Delaware Residential Rent Increase Notice

Use this notice for renewal of a fixed-term rental agreement with an increased rent. Confirm that the agreement and any controlling subsidy or other housing rules permit this renewal route.

Delaware Renewal-With-Increase Module

When a landlord intends to renew a rental agreement with modified provisions, including a different rent, the landlord must give at least 60 days' written notice before the agreement expires. The notice must specify the amended provisions, rent, and effective date. After receiving that notice, a tenant who intends to terminate must notify the landlord at least 45 days before the term ends to avoid deemed acceptance of the modified agreement. Rejection of the modified terms is treated as a termination notice. Outside this modified-renewal procedure, § 5106(c) generally requires a tenant's written termination notice at least 60 days before a fixed term expires. The § 5107(a)-(c) procedure does not apply when rent and security deposit depend on tenant income under HUD regulations or guidelines; those HUD rules govern adjustments. 25 Del. C. §§ 5106(c), 5107(a)-(d). Serve by a method allowed by § 5113.

Landlord-tenant paperwork governs who can stay in a property, on what terms, and what happens when something goes wrong. Leases, notices to quit, security deposit demands, and habitability complaints all have state and often city-specific requirements for timing, content, and service. Getting the paperwork right is what makes an eviction actually succeed or a security deposit actually come back, because judges regularly dismiss cases over small procedural mistakes.
