I know that link and it helps

however, I was thinking more of this http://search.municode.com/html/16093/index.html which says there apparently is a allowable rent increase limit, I just wasn't sure if my building would fit into that category or if there was a way to find out?

and no, i didn't say i am paying $4,000 a month for rent

I just got the lease renewal letter and my rent is going up 20%, or about $362 a month ($4,344 annually) should I renew.

I've also written a letter to leasing office expressing my objection to the increase as being too high and unfair and asked for a more reasonable increase to no avail. The response was that the market conditions are different now, and units similar to mine are renting for as much as 35% more (though a lot of current residents are paying what I am paying now since they are not up for renewal). My argument was that this is for new tenants and not existing, so the percentage increase does not apply to them as it does for me.

My question: is the property manager's argument valid can my rent be increased simply because the landlord wants to make a bigger profit based on what the units are renting for now or is this worth fighting?

How can I find out if my building (The Pier, Harborside Place) is rent controlled or if the increase is allowed?
