Is There a Pennsylvania Mold License? What the Rules Actually Require
No. Pennsylvania has no state license or certification for mold remediation or mold assessment. The state Department of Health says there are no federal or Pennsylvania regulations about mold. What does apply: home improvement contractors must register with the PA Attorney General, Gettysburg Borough requires a land use permit for projects in town, the historic district has its own review, and EPA lead-safe rules cover paint disturbed in homes built before 1978.
“Are you licensed for mold?” is a fair question, and in Pennsylvania the honest answer for every company is the same: there’s no such license to have. The state doesn’t license or certify mold remediation or mold assessment. That doesn’t mean there are no rules. It means the rules that apply come from other places: contractor registration, local permits, the historic district and federal lead-safe requirements.
What the state says
The Pennsylvania Department of Health’s mold fact sheet says it directly: there are no federal or Pennsylvania state regulations about mold. The state Department of Labor & Industry adds that Pennsylvania currently has no licensure or certification requirements for most construction contractors. Its short list of state-level exceptions includes crane operators, home improvement contractor registration with the Attorney General, manufactured housing installers, and asbestos and lead workers. Mold isn’t on it.
So if a company says it holds a “Pennsylvania mold license,” ask to see it, politely. What it may really have is an HIC registration, a private certification, or both. Those are worth having. They just aren’t a state mold license.
What does apply to a mold job
| Rule | Who sets it | When it applies |
|---|---|---|
| Home Improvement Contractor registration | PA Attorney General | Contractors doing $5,000 or more of home improvement work a year |
| Written contract and 3-day right to cancel | Same state law | Home improvement contracts over $500 |
| Consolidated Land Use Permit | Gettysburg Borough | Every project in the borough, per the borough |
| Certificate of Appropriateness | Borough, after HARB review | Exterior changes in the historic district, including historic window replacement |
| Lead-safe certification (RRP) | EPA | Paid work disturbing paint in pre-1978 homes, above minor-repair amounts |
This is a summary, not legal advice; the Attorney General’s office has the details. The registration and contract side is covered in how to check out a mold company. Townships around the borough have their own permit offices, so check with yours.
The historic district and old paint
Two things make Gettysburg different from a newer suburb. First, the borough’s historic district. Its review board looks at exterior work you can see from a street or alley, even when no building permit is required, and replacing historic windows needs approval. If a mold job traces back to a leaking window or a failed exterior detail, the fix may need that review before it happens.
Second, the age of the houses. Census figures show about 87% of the borough’s homes were built before 1980. The EPA’s Renovation, Repair and Painting rule says firms paid to disturb paint in housing built before 1978 must be certified, even sole proprietors. Inside, the minor-repair exemption is six square feet or less of painted surface per room. Cutting out a moldy section of painted drywall or plaster often goes past that. More on old-house work is in historic homes and mold, and the numbers are on the Gettysburg housing data page.
How other states handle mold licensing
| State | What it requires |
|---|---|
| New York | Licenses for mold assessors, remediators and workers since 2016, for jobs over 10 square feet; one licensee can’t assess and remediate the same project |
| Texas | Separate assessment and remediation licenses; small jobs exempt; same-project restriction |
| Florida | Licensing for assessment and remediation of growth over 10 square feet; an assessor can’t remediate a building their company assessed in the last 12 months, with an exception |
| Louisiana | A mold remediation license from the state contractor board on jobs over $7,500 |
| Pennsylvania | No mold license |
Those rules exist because of the conflict of interest. Pennsylvania leaves that choice to you, and the pros and cons are in should your inspector and your remediator be different companies.
The practical takeaway
With no license to lean on, the homeowner does the checking. Look up the registration, ask for insurance, read the contract, ask about lead-safe work in an older house, and ask who pulls any permit. I’m John Calhoun, and I’d rather you ask me all of that than assume. My mold remediation page lists what I do, and the overview of mold remediation in Gettysburg, PA covers how I approach a job.

Questions about mold rules in Pennsylvania
Do I need a permit for mold remediation in Gettysburg?
Gettysburg Borough says every project in the borough needs a Consolidated Land Use Permit, and projects covered by the state building code go to its code agency for plan review and inspection. Work in the historic district that changes the outside of a building can also need a Certificate of Appropriateness. Townships have their own rules. Under the state's home improvement law, your contract should say whether a permit is needed and who gets it, so ask before work starts.
Can a mold inspector also do the remediation in Pennsylvania?
Yes. Pennsylvania has no rule against it. Some states do: New York, Texas and Florida all bar the same licensee or company from assessing and remediating the same job, with some exceptions. In Pennsylvania, that choice is yours. If you want an independent check, you can hire one, and the trade-offs are covered in the guide on whether your inspector and remediator should be different companies.
Does the lead rule apply if I'm doing the mold cleanup myself?
The EPA's Renovation, Repair and Painting rule is aimed at firms paid to do work in pre-1978 housing, not owners working on their own homes. But the lead hazard doesn't care who's holding the knife. If you're cutting out painted drywall or plaster in an older house, treat the paint as if it contains lead until a test says otherwise, keep dust down, and read the EPA's lead pages before you start.
