Tenant demanding rent discount because PG&E has cut off power

[Carlos Lez]

With the recent storms in the Bay Area there have been a lot of power outages due to PG&E equipment failure. Some areas have been out of power for 4 days and counting. One of the resident's writes to us;

"You need to consider a credit or money refund for March rental payment. We have been without electrical power for four days.Your leasing company is receiving a very poor grade!"

Any thoughts on a fitting reply?

Act of god. Youre not responsible. If they have renters insurance, they can go to a hotel.
