Holiday tipping to building staff?

No one will ever tell you b/c no one wants to seem cheap. If you just moved in, you don't need to give everyone $50.
Give a nice tip to your super and the doormen you interact with the most, less to everyone else. I think $50 for the high end is fair; you could probably give less given the situation, too.

Nothing, If you just moved in, not that much is expected from you. In most cases for the type of building you describe, there is a collection box where you can give collective tip. I would think $200-500 (could be $500 to $1000+ if you lived there full year) is fine depending on the size of the apartment. If you have someone who has been very helpful, give them an additional $50-$100. Also, depends on the service you want. If you want extras as in getting you cabs etc, helping with your children and groceries, I would tip more.

You do not have to give a lot if you just moved it--the tip is really a thank you for service over the past year.

Perhaps; but when you move in late odds are that the prior owner/tenant didn't tip before they left. I tend to err on being generous with tipping as they are often a big part of compensatio

eriegel, that's not the new tenant's problem. it's up to each person.
when i previously moved in november, I went back to my old building and dropped off mostly full-year tips for those employees and then gave token tips ($20 each) to my new building staff. Then at the end of the next year they got full tips.

Agreed. We had purchased a condo; were there about 4 1/2 moths and just felt that we should establish a good working relationship. The previous owners moved to California

If you moved in the past 3 months, tip 50%. If you moved any before that, 100%. Tipping the year ahead will do wonders for your relationships with building staff and make your next year better.
