Which of the following is an exception to renters' rights?

Renters' rights are grounded in the principle that tenants have the right to live in a safe and habitable environment. An exception to these rights occurs when a particular issue does not directly impact the physical health or safety of the tenants.

For example, a minor cosmetic issue or a non-urgent repair that does not pose a risk to the tenant's well-being may not be addressed immediately by the landlord. This means that if an issue falls outside the scope of affecting physical health or safety, it may not trigger the same obligations and protections that more severe issues would, such as lack of heat during winter months or significant structural concerns.

The other choices describe situations that typically do not negate renters' rights. For instance, a lack of central heating directly affects tenant comfort and safety, a landlord being on vacation doesn't exempt them from resolving urgent issues, and having pets may be subject to lease agreements but is not a blanket exception to the rights of tenants.
