What is the maximum number of rowhouse units permitted per block cluster under PD 957?

The correct option indicates that under PD 957, the maximum number of rowhouse units permitted per block cluster is set at 20. This regulation is essential to ensure that developments maintain a certain density, which aligns with urban planning principles aimed at encouraging sustainable and manageable community growth.

By limiting the number of rowhouse units per block, PD 957 aims to prevent overcrowding and ensure that there is adequate space for infrastructure, services, and recreational areas. This kind of zoning regulation is typically designed to promote a balanced living environment, where residents have access to necessary amenities without feeling overwhelmed by the density of housing.

Understanding this limitation is crucial for anyone involved in the development of residential properties, as it directly impacts how developers plan and layout their projects to comply with local laws. Not adhering to this stipulation could result in penalties or a refusal of permits, thereby affecting the overall success of a construction project.
