Permit Requirements in Castell
Know when you need a permit to ensure your project is legal and safe
General Rules
In Llano County and much of rural Texas, mold remediation does not always require a building permit for the remediation work itself. However, permits are often required for any repair, reconstruction, or demolition that follows the mold removal.
If your mold remediation involves tearing out drywall, removing structural components, replacing HVAC systems, or making electrical or plumbing changes, those activities typically fall under standard building, electrical, mechanical, or plumbing permit requirements.
When Permits Are Required
Permits are often required when mold remediation involves:
- Structural repairs or replacements (e.g., replacing framing, joists, or subflooring)
- Significant drywall or siding removal and replacement beyond minor patching
- HVAC system modification or replacement due to mold contamination
- Electrical or plumbing work necessitated by water damage or mold issues
- Demolition of interior walls or structures to access mold growth
- New construction or additions tied to water damage repairs
Additionally, if you are hiring a mold remediation company in Texas, TDLR requires that the company hold a Mold Assessment or Mold Remediation license for certain projects. Always verify that any contractor you hire carries the appropriate state license.
Common Exemptions
Small-scale, non-structural mold remediation may not require a permit if:
- The work involves cleaning surface mold from non-porous materials (tile, glass, metal)
- No structural components are removed or replaced
- No electrical, plumbing, or HVAC work is required
- The affected area is less than 25 square feet and can be cleaned without demolition
Even if exempt from a permit, safe work practices and proper mold containment are still strongly recommended to protect your health and property.

Permit Process
Step 1: Assess the Scope of Work
Determine whether your mold remediation will involve structural repairs, demolition, or mechanical system changes. If so, you'll likely need permits from Llano County. A licensed mold assessment professional can help identify the extent of contamination.
Step 2: Verify Contractor Licensing
In Texas, mold remediation companies must be licensed by TDLR for projects over 25 square feet. Confirm that any contractor you hire holds a valid Mold Remediation License and is familiar with Llano County permitting requirements.
Step 3: Submit Permit Application
For work requiring a permit, you or your contractor will need to submit plans and a permit application to the Llano County building inspection department. This typically includes a description of the work, scope of repairs, and any relevant contractor licenses.
Step 4: Schedule Inspections
After permitted work begins, inspections are generally required at key milestones — such as before closing up walls or after structural repairs are complete. A final inspection ensures the work meets current building codes.
Step 5: Obtain Final Approval
Once all inspections pass, a certificate of occupancy or final approval may be issued. Keep this documentation for your records, as it may be needed when selling the property or filing insurance claims.
Compliance Tips
- ✓ Always hire a Texas-licensed mold remediation contractor for projects exceeding 25 square feet of mold growth — it's state law.
- ✓ Take photos and document all mold damage before work begins. This helps with insurance claims and demonstrates compliance during inspections.
- ✓ Get permits before starting work. Unpermitted work can lead to fines, stop-work orders, and complications when selling your property.
- ✓ Ask your contractor to pull permits on your behalf — reputable, licensed pros typically handle this as part of their service.
- ✓ Keep all permit approvals, inspection reports, and contractor licenses in a safe file. These documents prove the work was done to code.
Special Considerations
HOA Rules
If your property in Castell is part of a homeowners association (HOA), you may need HOA approval before starting exterior repairs or structural changes. Some HOAs have specific rules about construction methods, materials, and appearance. Check your HOA covenants before beginning work.
Zoning
Llano County zoning regulations may apply if mold remediation involves significant changes to the property's footprint, structure, or use. Accessory structures, sheds, or detached garages affected by mold may need separate permits. Always check with the Llano County planning office before proceeding with major renovations.
Historic Properties
Castell does not have a designated historic district, but if your property is listed on or eligible for the National Register of Historic Places, additional review may be required before any alterations. Historic designations can affect how mold-damaged materials are repaired or replaced. Verify with the Texas Historical Commission if you have any concerns.
