95% of the work can be done in overseas factories and is subject to the same globally competitive downward price pressure as every other manufactured good. Build them in Shenzen at a wholesale cost of $30,000 per pod, ship them to San Franciso for $2000, stack and install them at a cost of $8000. At 320 square feet, that's $120 per square foot. The same cost as new homes in rural Texas.
All the California legislature needs to do is pass a law zoning everywhere in the state for multi-story shipping container apartments. Then watch prices plummet. Even for single family regular construction homes, because the shipping container apartments will suck so much demand out of the market.
Modular apartment buildings also exist and can be thrown together quickly and affordably.
Not to be rude, but the problem is likely going to take a bit more to solve than throwing shipping containers at it..
$1000 a month for a brand new 740 square foot apartment in the middle of San Francisco. Plus with modern finishes that are frankly much nicer than anything you'll find in the low-end SF rental market. I'd imagine quite a lot of people would sign up.
This is mostly from an NYT article, so perhaps it's just one school if thought among many, but I found it convincing on the merits. https://www.nytimes.com/2019/08/14/opinion/shipping-containe...
I'm in a high-demand city in Canada. The house I'm in right now is worth about $70k. The land it sits on is worth $900k. Shipping containers aren't going to help with that.
Don't know where you live, but I doubt it's more expensive land than San Francisco, where the average acre of land costs $3.2 million[1]. Taking that acre of land, save half the area for green-space and courtyard. Use half the footprint for shipping containers. Stack the containers 8 high.
You now have 242 double-pod units. The amortized land cost per unit is $13,000. Assuming a generous rental yield of 12%, the land cost only adds $130 a month to the rent. That's hardly anything for a 720 square foot apartment.
The lesson is that even San Francisco land costs are no match for the power of high-rise high-density housing.

If cheap, abundant, shipping containers pull 25% of the demand out of the low-end multi-family segment, that's a 50% drop in prices. Low-end housing is a substitute good with mid-end housing for at least some of the demand.
The prime example are people who live with roommates in mid-end housing, who with cheap enough low-end prices, would get their own place. A 50% price shock to low-end multi-family at the very least would pull 10% of the demand out of the mid-end. That would lead to a 20% drop in mid-end multi-family prices.
Just the same there's at least some substitutability between mid-end multi-family and mid-to-high-end single family. A prime example are empty-nesters looking to downsize. With a 20% price shock to multi-family, that would suck at least 5% of the demand out of the single-family segment. That's a minimum of a 10% price reduction.
Hence a positive supply shock in the form of cheap, abundant shipping container homes would reduce the price of mid-high-end single family homes by at least 10%. This is all micro-econ 101.
