The requirement for rented apartments to have a refrigerator can vary depending on the location and local housing laws. In many places, there is no specific legal requirement for landlords to provide a refrigerator in a rented apartment. The inclusion of appliances like a refrigerator is usually left to the discretion of the landlord and is often outlined in the lease agreement.
In some areas or under certain housing regulations, there might be specific requirements for providing essential appliances like a refrigerator, especially for furnished apartments. However, for unfurnished apartments, it's more common for tenants to be responsible for providing their own appliances, including a refrigerator.
If you're looking to rent an apartment and are concerned about the availability of a refrigerator, it's essential to check the terms of the lease or speak directly with the landlord or property management to clarify what appliances, if any, are included in the rental unit.
