Yokohama Disaster Prevention Power Improvement Condominium Certification System

Yokohama City certifies condominiums that are implementing disaster prevention measures as "Yokohama Disaster Prevention Power Improvement Condominiums" in order to plan the formation of condominiums that are resistant to disasters and the improvement of disaster prevention capabilities including surrounding areas.

Among condominiums that are implementing disaster prevention measures, condominiums that implement software measures such as disaster prevention activities are certified as "soft certification", and condominiums that are implementing measures for the entire building are certified as "hard certification". Condominiums that are linked with the community will be further certified as "soft + (plus) certification" and "hard + (plus) certification", respectively.

The details of the certification criteria.

You can see the apartments that have been certified in the past here.

　In recent years, heavy rain disasters have become more severe and frequent, and the possibility of flooding in our homes is increasing.However, for condominiums with a robust structure, measures to prevent flooding are implemented. By doing so, it is possible that you can continue living in the apartment without relying on evacuation centers.
　Therefore, as part of the Yokohama Disaster Prevention Improvement Condominium Certification System, we have created a “Inundation Countermeasures Guide” that summarizes procedures and specific methods for considering inundation countermeasures for condominiums. Make use of it when considering countermeasures against flooding.

This is a summary version of the guide for flood control.

This is the main part of the guide for flood control.

This is an introduction of a system that is useful for disaster prevention in condominiums. For more information, please contact each department in charge.
