Philadelphia ties OSHA training to two things the city controls: contractor licenses and permitted job sites.
Contractor license: one OSHA 30 supervisor
To get a Philadelphia contractor license, at least one supervisory employee must have completed an approved OSHA 30-hour construction safety and health course within five years of the application or renewal date. That supervisor can only count for one company.
This is the general Contractor License. Electrical, plumbing, fire-suppression and complete-demolition work fall under specialized trade licenses, which have their own requirements, so check the license that matches your trade.
At renewal, if the city already accepted that supervisor's OSHA 30, the contractor can instead show 30 hours of approved construction or demolition safety continuing education completed in the previous five years.
Job sites: OSHA 10 for everyone
The Department of Licenses and Inspections requires every worker on a permitted construction or demolition site to have OSHA 10 construction training or an approved equivalent, with proof kept at the job site.
Planning around the five-year window
The license rule creates a hard date. Record your designated supervisor's OSHA 30 completion date, and plan either a new course or 30 hours of continuing education before the five-year mark. If that supervisor leaves, you need another qualified person before your next renewal.
In the tracker, add the OSHA 30 with an expiry five years after completion, so you get reminders well ahead of license renewal.
Two rules, two owners
Philadelphia's requirements come from the Department of Licenses and Inspections (L&I), and they attach to two different things:
| Contractor license | Permitted job sites | |
|---|---|---|
| Who | The licensed company | Every worker on the site |
| Training | One supervisory employee with OSHA 30 Construction | OSHA 10 Construction or an approved equivalent |
| Time limit | OSHA 30 completed within five years of application or renewal | None stated for the OSHA 10 |
| Renewal option | 30 hours of approved safety continuing education in the previous five years | Not applicable |
| Where proof lives | With the license application | At the job site |
A company can meet one rule and still fail the other. A licensed contractor with a qualified supervisor is still out of compliance if a laborer on a permitted site has no OSHA 10 proof on site.
The designated supervisor, in practice
The license rule names a single person. That creates a dependency many small contractors only notice at renewal time.
Pick someone who will stay. If your only OSHA 30 supervisor leaves, the company loses the person who qualifies the license. Before the next renewal you need another supervisor with OSHA 30 within five years, or a supervisor whose OSHA 30 the city already accepted and who has the continuing education.
One company only. A designated supervisor can only count for one licensed company. If you share a superintendent with a related company, each license needs its own qualifying supervisor.
Track the five-year date. The rule is "within five years" of the application or renewal date. If your supervisor took OSHA 30 in April 2022 and your license renews in June 2027, the course is more than five years old at renewal. Plan either a new OSHA 30 or the 30 hours of continuing education before then.
Worked timeline
| Event | Date |
|---|---|
| Supervisor completes OSHA 30 Construction | April 2022 |
| License issued using that OSHA 30 | June 2022 |
| Five years from OSHA 30 completion | April 2027 |
| License renewal due | June 2027 |
| Action needed | Before renewal: new OSHA 30, or 30 hours of approved safety continuing education completed since June 2022 |
In a tracker, enter the supervisor's OSHA 30 with a five-year reminder date. It is one of the few cases where putting an "expiry" on an OSHA card makes sense, because the city's license rule creates one.
Proof at the job site
L&I's contractor requirements say proof of OSHA 10 training must be kept at the job site. The simplest approach:
- Keep a folder or binder in the site trailer with copies of every worker's card.
- Or keep a digital list the foreman can open on a phone, with photos of each card.
- Update it the day a new worker arrives, including subcontractor and agency workers.
Inspectors can ask for proof during a site visit. A foreman who can show it in a minute keeps the visit short.
Specialized trade licenses
Electrical, plumbing, fire suppression and complete demolition contractors work under specialized trade licenses in Philadelphia. Those licenses have their own requirements, which can include their own safety training rules. If you hold one of these licenses, read the requirements for that license on the L&I website rather than relying on the general contractor license rules. Workers on permitted sites still need the OSHA 10 proof.
Demolition work
Philadelphia tightened its rules for demolition after the 2013 building collapse on Market Street. Demolition contractors face additional licensing, site safety and supervision requirements. If your work includes demolition, check L&I's current demolition requirements before starting. The OSHA 10 rule for workers still applies.
A Philadelphia checklist
For the license
- Name your designated supervisor and record their OSHA 30 completion date.
- Set a reminder well before five years from that date.
- If the supervisor leaves, qualify a replacement before your next renewal.
- Keep continuing education certificates if you plan to use the renewal option.
For each permitted site
- Collect OSHA 10 Construction proof for every worker before they start.
- Keep copies at the site, on paper or on a phone.
- Check subcontractor and agency workers on day one.
- Do not let anyone work without proof on site.
Common Philadelphia mistakes
- Thinking the supervisor's OSHA 30 covers the crew. Each worker needs OSHA 10.
- Missing the five-year date. The license rule is the one place where an OSHA card's age matters.
- Keeping proof only at the office. The rule says at the job site.
- Sharing a supervisor between companies. Each license needs its own.
- Using the general license rules for a specialized trade. Check the trade license.
Philadelphia and nearby jurisdictions
Pennsylvania does not have a statewide OSHA 10 law that we track, so outside Philadelphia the requirement usually comes from the contract or general contractor. Across the river, New Jersey does not have a general statewide OSHA 10 statute either, though public owners and GCs often require it. If you also work in New York, the New York OSHA 10 guide and NYC SST guide explain those rules. The state requirements checker compares all of them.
Tracking it in one place
Record each worker's OSHA 10 card with type, number, completion date, trainer and photos of both sides. For your designated supervisor, add the OSHA 30 with a five-year reminder. A crew card tracker keeps both rules visible and lets the foreman show proof from a phone on site.
What to tell a new hire on a Philadelphia site
A short script for the foreman on a worker's first morning:
- "Do you have your OSHA 10 Construction card? I need a copy before you start."
- "If you took the course recently and the card hasn't arrived, show me the certificate from the trainer or the online course."
- "If you don't have either, you can't work on this site today. We'll get you into a course."
- "Keep your card safe. If you lose it, only the trainer who gave the class can replace it, once, and only within five years."
Say it in the language the worker understands. Many Philadelphia crews include Spanish speakers, and OSHA 10 Construction is available in Spanish from authorized providers.
Budgeting for Philadelphia compliance
| Item | Typical cost |
|---|---|
| Online OSHA 10 Construction per worker | about $59–$90 |
| In-person OSHA 10 class | often $150–$300 per person |
| Online OSHA 30 Construction for the designated supervisor | about $160–$200 |
| In-person OSHA 30 | often $350–$600 |
| Paid training time | 10 hours per worker; 30 hours for the supervisor |
Prices vary by provider. The paid time usually costs more than the course itself. Most small contractors put the crew through OSHA 10 online and send one or two supervisors to OSHA 30, which also helps on jobs where general contractors require it. See how much an OSHA card costs.
When the city asks for proof
Proof can be requested at a site inspection, during a license application or renewal, or after a complaint. Keep three things ready:
- The site copy of every worker's OSHA 10 proof.
- The designated supervisor's OSHA 30 card or certificate with its completion date.
- Any continuing education certificates you plan to use at renewal.
With these in one folder or one tracker, a request becomes a five-minute task rather than a scramble.
