🚫 Common Generator Permit Mistakes in Charleston

• Installing generator too close to windows or HVAC return air intake — carbon monoxide hazard and code violation
• Transfer switch work without permit — major code violation
• Not sizing gas line for combined BTU load (if other gas appliances on same line)
• Skipping the concrete pad requirement — some jurisdictions require permanent pad for standby units

💡 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
