Permit Requirements in Irwin
Know when you need a permit to ensure your project is legal and safe
General Rules
In Irwin and unincorporated areas of Union County, roofing permits are generally required when the work involves structural changes, decking replacement, or altering the roof's footprint or pitch. Simple repairs that don't affect the structural integrity may not need a permit, but it's always wise to check first.
When a permit is often required:
- Complete roof replacements (tear-off and re-roof)
- Structural modifications to rafters, trusses, or decking
- Adding dormers, skylights, or roof windows
- Changing roofing materials (e.g., going from asphalt to tile or metal)
- Commercial roofing systems with insulation or membrane changes
When a permit may not be needed:
- Minor repairs using matching materials (a few shingles or small patching)
- Cleaning or maintenance work that doesn't alter the roof structure
- Replacing gutters or downspouts (in most cases)
- Spot repairs addressing minor leaks without structural work
Always confirm with the Union County Building Department or Irwin's local zoning office before proceeding.
When Permits Are Required
Residential Roofing:
- Complete tear-off and replacement of roof covering
- Replacement of roof sheathing or decking beyond minor spot repairs
- Installation of new skylights, dormers, or roof penetrations
- Any work requiring changes to roof framing, trusses, or rafters
- Re-roofing that involves adding an additional layer over an existing one (some jurisdictions require permits for more than two layers)
Commercial Roofing:
- Full roof system replacement (membrane, built-up, metal, etc.)
- Structural recoating or re-covering that adds significant weight
- Installation of new HVAC units or rooftop equipment requiring structural modification
- Fire-rated assembly changes in commercial buildings
- Any work that alters the roof's load-bearing capacity
Both residential and commercial projects typically require a permit if:
- The work changes the roof's slope, height, or drainage pattern
- The project is part of a larger renovation that includes structural work
- The property is located in a floodplain or special hazard area
Common Exemptions
Some roofing work may be exempt from permit requirements, but exemptions are narrowly defined.
Potential exemptions (verify locally):
- Minor repairs using like-for-like materials affecting less than 100 square feet (exact thresholds vary)
- Replacing individual shingles or tiles to address isolated damage
- Routine maintenance like cleaning, coating, or sealing that doesn't involve structural changes
- Emergency tarping or temporary repairs done to prevent further damage (a permit may be required later for permanent work)
Important: Even if a permit isn't required, all work must still comply with applicable building codes. Licensed contractors familiar with local requirements can help determine if your project qualifies for an exemption.

Permit Process
Research & Determine Requirements
Start by contacting the Union County Building Department or Irwin's local permitting office to confirm whether your specific roofing project needs a permit. Have project details ready — scope of work, materials, and property location — so they can give you accurate guidance.
Prepare Documentation
Gather the necessary documents, which typically include a site plan, roof layout, material specifications, and sometimes engineered truss drawings. For commercial projects, you may need stamped architectural or engineering plans. Work with a licensed contractor who can prepare these documents correctly.
Submit Permit Application
Submit your completed application along with supporting documents and the applicable fee to the correct office. Applications may be filed in person, by mail, or online depending on local procedures. Make sure all information is accurate to avoid processing delays.
Plan Review & Approval
The building department will review your application to ensure it meets local building codes and zoning requirements. This may take anywhere from a few days to several weeks, depending on project complexity. Address any comments or revisions requested by the reviewer promptly.
Schedule Inspections
Once the permit is issued, work can begin. You'll need to schedule inspections at key milestones — typically after tear-off (to inspect decking), after underlayment installation, and upon completion. Your contractor should coordinate these inspections to keep the project on track.
Final Approval & Close-Out
After all required inspections pass, the building department will issue a certificate of completion or final approval. Keep this documentation for your records — it's important for property disclosures, insurance, and future resale value.
Compliance Tips
- ✓ Always verify permit requirements with the Union County Building Department or Irwin's local office before signing any contract — don't rely solely on a contractor's word.
- ✓ Work with licensed, bonded contractors who are familiar with Irwin and Union County permit processes. They should pull the permit themselves, not ask you to do it.
- ✓ Keep a copy of your approved permit on-site during all work. Inspectors may show up unannounced, and failing to produce the permit can result in stop-work orders.
- ✓ Schedule inspections at the right time — don't cover work that needs to be inspected before it can be approved. Your contractor should coordinate this.
- ✓ Document everything: permits, inspection reports, certificates of completion, and warranties. These documents are valuable when selling your property.
- ✓ If in doubt about whether your project needs a permit, ask. The cost and hassle of getting a permit are far less than dealing with fines, unpermitted work, or insurance issues later.
Special Considerations
HOA Rules
If your property in Irwin falls under a homeowners association (HOA), you may need separate approval beyond the building permit. HOAs often have covenants regarding roof colors, materials, and uniformity within the neighborhood. Get HOA approval in writing before starting any work — failing to do so could result in fines or having to redo the roof at your own expense.
Zoning
Zoning regulations in Irwin and Union County can affect roofing projects in several ways. Setback requirements, height restrictions, and stormwater management rules may apply — especially for commercial properties or major residential renovations. Check with the local zoning office early to confirm that your project is compliant before submitting your building permit application.
Historic Properties
Irwin and Union County have properties that may be listed on or eligible for the National Register of Historic Places. If your home or commercial building is in a historic district or is a designated landmark, additional review may be required before a roofing permit is issued. Historic preservation boards often have strict guidelines about materials, profiles, and installation methods to maintain the building's historic character.
