Why would you have a problem giving the address? It can come in useful. We had a situation recently when a colleague went missing and noone could contact them and they ended up sending someone round to check if they were ok.
Similarly there were two incidents in my street in the space of a year where people were reported missing, at least one by their work, leading to the police turning up, breaking in and both were found dead.
It doesn't seem an unreasonable request to know where you live on a daily basis when at work.
