Permit Requirements in Columbus
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 State Health Services (TDSHS). A licensed Mold Assessment Consultant or Mold Remediation Contractor is often required for projects involving more than 25 contiguous square feet of mold growth. Local building permits may also be needed if remediation involves structural repairs, drywall replacement, or HVAC system modifications.
When Permits Are Typically Needed:
- Remediation of significant mold growth (over 25 sq ft)
- Projects requiring removal of drywall, insulation, or structural materials
- Work involving HVAC duct cleaning or system modifications
- Any work tied to water damage restoration that requires building repairs
Always confirm with your local permitting office to determine what applies to your specific situation.
When Permits Are Required
You may need a permit or licensed professional when:
- The affected area exceeds 25 contiguous square feet of mold growth
- Remediation requires cutting into walls, ceilings, or floors
- The project involves replacing drywall, insulation, or framing
- HVAC ductwork needs cleaning, repair, or replacement due to mold
- The work requires electrical or plumbing modifications
- Your homeowner's insurance policy requires licensed remediation
State Licensing Applies When:
- Mold remediation exceeds 25 contiguous square feet (TDSHS rules)
- A licensed Mold Assessment Consultant must assess and develop the remediation protocol
- A licensed Mold Remediation Contractor must perform the work
- Final clearance testing is required to confirm remediation is complete
Common Exemptions
Permits may not be required for:
- Minor spots of mold (less than 25 contiguous square feet) that can be cleaned without structural disturbance
- Routine cleaning of non-porous surfaces with proper mold-cleaning products
- DIY remediation on small areas where no structural components are removed
- Preventative moisture control measures (dehumidifiers, ventilation improvements)
Important Note: Even if a building permit is not needed, TDSHS licensing requirements may still apply for larger projects. Small jobs can quickly grow — if you uncover more mold during cleanup, stop and consult a licensed professional.

Permit Process
Step 1: Determine the Scope of Work
Identify the size of the affected area and whether structural materials (drywall, insulation, framing) need to be removed. This helps determine if state licensing or local permits are triggered.
Step 2: Consult a Licensed Mold Assessment Consultant
For projects over 25 contiguous sq ft, a licensed assessor must inspect the property and develop a remediation protocol. This document outlines the scope and method of remediation work needed.
Step 3: Check Local Permit Requirements
Contact the Columbus or Colorado County permitting office to ask whether a building permit is needed for the structural repairs or replacements involved. Provide the remediation protocol for clarity.
Step 4: Hire a Licensed Mold Remediation Contractor
Once you have the protocol and understand local requirements, hire a TDSHS-licensed Mold Remediation Contractor. Ensure they are familiar with Columbus building codes and will pull any needed permits.
Step 5: Schedule Final Clearance Testing
After remediation is complete, a licensed Mold Assessment Consultant (different from the remediator) performs clearance testing. This verifies the mold has been properly removed before you close up walls or reoccupy the space.
Compliance Tips
- ✓ Always hire a TDSHS-licensed Mold Remediation Contractor for projects exceeding 25 contiguous square feet — unlicensed work can lead to fines and failed insurance claims.
- ✓ Keep all documentation: the assessment report, remediation protocol, permits, contractor invoices, and clearance testing results. These may be needed for insurance or future property sales.
- ✓ Don't skip the clearance testing. It is the only way to confirm the mold was fully remediated and the space is safe to reoccupy.
- ✓ Address the moisture source (leaks, humidity, flooding) before or during remediation. Without fixing the cause, mold will return regardless of how thorough the cleanup is.
- ✓ Ask your contractor upfront if they handle permit applications or if you need to apply separately. A code-compliant pro will know the local process.
- ✓ If you're a landlord or property manager in Columbus, be aware that Texas law requires disclosure of known mold issues to tenants and buyers.
Special Considerations
HOA Rules
If your property is governed by a homeowners' association (HOA), you may need to notify them before starting exterior or structural work. Some HOAs have rules about visible construction materials, dumpster placement, or work hours. Check your HOA covenants and request approval in writing if needed.
Zoning
Zoning regulations in Columbus may affect mold remediation projects that involve structural changes, property expansions, or changes to the building footprint. Commercial properties may face additional zoning requirements. Verify with the Colorado County planning department to ensure your project is zoned appropriately for the planned work.
Historic Properties
Columbus is home to the Columbus Historic District, which includes properties listed on the National Register of Historic Places. If your home is in a designated historic district, any exterior changes — including replacing siding, windows, or roofing as part of mold remediation — may require review and approval from the local historic preservation commission. Always consult with the city before proceeding with exterior structural work.
