"adopt strategies to create some turnover" is a very polite way of saying fine people and tow their cars, ruining their days and sometimes their lives.

In most cases each apartment block have it's own parking lot off the street. Wether it's 5, 50 or 100 years old. Many streets are too narrow for parking on both sides. Tiny lots either cause spill over to other parking lots nearby or illegal parking on the greenery or in the street (illegal because street is too narrow for parking).

A recent example.. There was a mall with a parking lot, not too small not too big. A new apartment building was built. One of their selling points was huge free parking nearby. Mall was pissed off that their parking lot is full and customers can't find a spot and installed barriers to prevent overnight parking (2 or 4h free, longer - €€€). Now people who bought apartments are pissed because they were told the parking lot was public (= gov-owned). Mall customers are pissed because barriers is inconvenience. Mall is pissed because operating barriers cost them extra money. City is pissed because suddenly they have a load of cars on narrow street nearby. The only ones who won are the sleazy developers.

Another issue is small apartment blocks built in single-family houses quarters. Tiny streets over there can easily take a car or two in front of each house. Then suddenly a 6-apartment building comes up and there're 10 cars in front of a property that'd otherwise have 1 or 2 cars. This happens in rather remote suburbs mind you.
