Quick Answer
Whole-house generators typically require special permits from local authorities, which may include electrical permits, building permits, or environmental permits, depending on the system's size and configuration.
Permit Requirements for Whole-House Generators
Permits are essential for ensuring that whole-house generators meet local safety and building codes. In the United States, for instance, the Federal Emergency Management Agency (FEMA) requires generators to meet specific National Electric Code (NEC) standards. Homeowners should contact their local authorities to determine the required permits and fees. In many areas, permit fees can range from $50 to $500, depending on the jurisdiction.
Generator Installation and Inspection
Proper installation is critical for safe and efficient operation. Hire a licensed electrician to install the generator, transfer switch, and electrical connections. Ensure the generator is installed at a safe distance from living areas and comply with local noise regulations. Many authorities require a post-installation inspection to verify that the system meets code requirements. This inspection may be conducted by the electrician or a local building inspector.
Permits and Inspections for Different Generator Types
The permit requirements vary depending on the generator type and system configuration. For example, a portable generator may not require a building permit, but a permanently installed standby generator will typically require a building permit and electrical permit. Additionally, some jurisdictions may require a special permit for generators over 10 kW or 10,500 watts. Homeowners should research specific requirements for their area and consult with local authorities to ensure compliance with regulations.
