Business laws include all municipal, state, and federal laws that regulate businesses and commerce. For example, at the local level, some cities may require businesses operating within their boundaries to obtain a business license. Additionally, cities may have ordinances that restrict the location of businesses to areas zoned for commercial use. At the state level, a business will have to comply with a state's labor and employment laws when hiring employees. This includes wage and hour regulations, as well as any workplace safety laws regulating the business. Additionally, the state may also regulate certain businesses (e.g., contractors, attorneys, doctors, cosmetologists, etc.) by imposing licensing requirements. Federal laws that may impact a business include antitrust laws, federal labor and employment laws, and immigration laws.
