Nonproductive Time Is the Compliance Blind Spot
If you pay crews by the piece, you probably have a clear system for productive work. Roofer tears off 15 squares, gets paid for 15 squares. Drywall hanger finishes 30 sheets, gets paid for 30 sheets.
But what about the time your crew spends loading the truck at the shop? Driving between job sites? Sitting through a safety meeting? Waiting for an inspector to show up?
That is nonproductive time. Your workers are not producing pieces, but they are still on the clock. And under federal law — and especially under California law — you have to pay them for it. How you pay them is where most contractors get it wrong.
What Counts as Nonproductive Time
Let me be specific about what falls into this category. Nonproductive time is any time a piece rate worker is under your control but not actively performing piece work. Here are the most common examples in construction:
- Travel between job sites (not commuting from home to the first site — that is generally not compensable)
- Loading and unloading materials at the shop or on site
- Setup and cleanup at the beginning and end of each day or each job
- Safety meetings and toolbox talks
- Waiting for inspections or permits
- Weather delays when workers are required to remain on site
- Equipment breakdowns when workers cannot perform piece work but have not been sent home
- Training sessions
- Administrative tasks like filling out paperwork or attending company meetings
The key test is whether the worker is under your direction and control. If you told them to be there, it is compensable time. Period.
The Federal Rule: Nonproductive Time Counts Toward Hours Worked
Under the FLSA, nonproductive time is part of the worker's total hours worked for the week. This matters for two reasons.
Reason 1: Minimum wage compliance. You must ensure that a piece rate worker's total earnings for the week, divided by total hours worked (including nonproductive time), meets or exceeds the federal minimum wage of $7.25 per hour. If nonproductive time pushes the total hours up enough that the effective hourly rate drops below minimum wage, you owe a top-up.
Reason 2: Overtime calculations. Nonproductive hours count toward the 40-hour weekly overtime threshold. If a worker logs 38 hours of productive piece work and 5 hours of nonproductive time, that is 43 total hours — and you owe overtime on those 3 hours over 40.
Here is how the federal approach works in practice.
Federal Example
Maria is a drywall finisher paid $0.45 per square foot. This week:
- She finished 3,200 square feet of drywall (productive time: 36 hours)
- She spent 4 hours in travel between sites
- She spent 2 hours in safety meetings
- Total hours worked: 42 hours
Step 1: Calculate piece earnings.
3,200 sq ft x $0.45 = $1,440.00
Step 2: Check minimum wage.
$1,440.00 / 42 hours = $34.29 per hour — well above minimum wage. No top-up needed.
Step 3: Calculate overtime.
42 total hours - 40 = 2 overtime hours
Regular rate: $1,440.00 / 42 = $34.29
Overtime premium: $34.29 x 0.5 x 2 = $34.29
Step 4: Total pay.
$1,440.00 + $34.29 = $1,474.29
Notice that the 6 hours of nonproductive time (travel and safety meetings) are included in the total hours, which affects both the regular rate calculation and the overtime trigger. Under the federal approach, Maria does not receive a separate payment for nonproductive time — it is baked into the overall calculation.
But some contractors fail to count those 6 hours at all. They only count the 36 productive hours. In that scenario, Maria would not trigger overtime (36 hours is under 40), and the minimum wage check would show a higher effective rate ($1,440 / 36 = $40/hour). Both numbers would be wrong because nonproductive hours were excluded.
The California Rule: Separately Compensated (AB 1513)
California is a different animal. Under AB 1513 and Labor Code Section 226.2, nonproductive time must be separately compensated — you cannot just roll it into the piece rate calculation.
This is a critical distinction. In California, paying a flat piece rate and hoping the math works out for nonproductive time is not enough. You must pay nonproductive time as a separate line item on the pay stub.
California Requirements
For each pay period, California requires:
- Separate compensation for nonproductive time at no less than the applicable minimum wage (currently $16.50/hour in California, with some cities higher)
- OR at the average piece rate — whichever produces a higher amount for the worker
- This must appear as a separate line item on the wage statement
The average piece rate is calculated as: total piece rate earnings / total productive hours.
California Example
Carlos is a roofer in Los Angeles paid $80 per square. This week:
- He completed 18 squares (productive time: 38 hours)
- He spent 3 hours in travel between job sites
- He spent 1 hour in a safety meeting
- Total nonproductive time: 4 hours
- Total hours worked: 42 hours
Step 1: Calculate piece earnings.
18 squares x $80 = $1,440.00
Step 2: Calculate average piece rate.
$1,440.00 / 38 productive hours = $37.89 per hour
Step 3: Determine nonproductive time rate.
California minimum wage: $16.50/hour Average piece rate: $37.89/hour
Use the higher amount: $37.89/hour
Step 4: Calculate nonproductive time pay.
$37.89 x 4 hours = $151.56
Step 5: Calculate overtime.
Total hours: 42. Overtime hours: 2.
