Homeowners in Tulsa, Oklahoma often ask a mold company for its state license number. The honest answer surprises people: there isn't one to give. This post explains who regulates what, what you can check instead, and the Oklahoma rules that do apply to renters, sellers, permits and storm repairs.

Does Oklahoma require a license for mold remediation?
No. Oklahoma does not license mold inspectors or mold remediation companies. Oklahoma DEQ says the state has no licensing or certification program for mold testing or cleanup companies, and that preventing and cleaning up mold is ultimately the property owner's responsibility. General contractors also need no state license in Oklahoma, according to the Construction Industries Board (CIB).
That does not mean mold work is a free-for-all. Several other licenses, registrations and laws still apply to parts of the job, and they are the things worth checking.
Who regulates what
| Work or issue | Who handles it | What to ask for |
|---|---|---|
| Mold inspection, testing, remediation | No state license | Insurance certificate, written scope, references |
| Plumbing, electrical, mechanical (HVAC) | Construction Industries Board | The contractor's CIB license |
| Roofing | Construction Industries Board (registration) | The "OK" registration number on trucks and contracts |
| Home inspection | Construction Industries Board | CIB home inspector license (covers home inspection, not mold) |
| Asbestos abatement | Oklahoma Department of Labor | A Department of Labor asbestos license |
| Lead paint work in pre-1978 homes | Oklahoma DEQ | DEQ lead renovation (RRP) certification |
| Building and trade permits in Tulsa | City of Tulsa | Who pulls the permit, if one is needed |
| Contractor complaints and fraud | Oklahoma Attorney General | Complaint history, along with the BBB |
What you can check before you hire
- Liability insurance. Ask for a certificate sent from the insurer or agent, not a photo of one.
- CIB licenses for any plumbing, electrical or mechanical work, such as moving a water line or replacing an air handler.
- CIB roofing registration for roof repairs. Registered roofers carry at least $500,000 in liability insurance for residential work and show their "OK" number on vehicles, ads and contracts.
- Asbestos and lead. In homes built before 1980, ask whether suspect materials will be tested before tear-out. Asbestos licensing is through the Oklahoma Department of Labor; lead renovation certification for pre-1978 paint work is through Oklahoma DEQ.
- Complaint history with the Oklahoma Attorney General and the BBB.
- Industry training such as IICRC courses. Useful, but optional private credentials, not state licenses.
These checks matter in Tulsa because the housing is older than most: the city's median home was built in 1973, and 64.9% of homes predate 1980 (ACS 2024). See mold removal in Tulsa for how the work itself usually runs.
Do you need a permit for mold remediation in Tulsa?
Mold cleaning and small tear-out usually need no permit. Plumbing, electrical, mechanical, roofing and structural work generally do, and in Tulsa only licensed or registered contractors pull trade permits. Suburbs such as Broken Arrow, Owasso and Jenks run their own permit offices. If you are unsure, ask the company or the City of Tulsa permit center.
Oklahoma landlord and tenant rules on mold
Oklahoma's landlord-tenant law does not name mold, but it covers the leaks and broken systems that cause it. Oklahoma landlords must keep rentals fit and habitable and keep plumbing, heating, ventilating and air-conditioning in good working order (41 O.S. §118). If they don't, tenants must give written notice first. Oklahoma law then allows specific remedies, including ending the lease or, for health-related repairs costing up to one month's rent, a repair-and-deduct process after 14 days with an itemized statement (41 O.S. §121, as amended November 1, 2022).
Keep copies of every notice, photo and reply. For Tulsa property conditions you can also contact Tulsa 311. This is general information, not legal advice; talk to an Oklahoma attorney or Legal Aid Services of Oklahoma about your situation. More in Oklahoma renters' mold rights and on the rental and tenant mold page.
Selling a house with past mold or water damage
Oklahoma's Residential Property Condition Disclosure Statement, the standard OREC form, asks whether the property has been inspected for mold and whether there has been remedial treatment for mold. It also asks about flooding and storm runoff, water in the heating and air conditioning ducts, leaks, hail and wind damage, and insurance payments for damage that was not repaired. Keep inspection reports, remediation invoices and clearance results, and talk to your agent or attorney about how to answer.
Storm repairs and contract rules
Green Country storms bring door-knockers, so a few Oklahoma rules are worth knowing:
- Roofers may not offer to pay, waive or rebate your insurance deductible (59 O.S. §1151.30).
- A contract to be paid from a property insurance claim can generally be canceled within 72 hours after you receive a written denial of all or part of the claim (59 O.S. §1151.21).
- For sales made at your home, federal rules generally give you 3 business days to cancel.
- Get a written contract with no blank spaces, and don't pay a large amount upfront.
Report problems to the Oklahoma Attorney General. Our guide to hiring a mold remediation company in Oklahoma walks through the paperwork.
What about health departments?
There are no state or federal limits for mold in homes, and the Oklahoma State Department of Health says it does not have authority over mold complaints. Mold remediation is done by private companies. If someone in the home has symptoms, see a doctor.
Frequently asked questions
Does Oklahoma license mold inspectors or mold remediation companies?
No. Oklahoma DEQ says the state has no licensing or certification program for mold testing or cleanup companies. General contractors also need no state license. What you can check is liability insurance, CIB licenses for plumbing, electrical and mechanical work, CIB roofing registration, asbestos and lead credentials for older homes, and complaint history with the Attorney General and BBB.
Is there a mold law in Oklahoma?
There is no mold-specific licensing law. Mold questions fall under other rules: landlord duties in the Residential Landlord and Tenant Act (41 O.S. §118 and §121), the seller disclosure form, contractor and roofing rules, permits, and asbestos and lead programs. This is general information, not legal advice.
Are landlords responsible for mold in Oklahoma?
Oklahoma landlords must keep rentals fit and habitable and keep plumbing, heating, ventilating and air-conditioning in good working order (41 O.S. §118). Tenants must give written notice first; the law then allows specific remedies under §121. This is general information, not legal advice; talk to an Oklahoma attorney or Legal Aid Services of Oklahoma.
What does a CIB license mean for mold work?
The Construction Industries Board licenses plumbing, electrical and mechanical contractors and home inspectors, and registers roofers. None of those is a mold license. It matters when your job includes trade work, such as fixing a leaking line or an AC drain, because that part needs a CIB licensee and, in Tulsa, a permit pulled by one.
