Final answer:
A landlord generally cannot show a tenant's apartment without their permission, even if they own the building. Tenants have the right to privacy and exclusive use of their property. Landlords must provide notice and obtain consent before entering a tenant's unit.
Step-by-step explanation:
As a general rule, a landlord cannot show a tenant's apartment without the tenant's permission, even if they own the building. The right to privacy and the exclusive use of the property are important rights that tenants have, and landlords must respect those rights.
In most cases, landlords are required to provide notice to tenants before entering their unit and must obtain the tenant's consent. There may be exceptions in emergency situations or if the tenant has abandoned the property, but these situations are rare and specific laws vary by jurisdiction.
If a landlord enters a tenant's apartment without their permission and without a legal justification, the tenant may have the right to take legal action and seek remedies such as monetary damages or an injunction.
