Mold Remediation Permits in Lexington, TX
If you're dealing with mold in your Lexington home, you're likely wondering whether a permit is required before work begins. The answer depends on the scope of the work, the extent of the mold, and whether structural changes are needed. In Texas, mold remediation itself doesn't always require a traditional building permit, but there are important state regulations and local rules in Lee County that may apply — especially if removal involves cutting into walls, replacing drywall, or addressing underlying plumbing or HVAC issues. This guide walks you through what's typically required so you can plan your project with confidence and avoid compliance headaches down the road.

Permit Requirements in Lexington
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, mold remediation professionals must be licensed by the Texas Department of Licensing and Regulation (TDLR) when the affected area exceeds 25 contiguous square feet. While this is a licensing requirement rather than a building permit per se, many remediation projects in Lexington also trigger local building permits when they involve structural repairs, drywall replacement, or mechanical system modifications.
Lexington and Lee County typically follow the International Residential Code (IRC), meaning any repair that removes or replaces structural components, alters load-bearing walls, or changes the building envelope may require a permit from the local building authority.
When Permits Are Required
A permit may be required in Lexington when mold remediation involves:
- Structural repairs — replacing rotted studs, joists, or subflooring due to mold damage
- Significant drywall removal and replacement — replacing large sections of wallboard that affect fire-rated assemblies
- HVAC modifications — cleaning or replacing ductwork, especially if new duct runs are installed
- Plumbing repairs — fixing the water source that caused the mold, which may require a plumbing permit
- Electrical work — moving or replacing wiring damaged by moisture
- New construction or additions — rebuilding areas that were removed for remediation
For smaller-scale mold removal (less than 25 contiguous square feet) with no structural changes, a building permit is typically not required, but the work should still follow industry best practices.
Common Exemptions
Minor mold remediation work often does not require a permit. Common exemptions may include:
- Small affected areas — less than 25 contiguous square feet of mold growth
- Cosmetic repairs — painting over minor surface mold with mold-resistant paint (not recommended without addressing the source)
- Cleaning only — using store-bought mold cleaners on non-porous surfaces
- Routine maintenance — fixing a small leak with no drywall or structural damage
Even when a permit isn't required, it's still wise to hire a TDLR-licensed mold remediation professional to ensure the work is done safely and thoroughly.

Permit Process
Determine the Scope of Work
Start by assessing the size of the affected area and whether structural repairs will be needed. If the mold covers more than 25 contiguous square feet, Texas law requires a licensed mold remediation company. If structural damage is involved, you'll likely need a building permit too.
Contact Lexington's Building Department
Check with the City of Lexington or Lee County building authority to ask whether your specific project requires a permit. Be prepared to describe the extent of the remediation and any planned repairs. They can tell you exactly which permits apply to your situation.
Hire a Licensed & Insured Professional
Work with a TDLR-licensed mold remediation contractor who understands local code requirements. A qualified professional will know whether your project needs permits and can often pull them on your behalf as part of their service.
Submit Plans and Apply for Permits
If a permit is needed, you or your contractor will submit an application to the local building department. This may require a scope of work description, material specifications, and sometimes a mold assessment report from a licensed mold assessor.
Schedule Inspections
After remediation and repairs are complete, the local building inspector may need to sign off on the work — especially if structural, electrical, or plumbing work was performed. Clearance testing by a licensed mold assessor may also be recommended to confirm the mold has been properly removed.
Compliance Tips
- ✓ Verify TDLR licensing — Always confirm your mold remediation contractor holds a valid Texas mold remediation license for any project over 25 contiguous square feet. You can check license status on the TDLR website.
- ✓ Don't skip the source fix — Permits aren't just about the removal. If the underlying leak or moisture issue requires plumbing or structural work, get those permits too. Unpermitted repairs can cause issues when selling your home.
- ✓ Get it in writing — Have your contractor provide a detailed scope of work and any permit documentation before work begins. This protects both you and the contractor and ensures everyone is on the same page.
- ✓ Keep records for resale — Home sellers in Texas are required to disclose known mold issues. Having proof of licensed, permitted remediation can be a strong selling point and may prevent legal disputes down the line.
- ✓ Separate assessor from remediator — Texas law encourages using different companies for mold assessment and remediation to avoid conflicts of interest. A licensed mold assessor can provide an independent clearance report after the work is done.
- ✓ Check for asbestos first — In older Lexington homes (pre-1980s), mold remediation that disturbs building materials may also disturb asbestos. Have suspect materials tested before demolition begins to avoid creating a more serious hazard.
Special Considerations
HOA Rules
If your Lexington home is within a homeowners association (HOA), check your HOA covenants before starting mold remediation work. Some HOAs have rules about exterior appearance changes, construction debris removal, and work hours for contractors. Major repairs that alter the exterior of your home may require HOA approval in addition to any city permits.
Zoning
Zoning regulations in Lexington and Lee County generally don't restrict interior mold remediation directly. However, if the remediation involves expanding the footprint of your home, adding new structures (like a porch or enclosure), or changing the use of a space, you'll need to verify that the project complies with local zoning ordinances. Always check setback requirements and lot coverage limits if rebuilding is part of your plan.
Historic Properties
Lexington has several historic properties, particularly in older parts of town. If your home is located in a recognized historic district or is designated as a historic structure, any exterior alterations or major interior renovations may require review by a historic preservation commission. Mold remediation in historic homes often requires special care to preserve original materials while addressing moisture issues.
