What is a common requirement for all residential buildings regarding outdoor water access?

The requirement for residential buildings to have outdoor water access typically includes the installation of a hose bibb. A hose bibb is a type of outdoor faucet that allows homeowners to connect a hose for watering gardens, washing vehicles, or other outdoor activities. It is essential for providing convenient access to water outside the home, enabling effective maintenance of landscaping and facilitating various outdoor chores.

In most building codes, the inclusion of hose bibbs is mandated for practical use and safety, ensuring that homeowners can easily access water without needing to repeatedly carry it from inside the home. Other options, like sprinkler systems, sump pumps, and water softeners, serve specific purposes that may not be universally applicable to all residential buildings. Thus, having a hose bibb is a more standard requirement across diverse housing types.
