is no room for you. It means there is proven demand. This guide walks you through exactly what you need to do to start a cleaning business in Illinois legally, from your first week through your first customers.

What You Need Before Starting

Before you file any paperwork, gather the essentials. Unlike some service businesses, a cleaning operation does not require expensive start-up inventory, but you do need the right tools and protective equipment.

Materials and Equipment

• Commercial-grade vacuums (2 to 3 units for reliability)
• Mops, buckets, and cleaning solution dispensers
• Microfiber cloths and cleaning towels (replace every 30 to 60 days)
• Disinfectants and surface cleaners (EPA-approved for commercial use)
• Floor buffers or polishers if offering floor care services
• Personal protective equipment: gloves, safety glasses, masks, aprons
• A reliable vehicle for transporting equipment and staff
• Cleaning supply storage system for your home or office

Business Setup Essentials

• A dedicated phone number for the business
• A business email address
• A simple website or social media presence
• A system for scheduling and invoicing (spreadsheet or cleaning software)
• A business checking account (separate from personal funds)

Startup costs for equipment, supplies, and initial marketing depend on whether you start as a solo operator or hire staff immediately.

How to Start a Cleaning Business: The Steps

Step 1: Decide Your Business Structure

Choose whether to operate as a sole proprietorship, an LLC, or a corporation. Most cleaning business owners start as sole proprietors or LLCs. A sole proprietorship requires no formal filing with the Illinois Secretary of State and has no filing fee, but it offers no legal separation between you and the business. An LLC provides liability protection and is still affordable: the Illinois Secretary of State charges $150 to file Articles of Organization, with standard processing in 10 business days.

For most small cleaning operations starting with one or two people, a sole proprietorship is simpler and cheaper. As you grow, converting to an LLC later makes sense. If you expect to hire employees immediately, forming an LLC adds protection without much extra cost.

Step 2: Register Your Business Name with the Secretary of State (If Not a Sole Proprietor Using Your Name)

If you form an LLC, your business name is protected when you file your Articles of Organization. You can file online at https://apps.ilsos.gov/llcarticles/index.jsp. The filing takes 10 business days for the standard fee ($150) or 24 hours for $250 total.

If you are a sole proprietor operating under a different name than your own (say, "Best Clean Illinois" instead of "John Smith Cleaning"), you need to file an Assumed Business Name certificate with the county clerk of any county where you operate. This does not give you exclusive rights to the name. The statutory county filing fee is $5, but counties add their own charges (Cook County Clerk charges $50), and you must publish notice in a newspaper once a week for 3 consecutive weeks.

Step 3: Get an Employer Identification Number (EIN)

Apply for a federal Employer Identification Number (EIN) from the IRS, even if you are a sole proprietor and do not plan to hire employees right away. It takes 10 minutes and costs nothing. Apply online at https://www.irs.gov/ein. An EIN makes opening a business bank account easier and looks more professional to customers.

Step 4: Obtain Local Business Licenses and Permits

This is where Illinois gets local: there is no statewide cleaning business license, but many cities and suburbs require one. The rules vary significantly depending on where you operate.

Chicago. If you operate in Chicago, you need a Limited Business License. As of 2026, the cost is $500 for a two-year term. You apply through the City of Chicago Business Affairs and Consumer Protection (BACP). Confirm processing times and business address requirements with BACP when you apply.

Suburban areas. Suburbs have different rules. Palatine charges $99 for a service business license or $12 for a home occupation license if you work from home. Bolingbrook charges $65 or more for a service business license or $55 for a home occupation license. Many smaller suburbs charge little or nothing. Contact your city or village clerk to confirm what applies to you. If you serve multiple suburbs, you may need licenses in each municipality where you maintain a regular location or office.

Downstate and smaller towns. Most downstate Illinois communities do not require a specific cleaning business license. However, always check with your local city or village clerk before launching. Having the wrong information costs you more time than a quick phone call.

Step 5: Register with the Illinois Department of Revenue

If your cleaning business will have any retail or service transactions subject to sales tax, register with the Illinois Department of Revenue. Illinois has a 6.25 percent state sales tax. Illinois sales tax applies to sales of goods, not to cleaning services, so registration matters mainly if you sell products to customers or hire employees.

Register for free at https://tax.illinois.gov/businesses/registration.html using MyTax Illinois. The process takes one to two business days online or four to six weeks by mail. You will receive a Certificate of Registration if needed for your service type.

