The Seoul Metropolitan Government said Wednesday that it will now recommend all residential buildings with 30 or more stories have at least two elevators.

The guideline was sent to construction and architecture companies currently preparing to submit reviews of their apartment projects, the city officials said.

The city said having two elevators will enhance convenience for residents and better prepare for safety accidents.

The city is in charge of assessing and permitting construction of buildings with 21 stories or higher or an architectural area of 100,000 square meters or larger.
