Explain me why these get rejected.

I have had several nominations rejected that should be accepted from my point of view.
For example this yoga gym/studio
It says its been rejected because of other criteria and that its on private property. Which is obvious that its not.
As to why it should have been accepted i wrote that it brings people together as well supports a healthy lifestyle and makes people get excersice.
Next up are two mini library.
For this one has been rejected as well because its on private property while its litteraly located at the sidewalk.
This mini library is rejected again for being on private property, and yes it is on private property but almost every mini library is. This one is just behind the tree you see on the 2nd picture and is reachable from the sidewalk.
So can anyone explain me why these were rejected?

Both little free libraries are attached to private residential property and are therefore invalid. It doesn't matter if it is "accessible" from a sidewalk. Nor does the fact that these are located at row houses instead of detached homes change their eligibility status. Any object on or attached to a private residence is not eligible.
For the little free libraries, even if they're accessible from the footpath, if they're on the property of a single family private residence (which includes being attached to the outward facing side of the property boundary), then they're considered to be on private residential property and should be rejected.
The yoga place could probably be eligible, but it's often hard to get businesses accepted.
Hoi @LordDroeftoeter-PGO
I have had a small surge of "Kinderzwerfboek" and other book boxes in my area as well, all of them hanging on the walls (or standing in yards) of private houses, all of them should be rejected as said.
As for the Yoga center: try to take a picture without the door's mail slot in the photograph, because there is a NO/YES sticker on it (telling what kind of advertisement is allowed to receive) and this sticker is typically used on private houses. It's specifically made to protect consumers from unwanted mail, not business (https://www.rijksoverheid.nl/onderwerpen/bescherming-van-consumenten/vraag-en-antwoord/wat-kan-ik-doen-tegen-ongewenste-reclame-en-folders-in-mijn-brievenbus)
I bet some reviewers saw the photo with the stickered mail slot, and it instantly triggered their PRP-reject muscle without checking the nomination further.
