True. I don't know how the market works in the US but in the UK what typically happens is a developer owns the land but borrows short term money to build on it.
The incentive, therefore, is to complete the project as quickly and cheaply as possible. Residential houses are designed for ease of building not for quality.
A typical buyer will have a 90-95% mortgage and the completed house is signed off by a surveyor who is engaged by the mortgage provider. The only real concern is if the house will still be standing in 25 years time and nothing else. In effect it's a rubber stamping process.
The buyer is often too emotionally involved in the concept of owning a home to care less.
No sane person would complete the purchase of a new car if defects in build quality were so glaringly obvious but the same people do it with houses every day?
That's what I meant by labor specialization - on the home-buying side, much fewer people can build a home or participate meaningfully in construction and remodeling.
The same cannot be said for houses. You live in a house everyday, but you don't have a true working or operating relationship with it unless you're very handy (which many home buyers these days are not). The car has a direct input/output operating cycle that you control; the house does not. It's harder to suss defects out because the house doesn't 'run' on them per se. You only learn about the defects when the house fails in one way or another. That may be two days into the inspection period, or it may be two years after closing.
Part of that was declining building standards (go too long between hurricanes and yes, people get complacent).
But another aspect, I think, is a shift in home ownership---we no longer "own" a home for an extended period of time (average length of owning a home in the US is seven years). Yes, my grandparents eventually paid off their mortgages, but nowadays I think that's pretty rare. Why buy quality when you aren't going to own for very long?
The one thing I will say for modern houses is that the wiring will generally be better and with outlets better spaced. They might be better insulated. But my goodness, the quality of the workmanship and often materials. We watched a house going up next to us, and had to think that big is a lot cheaper than good.
1. Labor specialization, meaning less of the home-buying market is savvy enough in the "handyman" sense to tell the difference. 2. A move away from building the thing you're going to own, and building things that other people will buy later. 3. Minimum standards for housing construction.
The third needs to be explained more - instead of aiming towards "building a good home", the construction industry aims to build the cheapest thing that they are legally allowed to sell (ie, meets building codes). While building codes do mean that there's a quality floor, competitive pressure means that nobody can consistently exceed the floor without getting out-competed by people who aim to barely meet it.
