Permit Requirements in Round Rock
Know when you need a permit to ensure your project is legal and safe
General Rules
In Round Rock, mold remediation itself is not typically issued a standalone building permit from the city. However, Texas state law requires anyone performing mold remediation to hold a valid TDLR mold remediation license. Additionally, if the remediation involves structural repairs, drywall replacement, demolition, or changes to HVAC or electrical systems, those activities may require standard building, mechanical, or demolition permits from the City of Round Rock Building Inspections Division.
When Permits Are Required
A building permit from the city may be required when mold remediation involves:
- Structural repairs or demolition — Removing load-bearing walls, cutting into framing, or significant demolition often requires a permit.
- HVAC system modifications — If ductwork is replaced, rerouted, or if the HVAC system is altered to address mold, a mechanical permit may be needed.
- Electrical or plumbing work — Any rewiring, outlet relocation, or plumbing changes associated with moisture remediation typically require separate permits.
- New construction or additions — If remediation uncovers rot or damage requiring new structural work, a building permit may apply.
State licensing is mandatory. Texas law requires that anyone contracting for mold remediation for compensation be licensed by TDLR. Ask to see a company's TDLR license before any work begins.
Common Exemptions
Not all mold work triggers a permit. You may not need a city building permit if:
- The work is minor surface cleaning (less than 10 square feet of mold) with no structural changes.
- The remediation is performed by the property owner on their own primary residence (homeowner exemption from TDLR licensing, though you must still follow safe work practices).
- Work is limited to non-structural repairs like replacing a small section of drywall with no electrical, plumbing, or HVAC modifications.
Always verify with the City of Round Rock Building Inspections. Exemptions can vary based on the scope and location of the work.
✅ Usually Required
- ✓ New installations
- ✓ Major structural changes
- ✓ Electrical wiring updates
- ✓ Plumbing system extensions
⚡ Often Exempt
- ✓ Minor repairs and maintenance
- ✓ Replacing fixtures (same location)
- ✓ Painting and cosmetic finishes

Permit Process
Determine Scope of Work
Assess whether the mold remediation involves structural demolition, HVAC changes, electrical work, or plumbing. If so, a city building permit may be needed in addition to state TDLR licensing.
Hire a TDLR-Licensed Remediation Company
Texas law requires anyone performing mold remediation for compensation to hold a valid TDLR license. Verify the company's license status through the TDLR website before signing a contract.
Check with Round Rock Building Inspections
Contact the City of Round Rock to determine if your specific project requires a building, mechanical, or demolition permit. Provide details about the work scope for an accurate answer.
Submit Permit Application (If Required)
If a permit is needed, submit the application along with any required plans, scope of work documents, and fees. Licensed contractors familiar with Round Rock codes can handle this step.
Schedule Inspections
If a permit was issued, post-permit inspections may be required — especially for structural, mechanical, or electrical work. Coordinate with your contractor to ensure all work passes inspection.
Obtain Clearance (Post-Remediation)
After remediation, a licensed mold assessor (independent of the remediation company) should conduct post-remediation testing to confirm mold levels are within acceptable limits. This is a best practice often required for insurance claims.
Compliance Tips
- ✓ Always hire a TDLR-licensed mold remediation company — working without a licensed contractor can void insurance claims and result in fines.
- ✓ Ask for a written scope of work that clearly states what permits (if any) are required and who is responsible for pulling them.
- ✓ If mold is found during a renovation, pause the work and consult with a licensed mold assessor before proceeding with remediation.
- ✓ Keep copies of all permits, TDLR licenses, inspection reports, and post-remediation clearance testing for your records and future property disclosures.
- ✓ Verify independent post-remediation testing — the company that remediates should not be the same company testing the results to avoid conflicts of interest.
- ✓ Check with your homeowner's insurance provider early. Mold coverage varies widely, and some policies require pre-approval for remediation work.
Special Considerations
HOA Rules
If your Round Rock home is part of a homeowners association (HOA), check your CC&Rs before starting any exterior or visible work related to mold remediation. Some HOAs require approval for dumpster placement, exterior material changes, or visible construction activity. While interior mold work typically isn't restricted by HOAs, it's wise to notify your HOA if remediation requires exterior access or equipment.
Zoning
Zoning ordinances in Round Rock may affect mold remediation if the work involves commercial properties, multi-family dwellings, or structures near property lines. Commercial mold remediation projects may also need to comply with additional city business regulations. Always verify zoning requirements with the City of Round Rock planning department before starting work.
Historic Properties
Round Rock has historic districts and properties that may be subject to additional review. If your property is designated as historic or located in a historic overlay district, any exterior changes — and possibly interior structural work — may require approval from the historic preservation commission. Contact the City of Round Rock planning department before beginning mold remediation on a historic structure.
