Permit Requirements in Catarina
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, mold remediation is regulated at the state level by the Texas Department of Licensing and Regulation (TDLR). While building permits for mold work are not always required for minor surface cleanup, permits are often needed when remediation involves structural repairs, drywall replacement, HVAC modifications, or significant demolition.
Catarina and Dimmit County generally follow standard building codes that require permits when mold remediation involves altering the structure of a building, replacing large sections of affected materials, or making changes to mechanical systems.
When Permits Are Required
Permits may be required in Catarina when mold remediation involves:
- Structural repairs or demolition of walls, ceilings, or flooring affected by mold
- HVAC system modifications that involve ductwork replacement or equipment changes
- Electrical or plumbing work associated with addressing moisture sources
- Significant drywall removal and replacement beyond minor patching
- Commercial properties where remediation may require additional health and safety permits
Additionally, any mold remediation project performed by a contractor must comply with TDLR licensing requirements for mold assessment and remediation companies, regardless of whether a building permit is needed.
Common Exemptions
Minor mold cleanup may not require a building permit if:
- The affected area is small (typically under 10 square feet)
- No structural changes, wall removal, or demolition is involved
- The work is purely cosmetic surface cleaning (non-porous materials)
- No electrical, plumbing, or HVAC work is needed
Homeowners performing their own small-scale cleanup on their primary residence may not need a permit, but it is always wise to verify with local authorities. Even when a permit isn't required, work should still follow proper mold remediation safety practices.

Permit Process
Step 1: Determine If You Need a Permit
Contact the Dimmit County permitting office or the applicable local authority to discuss your specific mold remediation project. Provide details about the scope of work, affected square footage, and any structural repairs planned. They can tell you whether a building permit or other approvals are required.
Step 2: Hire a TDLR-Licensed Mold Remediation Contractor
Texas law requires mold remediation companies to be licensed by the TDLR. Ensure the contractor you hire holds a valid TDLR Mold Remediation license. Licensed professionals are better equipped to handle the permit process and ensure all work meets applicable codes and standards.
Step 3: Submit Required Documentation
If a permit is needed, your contractor will typically handle submitting the application, which may include a scope of work, affected area diagrams, remediation protocols, and contractor license information. Some projects may require a mold assessment report from a licensed mold assessment consultant.
Step 4: Schedule Inspections
Once work begins, inspections may be required at key milestones — such as after containment setup, before closing walls, and after final clearance testing. A licensed mold assessment consultant typically performs post-remediation verification (clearance testing) to confirm the area is safe.
Step 5: Obtain Final Approval
After all work is complete and any required inspections pass, you will receive final approval. Keep all documentation, including permits, inspection reports, and clearance testing results, for your records — they may be needed for future real estate transactions or insurance claims.
Compliance Tips
- ✓ Always verify that your mold remediation contractor holds a valid TDLR license — this is a Texas state requirement, not optional.
- ✓ Get a pre-remediation mold assessment from a licensed mold assessment consultant before work begins to document the scope and conditions.
- ✓ Keep detailed records of all permits, inspection reports, contractor licenses, and post-remediation clearance testing results.
- ✓ Don't skip the permit process even for small jobs — unpermitted work can cause issues when selling your home or filing insurance claims.
- ✓ Address the moisture source (leaky pipes, poor drainage, humidity issues) to prevent mold from returning after remediation.
Special Considerations
HOA Rules
If your Catarina property is part of a homeowners association (HOA), check your CC&Rs before starting mold remediation. Some HOAs have specific requirements regarding contractor approvals, work hours, exterior changes related to moisture mitigation, and property appearance during and after remediation. HOA approval is typically separate from local building permits.
Zoning
Zoning regulations in Dimmit County may affect mold remediation projects, particularly for properties in flood-prone areas or those requiring significant exterior drainage and grading work to address moisture sources. Verify setback requirements and any special zoning rules if your remediation involves structural changes or additions to the building envelope.
Historic Properties
Catarina and Dimmit County may have properties that fall under historic preservation guidelines. If your property is designated or located in a historic district, any structural changes made during mold remediation — including wall repairs, material replacements, or exterior modifications — may require additional review. Contact local preservation authorities early in the process.
