Permit Requirements in Blum
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, mold remediation contractors must hold a TDLR-issued license for any remediation project exceeding 25 contiguous square feet of mold. This applies across all cities, including Blum. For smaller jobs under that threshold, a license may not be required, but it's still wise to hire trained professionals.
Local building permits from Hill County or the City of Blum may be needed if the remediation involves structural repairs, drywall replacement, electrical work, or HVAC modifications. Always verify with local authorities before starting work.
When Permits Are Required
A TDLR-licensed mold remediation professional is often required when:
- The affected area exceeds 25 contiguous square feet
- The mold is a result of sewage backup or flooding
- The remediation involves removing and replacing drywall, insulation, or flooring
- HVAC systems are contaminated and need cleaning or replacement
- Structural repairs are needed after mold removal
Additionally, a local building permit may be required if the project involves:
- Altering load-bearing walls or framing
- New electrical wiring or outlets
- Modifications to plumbing systems
- Significant structural reconstruction after mold removal
Common Exemptions
Minor mold remediation work may not require a TDLR-licensed contractor or local permit if:
- The area of mold is less than 25 contiguous square feet (roughly a 5x5 ft section)
- The work is purely cosmetic surface cleaning (no material removal)
- The issue is minor condensation or surface mildew on non-porous surfaces
However, even for small jobs, proper safety precautions (like using PPE and containment) are strongly recommended. When in doubt, consult with a licensed professional to assess the situation.

Permit Process
Step 1: Assess the Scope of Mold Growth
Have the area professionally inspected to determine the extent of mold contamination. This helps establish whether the job exceeds 25 square feet and whether a TDLR-licensed contractor is required. A licensed inspector can also identify underlying moisture issues.
Step 2: Determine Permit and Licensing Needs
Based on the assessment, check whether TDLR licensing is required and whether local building permits in Blum or Hill County are needed. Contact the Hill County Building Department or the City of Blum municipal office to ask about permit requirements for any planned structural or mechanical work.
Step 3: Hire a Licensed Professional
If the job requires a TDLR license, hire a state-licensed mold remediation company. Verify their license status through the TDLR website. For smaller jobs, still consider working with contractors familiar with local building codes to ensure all work is done properly.
Step 4: Submit Permit Applications (If Required)
If local permits are needed (for structural repairs, electrical, or HVAC work), submit the required applications to Hill County or the City of Blum. Provide detailed scope of work and any contractor licensing documentation. Wait for approval before beginning work.
Step 5: Schedule Inspections
After the mold remediation and any associated repairs are completed, schedule required inspections with local authorities. This may include a final building inspection to verify that structural, electrical, or mechanical work meets code. Keep all documentation for your records.
Compliance Tips
- ✓ Always verify your mold remediation contractor's TDLR license status through the Texas Department of Licensing and Regulation website before hiring.
- ✓ Keep detailed records of all permits, inspection reports, and contractor licenses — they may be needed for insurance claims or future property sales.
- ✓ Do not attempt to bypass licensing requirements by dividing a large mold problem into smaller sections — TDLR regulations consider the total contiguous affected area.
- ✓ Address the source of moisture (leaks, humidity, flooding) before or during remediation to prevent mold from returning and potential code violations.
- ✓ Check with Hill County or the City of Blum well before starting work if your project involves any structural repairs, electrical work, or HVAC changes.
- ✓ Hire only licensed and insured professionals — unlicensed mold remediation work can lead to fines, insurance denial, and potential health hazards.
Special Considerations
HOA Rules
If your Blum home is part of a homeowners association (HOA), check your HOA's governing documents before starting mold remediation. Some HOAs require prior notification or approval for exterior modifications, dumpster placement, or construction activity. You may also need to follow specific remediation protocols if mold affects common areas or neighboring units.
Zoning
Zoning regulations in Blum and Hill County typically don't restrict interior mold remediation, but they may apply if the project involves exterior work, such as adding ventilation systems, changing the building footprint, or disposing of large amounts of debris. Always check local zoning rules before beginning work that alters the exterior of your property.
Historic Properties
Blum and Hill County have historic homes and properties. If your property is located in or near a designated historic district, additional approvals may be required before any structural changes are made. Contact the Hill County Historical Commission to determine if your property has historic designations that could affect mold remediation plans.
