Permit Requirements in Tyler
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, anyone performing mold remediation for compensation must be licensed by the Texas Department of Licensing and Regulation (TDLR) when the work involves more than 25 contiguous square feet of mold growth. This applies to both the mold assessment company (testing/inspection) and the remediation company (removal/cleanup).
State licensing covers:
- Mold remediation contractors
- Mold assessment technicians and companies
- Work supervisors overseeing remediation projects
Always verify that any contractor you hire holds a valid TDLR license for the specific scope of work needed.
When Permits Are Required
A licensed mold remediation professional is typically required when:
- Visible mold covers more than 25 contiguous square feet (about a 5' x 5' area)
- The mold is caused by sewage backup or contaminated water (Category 3 water damage)
- HVAC systems are contaminated with mold
- The property is being sold or leased and mold is discovered during inspection
- Mold is found in rental properties where landlord remediation is needed
- The mold issue stems from structural moisture problems requiring demolition
Local building permits may also be needed when remediation involves:
- Removing and replacing drywall, insulation, or structural materials
- Modifying HVAC systems or ductwork
- Making structural repairs after mold removal
Common Exemptions
A TDLR license may NOT be required for:
- Small, isolated patches of mold (less than 25 contiguous square feet) that you clean yourself using proper safety precautions
- Property owners performing remediation on their own primary residence (though safety precautions are still strongly advised)
- Routine cleaning of non-porous surfaces with minor mold growth
- Maintenance staff performing minor spot cleaning as part of regular building upkeep
Important: Even if a state license isn't required, you may still need local building permits if the remediation involves demolition, structural work, or electrical modifications. Always check with Smith County or City of Tyler permitting offices to be sure.

Permit Process
Step 1: Determine Scope of Work
Assess the size and severity of the mold problem. If the affected area exceeds 25 contiguous square feet, state law requires a licensed mold remediation company. Have a licensed mold assessment company inspect and test first — they can provide a clear scope of work and determine if local permits are needed for any repairs.
Step 2: Verify Contractor Licenses
Before any work begins, confirm that your mold remediation contractor holds a valid TDLR Mold Remediation Contractor license. You can verify this through the TDLR license lookup tool. Never hire an unlicensed contractor for large-scale remediation — it's against state law and could create liability issues down the road.
Step 3: Pull Local Permits if Required
If the remediation requires removing structural materials, replacing drywall, modifying HVAC, or making electrical changes, you may need a building permit from the City of Tyler or Smith County. The contractor should handle this, but it's wise to confirm. Permits ensure the repairs after mold removal meet local building codes.
Step 4: Containment and Remediation
A licensed remediation company will set up proper containment (negative air pressure, plastic barriers, HEPA filtration) to prevent mold spores from spreading to other areas. They'll follow TDLR-approved work practices for removal, cleaning, and disposal of mold-contaminated materials.
Step 5: Post-Remediation Clearance Testing
After remediation is complete, a separate licensed mold assessment company (not the remediator) should perform clearance testing to confirm the mold has been properly removed. This is a best practice and often required for documentation, especially in real estate transactions or insurance claims.
Step 6: Final Inspections and Repairs
Once clearance is obtained, any structural repairs, drywall replacement, or HVAC work can proceed. If local permits were pulled, schedule final inspections with the city or county to sign off on the work. Your contractor should coordinate this step.
Compliance Tips
- ✓ Always hire a TDLR-licensed remediator — Texas law requires it for any remediation over 25 square feet. Unlicensed work can result in fines and liability.
- ✓ Keep remediation separate from assessment — The company testing for mold should be different from the company removing it. This avoids conflicts of interest and ensures unbiased clearance testing.
- ✓ Document everything — Save all contracts, license verifications, containment records, and clearance test results. This is critical for insurance claims and future property disclosures.
- ✓ Don't skip the building permit — Even if TDLR licensing is handled, structural repairs after mold removal often require a separate building permit from the City of Tyler or Smith County.
Special Considerations
HOA Rules
If your Tyler home is in a homeowners association (HOA)-governed community, check your HOA bylaws regarding mold remediation. Some HOAs require prior approval before any exterior or structural work begins, including the removal of siding or roofing materials. You may also need to provide documentation of licensed remediation and clearance testing to satisfy HOA property maintenance standards.
Zoning
Zoning regulations in Tyler typically don't affect interior mold remediation directly. However, if the remediation involves changes to the building's footprint, new construction for ventilation, or modifications that affect setbacks or occupancy use, zoning approvals may be needed. This is most relevant for commercial properties or multi-unit residential buildings. Always verify with the Tyler Planning and Zoning Department if you're making structural changes.
Historic Properties
Properties located in Tyler's historic districts (such as the Brick Streets neighborhood or the Southside Historic District) may have additional restrictions. Any structural repairs or material replacements following mold remediation must often match the original construction in appearance and materials. You may need approval from the Tyler Historic Preservation Board before making visible alterations. Work with contractors familiar with historic property requirements.
