Generator Placement: How Far From Your House Is Safe & Smart?

Installing a Generac whole home generator is one of the smartest ways to protect your home from unexpected power outages. But before installation, one of the most important questions we answer at McCay Southern Generators is:“How far from my house should the generator be placed?”

The right placement is not only a matter of safety—it also affects performance, convenience, and compliance with local codes. Let’s break it down.

Why Generator Placement Matters

Placing your generator in the right location ensures:

• ✅ Safety: Protects your home from carbon monoxide buildup.

• ✅ Efficiency: Keeps your generator running smoothly without obstruction.

• ✅ Longevity: Reduces wear by keeping the unit away from excess heat or debris.

• ✅ Code Compliance: Meets manufacturer guidelines and local building regulations.

How Far Should a Generator Be From Your House?

The National Fire Protection Association (NFPA) and Generac installation guidelines recommend:

• At least 18 inches (1.5 feet) from the exterior wall of your home.

• At least 5 feet from windows, doors, and vents (to prevent carbon monoxide from entering your home).

• Clear airflow on all sides—generally 3–5 feet of space around the unit for maintenance access and ventilation.

⚡ Pro Tip: Local codes in East Tennessee may have additional requirements, so professional installation is key. At McCay Southern Generators, we handle all permitting and code compliance for you.

Best Locations for Generator Placement

When choosing where to place your generator, consider:

1. Near the Electrical Panel & Fuel Source

   • Shorter connections mean easier installation and faster transfer of power.

2. Stable, Level Ground

   • A concrete or composite pad prevents shifting and protects against flooding.

3. Away From Bedrooms & Living Spaces

   • Reduces noise and ensures better airflow.

4. Accessible for Maintenance

   • Technicians need clear space for servicing, oil changes, and inspections.

Mistakes to Avoid

❌ Placing the generator directly under windows, vents, or decks.❌ Installing too close to shrubs, fences, or sheds (blocks ventilation).❌ Skipping a proper foundation pad (leads to instability).❌ Ignoring local permitting rules and safety codes.
