Permit Requirements in Port Arthur
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, a Mold Assessment Company license from TDLR is required for any mold remediation project exceeding 25 contiguous square feet of mold growth. Licensed professionals must oversee the work, and in many cases, a permit is needed if the remediation involves:
- Removing drywall, insulation, or other building materials
- Structural repairs after mold removal
- HVAC system cleaning or modification related to mold
- Work triggered by water damage restoration
Permits are primarily tied to the construction and repair aspects — not the mold cleanup itself. If your remediation project requires tearing into walls, replacing subflooring, or repairing structural damage, a building permit from the City of Port Arthur's Development Services Department is typically required.
When Permits Are Required
A permit is most often required when:
- Mold remediation involves removing or replacing drywall, framing, subflooring, or insulation
- The project includes structural repairs or modifications to load-bearing elements
- HVAC system modifications are needed (ductwork replacement, air handler repairs)
- The mold issue stems from plumbing leaks or roof leaks that require repair permits
- The affected area exceeds 25 contiguous square feet (triggers TDLR licensing requirements)
- The property is a commercial building — commercial mold remediation often falls under stricter permitting rules
- Post-remediation verification is required (clearance testing by an independent assessor)
Common Exemptions
A permit may not be required when:
- The affected area is smaller than 25 square feet (minor, spot-level mold issues)
- The mold is on non-structural surfaces like tile, glass, or metal (cleaning only)
- The work is simple cleaning with no removal of building materials
- The property owner is performing the work on their own single-family residence (owner-occupied exemption — but proceed with caution)
- The remediation involves only HEPA vacuuming and surface cleaning with no demolition
Important: Even when a permit isn't required, Texas law still requires licensed mold assessors and remediators for projects over 25 square feet. Always verify with local authorities before starting work.

Permit Process
1. Assess the Mold Situation
Hire a licensed Mold Assessment Consultant to inspect the property and determine the extent of the mold growth. This professional will provide a written assessment and remediation protocol, which may be needed for permit applications.
2. Determine Permit Requirements
Contact the City of Port Arthur's Development Services Department to discuss your specific project. Bring your mold assessment report and explain what structural work (drywall removal, framing repairs, etc.) is planned. They will tell you exactly what permits are needed.
3. Hire a Licensed Mold Remediation Contractor
In Texas, mold remediation must be performed by a TDLR-licensed Mold Remediation Contractor for projects over 25 square feet. Ensure your contractor holds an active license and is familiar with Port Arthur's local permitting requirements.
4. Submit Permit Application
If structural work is involved, submit a building permit application with the city. This typically includes a detailed scope of work, the mold remediation protocol, contractor information, and any applicable fees. Plans may be required for larger projects.
5. Schedule Inspections
Once permitted, the city may require inspections at key milestones — typically after demolition but before reconstruction, and again after the final repairs are complete. A post-remediation clearance test by an independent assessor is also strongly recommended.
6. Obtain Final Approval
After all work passes inspection and post-remediation clearance testing confirms the mold has been properly removed, you'll receive final sign-off. Keep all paperwork for insurance claims and future property disclosures.
Compliance Tips
- ✓ Hire a TDLR-licensed Mold Remediation Contractor — it's the law in Texas for projects over 25 square feet, not just a best practice.
- ✓ Get a pre-remediation mold assessment from an independent consultant (not the same company doing the remediation) to avoid conflicts of interest.
- ✓ Always pull permits for structural repairs — skipping them can lead to fines, stop-work orders, and issues when selling your home.
- ✓ Keep a paper trail: save all mold assessment reports, remediation protocols, permits, inspection results, and clearance testing documents.
- ✓ Address the moisture source first — mold remediation without fixing the leak or humidity problem is almost guaranteed to fail.
- ✓ Post-remediation clearance testing by an independent assessor protects you and confirms the property is safe to reoccupy.
- ✓ Check with your insurance company — many homeowners policies cover mold remediation from sudden water damage but may require specific documentation.
- ✓ Don't cut corners on containment — proper negative air pressure, HEPA filtration, and plastic barriers protect your family from airborne mold spores during work.
Special Considerations
HOA Rules
If your Port Arthur home is part of a Homeowners Association (HOA), check your CC&Rs before starting mold remediation work. Some HOAs require advance notice or approval for exterior modifications, dumpster placement, or construction staging. Prompt mold remediation is generally protected, but keeping your HOA informed helps avoid disputes.
Zoning
Zoning regulations in Port Arthur may affect mold remediation if the property is a commercial or multi-family building. Certain zones have restrictions on work hours, debris containment, and waste disposal. Check with the City's Planning and Zoning Department to ensure your remediation plan complies with local land use rules.
Historic Properties
Port Arthur has several historic neighborhoods and properties. If your home or building is in a designated historic district, any structural changes tied to mold remediation may require approval from the Port Arthur Historical Commission. Use mold-compatible repair materials that maintain the historic character where possible.
