obligation to have road access; frontage requirement
Legal term under the Building Standards Act: a building site must touch a public road at least 4 meters wide for at least 2 meters of frontage.
This land cannot be built on because it does not meet the road-access obligation.
I asked the real estate agent about the frontage requirement.
Compound of 接道 (road access) and 義務 (obligation). The exact historical derivation is uncertain; the term is a modern legal coinage.
