Class Code 5403
Workers Comp (NCCI)Carpentry — NOC
Carpentry "not otherwise classified" — commercial framing, multifamily work over the 5645 thresholds, and general carpentry that doesn’t fit a more specific code. Typically rated higher than finish work, lower than roofing.
Operations commonly included
- Commercial and multifamily framing
- Carpentry over three stories
- General carpentry with no more specific code
- Blocking, backing, and rough carpentry on commercial jobs
Commonly classified elsewhere
- Detached 1–2 family dwellings ≤3 stories (5645)
- Cabinet and trim installation (5437)
- Furniture/shop work (shop codes)
Real-world example
A crew framing townhomes and a strip-mall buildout bills all of it to 5403 unless job records isolate qualifying 5645 residential work.
⚠️ Common audit mistake Assuming "mostly residential" earns 5645 without records — the burden is on the insured; absent documentation, auditors default to the higher code.
State variation: Bureau states vary; check the state’s carpentry code family before quoting multi-state work.
Rated on: Gross payroll, per $100.
