How is the required living space calculated for children under 12 years old living in a dwelling?

The required living space for children under 12 years old is calculated as 50% of the required space for adults. This guideline recognizes that younger children typically require less personal space compared to adults while ensuring that they have adequate living conditions in a dwelling. The calculation for living space takes into consideration the developmental needs of children, who may be more comfortable in smaller areas while also allowing for efficient use of overall space in multi-family housing situations. By assigning a percentage that is less than that of adults, the regulation aims to create practical and suitable living environments for families, especially in urban settings where space may be limited.

The other options do not accurately reflect the established guidelines for space allocation: a zero space requirement would provide no living area for children, 75% would imply children require almost as much space as adults, and equal requirement as adults does not consider the differences in needs between age groups. This calculation thus strikes a balance between ensuring sufficient area for children to thrive and maintaining practical living conditions for families.
