The District of Columbia requires landlords to make the following disclosures to tenants, usually in writing and at the start of the tenancy:
At the start of every new tenancy, landlord must give tenant a copy of the District of Columbia Municipal Regulations, CDCR Title 14, Housing, Chapter 3, Landlord and Tenant; and a copy of Title 14, Housing, Chapter 1, § 101 (Civil Enforcement Policy) and Chapter 1, § 106 (Notification of Tenants Concerning Violations).
See the Laws and Legal Research section of Nolo for advice on finding and reading statutes and court decisions.
Also, check your local ordinance, particularly if your rental unit is covered by rent control, 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.
