How can building access and security be maintained?
Any landlords or building managers have experience with solving  building access issues?

Currently a multi-story mixed office building with an unlocked lobby during standard business hours M-F. Tenants have 24/7 access when the lobby is locked via a key card.

Looking to add a full floor fitness tenant who would need extended building access evenings and weekends. It may be impractical for them to give all of their clients keycards, and that is less than ideal since they would then have access to the full building when most other businesses in the building are closed.

The elevator can be locked by floor with a physical key, but there is only one master key for the elevator, so if all the other floors were locked after hours, tenants would not have elevator access to the space. All floors are currently left unlocked.

Anybody have suggestions for using the current system or upgrading the system in a way that solves this problem?

Thanks!

Moreover, getting a handful of cameras and a dedicated DVR is inexpensive.\n\nI hope this helps ", "replies": [{"id": "c52nxpi", "text": "Good advice. The building already has cameras, more a question of limiting access to those who need it.", "replies": [], "depth": 2}], "depth": 1}]
