Permit Requirements in Keller
Know when you need a permit to ensure your project is legal and safe
General Rules
In Keller and unincorporated Tarrant County, permits are typically required when mold remediation involves structural alterations, HVAC system modifications, or significant drywall removal and replacement. Since mold is often a symptom of a larger moisture issue, any repairs addressing the source of water intrusion — such as roof repairs, plumbing work, or foundation fixes — will likely need their own permits.
Texas does not have a statewide mold remediation license, but the Texas Department of Licensing and Regulation (TDLR) oversees mold assessment and remediation companies. Contractors performing mold-related work in Keller must comply with TDLR rules, and local building permits may be needed depending on the scope of work.
When Permits Are Required
Permits may be required in the following situations:
- Structural repairs — If mold damage has compromised framing, drywall, or load-bearing elements, a building permit is often needed for the repair work.
- HVAC system remediation — Mold in ductwork or air handlers may require permits for duct replacement or system modifications.
- Significant drywall removal and replacement — Removing and replacing large sections of drywall (typically over 32 square feet) often triggers permit requirements.
- Plumbing or roof repairs — Fixing the water source that caused the mold growth may require separate plumbing or roofing permits.
- Commercial buildings — Mold remediation in commercial properties almost always requires permits and must follow TDLR licensing rules.
Common Exemptions
Minor mold remediation may not require a permit if:
- The affected area is small (typically under 10 square feet) and can be cleaned without structural changes.
- No walls, ceilings, or flooring need to be removed and replaced.
- The work involves only surface cleaning with no repairs to the building structure.
- The mold issue is superficial and not related to an ongoing moisture problem requiring construction.
Even when a permit isn't required, it's still important to hire professionals who follow industry standard practices (such as IICRC S520 guidelines) for safe mold remediation.

Permit Process
1. Determine if a Permit is Needed
Contact the City of Keller Building Inspections Department or Tarrant County permitting office to discuss your specific project. Provide details about the scope of work, including how much drywall will be removed and whether structural repairs are involved.
2. Hire a Licensed Professional
For work requiring permits, you'll need a licensed contractor. In Texas, mold remediation companies must be licensed by TDLR if the work area exceeds 25 contiguous square feet. Confirm your contractor holds a valid TDLR mold remediation license and any required local business permits.
3. Submit Permit Application
Your contractor or the homeowner can submit the permit application to the appropriate building department. Applications typically require a detailed scope of work, material specifications, and sometimes a mold remediation plan from a licensed mold assessment consultant.
4. Schedule Inspections
Once work begins, inspections may be required at key stages — such as after mold removal but before new drywall is installed. This ensures the area is properly remediated and the moisture source has been addressed. A final inspection may also be needed before the permit is closed.
5. Obtain Certificate of Completion
After passing all required inspections and completing the work, a permit sign-off or certificate of completion is issued. This documentation is important for insurance purposes and when selling your home.
Compliance Tips
- ✓ Always verify your mold remediation contractor holds a valid TDLR license in Texas — this is required for work exceeding 25 contiguous square feet.
- ✓ Document everything: take photos of the mold before work begins, keep all contracts and permits, and save inspection reports for your records and insurance claims.
- ✓ Address the moisture source first — mold remediation without fixing the underlying leak or humidity issue is a temporary fix and may lead to repeat problems.
- ✓ Use an independent mold assessment consultant (separate from the remediation company) for larger jobs to ensure unbiased testing and verification of complete remediation.
- ✓ Check with your homeowners insurance policy — some policies cover mold remediation from covered water damage, but may require permits and licensed contractors for claim approval.
- ✓ Don't skip the final inspection even for small jobs — a signed-off permit provides proof that the work was done correctly, which matters when selling your home.
Special Considerations
HOA Rules
If your Keller home is part of a homeowners association, check your HOA's CC&Rs before starting mold remediation. Some HOAs have specific rules about contractor access, dumpster placement, and exterior work. Additionally, if mold damage resulted from a common area issue (such as shared roofing or plumbing), the HOA may be responsible for repairs. Always notify your HOA in writing before significant remediation work begins.
Zoning
Keller's zoning regulations typically don't directly affect interior mold remediation, but they may apply if the work involves changes to the building's footprint, exterior modifications, or changes in use. For commercial properties, zoning rules may impact how mold remediation waste is handled and disposed of. Always confirm with the city that your project is consistent with current zoning requirements.
Historic Properties
Keller has designated historic properties and neighborhoods. If your home is located in a historic district or is a designated historic structure, any exterior repairs or structural changes related to mold remediation may require approval from the historic preservation board. Work must preserve the historic character of the building. Check with the City of Keller's planning department before beginning any exterior modifications.
