The United States Small Business Administration (SBA) is increasing the small business size standards for 18 industries in North American Industry Classification System (NAICS) Sector 81, Other Services, and retaining the current standards for the remaining 30 industries in the Sector. As part of its ongoing initiative to review all size standards, SBA has evaluated every industry in NAICS Sector 81 to determine whether the existing size standards should be retained or revised.
