NAICS 236118

Overview

The North American Industry Classification System (NAICS) is the framework federal statistical programs use to classify business establishments so they can collect, analyze, and publish data on the U.S. economy. NAICS was jointly developed by the United States, Canada, and Mexico, first adopted in 1997 to replace the SIC system, and is revised on a five-year cycle; the current vintage is 2022. ¹
NAICS 236118 designates “Residential Remodelers,” covering establishments primarily engaged in remodeling activities on existing residential structures—work such as additions, alterations, reconstruction, and related maintenance and repair that is distinct from new home construction. It is part of NAICS Subsector 236, Construction of Buildings. ²
