A union carpenter is not one job. Under the United Brotherhood of Carpenters (UBC), the same union card can lead to concrete formwork on a highway bridge, ceiling grid in a hospital, a millwright crew aligning a turbine, or a pile driving rig setting foundations before anyone else is on site. That range is the best thing about the UBC and the most confusing part for people trying to get in. This guide sorts out the crafts, the pay data, how the apprenticeship is structured, and how to pick the lane that fits you.
If you are still deciding whether a union is right for you at all, start with our merit shop vs. union comparison. This piece assumes you are leaning union and want to know what carpentry looks like inside it.
One union, many crafts: what a union carpenter can do
The UBC organizes by region, through regional councils and their locals, and each council trains for several distinct crafts. The North Atlantic States Regional Council of Carpenters lays out its lineup under the heading "One Trade, Many Crafts." Paraphrased, it looks like this:
| Craft | What the work involves | Typical setting |
|---|---|---|
| General carpenter | Forms for concrete, exteriors, roofs, scaffolding, plus trim and finish work | Commercial buildings, infrastructure |
| Residential carpenter | Framing, windows, doors, trim, cabinets, siding, roofing, drywall | Houses and multifamily |
| Interior systems | Metal stud framing, wall partitions, acoustical ceilings, access flooring, office furniture | Offices, schools, hospitals, often occupied |
| Floor coverer | Carpet, resilient, wood, laminate and sport surfaces; layout and estimating | Commercial and institutional interiors |
| Shop and millmen | Architectural millwork: trim, cabinetry, doors, stairs, displays, built in a shop on specialized machines | Fabrication shops |
| Millwright | Installing, aligning and repairing compressors, pumps, conveyors, turbines and production equipment | Power plants, auto, aerospace, food and pharma plants |
| Pile driver | Driving steel, concrete or wood piling, checking hammer performance and load capacity; some are commercial divers | Bridges, marine work, heavy foundations |
Not every council offers every craft. When you contact a training center, ask which crafts it runs apprenticeships for and whether you choose your craft when you apply. It is better to know which lane you want before you are on the list.
Union carpenter pay: what the federal data shows
The Bureau of Labor Statistics reports a median wage for carpenters of $60,580 a year, or $29.12 an hour (BLS, May 2025). The lowest-paid 10 percent earned under $40,410, and the top 10 percent earned more than $99,910. For comparison, the median for all construction trades workers was $58,150.
Where you work matters. In the same BLS data, carpenters in nonresidential building construction had a median of $63,780, while residential building construction came in at $60,600 and foundation, structure and exterior contractors at $58,790. Union carpentry tends to concentrate on commercial, institutional and heavy work, so the nonresidential figure is the more relevant reference point for most UBC members.
Two cautions. First, BLS does not split union from nonunion pay in these figures, and it does not count self-employed carpenters, who make up a quarter of the occupation. Second, a union carpenter's real compensation is the full package: hourly wage plus health and welfare, pension and annuity contributions, and training fund contributions. Those fringe dollars can be a large share of the total. To see what your local actually pays, get its current wage sheet and read it with our guide to reading a local's wage scale.
How the UBC carpenter apprenticeship works
BLS notes that most carpenters learn through on-the-job training or apprenticeships, and that apprenticeships are commonly sponsored by unions and contractor associations. Each year combines a set number of hours of technical instruction with paid work on job sites. Length and hours vary by program and region, which is why you will see different numbers from different councils.
The UBC apprenticeship runs on steps. You start at a percentage of the journey-level rate and move up as you complete hours on the job and the required classes. A UBC member profile on carpenters.org describes it plainly: everyone who completes each step moves up to a set pay rate. In that profile, a former childcare center director says she was out-earning her old job after about a year and a half and three steps. That is one person's experience, not a promise, but it shows how the structure works. Raises are tied to completed steps, not to whether a foreman likes you.
A few things to know before you apply:
- OSHA 10 is a baseline. BLS states that carpenters must complete the OSHA 10-hour safety course. Some programs build it into the first term; having it before you apply does not hurt.
