The first thing Cal/OSHA asks for is a document, and you have five days to produce it

An inspector walks onto your site on a Tuesday morning. Maybe somebody complained, maybe there was an accident on the block, maybe the trench you have open is visible from the street. The conversation does not start with your ladders or your harnesses. It starts with a request for your written Injury and Illness Prevention Program, and the clock on producing that document is five business days (8 CCR 3203).

Contractors who learned the rules anywhere else get caught here, because the book they studied is the wrong book. California runs its own program. Cal/OSHA and Title 8 of the California Code of Regulations are the rules on your job, not the federal standards, and the differences are not cosmetic. The written safety program is required of every employer with no size exemption. Fall protection in construction starts lower than the federal trigger. Three completely ordinary construction activities need a permit before you begin. The heat rules have no federal equivalent at all.

None of it is difficult. All of it is one document, one habit and one phone number, built once and reused on every job after that. Here is the whole of it, with the section behind each number.

The program they ask for has eight parts, and none of them need a consultant

Section 8 CCR 3203 requires every California employer to establish, implement and maintain a written Injury and Illness Prevention Program. Every employer. One employee is enough to trigger it, and there is no small business exemption from the requirement itself.

The written program has to answer these eight things:

Notice what is not in that list. No page count, no format, no approved template, no filing anywhere. Cal/OSHA does not hold a copy of your program. The requirement is that the document exists, that it fits the work you actually do, and that the name at the top belongs to somebody who works for you.

The way this goes wrong is almost never a bad program. It is a business that bought a binder for a different trade, never opened it, and cannot answer a single question about it when the inspector reads the hazard list aloud.

Five business days, counted the way an inspector counts them

The request is usually verbal and on site. The production window is five business days (8 CCR 3203), which is short enough that "it is on the laptop at the office" is not a plan and long enough that a business with its file in order never feels it.

Take a real week. An inspector arrives Tuesday 14 July 2026 and asks for the program that morning.

Five business days across a normal week lands eight calendar days out, because the weekend is not in the count. The contractor who keeps the program as a PDF on their phone closes this out on the afternoon it is asked for.

That is the practical shape of the rule: it is not a test of your safety record, it is a test of whether your paperwork exists today. Which means it is entirely winnable in advance, and it is the cheapest thing on this page to get right.

The records are the proof, and one year is the floor

Inspection records and training records are kept for at least one year (8 CCR 3203). A signed, dated training sheet from before an incident is worth more than any policy document you own, because it is the only thing that shows the instruction happened before the injury rather than after it.

A business with fewer than 10 employees gets a lighter version: inspection records kept only until the hazard is corrected, and a log of the instructions given rather than a full record of every session (8 CCR 3203). Use the relief if you qualify, but understand what you are giving up. On a job where something goes wrong, a crew that signed for the tailgate on the specific hazard involved is in a different position from one whose foreman remembers mentioning it.

Two more construction specific items sit alongside the program itself, in the construction safety orders rather than the general ones:

• Tailgate meetings at least every 10 working days (8 CCR 1509), run by the supervisor with the crew. Write down the date, the topic and who was there. Ten working days is a fortnight of normal work, so in practice most contractors run them weekly and never have to count.
• A Code of Safe Practices at the job site (8 CCR 1509), available to the crew rather than filed at the office. It is job specific, and it is the second document an inspector asks about.

If you are about to put your first person on the payroll, the program has to exist before their first hour rather than after it. The sequence for that, with the comp policy and the payroll accounts in the right order, is in hiring your first employee in California.

Three ordinary jobs need a permit before you start

This is the one that surprises people, because in most states these are just Tuesday. Under Labor Code s.6500, a Cal/OSHA permit is required before the work begins for:

The permit is applied for and issued by the Division, not the city, and it is separate from your building permit. A city inspector signing off your shoring says nothing about the Cal/OSHA side.

