Space Heaters, Tenants, and Winter: What Property Managers Should Communicate

Every winter, a predictable pattern shows up in rental properties across the Puget Sound: a unit runs cold, a tenant buys a space heater at the hardware store, and nobody in the management office finds out until something goes wrong — a tripped breaker, a scorched outlet, or worse. The heater itself usually isn't the real problem. The absence of any communication about it is.

This isn't a call to ban space heaters or scare tenants into never using one. Used correctly, a modern space heater is a reasonably safe way to warm a cold room. The goal here is narrower: give property managers a clear, honest set of things to communicate before winter starts, so tenants know what's expected and you have a documented record if something does happen.

Why this needs to be said out loud

Most leases don't mention space heaters at all, which tenants reasonably read as silent permission. Left unaddressed, that silence means every tenant is making their own judgment call about placement, wattage, and how long it's safe to leave one running — with no guidance and no idea what your insurance or your building's electrical capacity can actually handle.

The risk isn't hypothetical fearmongering territory, but it also isn't a crisis that justifies a heavy-handed crackdown. It sits in the middle: a known, well-understood hazard that gets meaningfully safer with a few basic practices, and meaningfully riskier without them. That's exactly the kind of risk that a short, clear communication handles well — and that silence handles badly.

What to actually communicate to tenants

A single seasonal notice, sent before the heating season starts, covers most of what matters:

Why units run cold in the first place. If certain units or rooms in your portfolio reliably run colder — an older building, a room far from the furnace, a unit with known heating limitations — say so directly rather than letting tenants discover it and solve it on their own. Tenants who understand why a room is cold are more likely to ask for help instead of reaching straight for a heater as a permanent fix.

Basic placement and clearance rules. Keep space heaters on a hard, level, non-flammable surface — not on carpet, bedding, or furniture. Keep at least three feet of clearance from curtains, bedding, upholstery, and anything else that burns. This is the single most common cause of space-heater fires, and it costs nothing to state plainly.

Never leave one running unattended or overnight. This is the rule tenants are most likely to ignore if nobody tells them it matters, because an unattended heater looks fine — right up until it isn't.

Plug it directly into a wall outlet, not an extension cord or power strip. Space heaters draw enough current that extension cords and power strips not rated for that load can overheat. If a unit doesn't have an outlet near where heat is needed, that's a maintenance conversation, not a workaround for the tenant to solve with cord length.

Look for a heater with tip-over and overheat shutoff features. You're not in a position to approve or ban specific products, but you can recommend the baseline safety features worth checking for — most newer heaters have them, and it's worth saying so.

Report persistent cold rather than treating a heater as the permanent fix. This is the line that protects both sides. A space heater is reasonable as a short-term supplement; if a tenant is running one constantly because the unit's heating system genuinely can't keep up, that's a maintenance issue you want reported and tracked, not quietly compensated for room by room all winter.

What this protects you from

None of the above requires rewriting your lease or installing new systems. What it does is create a documented, reasonable standard that you communicated clearly and in advance — which matters if a heater-related incident ever does happen in one of your units.

Property managers who skip this step aren't usually the ones who get the brunt of blame when something goes wrong; tenants generally bear responsibility for how they use their own appliances. But "we never said anything" is still a weaker position than "we sent clear guidance every fall and it's part of our tenant communications," especially if an incident involves a shared wall, a common area, or a question about whether the unit's electrical capacity was adequate to begin with.

It also gives your team a legitimate, low-friction way to flag a real problem early. If a tenant reports that they're running a space heater nightly just to keep a bedroom livable, that's useful information — far better to hear it as a casual mention in response to your seasonal notice than to find out after a breaker trips repeatedly or a unit's heating complaint turns into something larger.

Where this fits with the rest of your heating-season prep

A space heater notice works best as one line item inside a broader heating-season communication, not a standalone warning that reads like a liability memo. If you're building out your fall-to-winter checklist for a rental portfolio, our guide on prepping rental properties for heating season covers the preventive maintenance side — furnace checks, filter changes, and the failures that actually generate the bulk of winter emergency calls. Pairing that checklist with a short, direct message about space heaters gives tenants the full picture: what you're doing to keep their unit warm, and what they should and shouldn't do if it still runs cold in the meantime.

If persistent cold complaints in a unit point to something beyond a space-heater stopgap — an undersized heating system, old wiring, or a unit that can't keep up no matter what's plugged in — our property maintenance team can assess what's actually driving it across properties in Bellevue, Kirkland, Bothell, Mercer Island, Issaquah, Sammamish, Redmond, and Seattle.
