I feel the entire housing industry needs investment and modernization.
More people being born, input costs will keep going up.
We should reconsider certain requirements such as outlets on outward facing walls.
Copper is expensive, and if we want to better insulate our houses it would be easier if there wasn't wiring on the outside walls contributing to leakage.
Adopting the widest stud distance when framing, again less heat loss through the studs and less lumber.
We need to stop with the detached homes and instead build up. Taxes drop when more people are sharing the burden. Less asphalt, less high voltage lines, less sewers, more efficient bus routes, and better thermally insulated as there's more shared walls.
We need to see heat pumps installed by default in new units.
We need rental terms to prevent renovictions, but at the same time help the home owners losing money because if higher mortgage rates. Maybe subsidize mortgage rates in exchange for 5 year rental terms. The thinking here is people raising a family can feel stable renting.
We need enough investment into mass transit that people feel confident in ditching automobiles if they can. Cars can easily account for 33% of a person's income.
