Realize that it's been a while since original post, but wanted to clarify info provided by brookdaleresident. ALSO, under current NJ law, landlords CANNOT withhold 1% admin fee!
Under NJ law, landlords have very specific obligations concerning tenant's security deposit. Here's a link which provides all info in pretty understandable terms:
http://www.ohiolandlordtenant.com/njsample.pdf
AMENDMENT TO LAW EFFECTIVE JAN 2004! CHECK YOUR FORM LEASES TO MAKE SURE THAT LANDLORD IS NOT USING OLD FORM WITH ILLEGAL PROVISIONS. Now, landlords must provide tenant with written notice within 30 days of receiving security deposit. This notice MUST contain all 5 items required under law (see link for specifics) and MUST be sent to tenant properly (ie, as required under lease). If not, then tenant can send written notice to landlord to apply entire deposit (plus applicable accrued interest) against rent. Landlord CANNOT contest this if cannot prove required notice sent properly.
Also, landlord MUST give similar written notice every year and pay accrued interest to tenant. If annual notice NOT given, then tenant can send written notice and landlord has 30 days to comply. SEE LINK FOR SPECIFICS.
Trust me, I recently dealt with this very issue and on principle, ended up taking it to court because the landlord kept trying to railroad me (I won and entire building benefited from it). Sadly, I'm sure that tenants will continue to have problems or be taken advantage of by landlords.
