I was actually looking into doing something similar, until I did actual research on bunker construction and underground housing, and learned how much of a tremendous pain in the rear end everything is. The redit guy commenting covered most of the high points. It's easier/cheaper to dig a bigass Olympic pool sized hole in the ground, build a 4 car garage out of those insulated concrete forms, then bury it than it would be to waterproof and strengthen a container to do something similar. Plus you can trivially waterproof the forms by gluing them together then tarring and tyvecing the outside.

At a minimum you need:

• True positive pressure ventilation, it must be battery backed up and have an audible warning in case the fan tachometer fails or power fails.
  
• Air mixing, via a fan, A/C filtration system, something to get the air column to stay mixed and able to be vented.
  
• Explosive gases, inert gases, CO, CO2, and oxygen level monitoring, with a regular calibration and testing. You can rig something up inside the air return plenum if you have an aircon style system, provided you can guarantee adequate mixing. Calibration on the sensors and alarm tests should be monthly or quarterly, depending on sensor type.
  
• Multiple ingress/egress. You need at least two ways in and out of an occupied structure, preferably ones that won't be blocked by the same tree falling on your hatch.
  
• Hatches that open outward need to be robust enough to open even with a tree or big rock on them, and able to be opened via hand pumped hydraulics or a screw type jack system. Any locking system you have in place on the outside, like a padlock hasp must fail when the hatch is opened from the inside.
  
• Fire suppression system, dry foam, water, something to put a fire out in a big loving hurry, because the O2 level will go from 'humans are cool here' to 'dead men tell no tales' in like a minute flat.
  
• Easy to access SCBA systems in case the sensors go off. gently caress all you can do in some cases, but at least you'll be conscious and able to act in the event the CO sensor goes off and keeps rising because some dipshit parked an idling tractor near an intake. Also training to put it on when tired as poo poo or just woken up, or possibly drunk as hell. That muscle memory could save your life.
  
• Loud as gently caress wake the dead alarms in place for fire/atmo issues, unless you've passed out due to a heroin OD, it should wake your rear end up.
  

After all that's said and done, and you still want your batcave apocalyptic nerd-bunker, go for it. Good luck getting an occupancy permit for it though, most municipalities will flat out deny you one. You might be able to argue with them and get a variance, especially if you follow the guidelines in the FEMA bunker pdf.

Pretty much. If your time is free, materials are scavenged, and maintenance nightmares until entropy converts it all back to iron oxide don't bother you, they can be a great 'deal'. As a lovely throw-away shed thing to store crap in, they work great, because that's what they were designed to do.

The answer to the housing crisis is well made apartment buildings with proper noise and vibration damping, with adequate underground parking for each tenant to have 2 vehicles plus a small storage space. Downside is asking for well made buildings during a housing crisis might as well be asking for blowjobs from a unicorn for how likely they are to actually occur.

Wow, that's a lot. Now why is very little of that needed with a basement? Is a basement inherently safer, or is this a case of requiring top-notch A+ safety measures when most cases of meeting code only need a B-?

2 parking spots per tenant seems insane. A huge part of the "housing crisis" is car-centric urban planning forcing the cost of construction up by requiring massive amounts of parking. A typical underground parking spot costs 30-60k, that's a huge savings to eliminate. In a lot of cities they're realizing strict parking minimums are working against both affordability and good urban planing and reducing or outright eliminating them, and there's a general consensus in urban planning today that parking minimums are a bad idea that have caused a lot of problems. Obviously that only works in places where you can live without a car, or just one car between a family. But it's actually a lot cheaper and more efficient to provide good transit and services within walking/bike distance than to force everyone to build massive parking structures and then massive highways to connect with shopping and workplaces with equally massive parking. It's the most land and resource intensive way to get around imaginable.

I understand the distance issues in Canada and the states, but if you're living in a population centre that has density problems you should be putting resources towards mass transit and accessibility, not filling perfectly liveable space with loving freeways that are traffic jammed 24/7.

Is literally a strap the pt to a spineboard and man handle them through the ladder hole with engine + ambulance crew you've got 6 people to do this. So if you live in the middle of nowhere I guess that could be an hour but anywhere civilized that's a 5-15 min response time. Guy says he's a firefighter at the end of the post so I would be slightly intrigued as to what he thinks is so complicated about this particular rescue he describes. Source: EMT with almost 7 years full-time and associated PT since then + rescue squad stuff.

A basement has a whole house over top of it for venting, it's not totally sealed under dirt. It's also made out of something reasonable like concrete that's been poured in place and sealed/insulated rather than the cheapest steel possible.

As a fellow EMT, I have to say that if you told me to climb down there I'd tell you to go gently caress yourself. Scene safety is the first priority and I'm not going down into that death trap for somebody that's, in all probability, already dead. That's a job for confined space rescue.

I'm pretty sure it's been posted in the thread before but yeah, you don't gently caress around with regular rescue attempts in enclosed spaces.
