General Rules
In Texas, mold remediation is regulated at the state level by the Texas Department of Licensing and Regulation (TDLR). While local building permits may not always be required specifically for mold removal, state licensing requirements often apply depending on the size and scope of the remediation.
For any mold remediation project involving more than 25 contiguous square feet of mold growth, Texas law requires the work to be performed by a TDLR-licensed mold remediation contractor. Additionally, a licensed mold assessment consultant may be needed to perform testing and clearance inspections.
When Permits Are Required
A state-licensed mold remediation contractor is typically required when:
- The affected area exceeds 25 contiguous square feet of mold growth
- The mold is a result of water damage from flooding, leaks, or sewage backup
- The property is being sold or refinanced and mold is discovered during inspection
- The remediation involves HVAC systems or ductwork
- Structural materials (drywall, framing, insulation) need to be removed
- The project is part of a larger renovation or construction permit
Local building permits may also be required if the remediation involves structural repairs, drywall replacement, or electrical work as part of the mold abatement process.
Common Exemptions
Small-scale mold cleanup may not require a licensed contractor if:
- The affected area is smaller than 25 contiguous square feet (e.g., a small patch in a bathroom)
- The mold is on non-porous surfaces that can be cleaned with appropriate products
- The homeowner is performing the work on their own primary residence (though caution is strongly advised)
Important: Even if exempt from licensing, proper safety protocols (PPE, containment, disposal) should always be followed. Always verify current requirements with TDLR and local San Patricio County officials.
✅ Usually Required

- ✓ Major structural changes

Permit Process
1. Determine Scope of Work
Assess the size of the mold-affected area. If it exceeds 25 contiguous square feet, Texas law likely requires a licensed mold remediation contractor. Have a licensed mold assessment consultant inspect and test the property first.
2. Verify Contractor Licensing
Confirm that any mold remediation company you hire holds a valid TDLR license. You can verify licensing through the TDLR website. Licensed contractors must follow strict protocols for containment, air filtration, and waste disposal.
3. Obtain a Mold Assessment
A licensed mold assessment consultant typically conducts pre-remediation testing to identify mold types, extent of contamination, and moisture sources. This assessment helps guide the remediation plan.
4. Submit Permits (if applicable)
If your mold remediation involves structural repairs, drywall replacement, or electrical/HVAC work, check with the San Patricio County or City of Portland building department for any required construction permits.
5. Remediation Work
Licensed contractors follow TDLR-approved protocols including containment barriers, negative air pressure, HEPA filtration, proper removal and disposal of contaminated materials, and antimicrobial treatment.
6. Clearance Testing
After remediation, a licensed mold assessment consultant (independent from the remediation company) performs post-remediation testing to confirm the mold has been successfully removed and the area is safe for reoccupancy.
Compliance Tips
- ✓ Always hire a TDLR-licensed mold remediation contractor for any project over 25 contiguous square feet — it's not just smart, it's the law in Texas.
- ✓ Keep a licensed mold assessor separate from the remediation company to avoid conflicts of interest. Texas law encourages this distinction for reliable clearance testing.
- ✓ Document everything: photographs, contracts, lab results, clearance reports, and disposal records. This protects you during property sales or future insurance claims.
- ✓ If mold is from a recent leak or flood, address the moisture source first. Permits for plumbing or roof repairs may be needed separately before remediation begins.
- ✓ Check with your homeowner's insurance policy. Some policies cover mold remediation but may require you to use licensed professionals to validate the claim.
- ✓ Never mix bleach with ammonia or other cleaners when attempting DIY mold cleanup — it creates toxic gases. When in doubt, consult a professional.
Special Considerations
HOA Rules
If you live in a Portland neighborhood governed by a Homeowners Association (HOA), you may need to notify them before work begins. Some HOAs have architectural review rules that apply to exterior repairs or visible changes to the property. Check your HOA covenants for any pre-approval requirements related to remediation work, especially if it involves exterior demolition or construction.
Zoning
Zoning regulations in Portland primarily affect the use of the property rather than interior mold remediation. However, if the remediation requires dumpsters, equipment staging, or exterior containment structures on the property, check with the City of Portland's planning or code enforcement office for any temporary zoning allowances or right-of-way permits.
Historic Properties
Portland does not have a designated historic district of significant size, but if your property is near any historically designated sites in San Patricio County, additional review may be required. Generally, interior mold remediation does not trigger historic preservation rules, but exterior structural changes might. Verify with the local planning department if your property has any historic designations.