Read that as a scheduling item. A permit applied for during preconstruction costs you an email. A trench already open without one costs you the trench, the crew standing around it, and the conversation about why. Demolition contractors should run it as a standing step in job startup, alongside the classification questions in the C-21 demolition guide.

The four numbers on a trench and the one on a roof

Excavation is where Title 8 gets specific and where the numbers do not match the ones people quote from memory.

• Cave-in protection starts at 5 feet. Shoring, shielding, sloping or benching, unless the excavation is entirely in stable rock (8 CCR 1541).
• A means of egress at 4 feet. A ladder, stair or ramp in the trench, within 25 feet of lateral travel from any worker (8 CCR 1541). One foot shallower than the protection trigger, which is exactly why it gets skipped.
• A permit at 5 feet, as above (Labor Code s.6500).
• Fall protection in construction above 7.5 feet (Title 8). That is a nine foot stepladder, a low roof edge, a single scaffold platform. Contractors used to the federal six foot trigger tend to assume California is more permissive here. It is not the same rule, and the exposures it catches are the everyday ones rather than the dramatic ones.

Four numbers. Write them on the inside of the job box lid and the majority of your Title 8 exposure on a residential or light commercial job is handled.

Eight hours to make the call

A death or a serious injury or illness is reported to the nearest Cal/OSHA district office within 8 hours (8 CCR 342). Not the next business day. Not after you have spoken to your insurer or your attorney. Eight hours from when you knew or reasonably should have known.

Work the clock on a real one. A laborer takes a fall at 3:40 pm on Thursday 16 July 2026 and goes to hospital. The report is due by 11:40 pm the same night, which means it is made from the site or the hospital parking lot, not from the office on Friday morning. The number goes in your phone, in the IIPP, and on the Code of Safe Practices posted at the job. On a crew where the foreman has it and the owner does not, the call still gets made.

The report is not the workers compensation claim. That has its own paperwork and its own clock, and it is in workers comp for a California contractor.

One more calendar item that catches people once a year: the OSHA 300A annual summary is posted from February 1 to April 30 (8 CCR 14300 and following). It is a printed page on the wall for three months, and it is a standing citation for anyone who forgets it exists.

You can be cited for a hazard that is not yours

California codifies the multi-employer worksite doctrine at Labor Code s.6400(b). On a site with several employers, an employer can be cited as the one who created the hazard, the one whose employees were exposed to it, the one responsible for correcting it, or the one with general control over the site.

For a subcontractor, the practical read is that a hazard you walked past is not automatically somebody else's problem, and for a general contractor it is that control over the site carries exposure to everything on it. Neither of those is a reason to police the job. It is a reason to write down the hazard you saw and who you told, on the day you saw it. That note is the difference.

Build it once, then stop thinking about it

Everything on this page is a fixed target. The program has eight parts, the production window is five business days, records run a year, tailgates run every 10 working days, permits attach to three activities, and the serious injury call is eight hours. Nothing on that list changes with the job, the client or the season. That is the quiet advantage in it: a contractor who spends one afternoon writing a real program for the work they actually do never spends another afternoon on it, while the one who plans to sort it out later has the same afternoon waiting for them on the worst possible day.

The heat rules are the exception to that, in the sense that they run on a temperature rather than a calendar, and they are the standard California enforces hardest in construction. Read heat illness prevention on a California construction site before the first hot week, not during it. If you handle solvents, silica or lead in front of anyone who is not on your payroll, Proposition 65 for contractors is the other one-afternoon setup on this list.

On AEC Stack there is no monthly subscription. The platform fee is 2.5 percent of each invoice processed through the platform, so the job file that holds your program, your tailgate log and your permit dates is paid for by the jobs that actually get paid.

Write the program this week, with your name in the responsibility box and your real hazards in the hazard box. Then open a working business file and keep the tailgate dates and training sheets with the jobs they belong to, so producing them takes five minutes instead of five days.
