⚡ PermitAssist vs. Calling Charlotte Building Department

💡 Pro Tips from Contractors

• Get the electrical AND gas permits at the same time — saves a second trip to the building department
• Confirm setback distance from windows and doors before ordering — some HOAs and cities are stricter than code minimum
• Size the gas line for peak BTU load including all other gas appliances on the same line
• In CA/SoCal: check CARB compliance before ordering the generator unit — some models are not permitted in certain air districts

• NC state license required: HVAC (Heating Contractor), Electrical (Electrician), Plumbing (Plumbing Contractor)
