California Carpentry Class Codes 5403 vs 5432 and the $46.00 Threshold

Quick answer: 5403 vs 5432 in California

5403 is the low-wage carpentry code and 5432 is the high-wage code. For policies incepting on or after September 1, 2026, the split moves from $41.00 to $46.00 per hour — a $5.00 jump, the largest of any California dual-wage trade. The approved pure premium rates effective 9/1/2026 are $12.075 for 5403 and $5.321 for 5432, so the low-wage code costs 127% more per $100 of payroll. That is the widest gap in the construction table, wider than roofing.

The carpenters who just became low-wage

This is the part that catches contractors out, and it is specific to carpentry because the threshold moved further than anywhere else.

A carpenter earning $43.00 an hour was a high-wage employee under the old $41.00 threshold and was reported in 5432. From September 1, 2026 the threshold is $46.00, so the same person at the same wage doing the same work is now reported in 5403.

Nothing about the risk changed. The cost did. At a 1.00 mod over 2,000 hours, that employee workers comp goes from about $4,661 to about $10,384 — an increase of $5,723, or 123%. At a 1.75 mod the same worker goes from roughly $8,157 to $18,173. On a crew of ten carpenters in that wage band, at a 1.75 mod, that is about $100,000 of additional annual premium for no change in payroll.

If a renewal quote came back and nobody can work out why, this is very often the reason. Check which code the exposure sits in before concluding the market has turned.

Which code is which

5432 — high wage. CARPENTRY — including the installation of interior trim, doors and cabinet work in connection therewith — employees whose regular hourly wage equals or exceeds $46.00 per hour — N.O.C.

5403 — low wage. Same phraseology, ending does not equal or exceed $46.00 per hour.

The WCIRB footnote on 5432 is unambiguous: assignment is subject to verification at the time of final audit, and payroll for anyone not shown to earn $46.00 or more shall be classified as 5403, Carpentry.

As with every dual-wage class, the test runs employee by employee on the regular hourly wage. Overtime premium, bonuses and per-diem do not count toward the threshold.

Rate history

Effective date	5403 (low wage)	5432 (high wage)
9/1/2026	$12.075	$5.321
9/1/2025	$11.330	$5.420
9/1/2024	$10.930	$4.840

When the raise pays for itself

Compare total cost per hour — wage plus workers comp — not the premium line alone. At a 1.00 mod, paying $46.00 in 5432 costs $48.45 an hour all-in.

Current wage in 5403	All-in cost	Versus raising to $46.00
$40.00	$44.83	Raise costs $7,235/yr
$42.00	$47.07	Raise costs $2,752/yr
$43.00	$48.19	Raise costs $511/yr
$44.00	$49.31	Raise saves $1,731/yr
$45.00	$50.43	Raise saves $3,972/yr
$45.99	$51.54	Raise saves $6,191/yr

Per 2,000-hour FTE. Break-even is about $43.23 per hour at a 1.00 mod.

A worse mod lowers the break-even

Experience mod	Break-even wage
0.90	$43.48
1.00	$43.23
1.25	$42.63
1.50	$42.05
1.75	$41.51
2.00	$41.00
2.50	$40.03

At a 1.75 mod a carpenter at $45.99 costs $55.71 an hour all-in. At $46.00 they cost $50.28 — $10,850 per FTE per year for one cent of wage.

Mod cleanup takes three years. Reclassification takes one payroll run. If the mod itself is the problem, that is a separate placement question.

Four classification carve-outs for carpentry

• Shingle roofing and insulation installation stay in carpentry — but only if performed by the same employer doing the carpentry on new construction or additions at the same job or location. All other roofing is separately classified as 5552/5553.

• Concrete forms — making, erecting or stripping them goes to the appropriate concrete classification, not carpentry.

• Cabinet, fixture or interior trim installation goes to 5146(1) — but only if the employer performs no rough carpentry at the same job or location. Do both and it all stays in carpentry.

• Prefabricated doors, door frames or pre-glazed windows go to 5107, again only where there is no rough carpentry at the same location. And light-gauge cold-formed steel stud framing is not carpentry at all — it is 5632/5633, Steel Framing, which carries its own $46.00 threshold.

What else lands on the same renewal

September 1, 2026 is a crowded date: all sixteen dual-wage thresholds move, the advisory pure premium level rises 10.4%, and the experience rating eligibility threshold goes to $11,700. For carpentry the threshold move alone is the biggest single factor, so read the exposure detail by class code before blaming the market.

Two things to pull before the renewal meeting: the payroll split between 5403 and 5432 on the expiring term versus the quoted term, and a list of employees within a few dollars of $46.00. That second list is where the decisions are.

One honest caveat

These are WCIRB approved pure premium rates — advisory benchmarks, not the rates any carrier charges. California is an open-rating state; every insurer files its own rates and applies its own schedule and experience modifications. The shape of the 5403/5432 gap holds across the market because the loss data underneath is the same, but the exact break-even for a given account depends on that carrier filed rates and the client mod. Run it on the real quote.

Placing California carpentry and framing accounts

CPR Business Solutions is a wholesale workers compensation broker and MGA built around high-mod and hard-to-place accounts. If a carpentry or framing client has just seen payroll reclassify from 5432 to 5403, has a mod above 1.50, or has been non-renewed after an audit, that is the account we want.
