The day the business changes shape: hiring your first employee in California

There is a job you cannot do alone. Not one you would rather not do alone, one you physically cannot: the drywall lift needs a second person, the pour has a window in it, the schedule the general contractor handed you assumes two bodies on site every day for three weeks.

So you decide to put somebody on. That decision is bigger than a rate and a start date, and not for the reason people expect. It is not that the paperwork is hard. It is that four separate things become true about your business on the same morning, all of them dated to your employee's first hour, and three of them have to already be in place before that hour arrives.

Here is the whole sequence, in the order it has to run, with a dated countdown you can copy onto a real start date.

Four things change, and three of them are backdated to day one

Your license now depends on a policy. The certification of exemption sitting on your CSLB file says you have no employees. From the first hour, it is false, and there is nothing behind it. A license is suspended by operation of law on the day cover lapses or the exemption stops being true (BPC s.7125.2), with no notice and no grace period. That is the single most expensive thing on this page, and it is worked through in workers comp for a California contractor.

You are an employer for payroll tax. More than $100 in wages in a calendar quarter makes you one, and you register with EDD within 15 days of crossing it (EDD). The accounts, the four taxes and the quarterly rhythm are in EDD employer registration.

You owe a written safety program. Every California employer maintains a written Injury and Illness Prevention Program (8 CCR 3203). Not a binder you buy afterward. A program that exists before anybody swings a hammer for you, because it is the document Cal/OSHA asks for first and you have 5 business days to produce it once they do.

Wage and hour law now applies to you. Daily overtime, meal periods, rest breaks, itemized wage statements, sick leave and final pay all arrive at once, and California is stricter on all of them than the federal floor you may have read about.

None of that is a reason to stay one person. It is a reason to spend two weeks getting it right, once, and then never think about it again.

The countdown, dated to a real Monday

Start date Monday 4 May 2026. Everything below is counted backward or forward from it.

Three weeks of lead time, and most of it is waiting on other people. The version of this that goes wrong is the one where somebody starts on Monday because the job needed them on Monday, and the comp policy, the EDD account and the safety program all get chased in the following fortnight while the exposure is already live.

The day one paperwork pack

Have these printed and signed on the first morning, in one folder, done once:

• Form I-9, employment eligibility verification, completed within 3 business days of the start of work.
• Federal Form W-4 and California Form DE 4, the two withholding certificates. They are separate forms with separate allowances and both are needed.
• The wage notice under Labor Code s.2810.5, given at hire, stating the rate, the pay basis, the regular payday, and your workers comp carrier.
• The workers comp time of hire pamphlet, handed over at hire, telling the employee how to report an injury and what happens next.
• Your IIPP, walked through rather than handed over, with the training signed for and dated.
• Emergency contact and direct deposit details, which are not statutory and are the two things you will need first in a real emergency.

Keep training and inspection records for at least a year (8 CCR 3203). The signature on a training sheet dated before the incident is worth more than any policy document you own.

Wage and hour, in the shape construction actually works

California counts overtime by the day, not only by the week, which is the rule that catches contractors coming from anywhere else.

Every pay period the employee gets an itemized wage statement carrying the gross, the hours at each rate, the deductions, the net, the pay period dates and your legal name and address (Labor Code s.226). This is not a formality, it is the document that decides most wage disputes, and a payroll system that produces it correctly on the first Friday is worth more than one you fix in month four.

Minimum wage is a jobsite address question in California, in the same way the sales tax rate is: the state rate is indexed, and a long list of cities and counties set their own higher floor that applies where the work is performed. Check the city you are working in, not the city you are based in.

Public work adds a whole layer. Prevailing wages apply on public works over $1,000, overtime is owed after 8 hours a day or 40 a week, you and every listed subcontractor must be registered with DIR to bid, and certified payroll goes in electronically at least monthly with records produced within 10 days of a written request. If any part of your first year involves a school district, a city or Caltrans, read DIR registration and certified payroll before you bid rather than after you win.

The safety program is the part that keeps the job open

The IIPP is not the whole of Title 8, and the pieces that touch a small crew hardest are the ones with numbers attached.

• Tailgate meetings at least every 10 working days (8 CCR 1509), with the topic and the attendees written down.
• Fall protection above 7.5 feet in construction (Title 8), which is a nine foot ladder, a low roof edge and a scaffold platform, not just the tall work.
• Heat, outdoors: shade available when the temperature exceeds 80 degrees, high heat procedures at 95 degrees with construction named in the standard, and one quart of drinking water per employee per hour (8 CCR 3395). Indoors, the standard starts at 82 degrees (8 CCR 3396). What that looks like on a real jobsite is in heat illness prevention for California construction.
• Permits before the work, not during it: trenches 5 feet or deeper, work above 36 feet, and demolition all need a Cal/OSHA permit. Cave in protection starts at 5 feet, and a trench needs a means of egress at 4 feet, within 25 feet of lateral travel.
• Reporting a death or serious injury within 8 hours (8 CCR 342).
• The OSHA 300A summary posted from February 1 to April 30 each year (Title 8).

Building the program itself, in the form Cal/OSHA expects to be handed within 5 business days, is in the IIPP guide for contractors.

What the person actually costs, and where that goes in your price

The employer side state payroll tax is smaller than the anxiety around it. Unemployment Insurance at 3.4 percent for a new employer and the Employment Training Tax at 0.1 percent both run on the first $7,000 of wages only (EDD), so $238 plus $7 is $245 per person per year and then it stops. State Disability Insurance and personal income tax are withheld from your employee's wages and remitted, so they are never your money.

The real cost of the hire is elsewhere: the workers comp premium on the classification they work in, the federal employer taxes, the paid sick leave, the hours you pay for that are not on a job, and the truck, phone and tools that come with a second person. That total is your loaded labor rate, and it is the number a first hire either quietly destroys or comfortably supports, depending on whether you built it before the start date or guessed at it afterward.

Build it properly. Gross wage, plus employer taxes, plus comp premium, plus non productive hours, divided by the hours you actually bill, then marked up for overhead and profit. The markup and margin calculator is free and needs no signup, and running your current price through it with a second person's burden loaded in is a fifteen minute exercise that changes what you bid on next. The full build is in what to charge as a California contractor.

Pick the start date, then count backward

Everything on this page is knowable three weeks ahead of time, which is the quiet advantage in it. The contractor who plans a first hire on a calendar starts Monday with a live policy, a filed certificate, an open payroll account, a written safety program and a signed folder. The contractor who hires on Friday for Monday spends the next quarter making all five of those things true retroactively, with the exposure already running.

Same hire, same person, same rate. Different business.

On AEC Stack there is no monthly subscription. The platform fee is 2.5 percent of each invoice processed through the platform, so the jobs your new hire helps you finish are the ones that carry the cost of the system that tracks them.

Choose the Monday you want them to start, count back three weeks, and put the six dates from the countdown table into your calendar today. Then open a working business file and keep the policy dates, the payroll account and the first job they work on in one place.
