“Hostile living environment” is not a widely recognized legal term in the same way that “hostile work environment” is in employment law. If you mean to describe conditions where the living environment is intolerable or unsafe to continue living there, perhaps there could be claim. This could involve issues like harassment by neighbors or the landlord, significant maintenance issues that go unaddressed, or other factors that severely affect the tenant’s ability to live comfortably and safely in their rental unit. Here are a few ways to describe a hostile living environment in a legally cognizable way:

1. Constructive Eviction: If the conditions in the property is so unbearable that you are forced to leave, this could be considered a constructive eviction.

2. Breach of the Implied Warranty of Habitability: Landlords are required to ensure that rental properties meet basic habitability standards. If the living conditions are so poor that they violate these standards, the tenant could have a claim against the landlord.

3. Harassment or Retaliation: If the tenant is experiencing harassment from the landlord or retaliation for asserting their rights.

4. Nuisance: If a tenant’s quality of life is significantly impacted by neighbors or environmental conditions (like excessive noise, smells, or dangerous conditions), they might have a claim based on nuisance.

Whether you have a claim and what can be done about it ultimately depends on the specific details of your case.
