Is it permissible for a landlord to charge a higher security deposit for a family with children?

The correct choice is the one stating that it is not permissible for a landlord to charge a higher security deposit for a family with children, as this would violate Fair Housing Law. Under this law, discrimination based on familial status is prohibited. This means that landlords cannot impose different terms or conditions on families with children compared to those without.

Charging a higher security deposit based on the presence of children would be considered a discriminatory practice, as it suggests that families with children are more likely to cause damage or wear and tear. Fair Housing Laws aim to provide equal treatment to all tenants regardless of their familial status, ensuring that families are not unfairly burdened by additional costs simply because they have children.

The other options suggest scenarios where additional charges could be justified, but they do not align with the principles of fair housing and equal treatment required under the law. Hence, the only correct understanding is that requesting a different security deposit based on the presence of children is prohibited.
