I’d say it depends on how successful zombies are at breaking into places and how much supplies you have. And how long it takes for them to decompose enough to not be a threat.I don’t have the supplies to last long enough or if your hideout can withstand an assault for that long you’re going to have to relocate.

I’ve used this theory to negate all zombie apocalypse scenarios as they’d shred muscle tissues rapidly, and unable to recover it so at most a zombie could last a few days before being unable to move. If there was a ‘zombie’ outbreak it’d have to be while the person.
