Most disaster prep content — including a lot of what's on this site — assumes you own your home and have a yard to put a generator in. If you're renting an apartment or condo, a lot of that advice simply doesn't apply, and pretending otherwise leaves you underprepared. Here's what actually works within the real constraints of renting.
Why a Gas Generator Isn't an Option (And Why That's Fine)
Gas generators and apartment living are fundamentally incompatible, for reasons that go well beyond inconvenience:
- Almost every lease prohibits them. Most residential leases explicitly ban gas generators and fuel storage on the premises. Even leases that don't mention generators by name typically cover it under fire hazard or structural modification clauses. Violating this risks lease termination.
- Carbon monoxide risk is amplified indoors and in shared buildings. A generator that's dangerous near a single-family home is far more dangerous in a building where CO can migrate between units.
- The noise is a real problem, not just an annoyance. A standard gas generator runs at 65-75 decibels — comparable to a running vacuum — continuously, through shared walls, floors, and ceilings. That's a fast path to noise complaints and neighbor conflict even where it's technically allowed.
- Fuel storage is typically banned outright. You can't legally keep gasoline containers in an apartment, on a balcony, or in most shared storage areas.
The good news: none of this is actually a gap in your prep. It just means the right tool for renters is different, not worse.
The Right Tool: A Portable Power Station
A battery-based power station solves every problem a generator creates for renters:
- Zero emissions — safe to run in a living room, bedroom, or kitchen with no ventilation concerns
- Silent or near-silent — most run under 40dB, quiet enough that neighbors won't know it's on
- No installation, no permission needed — it's legally a portable appliance, not a generator. If asked, "it's a portable backup battery, like a big power bank" is an accurate, simple answer
- Moves with you — when you move apartments, unplug it, carry it out by the handles, and set it up at the new place
Sizing It Right for an Apartment
Don't oversize this the way you might for a house — footprint, weight, and price all matter more in an apartment than they do in a garage. For most apartments, a 1,000–2,000Wh power station covers the real essentials through a standard outage:
- A mini-fridge (100-200W) or full-size fridge (150W average) — roughly 4-8 hours of fridge runtime per charge depending on unit size, more if you're conservative about opening the door
- Wifi router and phone charging
- A CPAP machine (30-60W) — comfortably covers multiple nights on a mid-size unit, one of the clearest cases where a battery genuinely matters
- A fan for airflow during a summer outage
- LED lighting
If you want to run more than that, or want multi-day coverage rather than a single overnight, step up toward the 2,000Wh+ range — see our best portable power stations guide for specific picks across budget tiers.
Ask Your Building One Question Before You Need It
Don't wait for an actual outage to find out your building's backup situation. Ask your leasing office or building engineer directly: "Does the building generator feed tenant unit panels, or only common-area and life-safety systems?" A lot of buildings advertise "we have a backup generator" in a way that sounds reassuring but only keeps hallway lights and elevators running — not your actual apartment. Knowing the real answer now means you're not caught off guard later.
What Else to Have Ready
- 72 hours of no-cook food and 3 gallons of water per person, since you likely can't cook without power and may not have outdoor grill options
- A charged power bank (10,000mAh+) as backup to your main power station, for phones specifically
- A battery-operated radio and headlamp
- Copies of your lease, ID, insurance, and prescriptions in a waterproof bag — see our emergency documents guide for the full list
- Cash on hand — ATMs and card readers fail without power
- A plan to relocate if an outage stretches past 48 hours or temperatures become extreme — know in advance where you'd go (a cooling/warming center, a friend's home, a hotel), rather than figuring it out mid-crisis
