Delaware sets no cap on rent and has no mid-term rent-increase statute. A rent change runs through the renewal mechanism of the Landlord-Tenant Code, which requires at least 60 days' written notice before a term expires for any amended terms, including rent (Del. Code tit. 25 § 5107).
Delaware does not regulate the amount of residential rent or impose rent control. To change rent, a landlord uses the renewal mechanism in Del. Code tit. 25 § 5107: the landlord must give the tenant 'a minimum of 60 days' written notice prior to the expiration of the rental agreement' that it will be renewed with amended provisions, including the amount of rent. For a month-to-month tenancy, that 60-day notice tracks the § 5106 termination period and the 60-day window begins the first day of the month following actual notice. During a fixed-term lease, rent cannot be raised mid-term unless the lease allows it. A tenant who objects at least 45 days before the term ends rejects the change, and the notice then operates as a termination.
No specific statutory penalty. A rent increase served with less than the required 60-day notice is not effective; the prior rent remains the enforceable amount until a proper notice period runs.
