Delaware Rent Increase 2026: 60-Day Renewal Notice & Manufactured-Home Rules
Delaware's ordinary residential code requires at least 60 days' written notice before a rental agreement expires when a landlord renews it with modified rent or other terms. Manufactured-home communities use a separate 90–120 day notice and once-per-12-month framework. Learn which rule applies before serving or relying on an increase.
The short answer
For an ordinary Delaware residential rental, 25 Del. C. § 5107 requires a landlord who intends to renew a rental agreement with amended or modified provisions—including a change in rent—to give the tenant at least 60 days' written notice before the existing agreement expires. The notice must identify the changed provisions, the amount of rent or security deposit, and the date the changes take effect.
That 60-day renewal rule should not be flattened into a claim that every Delaware housing arrangement follows the same path. HUD-subsidized housing can be governed by federal requirements, and manufactured-home community lot rent follows a separate Delaware framework with 90–120 days' notice, a once-per-12-month limit, and DEMHRA rent-justification rules.
Section 5107 ties the 60-day rule to a renewal with modified terms
The ordinary residential rule is written as a renewal-with-modifications statute. If the landlord intends to renew the rental agreement with changed provisions, including the amount of rent, the landlord must give a minimum of 60 days' written notice before expiration of the current agreement. The notice must state what is changing, the rent or security-deposit amount, and the effective date.
After receiving a § 5107 notice, the tenant generally must notify the landlord of an intention to terminate at least 45 days before the final day of the existing term if the tenant does not want the modified renewal. If the tenant rejects the modified terms, the rejected renewal notice is treated as an effective termination notice under the statute. Those response mechanics are part of why the actual lease-end date matters.
Do not confuse renewal notice with Delaware's termination rules
Section 5106 separately governs termination. A landlord or tenant terminating an ordinary fixed-term rental agreement generally gives at least 60 days' written notice before expiration. For a month-to-month agreement, the statute also uses a 60-day written-notice period, but says that period begins on the first day of the month following the day of actual notice.
Those termination provisions are related to the tenancy timeline, but they are not a substitute for § 5107's rent-renewal requirements. A rent increase notice should be planned around the actual agreement, expiration or renewal structure, and the legal path being used rather than assuming every 60-day rule is interchangeable.
A fixed-term lease still needs a lease-first review
Section 5107 is about the next agreement or renewed terms. It should not be read as automatic permission to rewrite rent in the middle of an existing fixed term. Before proposing an increase, identify the current term, expiration date, any renewal clause, the proposed effective date, and whether the lease itself contains a lawful rent-adjustment mechanism.
Section 5108 also matters when a rental agreement of one year or more reaches the end of its term without timely termination or a renewal-with-modifications notice: the tenancy can convert to month-to-month while the other agreement terms continue. If a § 5107 modification notice was sent, § 5107 controls that modified renewal path.
HUD-subsidized rent can follow federal rules instead
Delaware's ordinary code expressly preserves federal control where a federally subsidized tenancy conflicts with state timing. Section 5107 also says its ordinary renewal-with-modifications process does not apply when rent and the security deposit are a function of tenant income under HUD regulations or guidelines; the applicable HUD rules govern those adjustments.
Do not apply the ordinary 60-day renewal answer to a subsidized unit without checking the housing program, assistance contract, required notices, and current federal guidance. Max Rental Tools treats the state rule as a starting point, not a replacement for program-specific requirements.
Manufactured-home community lot rent uses a separate 90–120 day framework
Delaware's Manufactured Home Owners and Community Owners Act uses a separate process. Under 25 Del. C. § 7051, a community owner may not increase a tenant's lot rent more than once during any 12-month period and must provide written notice at least 90 days, but no more than 120 days, before the first day the increased rent is due. Notice goes to affected homeowners, the homeowners' association if one exists, and DEMHRA.
The manufactured-home framework also requires the increase to comply with the lease and the applicable statutory rent-justification provisions. It should not be replaced with the ordinary § 5107 renewal rule merely because both concern residential housing.
What Delaware's current DEMHRA CPI-U number means
DEMHRA currently reports that, as of July 14, 2026, the 24-month CPI-U is 4.357%. Its published page calculates 5.678% for the CPI-U-based base-increase path under § 7052A when the CPI-U is at or below 6.1%.
That 5.678% figure is not a universal Delaware residential rent cap and should not be applied to apartments, single-family rentals, condos, rooms, or other ordinary rentals. Even within manufactured-home communities, § 7052A contains different statutory paths, including market-rent and additional justified-expense mechanisms. Recheck DEMHRA's current CPI-U page and the statute before relying on a percentage because the published input can change.
Example: identify the legal path before counting days
Suppose a landlord wants to offer a Delaware tenant a renewal at a higher rent. Start with the current agreement's expiration date and confirm that the proposal is a renewal with modified terms. Then count the § 5107 notice period backward from that expiration date, preserve the actual service record, and make sure the notice states the changed rent and effective date.
If the property is a manufactured-home community lot, stop and use the separate 90–120 day framework instead. If the tenancy is HUD-subsidized or another specialized housing program applies, review that program before relying on the ordinary state timeline.
Use Max Rental Tools after confirming the Delaware pathway
Use the Delaware state guide and rent-increase calculator to measure the proposed change and organize the tenancy dates. For an ordinary renewal with modified rent, the current statewide starting point is § 5107's minimum 60-day written notice before expiration, while the lease and any special housing rules still need review.
When the facts are confirmed, use the Rent Increase Notice, Lease Renewal Notice, Month-to-Month Rental Agreement, or Rent Ledger workflow that matches the actual relationship. For a manufactured-home community, use the Delaware Code, DEMHRA, and Department of Justice sources below rather than substituting an ordinary apartment notice rule.
Common questions
How much notice does a Delaware landlord need to raise rent at renewal in 2026?
For an ordinary residential rental renewed with modified terms, including rent, 25 Del. C. § 5107 requires at least 60 days' written notice before the existing rental agreement expires, subject to the statute's HUD-related exceptions and other applicable requirements.
Does Delaware have one statewide percentage cap for ordinary private residential rent increases?
The ordinary § 5107 renewal framework reviewed here governs notice and modified lease terms rather than setting one statewide percentage formula for ordinary private-market rentals. Lease terms and specialized housing rules still matter.
Can a Delaware landlord raise rent in the middle of a fixed-term lease?
Section 5107 governs renewal with modified terms; it does not by itself authorize a mid-term rewrite of the rent promised in an existing fixed-term agreement. Review the signed lease and current law before treating a mid-term increase as permitted.
What happens if a Delaware tenant rejects a renewal with higher rent?
Under § 5107, a tenant generally must give notice of an intention to terminate at least 45 days before the last day of the existing term to reject the modified renewal, and a rejected renewal notice is treated as an effective termination notice under the statute.
How much notice is required for a Delaware manufactured-home community lot-rent increase?
Section 7051 requires written notice at least 90 days and no more than 120 days before the first increased lot-rent payment is due, and it limits lot-rent increases to no more than once during any 12-month period.
Is 5.678% the Delaware manufactured-home rent cap for every increase in 2026?
No. DEMHRA's July 14, 2026 page calculates 5.678% for the current CPI-U-based base-increase path. The manufactured-home statute also contains other rent-justification paths, so the current statute and DEMHRA guidance must be checked for the proposed increase.