For overtime calculation, combine all earnings: Total straight-time earnings: $1,440.00 + $151.56 = $1,591.56 Regular rate: $1,591.58 / 42 = $37.89 Overtime premium: $37.89 x 0.5 x 2 = $37.89
Step 6: Total pay.
$1,440.00 (piece earnings) + $151.56 (nonproductive time) + $37.89 (overtime premium) = $1,629.45
And on Carlos's pay stub, the piece earnings and nonproductive time compensation must appear as separate line items. You cannot just show "$1,629.47 — piece rate." California's Labor Code Section 226 requires that breakdown.

Other States with Strict Rules
California gets the most attention, but other states have their own requirements around nonproductive time and piece rate pay:
Washington: Requires that piece rate workers receive at least minimum wage for all hours worked, with clear record-keeping requirements. Washington's minimum wage is among the highest in the country.
Colorado: The Colorado Overtime and Minimum Pay Standards (COMPS) Order requires employers to pay for all time workers are required to be on premises or at a prescribed work site.
Oregon: Requires separate record-keeping for productive and nonproductive hours and has its own minimum wage structure that varies by region.
New York: Requires detailed wage statements and has strong enforcement around piece rate minimum wage compliance.
Even in states without California-style separate compensation requirements, the federal rule still applies: nonproductive time counts toward total hours for minimum wage and overtime purposes.
Practical Tips for Tracking Nonproductive Time
Knowing the rules is one thing. Actually tracking nonproductive time in the field is another. Here is what works.
Separate Time Categories
Your time tracking system needs at least two categories: productive time and nonproductive time. When a worker clocks in, they should be able to indicate what type of work they are doing.
If you are using paper timesheets, add a column. If you are using software, make sure it supports the distinction. This is not optional in California — you need this data for the pay stub.
Define Nonproductive Time for Your Crews
Do not assume your workers know what counts as nonproductive time. Spell it out. Create a list specific to your operation:
- Travel time between sites: nonproductive
- Loading materials at the shop: nonproductive
- Waiting for the inspector: nonproductive
- Actual roofing/framing/drywall work: productive
Post it in the shop. Review it at your next safety meeting. Make sure foremen understand it so they can help crews log it correctly.
Track It Daily, Not Weekly
The biggest tracking failure I see is waiting until the end of the week to reconstruct nonproductive time. By Friday, nobody remembers that they spent 45 minutes waiting for an inspection on Tuesday.
Log it the same day it happens. Better yet, log it in real time. When the crew transitions from productive to nonproductive work, mark it.
Use the California Method Even If You Are Not in California
Here is a practical tip: consider paying nonproductive time separately even if your state does not require it. Why?
- It creates clearer records in case of an audit or wage claim
- It makes your pay stubs more transparent, which builds trust with workers
- It ensures you are compliant if you ever expand into a state that requires it
- It forces you to actually track nonproductive time, which many contractors skip entirely
Our California piece rate calculator can help you run the numbers for separate compensation, regardless of which state you are in.
What Happens When You Get It Wrong
The penalties for mishandling nonproductive time vary by state, but here is what you are looking at:
Federal: Back wages for minimum wage violations plus liquidated damages (double the back pay). If overtime was miscalculated because nonproductive hours were excluded, add overtime back pay on top.
California: Up to $100 per pay period per employee for wage statement violations (Labor Code 226). Plus back pay for unpaid nonproductive time. Plus potential waiting time penalties of up to 30 days' wages if a terminated employee was not paid correctly.
Class action risk: Nonproductive time violations tend to affect every piece rate worker in the company the same way. That makes them ripe for class action lawsuits. One worker figures out they were not paid for travel time, an attorney gets involved, and suddenly every current and former employee is part of the claim.
I have seen contractors face claims covering two to three years of back pay across entire crews. The numbers get large fast.
Common Scenarios and How to Handle Them
Morning Load-Up at the Shop
Your crew meets at the shop at 6:30 AM to load materials, then drives to the job site arriving at 7:15 AM. The 45 minutes at the shop plus drive time is nonproductive time. Clock starts at 6:30, not 7:15.
Mid-Day Site Change
Crew finishes one job at noon, drives 30 minutes to the next site. That 30 minutes is nonproductive time under your control. It counts.
Weather Delay
Rain hits at 2 PM. You tell the crew to wait it out because the forecast says it will clear by 3 PM. That hour of waiting is nonproductive time. If you send them home, their day ends and you pay through the time they were released.
End-of-Day Cleanup
Crew stops producing at 4:30 PM but spends 30 minutes cleaning up the site, securing materials, and loading the truck. That 30 minutes is nonproductive time.
The Bottom Line
Nonproductive time is real time. Your workers are giving it to you, and the law requires you to account for it. Ignoring it does not make the obligation go away — it just creates a ticking liability.
Track it. Pay for it. Document it. The cost of doing it right is small compared to the cost of doing it wrong.
