Building "lease fee"

[Margharita Silva]

Hi everyone, 

My building (condo high rise) started implementing a fee called "lease fee" two years ago. Its $500 per year. 

They passed the resolution. Can this challenged or negotiated in some way? 

I own one apartment (vs some "investors" who own multiple units in the bldg ) and have the same (great) tenant since before this resolution. They want to charge this fee every time the lease renews not every time I have a new tenant. I feel it's a bit unfair and frankly I am not going to charge the tenant anymore than what the place is worth market rate because of its location and he is a great tenant (pays on time, keeps the place clean, communicative etc) I feel like i should even give him a break because he said he couldn't even be home since there was construction all summer due to building maintenance repairs. 

Thanks.