Step 6: Obtain Bonding

Illinois does not require janitorial bonding by law, but many commercial and corporate customers will require it. Bonding protects your customer if any of your staff steals or damages property. Janitorial bonds come in different coverage amounts, and premiums depend on the amount and your history. Contact a surety bond broker or your insurance agent to get a quote. Without bonding, you will lose most commercial opportunities.

Step 7: Get Workers Compensation Insurance

Illinois requires workers compensation insurance from the moment you hire your first employee. You cannot legally operate with employees without it, and penalties for non-compliance include hefty fines and business shutdown. Shop for coverage before you hire. Premiums are based on payroll and job classification. Get quotes from three to five carriers before committing.

Step 8: Set Up a Business Bank Account

Open a separate checking account for your cleaning business using your EIN. This keeps business and personal finances separate, simplifies bookkeeping, and protects you if a customer disputes a charge or claims damage. Most banks offer free or low-cost business checking accounts. Bring your EIN letter, a photo ID, and your sole proprietorship documents or LLC Articles.

Step 9: Get Liability Insurance

General liability insurance covers accidental damage to customer property. If you slip while cleaning and break a client's lamp or damage their floor finish, liability insurance pays for it. Most commercial clients require proof of liability coverage before they sign a contract. Premiums depend on your services, limits, and claims history. This insurance is separate from bonding and workers compensation.

Step 10: Set Your Pricing and Launch

Research what competitors charge in your market: residential cleaning is often priced per visit or per hour, while commercial janitorial contracts are usually bid per square foot or as a monthly retainer. Price low enough to win customers but high enough to cover your costs, insurance, bonding, and profits.

How to Start a Cleaning Business in Chicago: Extra Steps

If your focus is Chicago, remember that you need the Limited Business License ($500 for two years) in addition to the state-level registrations. Chicago is more heavily regulated than most of Illinois. Also, Chicago has home occupation rules for home-based businesses, so verify that you can operate from your address before investing in equipment.

Tips and Common Mistakes to Avoid

Tip 1: Do Not Skip Bonding

Janitorial bonding sounds like an extra cost, but it is your entry pass to commercial work. Without it, you are limited to residential and small-business customers. Bonding is an investment that pays for itself in the first few commercial contracts.

Tip 2: Price Correctly From Day One

Undercutting competitors to win early customers is tempting but costs you profit and reputation. Once customers expect low pricing, raising rates is nearly impossible. Price fairly based on your market, experience level, and operating costs.

Tip 3: Get Everything in Writing

Use a simple service agreement for every customer, even one-time jobs. Specify what work is included, the price, the schedule, and what happens if cancellations occur. This prevents disputes and protects both you and your customer.

Tip 4: Verify Local Requirements Early

Many cleaning business owners wait until they have their first customer to check licensing rules, then discover they are operating illegally. Call your city clerk in week one. Fifteen minutes of homework saves months of problems.

Common Mistake 1: Mixing Personal and Business Money

Operating without a separate business bank account makes it impossible to track profit, complicates taxes, and looks unprofessional to customers. Open a business account before your first invoice.

Common Mistake 2: Assuming No Tax Obligation

Cleaning income is taxable. Many solo proprietors think they owe nothing because they are small. You owe federal income tax and Illinois state income tax (4.95 percent) on all net profit. Underreporting income leads to IRS audits and penalties.

Common Mistake 3: Hiring Without Workers Comp

Do not hire your first employee without workers compensation insurance in place. If an employee is injured, you face massive liability and legal consequences.

Expected Results and Next Steps

With proper setup, you can launch a cleaning business in Illinois in two to four weeks. Your first month should focus on landing customers, not on perfecting operations. Start with friends, family, and referrals, then move to online review platforms like Google, Yelp, and Facebook once you have a few satisfied customers.

Expect your first three to six months to be slower than later months. Growth typically accelerates as customers refer you and your online reviews accumulate. You can scale by hiring staff once demand is steady.

Before starting your cleaning business, consult with a qualified attorney about liability and business structure, a CPA about tax obligations specific to your situation, and your local city or village clerk about licensing requirements in your area. Rules change, and your specific circumstances may require decisions that go beyond this general guide.

Illinois has no state-level barriers to starting a cleaning business, which is a significant advantage. Use that advantage to move fast, but do not skip the local and legal details. Follow the ten steps above, get bonded, get insured, and launch. The cleaning business market in Illinois is large enough for new entrants who show up professionally and deliver consistent results.
