Permit Requirements in Dimmitt
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, mold remediation is regulated under TDLR rules (Texas Occupations Code, Chapter 1958). A state license is required for anyone who performs mold remediation for compensation. This means the company or individual you hire must hold a valid TDLR mold remediation license.
When a local building permit may be needed: If mold remediation involves structural repairs, demolition, drywall replacement, or electrical/HVAC work, a standard building permit from the City of Dimmitt or Castro County may also be required alongside the licensed remediation work.
When Permits Are Required
- Licensed remediation required: Any remediation involving more than 25 contiguous square feet of mold contamination typically requires a licensed remediator.
- Structural repairs: If mold damage requires removing or replacing load-bearing walls, roof sheathing, or floor joists, a building permit is often required.
- HVAC system work: Mold in ductwork or HVAC systems may require mechanical permits for cleaning or replacement.
- Demolition: Tearing out significant portions of drywall, insulation, or framing may trigger a demolition or building permit.
- New construction or renovation: If mold remediation is part of a larger renovation project, all applicable building permits for the renovation work still apply.
Common Exemptions
- Minor surface mold: Cleaning mold off non-porous surfaces (like tile or glass) with household cleaners typically does not require a license or permit.
- Property owner performing own work: Property owners may remediate mold on their own property without a license, provided they do not hire others or charge for the work. However, local building permits for any related structural work may still apply.
- Small areas (under 25 sq ft): Very small, contained areas of mold may not require a licensed remediator, though best practices still recommend proper safety precautions.
- Maintenance work: Routine cleaning and minor repairs that don't affect structural elements typically do not require permits.

Permit Process
Step 1: Determine if state licensing or permits are needed
Evaluate the scope of the mold issue. If it covers more than 25 contiguous square feet or involves structural damage, you'll need a TDLR-licensed mold remediation contractor. Check with the City of Dimmitt building department to see if a separate building permit is required for any construction work.
Step 2: Hire a TDLR-licensed mold remediation professional
Verify that any contractor you hire holds a valid TDLR Mold Remediation License. Licensed professionals are trained to follow state-mandated work practices, containment protocols, and disposal requirements. They can also help determine if additional local permits are needed.
Step 3: Submit permit applications for structural work
If the project involves demolition, structural repairs, or electrical/mechanical work, submit the necessary building permit applications to the City of Dimmitt or Castro County. Your contractor or a local design professional can assist with plans and documentation.
Step 4: Plan inspections for remediation and construction
In many cases, a licensed mold assessor (separate from the remediator) will perform post-remediation clearance testing. For structural work, city or county building inspectors will need to sign off on repairs. Coordinate these inspections to ensure all work is compliant.
Step 5: Maintain records and certificates
Keep copies of the TDLR remediation license, any permits pulled, inspection reports, and clearance testing results. These documents are important for property transactions, insurance claims, and future renovations.
Compliance Tips
- ✓ Always verify that your contractor holds a valid TDLR Mold Remediation License before work begins — it's required by Texas state law.
- ✓ If the mold issue is due to a leak or water damage, address the moisture source first or it will return, even after professional remediation.
- ✓ Consider hiring a separate TDLR-licensed Mold Assessor for an independent inspection and clearance testing — this prevents conflicts of interest.
- ✓ Document everything: take before, during, and after photos, and keep all contracts, licenses, permits, and test results for your records.
- ✓ Notify your homeowner's insurance carrier early — some policies cover mold remediation and may have preferred vendor requirements.
- ✓ For structural repairs related to mold damage, don't skip the building permit process — unpermitted work can create issues when selling your home.
Special Considerations
HOA Rules
If your property in Dimmitt is part of a Homeowners Association (HOA), check your HOA's CC&Rs for any specific rules about mold remediation, contractor approval, or restoration work. Some HOAs require pre-approval before work begins or have guidelines for waste disposal and contractor parking.
Zoning
Zoning regulations in Dimmitt and Castro County may affect mold remediation projects, especially for commercial properties or multi-family dwellings. Ensure that waste disposal, equipment staging, and any temporary structures (like containment tents) comply with local zoning and property maintenance codes.
Historic Properties
Dimmitt has historic structures and areas that may be subject to preservation guidelines. If your property is located in or near a historic district, any structural repairs or modifications during mold remediation may require additional review and approval. Always check with local preservation authorities before starting work.
