These are counts of establishments physically operating in the county, not listings, so they are the supply side a feasibility study measures demand against. County Business Patterns counts private establishments with paid employees in March 2023, while the Quarterly Census of Employment and Wages above counts every unemployment-insured employer, public ones included, as a 2024 annual average, so the two establishment and employment counts differ.

The average approval of $654,836 sits well above the median of $260,000, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 14.9 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

The county's own community in the status book, unincorporated Summit County (community 080290), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Summit County in radon zone 1, a predicted average indoor radon screening level greater than 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. The best Community Rating System class among the county's communities is 7, which carries a flood insurance premium discount for policies written in that community. 80.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
