How Far Away Can I Install My Generator from My Home?


Installing a standby generator is one of the smartest ways to protect your home during unexpected blackouts. When the power goes out, your generator kicks in automatically and keeps your routine going without interruption. But before installation day, you must learn the safe distance for Generac generator installation. Consider local building codes and practical tips so you know exactly how far to place the unit from your home.

Minimum Generator Installation Distance

Every generator installation must meet minimum generator placement codes set by the National Fire Protection Association (NFPA). These distances are about safety, serviceability, and efficiency. According to NFPA standards, you should:

  • Keep your generator at least 18 inches from your home.
  • Place the unit at least 60 inches from windows, doors, and other fresh air intakes to prevent carbon monoxide (CO) from entering your home.
  • Maintain 36 inches of open space in front of the unit for maintenance access.
  • Regularly trim vegetation growing within 36 inches of the generator. Plants must not exceed 12 inches in height.
  • Direct exhaust away from the home.

It’s important to note that while NFPA rules are national standards, local building codes may be stricter. For instance, some municipalities require placement at least 20 feet from any structure or property line. Verify the rules with local authorities before starting installation.

Other Factors That Influence Placement

While the clearances above set the minimum safe distance, here are other things to weigh before picking a spot:

  • Fuel source proximity: If your generator connects to a natural gas line, closer is better. Installing it near your gas meter and electrical panel limits the need for extra pipes and wiring.
  • Noise considerations: Even with today’s quiet models, generators make noise. Placing the unit farther from bedrooms and patio spaces reduces disruption.
  • Wind direction: CO safety is a must. Strong winds can push exhaust back toward your house, so it’s best to install the generator on the side opposite the prevailing wind.
  • Neighbor relations: Be mindful of property lines and noise ordinances. A unit too close to your neighbor’s windows could create problems.

Tips for Finalizing the Location

Determining the ideal generator placement involves balancing safety, cost, and comfort. Here are a few additional tips to keep in mind:

  • Follow manufacturer guidelines. Generac recommends a safe distance of at least 5 feet from your home.
  • Install the generator on a solid, level base, such as a concrete pad.
  • Avoid low-lying areas prone to flooding or soft soil that can’t support the generator’s weight.
  • Make sure technicians have room to walk around, inspect, and maintain the unit from all sides.
