What Does NAICS Code 236118 Cover?
According to the official 2022 NAICS data, code 236118 covers establishments primarily responsible for the remodeling construction (including additions, alterations, reconstruction, maintenance, and repairs) of houses and other residential buildings, single-family and multifamily.
In simple terms, this code applies to any general contractor or builder whose main activity is improving existing homes. This includes:
- Addition, Alteration, and Renovation: Adding rooms or modifying existing residential layouts.
- Home Improvement: General remodeling projects like kitchen or bathroom upgrades.
- Fire and Flood Restoration: General contractors performing residential reconstruction after damage.
- Handyman Construction Services: Professional repair and maintenance for residential buildings.
- Porch and Sunroom Construction: Adding exterior living spaces to existing dwellings.
- Multifamily Renovation: Remodeling apartments, condominiums, and townhouses.
The important distinction here is residential buildings. If your primary focus is renovating offices, stores, or factories, you should use 236220 (Commercial and Institutional Building Construction).
