What is the minimum lot frontage length for an economic single-detached house on an irregular lot?

The minimum lot frontage length for an economic single-detached house on an irregular lot is set at 4 meters. This minimum requirement ensures that there is adequate space for both the construction of the house and the safe accessibility of the property. It also helps maintain uniformity in the streetscape and neighborhood character, which is important for urban planning and zoning regulations.

In the context of irregular lots, which may not conform to typical rectangular or square dimensions, the specified frontage length provides flexibility while ensuring that the property adheres to safety and functional standards. Having a standardized minimum prevents issues related to inadequate access or misalignment with neighboring properties.

The other options do not correspond with the regulatory frameworks that govern residential building practices for such properties. Therefore, knowing the minimum frontage length is crucial for compliance when planning the construction of a single-detached home.
