The main Delaware lease disclosures

Landlord-Tenant Code Summary (25 Del. C. § 5118): the landlord must give a new tenant the state Summary of the Landlord-Tenant Code; if it isn't provided, the tenant may plead ignorance of the Code as a defense.

Federal lead-based paint disclosure

Whatever Delaware requires, the federal lead rule stands on top. For a home built before 1978 the landlord must, under Title X (42 U.S.C. § 4852d), provide a signed lead-warning disclosure, disclose known lead hazards, turn over available records, and give the tenant the EPA pamphlet Protect Your Family From Lead in Your Home — with civil and potentially criminal penalties for failing to.

What happens if a Delaware landlord skips a required disclosure?

Consequences depend on the disclosure:

  • Missing the Code Summary lets the tenant plead ignorance of the Code as a defense (§ 5118).
  • A missed 20-day deposit return exposes the landlord to the wrongfully withheld amount and possible double damages (§ 5514).
  • A federal lead-paint violation carries civil and, in egregious cases, criminal penalties plus liability for tenant damages.
