Where should you place a generator during an outage?
Choosing where to set up a generator during an outage affects safety, noise, and convenience.
This guide walks through safe placement basics and common mistakes to avoid.
Safe placement basics
For portable generators, most safety guidance recommends placing the unit at least 20 feet from doors, windows, and vents, with the exhaust pointing away from the home. This helps reduce the risk of carbon monoxide drifting inside.
Ventilation and surfaces
- Set the generator on a flat, stable surface like concrete or compacted gravel.
- Avoid areas where water pools or mud forms during heavy rain.
- Keep combustible materials such as leaves, cardboard, or fuel cans well away from the exhaust.
Avoiding fumes indoors
Never place a generator in a garage, shed, or covered area that doesn't have strong cross-ventilation. Carbon monoxide can build up quickly even if a garage door is cracked open.
