Permit Requirements in Big Wells
Know when you need a permit to ensure your project is legal and safe
General Rules
In Big Wells and unincorporated Dimmit County, building permits are generally not required for basic mold cleanup that involves only cleaning and surface treatment of non-structural materials. However, permits may be required when the remediation involves removing and replacing drywall, insulation, framing, or other building materials that constitute a structural repair or alteration.
The key threshold is whether the work goes beyond simple cleaning into construction, demolition, or reconstruction. If you're cutting out sections of wall, replacing subflooring, or repairing structural damage caused by moisture — those activities often trigger local permit requirements.
When Permits Are Required
A permit may be required in Big Wells for mold remediation work that includes:
- Structural repairs — Replacing studs, joists, load-bearing beams, or roof sheathing affected by rot or mold
- Significant demolition — Removing large sections of drywall, ceiling, or flooring
- New construction work — Rebuilding walls, installing new ventilation systems, or adding moisture barriers
- Electrical or plumbing modifications — Any mold-related work that involves moving or altering electrical, plumbing, or HVAC systems
- Commercial properties — Mold remediation in commercial buildings may face stricter local inspection requirements
Additionally, any mold remediation performed in Texas must comply with TDLR licensing rules if the affected area exceeds 25 contiguous square feet.
Common Exemptions
Permits are typically not required for:
- Small-scale mold cleanup (under 25 sq ft) involving surface cleaning only
- Minor spot treatment of visible mold on non-structural surfaces
- Routine maintenance and cleaning that doesn't involve replacing building materials
- Work performed by a homeowner on their own single-family residence (though TDLR licensing rules may still apply in certain circumstances)
Always verify with the local building authority — exemption thresholds can vary, and it's better to confirm than risk a violation.

Permit Process
Step 1: Assess the Scope
Determine the extent of mold growth and any underlying structural damage. If the affected area exceeds 25 contiguous square feet in Texas, TDLR-licensed mold assessment and remediation professionals are required by state law.
Step 2: Check Local Requirements
Contact the Dimmit County building department or the City of Big Wells municipal office to ask whether a permit is needed for the specific remediation work planned. Be prepared to describe the scope — simple cleaning vs. structural repair makes a significant difference in requirements.
Step 3: Hire Licensed Professionals
If the mold issue is significant, state law requires hiring a TDLR-licensed mold assessment company and a separate TDLR-licensed mold remediation company. These professionals will understand both state licensing rules and local permit requirements.
Step 4: Submit Permit Application (If Needed)
If local codes require a permit, you'll typically submit an application with a scope of work description, contractor information, and possibly engineering or moisture remediation plans. Fees are generally based on the value of the repair work.
Step 5: Schedule Inspections
After remediation and any reconstruction work is complete, a local building inspector may need to sign off on the work. A post-remediation clearance inspection is also required by TDLR rules for projects over 25 square feet.
Step 6: Maintain Records
Keep copies of all permits, inspection reports, TDLR licenses, and remediation documentation. These records are important for property disclosures, insurance claims, and future home sales.
Compliance Tips
- ✓ Always confirm permit requirements with the Dimmit County building department before any work begins — even small remediation jobs can trigger requirements if structural materials are removed.
- ✓ In Texas, mold remediation of areas over 25 contiguous square feet must be performed by a TDLR-licensed remediation company, and a separate TDLR-licensed mold assessor must perform the initial inspection and final clearance testing.
- ✓ Don't assume a permit isn't needed just because the work is interior — replacing drywall, insulation, or framing still counts as construction in most jurisdictions.
- ✓ If insurance is covering your mold remediation, check with your adjuster about documentation requirements — unpermitted work could affect your claim or future coverage.
- ✓ Work with contractors who are familiar with both TDLR regulations and local Dimmit County building codes to ensure all compliance bases are covered.
- ✓ Post-remediation clearance testing is not just a regulatory requirement — it's your proof that the mold issue has been properly resolved and your home is safe.
Special Considerations
HOA Rules
If your Big Wells home is part of a homeowners association (HOA), you may need to notify the HOA before beginning exterior or visible mold remediation work, especially if it involves changes to the structure's appearance. Some HOAs have architectural review committees that must approve any construction-related work. Check your HOA covenants, conditions, and restrictions (CC&Rs) for specific notification or approval requirements.
Zoning
Zoning regulations in Big Wells may affect mold remediation work, particularly if it involves alterations to the building footprint, new construction, or changes to exterior features. Commercial properties may face stricter zoning compliance requirements. Additionally, if the remediation is related to flooding or drainage issues, there may be local floodplain management regulations that affect reconstruction work.
Historic Properties
Big Wells and Dimmit County do not have large designated historic districts, but if your property is listed on the National Register of Historic Places or located in a potential historic area, additional approvals may be needed. Historic preservation rules may restrict how much original material can be removed and what replacement materials can be used. Always verify with the Texas Historical Commission if you suspect your property may have historic designation.
