If you have a strong business plan and you're ready to cover a new niche in the market, it's worth starting a cleaning business. Cleaning services are also extremely in demand and always essential, so it's likely you'll always have some money coming into the business.

Limited liability company (LLC) A limited liability company is the most common business structure for cleaning businesses that choose not to be sole proprietors. An LLC offers protections similar to those of a corporation, but comes with different tax and legal requirements.

On average, small cleaning businesses make anywhere between $35,000-50,000 a year. As your business expands, you make a more sizable $100,000 a year. Your earnings will ultimately depend on whether you have a consistent stream of customers and are managing your resources well.
