What is the minimum lot area for an open market single detached house as per PD 957?

The correct answer is based on the provisions outlined in Presidential Decree No. 957, which governs the regulation of subdivision and condominium development in the Philippines. According to this decree, an open market single detached house must have a minimum lot area of 120 square meters. This requirement ensures that the property can accommodate the necessary living space and outdoor areas relevant to residential standards.

This minimum lot area is crucial for various reasons, including ensuring sufficient space for housing structure, yard, and necessary setbacks, which contribute to the overall quality of living. Adhering to these minimum area requirements is essential for compliance with residential zoning laws, promoting organized urban planning, and maintaining community standards.

The other choices, while they may represent common minimum lot sizes in some jurisdictions or developments, do not meet the specifications set forth by PD 957 for an open market single detached house. Hence, they do not align with the official legislative requirements for such properties.
