Earlier quoted context omitted.
This would seem to violate a tenant's rights to Quiet Use and Enjoyment, as is recognized by real estate law: https://www.landlordology.com/implied-covenant-quiet-enjoyme...
How so? I read your link and can't help to see it is about tenants rights, not visitors of tenants. It seems this would only stop non-tenets from having access to the facilities. At least without being accompanied by actual tenants.
That link is not the best. Quiet Enjoyment does cover the tenant's right to have visitors. A landlord cannot interfere with that right, including by blocking access to the unit by unaccompanied visitors who don't have the tenant's face.
