Priced out of the market to afford anything larger, and the other option is the streets. End of the day , some people are ok with living in a shitty dive for pennies on the dollar. Regulating 'Healthy homes' ultimately means the price is passed on from the landlord/ owner to the tenant. Here in NZ, the govt has been implementing 'Healthy homes' regulations for all rentals with things like 'mandatory' adequate floor ceiling insulation, elimination of drafts in windows and doors, extractor fans in all kitchens and bathrooms, heat pump in main living area/ lounge etc. The rents across the entire country have skyrocketed in the last 3-4 yrs bc of it. People rent what they can afford but now there are actually zero low price options even if one wanted to and what other options is there if you can not afford an out of budget house/ flat - you end up couch surfing / in a garage or sleeping in a car - pity those with children on top.
