Permit Requirements in Terlingua
Know when you need a permit to ensure your project is legal and safe
General Rules
In Terlingua (Brewster County, TX), mold remediation itself is not a separately licensed trade under county building codes. However, permits are generally required whenever the remediation involves structural repairs, demolition, drywall replacement, electrical work, or HVAC modifications.
The state of Texas regulates mold remediation through the Texas Department of Licensing and Regulation (TDLR). While a county building permit may not be needed for surface-level mold cleaning, any work that alters the structure or mechanical systems of a building will likely require a standard building or repair permit.
When Permits Are Required
A permit is often required in Terlingua when mold remediation involves:
- Removal or replacement of drywall, insulation, or subflooring beyond minor patching
- Structural repairs to framing, beams, or load-bearing walls damaged by moisture
- HVAC system remediation including ductwork replacement or cleaning that alters the system
- Electrical work such as replacing outlets, wiring, or panels affected by moisture
- Plumbing modifications to fix leaks that caused the mold
- Demolition of interior walls or ceilings exceeding a certain square footage
- New construction or additions tied to moisture remediation
Remediation triggered by a flood event or septic system failure may also require additional health or environmental permits from the county.
Common Exemptions
Permits may not be required for:
- Surface-level mold cleaning using non-toxic cleaning agents on non-porous surfaces
- Minor spot treatment of small areas (typically under 10 square feet) without structural changes
- Routine maintenance such as fixing a small leak and drying affected materials
- Inspection and testing only — simply testing for mold without performing remediation work
Important: Even if a permit isn't required, Texas TDLR regulations may still apply if you are hiring a licensed mold remediation company. Always confirm exemptions with Brewster County before proceeding.

Permit Process
1. Determine if your project needs a permit
Contact the Brewster County Building Department or visit their office to describe your mold remediation scope. Be ready to explain whether structural changes, drywall removal, or HVAC work is involved. This initial consultation helps clarify if a standard building permit or a specific trade permit is needed.
2. Prepare your application and documents
If a permit is required, you'll likely need to submit a building permit application along with a detailed scope of work. For significant structural work, you may need a contractor's bid, a description of the mold remediation plan, and in some cases, a moisture assessment or mold inspection report.
3. Work with licensed, code-compliant professionals
Texas law requires mold remediation companies and assessors to be licensed through TDLR. Your contractor should hold a valid TDLR mold remediation license. Using unlicensed contractors can result in fines, failed inspections, and liability issues.
4. Schedule inspections as needed
After work is completed, an inspection may be required to verify that structural repairs, electrical work, or HVAC modifications meet code. A final clearance inspection may also be needed to confirm the mold issue has been properly remediated.
5. Keep records of all permits and reports
Retain copies of your permit, inspection reports, and mold remediation documentation. These records are important for property disclosures, insurance claims, and future home sales. TDLR also requires licensed mold contractors to maintain records of all remediation projects.
Compliance Tips
- ✓ Always verify permit requirements with Brewster County before any mold remediation begins — what seems like a simple cleaning could trigger a permit if it involves structural work.
- ✓ Hire only TDLR-licensed mold remediation contractors. Texas state law requires a license for mold assessment and remediation, and unlicensed work can lead to fines and failed insurance claims.
- ✓ Get everything in writing: a detailed scope of work, a TDLR-compliant mold remediation plan, and a signed contract before any work starts.
- ✓ Don't skip the post-remediation inspection. Even if not required by the county, a clearance test by a licensed mold assessment professional provides peace of mind and documentation.
- ✓ If your mold issue stems from a plumbing leak or septic problem, you may need a separate plumbing or septic permit. Fixing the source of moisture is just as important as the remediation itself.
- ✓ Keep all permits, inspection reports, and TDLR documentation on file — they can protect you during future property sales or insurance audits.
Special Considerations
HOA Rules
If your Terlingua property is part of a homeowners association (HOA), you may need HOA approval before beginning mold remediation, especially if the work involves exterior modifications, changes to the building's appearance, or significant construction. Some HOAs also have rules about contractor parking, dumpster placement, and work hours. Check your CC&Rs and notify your HOA before starting any permit process.
Zoning
Brewster County's zoning regulations primarily apply to land use rather than construction methods, but commercial or multi-family properties may have stricter requirements. If your mold remediation involves a commercial building, rental property, or a structure in a floodplain, additional zoning or environmental permits may be needed. Always check with the Brewster County Planning and Development office.
Historic Properties
Terlingua is home to the Terlingua Historic District, which includes the old Terlingua mining town site. If your property is located within this historic district or is a designated historic structure, additional approvals from the Brewster County Historical Commission or the Texas Historical Commission may be required. Any exterior changes, structural alterations, or demolition in a historic district typically requires extra review and approval.
