indeterminada/indefinida
sin peculiariedades / sin identificación
Se enfatiza que es un lugar "no identificado", "de características múltiples y variadas"..., por lo que podría ser cualquier sitio no identificado.
De ahí que usando "lugar no identificado", "ubicación no identificada", tal vez sea suficiente.
Si se quiere enfatizar con una repetición pleonástica, creo que sonaría redundante en español. Aunque se podría intentar algo del tipo: "ubicación no identificada de características indiscriminadas" o "lugar no identificado sin características peculiares"
"lugar no identificado sin características especiales"...
Saludos cordiales.

"Unnamed Storage Locations
A contractor might rent a storage location, such as a mini-warehouse, to store various personal property items. To eliminate the necessary requirement of reporting each such storage location to the insurer, a miscellaneous unnamed location endorsement can be purchased. This endorsement gives the contractor blanket coverage for various storage locations."
