Permit Requirements in Castroville
Know when you need a permit to ensure your project is legal and safe
General Rules
Permit requirements for mold remediation in Castroville depend on the extent of the work. Simple mold cleanup on non-porous surfaces often does not require a permit. However, if remediation involves demolition of drywall, removal of structural materials, or modifications to plumbing, electrical, or HVAC systems, a building permit may be required.
Licensed mold assessment and remediation is regulated at the state level in Texas by the Texas Department of Licensing and Regulation (TDLR). In many cases, the contractor handling the remediation should hold the appropriate TDLR license for mold remediation.
Always verify with the City of Castroville Building Department or Medina County permitting office for local requirements.
When Permits Are Required
Permits may be required when mold remediation involves:
- Removal or replacement of drywall, insulation, or structural lumber affected by mold
- Modifications to HVAC systems (ductwork replacement, air handler changes)
- Plumbing repairs to fix the moisture source (leaking pipes, drainage issues)
- Electrical work near water-damaged areas
- Structural repairs to framing, subflooring, or load-bearing elements
- Commercial or multi-family properties where occupancy or fire safety classifications may change
Large-scale remediation projects often need a permit because they cross over into general construction, electrical, or mechanical work.
Common Exemptions
Permits may not be needed for:
- Small, surface-level mold cleanup on non-porous materials (tile, glass, metal)
- Cleaning areas under 10 square feet (routine maintenance)
- Temporary moisture control measures (placing dehumidifiers or fans)
- Cosmetic repairs like repainting after the mold source is resolved
Even if a permit isn't required, all work should still follow industry standards for safety and containment. When in doubt, check with local authorities to be sure.

Permit Process
1. Determine the Scope of Work
Assess how much material needs to be removed and whether any structural, electrical, plumbing, or HVAC work is involved. This determines if a permit is needed.
2. Contact Local Permitting Office
Reach out to the City of Castroville or Medina County permitting office to ask about specific requirements for your project. Have details ready about the size of the affected area and the planned repairs.
3. Hire a Licensed Mold Remediation Professional
Work with a TDLR-licensed mold remediation company. Many licensed professionals include permit handling in their service — they pull the necessary permits on your behalf.
4. Submit Permit Application
If a permit is required, the application typically includes a scope of work, materials to be used, containment plans, and disposal procedures. The contractor or homeowner may submit this.
5. Schedule Inspections If Required
After remediation work is complete, an inspection may be needed to confirm the mold has been properly removed, moisture issues resolved, and any structural repairs meet code.
Compliance Tips
- ✓ Always hire a TDLR-licensed mold remediation contractor — Texas law requires licensure for mold remediation exceeding certain thresholds.
- ✓ Get a pre-remediation assessment from a licensed mold assessment consultant (separate from the remediation company) for larger projects to document the scope.
- ✓ Keep all permits, inspection reports, and remediation documentation — these may be needed for real estate disclosures when selling your home.
- ✓ Address the underlying moisture source (leaky pipe, foundation crack, roof leak) before or during remediation to prevent mold from returning.
- ✓ Don't skip the permit check — unpermitted remediation work can cause issues during home inspections, insurance claims, or property sales down the road.
Special Considerations
HOA Rules
If your Castroville property is part of a Homeowners Association (HOA), check your CC&Rs before starting work. Some HOAs have rules about exterior changes, dumpster placement, or contractor vehicle parking. While HOAs don't issue building permits, they can delay work if approvals aren't obtained first.
Zoning
Zoning regulations in Castroville may affect mold remediation projects, especially for commercial properties. Waste disposal of moldy materials, noise restrictions during work hours, and property line setbacks for any exterior modifications may apply. Check with the City of Castroville zoning department for property-specific requirements.
Historic Properties
Castroville is home to the Castroville Historic District, known for its Alsatian-style architecture. If your property is in a historic district, additional approvals may be required before any demolition or structural work. The Castroville Historic Preservation Commission may need to review plans to ensure the historic character is preserved. Always confirm historic district status before starting remediation.
