Pennsylvania requires landlords to disclose details about the security deposit. Specifically, for deposits over $100, the landlord must deposit them in a federally or state-regulated institution, and give the tenant the name and address of the banking institution and the amount of the deposit. (68 Pa. Cons. Stat. Ann. §§ 250.511a to 250.512)
Check the Pennsylvania statute (68 Pa. Cons. Stat. Ann. §§ 250.511a to 250.512) for details on this disclosure. See the Laws and Legal Research section of Nolo for advice on finding and reading statutes and court decisions.
Also, check your local ordinance for any city or county disclosure requirements. To find yours, check your city or county website (many are listed on State and Local Government on the Net), or contact the office of your mayor, city manager, or county administrator.
Finally, see the Required Landlord Disclosures article for details on federally-required landlord disclosures and other information on disclosures about the rental property.
