Finish Carpentry: What It Covers and Where Rough Ends

What is finish carpentry?

Finish carpentry is the trade that installs the visible woodwork in a building after the structure is framed and the walls are closed. It covers door and window casing, baseboard, crown, wainscot, stair parts, built-ins, closet systems and hardware. The work is judged on fit and on how it looks, not on load.

Rough carpentry ends where finish carpentry begins

California writes the boundary into its licensing rules, and it is the clearest published version of the split. Under Title 16 of the California Code of Regulations, a C-5 Framing and Rough Carpentry contractor “performs any form work, framing or rough carpentry necessary to construct framed structures,” including sub-flooring, siding, roof decking and sheathing.

A C-6 Cabinet, Millwork and Finish Carpentry contractor “makes cabinets, cases, sashes, doors, trims, nonbearing partitions and other items of finish carpentry by cutting, surfacing, joining, gluing and fabricating wood or other products…” and also “places, erects, and finishes such cabinets and millwork in structures.”

That is a California rule, not a national one. Carpentry licensing is state and local, and several states do not license it at all. But the line it draws is the one every job site uses: rough carpentry builds what holds the building up, finish carpentry installs what you look at.

What the scope actually covers

The finish carpentry list

Door casing and jambs. Window casing, stool and apron. Baseboard and shoe. Crown and chair rail. Wainscot. Stair treads, risers, skirtboards, newels, balusters and handrail. Built-in shelving. Closet systems. Door and cabinet hardware.

Where millwork and cabinetmaking split off

Millwork is the manufactured product, the profiles and doors and cabinets produced in a shop. Cabinetmaking is building those pieces. Finish carpentry is fitting and installing them on site, which is why California folds all three into one classification.

What the labor data says, honestly

There is no federal occupation called finish carpenter. The Standard Occupational Classification puts the work inside Carpenters, SOC 47-2031, and O*NET lists Finish Carpenter and Rough Carpenter side by side as reported titles for that one code.

So a wage figure here describes carpenters as a whole. The May 2025 national median is $29.12 an hour, series OEUN000000000000047203108, against a mean of $31.55 across 670,090 carpenters. The 25th percentile is $23.32, the 75th $36.94.

Those are wages employers pay employees. The survey excludes the self employed, so a one truck trim shop is not in it.

A worked example on one bedroom

Take a 12 by 14 foot bedroom with one door and one window. The perimeter is twice 12 plus twice 14, so 52 linear feet. Subtract 3 feet for the door opening, leaving 49 feet of baseboard.

Casing a standard interior door takes about 17.5 feet a side, two legs and a head, so 35 feet for both sides, hall side included. The window with stool and apron runs about 18 feet. Total trim is 49 plus 35 plus 18, so 102 linear feet.

Put your own hours against it. At 8 hours for one carpenter, the May 2025 median of $29.12 gives $232.96 in wage, or $2.28 a foot in wage alone. The hours are your number, not a published one. Material, burden, truck and margin sit on top.

Where finish carpentry shows up on a job

When it happens in the sequence

After drywall, after primer, and usually after flooring so base sits on the finished floor. Trim before paint on stain grade, after the first coat on paint grade.

What gets inspected

Most of it, nothing. Trim is not a code inspection item the way framing is. The exception is stair parts: handrails, guards and balustrades are code regulated and they are on the final inspection like anything else. The rest the client inspects at eye level, which is a harder gate, and it lands on the punch list more than any other trade.

Common mistakes on trim bids

Bidding a room instead of a takeoff

Count linear feet by profile. Base, casing, crown and rail install at different speeds, and a single room number hides the expensive ones.

Treating stain grade like paint grade

Stain grade allows no filler and no caulk to hide a joint. Same footage, more hours, and the difference belongs in the bid before the job starts.

Price a finish carpentry scope in four steps

1. Take off by profile

   Linear feet of base, casing, crown and rail counted separately, never as one room number.

2. Set the grade

   Paint grade or stain grade changes the hours far more than the footage.

3. Quote material at the yard

   No allowed publisher states a trim price, so get the yard number in writing.

4. Build labor off a wage

   Start at the published carpenter median, then add burden, truck and margin.