- Pre-apprenticeship programs exist. Some locals run short programs to bring in new people, including targeted recruiting. The same carpenters.org profile mentions a pre-apprenticeship that UBC Local 745 used to recruit women.
- Math and drawing help. BLS recommends math and mechanical drawing courses. Expect to read plans, lay out work and calculate materials from the first month.
- You may change sites often. Construction jobs end, and apprentices can move between contractors and projects over the course of the program. Ask your training center how placement works between jobs.
Carpenter, millwright or pile driver: choosing your lane
The crafts reward different temperaments. Use this as a starting filter, then talk to the training coordinator and, if you can, journey-level members in each craft.
| If you like... | Look first at | Trade-offs to weigh |
|---|---|---|
| Big structures, outdoor work, seeing concrete go up | General carpenter (forms, heavy and highway) | Weather, early starts, heavy lifting, layoffs between pours |
| Precision, machines, troubleshooting | Millwright | Shutdown work can mean long shifts and travel; tight tolerances |
| Heavy equipment, marine work, foundations | Pile driver | Remote and waterfront sites; some roles involve diving |
| Clean interiors, steady indoor work, layout | Interior systems or floor coverer | Kneeling and repetitive motion; working around occupants |
| Fine woodworking and machinery in one place | Shop and millmen | Fewer shops than job sites; less variety of location |
Millwright work deserves a special note. The NASRCC description says some millwright tasks call for tolerances down to a thousandth of an inch. If you like the idea of plant equipment more than building structures, that is a strong reason to ask specifically about a millwright apprenticeship rather than a general carpentry one.
Where the work is: outlook for carpenters
BLS counted 889,700 carpenter jobs in 2025 and projects 4 percent growth from 2025 to 2035, about as fast as average, or roughly 35,000 added jobs. More important for someone entering the trade is the turnover: BLS expects about 62,800 openings each year, mostly from carpenters retiring or leaving the occupation.
BLS also flags a trend that matters for career planning. Modular and prefabricated components are reducing the need for some on-site framing. For a union carpenter, that cuts two ways. Residential framing is the most exposed. Formwork, interior systems, millwright work and pile driving are much harder to move into a factory. If you want long-term security, building skills in more than one of those areas is worth more than being the fastest framer on the crew.
How to become a union carpenter: a practical checklist
Each regional council sets its own process, but the path usually looks like this:
- Find your regional council and its training center. Search for the UBC regional council covering your state. The training center, not the hiring contractor, usually handles apprenticeship applications.
- Ask which crafts are open. Some crafts take applicants year-round; others open on a schedule. Ask how the waiting list works.
- Collect documents. BLS lists a high school diploma or equivalent as the typical requirement. A driver's license is often needed to reach job sites. Have transcripts, ID and any certifications ready.
- Get OSHA 10 if you can. It is required for the trade anyway.
- Brush up on math. Fractions, measurements and basic geometry come up constantly in layout.
- Consider a pre-apprenticeship. If your council offers one, it can be a shorter path to an apprenticeship slot.
- Be ready to interview. Our guide to interviewing with a union local covers what they tend to ask.
If you do not know anyone in the trade, that is common. See breaking into a union trade with no connections for the approach that tends to work.
The hard parts nobody puts on the brochure
BLS lists the common carpenter injuries: strains from overexertion and lifting, falls, slips and trips, and being struck by objects or equipment. The work involves lifting, standing and kneeling, sometimes in tight spaces, and outdoor crews lose days to weather. Schedules can shift with conditions, and evenings and weekends happen.
The union structure softens some of this. Pay steps are written down, training is ongoing, and you have a local and a training center behind you when one job wraps up. It does not remove the physical toll. Protect your knees and back early, take the fall protection training seriously, and plan for a career that may shift from field work toward foreman, superintendent or instructor roles over time. BLS lists first-line supervisor, lead carpenter and construction supervisor as common advancement paths.
Bottom line
Verdict: The UBC is one of the broadest doors into union construction. If you want variety, start in general carpentry. If you want precision and plant work, ask for millwright. If you want heavy civil and marine work, ask for pile driver. Whatever you choose, judge the opportunity by the local's total package and step schedule, not the BLS median, and pick a craft that will be hard to move into a factory.
