Permit Requirements in Lewisville
Know when you need a permit to ensure your project is legal and safe
General Rules
In Lewisville, a building permit is generally not required for mold remediation alone — that is, simply cleaning and removing mold growth. However, permits are often required when the remediation involves:
- Structural repairs (replacing drywall, framing, subflooring)
- Electrical or mechanical work (replacing HVAC equipment or ductwork contaminated by mold)
- Plumbing work (repairing leaks that caused the mold)
- Major renovations triggered by mold damage
The City of Lewisville follows the International Building Codes, and any construction activity beyond surface-level cleaning may trigger permit requirements.
When Permits Are Required
Permits are most often required when mold remediation involves:
- Drywall replacement — cutting out and replacing large sections of wallboard
- Structural framing repairs — replacing studs, joists, or other load-bearing elements
- HVAC system replacement or ductwork modification — addressing mold in the air handler or duct system
- Electrical work — repairing or replacing wiring damaged by moisture
- Plumbing repairs — fixing leaky pipes that caused the mold issue
- New construction or additions — building out replacement structures after mold removal
Additionally, Texas state law requires that mold remediators hold a TDLR license for projects involving more than 10 contiguous square feet of mold removal. Always verify that your contractor carries the appropriate state license.
Common Exemptions
Permits may not be required for:
- Minor spot cleaning of mold on non-porous surfaces (under 10 sq. ft.)
- Testing and inspection only without any construction or repair work
- Surface-level cleaning with antimicrobial treatments that doesn't involve removing building materials
- Small patch repairs to drywall (typically under a few square feet) — though local rules vary
Important: Even if a building permit isn't required, Texas state regulations still require proper licensing and work practices for any significant mold remediation. Always confirm with the City of Lewisville's building department before starting work.

Permit Process
Determine scope of work
Identify whether your mold remediation involves cleaning only or also includes structural repairs, drywall replacement, or HVAC work. This will determine if a building permit is needed alongside state-mandated mold remediation licensing.
Verify contractor licensing
Confirm your mold remediation contractor holds a valid TDLR Mold Remediation License. For projects requiring construction work, also verify their general contractor license and insurance. Licensed professionals will know when permits are needed.
Check with Lewisville Building Department
Contact the City of Lewisville's building inspections division to ask whether your specific scope of work requires a permit. Provide details on the extent of mold damage and planned repairs. When in doubt, it's always safer to ask.
Submit permit application
If a permit is required, your contractor will need to submit an application with detailed scope of work, material specifications, and sometimes engineered drawings for structural repairs. Fees are typically based on the estimated value of the work.
Schedule inspections
Once the permit is issued and work begins, the city will require inspections at key milestones — typically before walls are closed up, after electrical or mechanical work, and upon completion. Never cover up work before it's been inspected.
Final approval and documentation
After all inspections pass, the city will issue a final approval. Keep this documentation for your records — it may be required for insurance claims, future home sales, or HOA compliance.
Compliance Tips
- ✓ Always verify your contractor's TDLR license before signing any mold remediation contract — Texas law requires it for projects over 10 sq. ft.
- ✓ Ask your contractor upfront whether they will pull permits for any structural work involved. A code-compliant pro will handle this as part of their service.
- ✓ Don't cover up mold damage with new drywall or flooring before all necessary inspections are complete — this can lead to permit violations and costly rework.
- ✓ Take photos of the mold damage and remediation process for your insurance records. This documentation can help with claims and permit compliance.
- ✓ If your mold issue stems from a leak, address the source (plumbing or roof repair) separately — those repairs may need their own permits and inspections.
- ✓ Keep all permits, inspection approvals, and TDLR paperwork on file. These documents may be needed when selling your home or filing insurance claims.
Special Considerations
HOA Rules
If your Lewisville home is part of a homeowners association (HOA), check your HOA's guidelines before starting mold remediation. Some HOAs require prior approval for exterior work, dumpster placement, or any visible changes to the property. Certain HOAs near Lewisville lakes or planned communities may have additional restrictions on construction noise, work hours, and contractor access.
Zoning
Zoning regulations in Lewisville may affect mold remediation projects, particularly for commercial properties or multi-family dwellings. Check whether your property's zoning allows for the type of construction work involved. Setback requirements, property line restrictions, and dumpster placement rules may also apply. Commercial mold remediation projects often face stricter zoning scrutiny than residential ones.
Historic Properties
Lewisville has a number of older homes and properties near the historic Old Town district. If your property is designated as historic or located within a historic overlay zone, additional permits and design review approvals may be required before any structural repairs or alterations begin. Work must typically preserve the historic character of the building. Verify with the city's planning department if your property falls under historic preservation rules.
