Permit Requirements in Nacogdoches
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, mold remediation is regulated by the Texas Department of Licensing and Regulation (TDLR). A Mold Assessment Technician or Mold Remediator license is often required for any remediation project exceeding 10 contiguous square feet of water damage or mold growth. For larger projects — typically over 25 square feet — a licensed Mold Remediation Contractor may be required.
Local building permits in Nacogdoches may also be necessary if the remediation involves structural repairs, demolition, drywall replacement, or HVAC system modifications. Always check with the Nacogdoches Building Inspections Department to confirm what applies to your specific project.
When Permits Are Required
Permits and licensed remediation are typically required in the following situations:
- Mold growth covering more than 25 contiguous square feet (requires licensed contractor)
- Remediation that involves removing walls, ceilings, or flooring
- Work that includes HVAC modifications or duct cleaning due to mold
- Projects in commercial buildings, multi-family units, or public facilities
- Remediation following flood damage, sewage backups, or long-term leaks
- Any project where structural repairs are part of the mold recovery plan
- Work in rental properties where local landlord-tenant ordinances apply
Common Exemptions
Minor mold remediation work may not require a permit in certain situations, such as:
- Small areas of mold (under 10 square feet) that can be cleaned with household products
- Surface cleaning on non-porous materials without removal or demolition
- Routine maintenance that does not involve tearing into walls or structural components
- Property owner performing remediation on their own primary residence (though TDLR licensing may still apply for larger areas)
Important: Even if a permit is not required, following TDLR-recommended mold remediation practices is strongly advised for health and safety.

Permit Process
Step 1: Identify the Scope of Work
Assess the size of the affected area and determine if structural components are involved. If the mold covers more than 10 contiguous square feet, you'll likely need a licensed professional. Measure carefully and document the damage with photos.
Step 2: Consult a Licensed Mold Assessor
Before any remediation work begins, a licensed Mold Assessment Technician or Company may need to inspect and assess the property. This step identifies the type of mold, the extent of contamination, and helps determine if a local building permit is needed.
Step 3: Check with Nacogdoches Building Inspections
Contact the Nacogdoches Building Inspections Department to ask whether your specific project requires a building permit. Be prepared with details about the scope of work, the size of the affected area, and whether any demolition or structural changes are planned.
Step 4: Submit Permit Application (if required)
If a permit is needed, submit the required application along with any supporting documentation such as the mold assessment report, contractor licenses, and a work plan. Permit fees are typically based on the estimated cost or scope of the project.
Step 5: Schedule Inspections
After remediation work begins, you may need to schedule one or more inspections. A post-remediation clearance inspection by a licensed Mold Assessment Consultant is often required to verify that the mold has been properly removed and the area is safe.
Step 6: Obtain Final Clearance and Close-out
Once all work is completed and passes inspection, obtain a certificate of completion or clearance letter. Keep all permits, inspection reports, and contractor licenses on file — these may be needed for insurance claims or future property transactions.
Compliance Tips
- ✓ Always verify that your mold remediation contractor holds a valid TDLR license — you can check license status on the TDLR website before hiring.
- ✓ Get a pre-remediation mold assessment from a separate company than the remediator to avoid conflicts of interest, as recommended by TDLR guidelines.
- ✓ Document everything: take photos before, during, and after remediation, and keep copies of all permits, licenses, and inspection reports.
- ✓ If your mold issue is related to flooding or a plumbing leak, address the moisture source first — otherwise, remediation may not be effective long-term.
- ✓ Ask your contractor if they carry liability insurance and workers' compensation coverage specific to mold remediation work.
- ✓ Don't skip the post-remediation clearance inspection — it's the only way to confirm the mold has been properly removed and the area is safe to occupy.
Special Considerations
HOA Rules
If your property is in a Nacogdoches homeowner's association (HOA), check your CC&Rs before starting mold remediation. Some HOAs require advance written approval for exterior work, dumpster placement, or visible repairs. HOAs near Stephen F. Austin State University or in planned communities may have stricter guidelines. Get HOA approval in writing to avoid fines or work stoppages.
Zoning
Zoning regulations in Nacogdoches may affect mold remediation work, particularly for commercial or multi-family properties. Work that changes building use, involves outdoor equipment (like dehumidifiers or dumpsters), or alters the building footprint may require zoning compliance review. Verify your property's zoning designation with the Nacogdoches Planning and Zoning Department.
Historic Properties
Nacogdoches is the oldest town in Texas and has several historic districts including the downtown Historic District and the Washington Square Historic District. Properties in these areas must follow additional preservation guidelines. Any mold remediation that affects historic materials, plaster, original woodwork, or building exteriors may require approval from the Nacogdoches Historic Preservation Commission. Use contractors experienced with historic building materials.
