记住，美国每个州都有不同的法，俺州允许charge申请费，你州就不允许，进来仔细学习你州的法：

(b) At or prior to the commencement of any tenancy, no lessor may require a tenant or prospective tenant to pay any amount in excess of the following:

(i) rent for the first full month of occupancy; and,

(ii) rent for the last full month of occupancy calculated at the same rate as the first month; and,

(iii) a security deposit equal to the first month's rent provided that such security deposit is deposited as required by subsection (3) and that the tenant is given the statement of condition as required by subsection (2); and,

(iv) the purchase and installation cost for a key and lock.

这个和俺上面贴里提到的你麻州法律援助网说哪些收费是违法的解释是一致的，你打官司准输。

以上条文来自你州的有关法律：
