Permit Requirements in Corsicana
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, mold remediation is regulated by state-level licensing requirements rather than traditional building permits in most cases. Any mold remediation involving more than 10 square feet of visible mold growth typically requires the work to be performed by a licensed mold assessor and a licensed mold remediation contractor.
Corsicana follows Texas state regulations, meaning remediation projects that involve removing, cleaning, or treating mold-contaminated materials may require licensed professionals. The key distinction is that permits are often tied to the scope of work — minor spot remediation may not trigger requirements, while larger or HVAC-related remediation usually will.
When Permits Are Required
A licensed mold remediation contractor is generally required when:
- The total surface area of mold growth exceeds 10 contiguous square feet
- Mold is present in HVAC systems or ductwork
- The contamination is in common areas of multi-unit buildings
- The mold resulted from sewage backup or floodwater (Category 2 or 3 water damage)
- The remediation involves removing and replacing drywall, insulation, or other building materials
- The property is being renovated and mold is discovered during construction
Additionally, if the remediation is part of a larger renovation project, a standard building permit from the City of Corsicana may be required for demolition, structural repairs, or new construction.
Common Exemptions
Permit and licensing requirements may not apply in certain situations, including:
- Small, isolated spots of mold (less than 10 square feet) that can be cleaned with household products
- Surface mold on non-porous materials that can be wiped clean without disturbing building materials
- Routine cleaning and maintenance by property owners on their own single-family residence
- Minor condensation-related mold in bathrooms or kitchens that is cleaned promptly
However, always verify with local authorities — what starts as a small job can quickly expand once hidden moisture damage is discovered.

Permit Process
Assess the Scope
Determine the extent of mold contamination. If visible mold covers more than roughly 10 square feet, or if you suspect hidden growth behind walls or in HVAC systems, you likely need a licensed mold assessor to evaluate the property before any remediation begins.
Hire Licensed Professionals
Texas law requires separate licensing for mold assessors and mold remediation contractors. Ensure the company you hire holds the appropriate TDLR-issued license. A reputable contractor should be able to provide their license number and proof of insurance.
Obtain Required Permits
If the remediation involves structural changes, demolition, or new construction, check with the City of Corsicana's building department to determine if a standard building or demolition permit is needed. Your contractor should handle this coordination.
Remediation and Clearance Testing
After remediation is complete, a licensed mold assessor (who is independent from the remediation company) should perform post-remediation verification testing to confirm the mold has been properly removed and the area is safe.
Documentation and Record Keeping
Keep all reports, licenses, permits, and clearance testing results on file. These documents are important for insurance claims, future property transactions, and demonstrating code compliance.
Compliance Tips
- ✓ Always verify that your mold remediation contractor holds a valid Texas mold remediation license before signing any contract.
- ✓ Get a written scope of work and remediation protocol from a licensed mold assessor before work begins — never let the remediation company write their own protocol.
- ✓ Request proof of insurance including general liability and workers' compensation from any contractor you hire.
- ✓ Keep a paper trail: retain all contracts, permits, inspection reports, and clearance testing results for at least 3 years.
- ✓ If mold is discovered during a renovation, pause work and bring in a licensed assessor — unlicensed disturbance can spread spores throughout the property.
- ✓ Beware of contractors who claim permits are never needed — reputable pros will help you navigate the requirements, not avoid them.
Special Considerations
HOA Rules
If your Corsicana home is part of a homeowners association (HOA), check your HOA's governing documents. Some HOAs have specific rules about mold remediation, including required notification before work begins, approved contractor lists, or restrictions on exterior equipment like containment units. Failing to notify your HOA could result in fines or stop-work orders.
Zoning
Corsicana's zoning ordinances may affect mold remediation in commercial or industrial properties. Depending on the zone, outdoor containment, waste disposal, or air scrubber exhaust may be subject to additional regulations. Check with the City of Corsicana planning department to ensure your remediation plan aligns with local zoning requirements.
Historic Properties
Corsicana has several historic districts and properties listed on the National Register of Historic Places. If your property is in a historic district, any remediation involving structural changes or material removal may require additional review from the local historic preservation board. Work must minimize damage to historic building materials where possible.
