Delaware Rent Increase Rules

Delaware allows landlords to charge market rates and makes provisions for rent increases when leases are renewed. However, landlords must strictly abide by specific notice periods outlined in Title 25 before implementing any changes in rent.

Is There Rent Control in Delaware?

No. The State of Delaware does not have rent control policies, nor are municipalities allowed to enact strict rent control preempting state law for private residential dwellings. Therefore, there is no statutory limit or strict percentage cap on how much a landlord can increase the rent.

A landlord may raise the rent to whatever the market will bear, provided they give the proper notice required by law and the increase is not retaliatory or discriminatory.

Notice Periods for Rent Increases

1. Fixed-Term Leases

During an active fixed-term lease (such as a 1-year agreement), a landlord cannot raise the rent unless the lease agreement explicitly includes a legally binding provision allowing for a mid-lease increase (which is uncommon and highly discouraged in residential leasing).

For Lease Renewals: Before the lease expires, if the landlord wishes to offer a renewal at a higher rental rate, the landlord must provide the tenant with written notice at least 60 days before the expiration of the lease term (Title 25 § 5107).

• If the landlord gives the 60-day notice of a rent increase, the tenant then has 15 days to reject the new terms from the date they receive it.
• If the tenant does not reject the terms within 15 days, the new rental agreement (and higher rent) goes into effect at the end of the current term.
• If the tenant rejects the terms, the tenancy terminates at the end of the original lease, and the tenant must move out.

2. Month-to-Month Tenancies

For a month-to-month tenancy, the landlord must provide at least 60 days' written notice prior to the date on which the rent increase will take effect.

The 60 days must run from the beginning of a rental period. For example, if rent is due on the 1st of the month, and notice is given on July 15th, the new rent will not apply to August, but to the rental period beginning October 1st (as the 60-day period covers August and September).

Retaliatory Rent Increases Prohibited

Under Title 25, landlords cannot raise the rent as an act of retaliation against a tenant.

A rent increase is presumed retaliatory if the landlord issues the notice within 90 days after the tenant has:

• Complained in good faith to a government agency about housing code violations.
• Complained to the landlord in writing about habitability or repair issues.
• Organized or joined a tenant's union or similar organization.
• Pursued legal rights granted under the state Landlord-Tenant Code.

If a tenant successfully proves a rent increase is retaliatory in court, the landlord may be forced to pay damages equal to three months' rent, plus court costs.

Best Practices for Delaware Landlords

1. Track Expiration Dates: With a 60-day notice requirement for renewals, landlords must begin preparing renewal offers at least 90 days before a lease expires to give themselves time to calculate market rates and draft the notice.
2. Serve Notice Formally: Send rent increase notices via certified mail to have a trackable record, or hand-deliver them with a witness to prove the 60-day deadline was met.
3. Be Reasonable: While there's no legal cap, exorbitant rent increases often lead to tenant turnover, costing you more in vacancy periods and turnover repairs than you gained from the rent hike.
