Placement and Weather, at a Glance

Where you set a generator down — and how you handle it in rain, snow, heat, or a flood warning — matters almost as much as the machine itself. This guide covers picking a genuinely safe spot, running-rated covers versus dangerous enclosures, and handling every kind of weather without cutting corners. There's a printable page-by-page version up top.

Common Questions

1 How far does a generator need to be from the house?

At least 20 feet, on firm, dry, level ground, with the exhaust pointed away from every window, door, vent, and your air conditioner's outdoor intake — and away from the neighbor's windows and doors too. See our carbon monoxide guide for the full safety rule behind this distance.

2 Can I use a canopy or tent to keep the rain off?

Yes, if it's specifically rated for use while the generator is running and leaves real airflow on every side. Never use a sealed tarp, storage shed, or any fully enclosed structure — that traps deadly exhaust around the machine.

3 Is it safe to run a generator in the rain?

Under a proper running-rated cover, on dry firm ground, ordinary rain is usually fine. In heavy or wind-driven rain, or if water starts pooling nearby, power it down and let things dry out.

4 What about flooding?

Never run a generator in standing water, and move it to higher ground well before rising water gets close. If water does reach a running unit, don't touch it, its cords, or the water around it until everything is confirmed safe.

5 Does heat cause any placement problems?

Mainly one worth knowing: a generator's muffler runs hot, and setting it on dry grass, mulch, or leaves in hot weather is a real fire risk. Choose bare ground, gravel, or pavement instead.

6 What should I do about noise and security?

Distance and a hard surface soften noise, and pointing the unit away from bedrooms — yours and the neighbor's — helps too. For security in a long outage, cable and lock it to something solid and avoid leaving it in plain view from the street.

Would you rather I just do this for you?

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.

Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
