Mold Remediation Permits in Lorena
If you've discovered mold in your Lorena home, you're likely wondering what rules apply before work begins. Mold remediation in Texas is regulated by the Texas Department of Licensing and Regulation (TDLR), and while a traditional building permit may not always be required, compliance with state licensing rules is often mandatory. This guide covers when you need a licensed mold remediation contractor, how the process works, and what to watch out for. Always verify requirements with local and state authorities before starting any mold removal project.

Permit Requirements in Lorena
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 the City of Lorena may not issue a specific 'mold permit' like a building permit, any mold remediation involving more than 25 contiguous square feet of mold growth typically requires a state-licensed mold remediation contractor. The company performing the work must hold a TDLR Mold Remediation License, and the work must be overseen by a licensed Mold Remediation Contractor.
Additionally, a separate Mold Assessment Consultant (also TDLR-licensed) must perform the initial inspection and final clearance testing. The assessor and remediator cannot be the same company to avoid conflicts of interest.
When Permits Are Required
A licensed mold remediation contractor is typically required in these situations:
- Visible mold growth covering more than 25 contiguous square feet in a residential or commercial building
- Mold resulting from significant water damage, flooding, or sewage backup
- Mold in HVAC systems affecting multiple rooms or zones
- Rental properties where landlords are legally obligated to remediate properly
- Properties being sold where mold is discovered during a home inspection
- Commercial buildings where occupant health and liability are concerns
- Post-construction moisture issues leading to widespread mold growth
Common Exemptions
Licensed remediation may not be required in these situations:
- Small, isolated patches of mold (less than 25 contiguous square feet) that can be safely cleaned with household products
- Surface mold on hard, non-porous materials like tile or glass that can be wiped clean
- Minor mold on window sills or bathroom surfaces caused by routine humidity
- Property owners performing cleanup on their own primary residence, provided no structural damage exists
Important: Even when exempt, proper safety precautions (gloves, N95 masks, ventilation) should always be used. If the mold is suspected to be toxic (Stachybotrys) or if anyone in the home has respiratory issues, professional remediation is strongly recommended regardless of square footage.

Permit Process
Step 1: Mold Assessment (Inspection)
A TDLR-licensed Mold Assessment Consultant inspects the property to identify the type and extent of mold growth. They will take air and surface samples, identify the moisture source, and produce a remediation protocol (scope of work). This assessment must be performed before any remediation work begins.
Step 2: Hire a Licensed Remediation Contractor
Using the assessment report, hire a TDLR-licensed Mold Remediation Contractor. Make sure their license is current through the TDLR website. The contractor will set up containment barriers, use negative air pressure, and follow the protocol established by the assessor.
Step 3: Remediation Work
The licensed contractor performs the mold removal following strict TDLR guidelines. This includes HEPA vacuuming, antimicrobial application, removal of contaminated materials (drywall, insulation), and proper disposal in sealed bags. Work areas are contained to prevent cross-contamination.
Step 4: Post-Remediation Clearance Testing
After remediation, the original Mold Assessment Consultant (or another independent licensed assessor) returns to perform clearance testing. Air samples are compared to baseline outdoor samples. Only when results show mold levels are normal is the space declared safe for re-occupancy.
Step 5: Documentation & Final Reports
The assessor provides a final clearance report. The remediation contractor provides a project summary. Keep all documentation — insurance companies, future home buyers, and property records may require proof of proper mold remediation by licensed professionals.
Compliance Tips
- ✓ Always hire a TDLR-licensed Mold Remediation Contractor — never accept an unlicensed contractor offering mold removal, even if the price is lower.
- ✓ Ensure the Mold Assessment and Mold Remediation are done by separate, unrelated companies. This is a TDLR requirement to prevent conflicts of interest.
- ✓ Get everything in writing: the assessment report, remediation protocol, contract, and final clearance test results. This protects you legally and for insurance purposes.
- ✓ Ask for proof of insurance (general liability and workers' compensation) from any contractor before work begins. This protects you if something goes wrong.
- ✓ Don't paint over or seal mold without removing the moisture source first. Mold will continue to grow beneath the surface and cause greater damage over time.
- ✓ If small mold patches are on your personal property (under 25 sq ft), use proper safety gear and EPA-recommended cleaning methods. When in doubt, call a licensed professional.
Special Considerations
HOA Rules
If your Lorena home is part of a homeowners association (HOA), check your HOA covenants for any rules regarding exterior work, waste disposal, or property appearance during remediation. Some HOAs may require advance notice for dumpster placement or containment equipment visible from the street. HOA rules cannot override state TDLR licensing requirements, but they may add notification or approval steps.
Zoning
Mold remediation in commercial or multi-family properties may be subject to local zoning and business occupancy regulations in Lorena and McLennan County. If the remediation involves significant demolition, structural changes, or alterations to building systems (HVAC, plumbing), separate building permits may be required. Check with the City of Lorena building department for any local permit requirements tied to construction-related remediation work.
Historic Properties
Lorena has historic properties and structures that may fall under local preservation guidelines. If your home is in or near a historic district, consult with the City of Lorena planning department before any remediation work. Exterior modifications, window replacements, or structural changes tied to mold removal may require additional approvals. Always use licensed professionals familiar with historic property compliance.
