Permit Requirements in Marfa
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). While minor cleanup of small areas (under 25 square feet) may not require formal involvement, larger remediation projects often need licensed professionals. Local building permits may also be required if the mold remediation involves structural repairs, drywall replacement, or addressing moisture intrusion that affects the building envelope.
When a permit is often required:
- Remediation covering more than 25 contiguous square feet of mold
- Projects requiring removal of drywall, insulation, or structural materials
- Work that involves HVAC system cleaning or duct replacement
- Remediation linked to water damage repair that needs building permits
When Permits Are Required
Specific situations that typically require permits in Marfa:
- Mold remediation following major water damage or flooding that requires structural drying and reconstruction
- Commercial or multi-family residential mold remediation projects
- Mold removal that requires cutting into walls, ceilings, or floors for access
- Work that modifies the building's mechanical systems (HVAC, ventilation)
- Any remediation tied to renovations or repairs that independently need building permits in Presidio County
Licensed mold assessors and remediators must follow TDLR rules, including the Mold Assessment and Remediation Rules (MARR).
Common Exemptions
Situations where a permit may NOT be needed:
- Small, isolated areas of mold (less than 10-25 square feet) that can be cleaned with household products
- Non-structural surface cleaning by property owners on their own residence
- Minor moisture control work that doesn't involve structural changes
Important: Even if a building permit isn't required, Texas state law may still require that remediation work be performed by TDLR-licensed professionals if it exceeds certain thresholds. Always check with local authorities before proceeding.

Permit Process
Step 1: Determine Scope of Work
Assess the size and severity of the mold problem. If it covers more than 25 square feet or involves structural materials, you'll likely need a licensed professional. Contact the Marfa Building Department or Presidio County to ask whether a permit is needed for your specific project.
Step 2: Hire Licensed Professionals
Texas requires mold remediation to be performed by TDLR-licensed companies for larger jobs. Look for contractors who hold a valid TDLR Mold Remediation License. They will understand both state regulations and local Marfa building requirements.
Step 3: Submit Permit Application
If a building permit is required, your contractor will typically handle the application. This often includes a scope of work, remediation plan, and any related repair drawings. Fees may apply and processing times vary, so plan ahead.
Step 4: Remediation and Inspection
Once permitted, the licensed team proceeds with containment, removal, and cleanup. After the work is complete, a licensed mold assessor (separate from the remediator) performs a post-remediation verification to confirm the area is safe.
Step 5: Final Approval and Documentation
Keep all paperwork — the permit, remediation reports, and inspection certificates — for your records. These documents may be needed for insurance claims, real estate transactions, or future property disclosures.
Compliance Tips
- ✓ Always verify that your mold remediation contractor holds a valid TDLR license before signing any agreement.
- ✓ For larger jobs, Texas law requires a separate licensed mold assessor — the remediator cannot assess their own work.
- ✓ Document everything: photos of the mold, the remediation process, and final clearance reports for insurance purposes.
- ✓ Don't skip the permit step — unpermitted mold work can create issues when selling your home or filing insurance claims.
- ✓ If your mold problem stems from a leak or water intrusion, address the source first or it will come back — even with a permit.
Special Considerations
HOA Rules
If your Marfa property is part of a homeowners association (HOA), check your CC&Rs before starting mold remediation. Some HOAs require advance notice or approval for exterior work, dumpster placement, or structural changes. Always coordinate with your HOA board to avoid fines or delays.
Zoning
Presidio County and Marfa zoning regulations may affect mold remediation projects, especially for commercial properties. Outdoor work like containment setup, waste disposal, or equipment staging may be subject to zoning restrictions. Check with the Marfa Planning Department to ensure compliance.
Historic Properties
Marfa is home to many historic buildings, particularly in the downtown area. If your property is located in a historic district or is a designated historic structure, any work that alters the building's appearance or structure — even mold-related repairs — may need approval from the Marfa Historic Preservation Commission. Use licensed contractors familiar with historic property requirements.
