Know when you need a permit to ensure your project is legal and safe
General Rules
In the state of Texas, mold remediation contractors must hold a valid TDLR license to perform remediation work on properties larger than 25 contiguous square feet. While the state license covers the contractor, local building permits from Nacogdoches County or the City of Martinsville may also be required if the remediation involves demolition, structural repairs, or changes to your home's mechanical systems (HVAC, plumbing, or electrical).
When a permit is typically needed:
- Mold remediation involving removal of drywall, insulation, or structural materials
- Projects requiring HVAC system modification or duct replacement
- Work that includes new construction, framing, or drywall installation after remediation
- Remediation in commercial buildings or multi-family dwellings
When Permits Are Required
Permits are most often required in these specific situations:
- Structural mold remediation — If the mold has affected load-bearing walls, subflooring, or roof structures, a building permit is typically required before repairs begin.
- HVAC-related mold issues — Mold in ductwork or air handling systems often requires mechanical permits for cleaning, repair, or replacement.
- Commercial properties — Nacogdoches County and Martinsville may require commercial building permits for mold remediation in retail, office, or industrial spaces.
- Water damage restoration with structural impact — If mold is the result of plumbing leaks or flooding that requires wall or floor removal, a permit may be needed.
- New construction or additions — Any mold remediation tied to new building work will require standard building permits.
Common Exemptions
There are some situations where a separate permit may not be needed, though a licensed TDLR contractor should still perform the work:
- Small areas (under 25 sq ft) — Minor surface mold on non-structural materials (tile, glass, metal) may not require a permit.
- Routine cleaning — Regular household mold cleaning on hard surfaces without demolition is generally exempt.
- Testing and assessment only — Mold inspection and air quality testing do not typically require a building permit.
- Emergency water extraction — Immediate water removal to prevent mold growth is usually exempt, though follow-up remediation may require permits.

Permit Process
Step 1: Determine Your Scope of Work
Assess how much mold is present and what materials are affected. If the affected area exceeds 25 contiguous square feet or involves structural components, you'll likely need a licensed TDLR mold remediation contractor. Check with the Nacogdoches County permitting office to see if a local building permit is also required for the repair phase.
Step 2: Hire a Licensed Professional
Texas law requires mold remediation contractors to hold a TDLR license. Work with a licensed professional familiar with Martinsville and Nacogdoches County codes. They will know which permits apply and can often pull permits on your behalf as part of their service.
Step 3: Submit Permit Application
If a local building permit is required, the contractor (or homeowner, if doing the work) will submit plans and details to the Nacogdoches County permitting office. This typically includes a description of the remediation scope, the repair plan, and any affected systems (HVAC, plumbing, electrical).
Step 4: Schedule Inspections
Once the permit is approved and work begins, scheduled inspections may be required at key milestones — such as after mold removal is complete but before walls are closed up, and after final repairs are finished. Your contractor should coordinate these inspections with the local building official.
Step 5: Receive Certificate of Completion
After all work passes inspection, a final approval or certificate of completion is issued. This document is important for property records, insurance claims, and future real estate transactions. Keep it with your home or property records.
Compliance Tips
- ✓ Hire a TDLR-licensed mold remediation contractor — Texas law requires it for work over 25 square feet, and licensed pros know the permit process inside and out.
- ✓ Get everything in writing before work starts, including a written contract that outlines the scope, licensing info, and who is responsible for pulling permits.
- ✓ Don't skip the post-remediation inspection — a third-party mold assessment (by a licensed mold assessment consultant, different from the remediator) is recommended to confirm the mold was properly removed.
- ✓ Check with the Nacogdoches County building department early in the process. A quick call can clarify whether your specific project requires a permit, saving you time and potential fines.
- ✓ Keep detailed records of all permits, inspection reports, and certificates of completion. These documents are essential for insurance claims and future property sales.
- ✓ If the mold is from a recent water damage event, document the source of the water and any insurance claim details. This information helps your contractor plan compliant remediation and repair work.
Special Considerations
HOA Rules
If your Martinsville property is part of a homeowners association (HOA), you may need HOA approval before exterior repairs or visible changes begin. Some HOAs have specific requirements about contractor credentials, remediation timelines, and property appearance during and after work. Always check your HOA covenants before starting any project that alters the exterior of your home.
Zoning
Nacogdoches County zoning regulations may affect mold remediation projects, especially for commercial properties or properties in specific zoning districts. Check whether your property is zoned residential, commercial, or agricultural, as this may affect permit requirements, waste disposal rules, and noise or work hour restrictions. Commercial mold remediation often has stricter requirements than residential work.
Historic Properties
Martinsville and Nacogdoches County have several historic properties. If your home or building is located in a designated historic district or is listed on the National Register of Historic Places, additional approvals may be needed. Historic preservation boards often require that mold remediation and repair methods preserve original materials and architectural features. Work with contractors who have experience with historic properties.
