Hi Udarian,
I added the private tag for consistency with other service roads and parking lot areas already existing in OSM. From street level imagery it appears that the two gated entrances n9884654407 and n9884654392 are closed to the public. While the main entrance near n9884654406 has a guard house at the entrance. There was no signage indicating No Trespassing or other access restrictions in street level imagery. It’s possible there are conditional access restrictions that are not posted when the street level imagery was captured. Let me know what you think.
