who consented to the conditions of your house when entering. If he is not sure he ought to hire a civil engineer to inspect and verify the safety status of the house or ask the host to do it.

this is the only legitimate case for regulation, to protect the public and/or third party.

This is not a problem of housing but of manners. You can get rid of hot soup without infringing of other people's ability to walk around the public area and not be wet.
I think the solution is to move away from cities. I'm planning to do so. I'm just going to be sad if it means leaving my country because you don't want me anywhere near you, even if it means I'm on the horizon from your window.
In the UK if you want a house but are completely agnostic about where, there's Stoke-on-Trent; the council were selling houses for £1 on the condition that the new owner renovated them to code. Otherwise, rural living in Scotland is also quite cheap.
I would far rather have a home that has 'risky banister railings' if that meant I could actually afford it.
Mental health is as important as physical health, if not moreso - what's worse, risk of eviction, or having to pay attention near the stairwell? I get that this is an isolated example, but I'd take worse insulation, no solar, worse security, everything, if it meant I could get a home and slowly improve it myself with time.
If that means I have to live rurally - so be it - but as far as I can tell that means living outside of the country I was born in (UK), which is quite sad.
