. "Reserved parking" is the term you want. It is clearly marked here as such.

I agree with regular (long-term) parking It can even be used for small boats and trailers. The idea is regular and long-term.

Just for information: stalling 'Stalling' can also be used for long-term parking, such as caravans/trailers. Renting out space for 'Caravanstalling' is an extra source of income for many farmers, for example. Also, there are many 'garageboxen' used for 'long-term parking', for convertibles in the winter season. Just to add a little information :-)

private parking garage is my current thought, confirmed a little by Writeaway's reference.
