  • For-profit and independently operated business
  • Federal Tax Identification Number (TIN)

    • The gross receipts averaged over the most recent three-year tax period must not exceed the small business size standard set by U.S. Small Business Administration (SBA) for your company’s primary line of business. Size standards are set by the U.S. Small Business Administration (SBA) and can be found at Table of Size Standards. Using the North American Industry Classification System (NAICS) codes, the SBA has determined the gross receipts or number of employees a business can have and still be considered small. The certification reviewer will use the NAICS code most relevant to the company’s primary line of business to evaluate its business size.
    • An overall business size standard cannot exceed $30.4 million in gross receipts over a three-year average.
  • Primary Owner(s) personal net worth not to exceed $1.32M
    • The majority and controlling owner(s) must complete a Personal Financial Statement. An eligible owner's personal net worth cannot exceed $1.32M. This calculation will exclude the owner's primary residence and the value of their ownership in the applicant business. This calculation will include any other properties or businesses held by the owner.

  • If Washington State requires a professional license for the type of work your company performs, the eligible owner must possess the applicable professional license to be certified by the County.
  • For example, in order for a firm to be certified to do electrical work, the eligible owner must be a licensed electrician. However, if a firm is seeking certification to provide IT Consulting services, the eligible owner does not need to possess any professional licenses because Washington State does not require an IT Consultant to be professionally licensed.
  • This rule also applies if a professional license is required to operate any equipment necessary for the firm's activities. For example, the eligible owner of a dump trucking firm must possess a Commercial Driver's License.
