For a single-detached socialized house on an irregular lot, what is the minimum lot frontage length specified by BP 220?

The correct answer of 4 meters for the minimum lot frontage length of a single-detached socialized house on an irregular lot is specified by BP 220, which stands for the Bureau of Philippine Standards Act. This regulation is designed to ensure that residential properties have adequate access and a reasonable connection to public roads, thus facilitating transportation and provision of utilities.

Having a minimum lot frontage ensures that the house has enough visibility and recognition from the street, which is crucial for safety and community planning. A frontage of 4 meters strikes a balance between accessibility and the efficient use of land, encouraging well-planned development in residential areas.

Other options, such as 2 meters, 6 meters, and 8 meters, do not align with the intent of BP 220. A frontage of 2 meters may be inadequate for safety and access purposes, while 6 meters and 8 meters could result in unnecessary limitations on housing development, especially for socialized housing projects aimed at affordability and accessibility. Thus, the 4-meter requirement reflects a practical and regulatory approach to urban planning in residential settings.
