Permit Requirements in Justin
Know when you need a permit to ensure your project is legal and safe
General Rules
In Justin, TX, permits for mold remediation are generally governed by the Texas Mold Assessment and Remediation Rules (TMARR) through the Texas Department of Licensing and Regulation (TDLR). A permit or license from TDLR is often required for anyone performing mold remediation for compensation, depending on the scope of work.
For structural repairs tied to mold removal — such as cutting out drywall, replacing framing, or modifying HVAC systems — a standard building permit from the City of Justin or Denton County may also be necessary. Always verify whether your specific project crosses the threshold into work that requires city-level approval.
When Permits Are Required
Permits and licenses are typically required when:
- The area of mold growth exceeds 25 contiguous square feet (this often triggers TDLR licensing requirements for the contractor)
- Structural repairs are needed, such as replacing drywall, insulation, subflooring, or load-bearing elements
- The work involves modifying electrical, plumbing, or HVAC systems affected by mold
- The property is being renovated as part of a larger construction or remodeling project where mold is discovered
- A licensed mold assessment consultant (not the remediator) is required by TDLR rules for larger projects
Common Exemptions
Minor mold remediation work may not require a permit if:
- The affected area is small (typically under 10-25 square feet) and involves only surface cleaning with no structural repairs
- The homeowner is performing the work themselves on their own residence (though caution is strongly advised)
- The work involves only cleaning non-porous surfaces without demolition or replacement of building materials
However, even when a permit isn't required, following industry-standard containment and safety practices is still strongly recommended. When in doubt, consult with a licensed professional.

Permit Process
Determine if a Permit Is Needed
Start by assessing the scope of your mold issue. If the affected area is larger than 25 square feet or involves structural repairs, you'll likely need a licensed remediator and possibly a building permit. Contact the City of Justin or Denton County building department to confirm requirements for your specific situation.
Hire a Licensed Mold Remediation Contractor
For covered projects, TDLR requires that remediation be performed by a company holding a Mold Remediation License. Look for professionals who are TDLR-licensed and familiar with local permitting requirements in Denton County. They can often handle the permit application process on your behalf.
Submit Permit Application and Supporting Documents
If a building permit is required, you or your contractor will need to submit an application along with any necessary documentation, such as a scope of work, containment plan, and mold assessment report. Fees may apply based on the project's value and scope.
Schedule Inspections
Once the permit is approved and work begins, inspections may be required at key stages — for example, after containment is set up, before closing up walls, and after final clearance testing. A licensed mold assessment consultant typically performs the final clearance testing to verify the remediation was successful.
Receive Final Approval
After all inspections pass and clearance is confirmed, the permit is closed out. Keep copies of all documentation, including the mold assessment report, remediation records, and final clearance letter. These may be needed for future property disclosures or real estate transactions.
Compliance Tips
- ✓ Always verify that your mold remediation contractor holds a valid TDLR Mold Remediation License for projects exceeding 25 square feet.
- ✓ Get a mold assessment from a licensed Mold Assessment Consultant before work begins — this creates an official record and helps guide the remediation plan.
- ✓ Keep all paperwork: assessment reports, remediation protocols, permits, inspection records, and final clearance letters. These documents are invaluable for insurance claims and future home sales.
- ✓ Don't mix up mold assessment and mold remediation — Texas law requires these to be performed by separate licensed entities to avoid conflicts of interest.
- ✓ If you're a homeowner doing small-scale cleanup yourself, use proper PPE (N95 respirator, gloves, eye protection) and ensure the area is well-ventilated and contained.
- ✓ Contact the City of Justin or Denton County building department directly for questions about building permits tied to structural repairs from mold damage.
Special Considerations
HOA Rules
If your home in Justin is part of a homeowners association (HOA), check your HOA's guidelines before starting any mold remediation work. Some HOAs have rules about exterior containment structures, dumpster placement, or work hours. While HOAs don't issue building permits, non-compliance with HOA covenants could result in fines or delays.
Zoning
Zoning regulations in Justin and Denton County typically don't restrict mold remediation directly, but they can affect related work such as property modifications, shed or dumpster placement during remediation, and noise ordinances during construction hours. If your mold issue is tied to a commercial or mixed-use property, additional zoning permits may apply.
Historic Properties
Justin has several older homes that may fall under historic preservation guidelines, particularly if located near designated historic areas or districts. If your property has historic designation, additional approvals may be needed before any demolition or structural work can begin. Always verify with local planning authorities before proceeding.
