The legality of your landlord refusing to wash and fold your laundry would depend on the terms outlined in your lease or rental agreement and the laws and regulations in your specific jurisdiction. In most cases, landlords are not required by law to provide laundry services such as washing and folding tenants' laundry.
When it comes to the responsibilities of a landlord, they typically involve maintaining the property's habitability and ensuring that essential utilities (such as water, heating, and electricity) are in working order. Providing laundry services is generally not considered a standard obligation of a landlord.
However, it's important to review your lease or rental agreement carefully, as some unique arrangements may have been included that could obligate the landlord to provide specific laundry services. If there are any specific laundry-related terms or agreements in your lease, they would be legally binding.
If you have concerns about the laundry facilities or any other aspects of your rental agreement, it's best to seek advice from a legal professional or a tenant's rights organization in your area. They can provide you with personalized advice based on the laws and regulations that apply to your specific situation.
