I think even people advocating for required parking would concede that it adds to construction costs and reduces the total amount of housing available—but they’d presumably argue that there are other benefits offsetting those negative effects. This chart says nothing about what those benefits might be or whether the tradeoffs are worth it.
Omaha having a 5.3% population gain from 2017 to 2022 vs a 3.7% population gain in Minneapolis also probably plays a role as well… Yet Omaha was second most productive on creations on the left, and still prices increased rather than diminished.
Also, if you don’t have adequate parking space in an area, it results in cars spilling out into the nearest street parking.
That being said, if you want to increase housing density and you want available parking, you either gotta convert some low-rise buildings into parking and some into higher-density housing, or you gotta build parking garages, which cost substantially more than ground parking.
The cost per space varies based on the location and design of the parking garage.
A surface lot is $1,500-$10,000 per space (economical).
An above ground garage is $25,000-$35,000 per space (balanced).
An underground garage is $35,000-$50,000 per space (expensive from excavation).
Automated parking garages can vary greatly, but typically fall within the range of above-ground garages.
Any parking mandate adds to the cost of the housing. That being said, I generally think that that’s worthwhile (and frankly, my experience has been that parking mandates generally aren’t high enough for existing apartments). If you have a one-parking-slot-per-apartment mandate, you also have a number of people in those apartments who have multiple cars.

I do kind of wonder how much it would cost to do low-rise parking garages. Usually when I see them, they’re in high-value areas, downtowns and stuff, and very tall.
This has multistory parking garage construction costs for different locations. It looks like parking garage construction cost in San Francisco is about 50% higher than a lot of the country. I wouldn’t expect materials cost to vary much from state to state. Some of that is maybe earthquake code compliance. Some probably labor cost.
EDIT: One other point I’d add is that if you have one parking spot, it’s also possible to fit multiple motorcycles/mopeds in it. I know one person who was in an apartment who kept her motorcycle and another one in her parking space. Some places in (arid parts of) California are pretty amenable to motorcycle use.
EDIT2: If you figure, back of the napkin, that housing has an expected 10% ROI and the price difference between a surface parking slot and a multistory parking garage parking slot is maybe $25k, then it’s gonna increase annual rent for an apartment by maybe $2,500 or $208/mo, which I kinda suspect is gonna be rather outweighed by potential decrease in rent from more supply of housing being available; the price difference between “high demand area” housing and “low demand area” housing is a lot more than that.
The top four most-expensive US cities median rental price for a 1-bedroom apartment rental here are all in California: San Jose ($3,223), San Francisco ($2,705), San Diego ($2,534), and Los Angeles ($2,358).
The four least expensive cities are St. Louis, MO ($1,059), Cleveland, OH ($1,046), Oklahoma City, OK ($1,010), and Tulsa, OK ($994).
I’m no longer in California, but yeah. As the world heats up, people are going to want to have to walk less and less to get to their vehicle, and some places may even need covered parking (thinking about anyone near or in a desert, especially Las Vegas).
Also, not having to deal with having to find a spot that’s relatively close and safe.
Yeah. There are a few other differences between California and Minnesota other than “are you allowed to say ‘lol good luck and fuck you’ before unleashing hundreds of drivers to gobble up all the street parking with no analysis of whether that will lead to a shortage of parking for anyone, externalizing all the costs onto some other hapless bastard and making life worse for everyone?’”
In Japan, in order to register your car you need to prove you have a sufficient parking spot for it (they literally send an inspector to measure the space), or you can drive a tiny Kei car. Maybe we could learn a thing from Japan here.
Those who build apartments have a good idea how much parking is needed. They have incentive to figure it out because while it costs money to build parking it costs them when someone who wants parking decides to rent elsewhere where they can find it. Getting this balance right needs to be figured out for each block though, and so the city is too big to have a code.
As you point out, it costs money to build parking, but externalizing that cost is completely free. Since there is no block-by-block governmental structure that can enact regulations to stop people externalizing the costs individually, and the outcome of no one ever having any parking unless they pay to rent a space really isn’t ideal, I think having the city make parking zones and be aware of the problems and try to do something about them is a pretty acceptable substitute.

I would bet some of those places have land cheap enough that the parking costs almost nothing

Those benefits would be having a place to park.

That’s a lot of difference there to work with.

What could be done is underground parking, but that’d raise expenses by quite a lot, and land is cheap.
I mean I’m for it, but like you say it’ll increase costs exponentially for everyone involved.
Another solution would be separate parking garages. Where I live now, there are two free ones downtown where you can park all day.
