Why this source was used
County Business Patterns provides establishment counts, employment, and payroll data by NAICS code and firm size. For NAICS 236118 (Residential Remodelers), CBP data shows the market is heavily dominated by firms with 1–4 employees, with very few large firms. This anchors the “highly fragmented” characterization of the renovation contractor market and the contrast with the more concentrated new-construction sector.
