Class code 5651 — Carpentry — Detached Dwellings
Carpentry work limited to detached one- or two-family residential structures.
This classification is a narrower version of dwelling carpentry, limited specifically to detached one- or two-family homes rather than any residential structure. Crews frame walls and roofs, set trusses, and complete finish carpentry such as trim, doors, and stairs, but only on standalone houses that don't share walls with neighboring units. Some states apply this distinction to separate the risk profile of single detached builds from attached or higher-density residential work.
Payroll includes framers and finish carpenters working the full arc of a detached home build, from foundation framing through trim-out. As with general dwelling carpentry, laborers handling material and site cleanup on the same crew are usually included, while office staff and estimators are kept separate.
The injury profile mirrors other dwelling carpentry work: falls from unfinished framing and ladders drive the more serious claims, while saws, nail guns, and lumber handling generate the bulk of day-to-day cuts and strains. Because detached homes are built on individual lots rather than dense multi-unit sites, crews also deal with more material staging and vehicle traffic around the job site.
