  A business license is an annual tax for doing business
  within the City. The City of Grass Valley
  Business License Ordinance requires a business license for any business
  activity conducted in Grass Valley city limits. Business
  license taxes and fees help pay for City services such as roads,
  fire, police, and other community services. Business
  licenses are renewed annually at the beginning of each year.
