Way back when the energy conservation movement began, some of the first devices available were flow restrictors. Disc with a hole in it that you fitted in just before the shower head or faucet. Reduced the amount of flow and saved water and energy. This was about 1980s.

both of these have been new apartments. And the first apartment was pretty bad for a number of reasons and figured just asses, but this place is a significant step up and not a lot of difference, hence me questioning codes. Thanks....

one just gets one at the hardware store (or from the utility) and then unscrews the shower head, sticks the restrictor in, and screws the shower head back on. So whether it's a new apartment makes no difference.

So the thing to check is just unscrew the shower head off, and I guess the restrictor will fall right out, or feel inside the pipe, see what you've got.

I can see apartments do this especially if saves them money or something but the thing we are mostly paying for water and not a little amount either. I already feel I am being screwed there. I will check it out or have son check it out, lol.

importantly, for our dire emergency burning-up planet, it saves on hot water (natural gas in my case) usage and the subsequent methane and CO2 emissions that come with it.

As I recall, these were pushed by utility flyers in the 1980's and maybe into the 90's as a conservation measure, and that one could request for free. Might still be, I haven't noticed in a long time.

That said, I didn't notice the difference before and after putting the restrictor in. Maybe makes a difference for people who like running their shower super full blast (and now they can't with the restrictor), but for me I'm happy with a good spray. Probably the restrictor isn't making a difference for me.

I've never made enough of an effort, but I would like to find some kind of lever thing that I can easily adjust the flow volume/strength, including all the way off, rather than doing so by turning the hot faucet handle and the cold faucet handle (separate handles) and getting that right so the temperature is right, and then repeating above in reverse when I want to adjust the volume back up. Kind of lazy and dumb of me now that I think about it to have not shopped for some kind of solution to this, but my life is such that I have time to do about 50% of the things I feel I should do, and this just had never made the 50% cutoff yet.

I just put it on my Amazon shopping list to at least read about what I can do (though after educating myself about my options, will prefer to get it at the local hardware store). Or just buy a freaking new showerhead with such a feature, should be easy to find. With a reference to this post

It can be deposits in the water pipes choking off flow. Are they metal pipes?

time finding a place I wanted to buy and was particularly aware of properties that had address plumbing and others thing previously. New apartments with both residents.

supply reservoir (water tank) to the point of use. That’s why water pressures are different for homes up on a hill vrs homes built closer (or below) sea level as compared to the supply point. In short, water pressure is determined by inches of water column (a little less than 1/2 psi per foot). I think it’s like .455 psi.

Minneapolis is pretty flat though and in NW and didn't have this issue but that doesn't always apply I am sure, to underground.

like the Art Deco one in Washburn Park. The city gets its water from the Mississippi using a series of pumps. https://www2.minneapolismn.gov/government/departments/public-works/water-treatment-distribution/treat-deliver/#:~:text=Our%20water%20comes%20from%20the,of%20drinking%20water%20each%20day.

Why was that necessary to supply the filtration system?

Good detail on the filtration but skipped over the delivery of the water after they treat it.

the Minneapolis system which in turn is pumped in from the Mississippi River. That said, we have a magnificent and functioning water tower at near 7800 Golden Valley Road (Winnetka and Golden Valley Road). I've always assumed it kept the system water pressure high and stable as well as functioning as a reservoir and buffer, but I'm not a water engineer.

is where all the kids used to go when I was growing up to smoke and drink. Now they've put a fence around it.

You can still get to it, though; there's a park around it.

Went to Washburn and never went up there with the "cool kids" but knew that's where they went.

and filled it with water the pressure at it’s end would be the same as the pressure at the bottom of Hoover damn regardless of the billions of gallons in the lake.

Mine is fine even in a hundred year old house. What floor are you on? This may sound strange but you can get a restricted shower head. It takes what pressure is available and sends the water out at the best possible strength. Sometimes they are called needle heads.

I can see part of the lake and sunset every night. I will explore. Thanks for the info.
