Quick Reference: Delaware Repair Duties and Remedies at a Glance

Delaware's repair statute is generous to tenants in most respects and unusually restrictive in one.

The landlord's obligations under 25 Del. C. § 5305 are broad, the termination remedy in § 5306 can be exercised immediately where a unit is uninhabitable, and § 5308 lets a tenant withhold two thirds of the per diem rent when essential services fail for 48 hours.

But the repair-and-deduct remedy in § 5307 is capped at $400 or half of one month's rent, whichever is less. That is a low ceiling, and the word "less" does real work: on a $1,600 rent the cap is $400, not $800.

This guide covers the landlord's statutory duties, the principal repair-related remedies available to tenants, the conditions that switch each one off, and a lead-based paint obligation that is enacted but subject to deferred implementation.

The Landlord Duties Under § 5305

Section 5305(a) lists six landlord obligations, required at all times during the tenancy. The sixth, concerning lead-based paint certification, was added by 85 Del. Laws, c. 98 and is subject to that Act's deferred implementation provisions.

1. Comply with all applicable provisions of any state or local statute, code, regulation or ordinance governing the maintenance, construction, use or appearance of the rental unit and the property of which it is a part

2. Provide a rental unit which shall not endanger the health, welfare or safety of the tenants or occupants and which is fit for the purpose for which it is expressly rented

3. Keep in a clean and sanitary condition all common areas of the buildings, grounds, facilities and appurtenances maintained by the landlord

4. Make all repairs and arrangements necessary to put and keep the rental unit and its appurtenances in as good a condition as they were, or ought by law or agreement to have been, at the commencement of the tenancy

5. Maintain all electrical, plumbing and other facilities supplied by the landlord in good working order

6. Provide a rental unit free of lead-based paint hazards and certified as lead safe or lead free as required by Chapter 54

Duty 4 is the one to read closely. The benchmark is a compound: as good as the unit was at commencement, or as it ought by law or agreement to have been. A unit that was substandard at move-in does not set a low bar, because the second limb pulls the standard back up to what the law or the lease required.

Waste and utilities are conditional. Under § 5305(b), the landlord must provide waste receptacles and arrange frequent removal, and supply water, hot water, heat and electricity, only if the rental agreement so specifies. These are not free-standing statutory duties in Delaware; they follow the lease.

Code compliance is a shield. Under § 5305(d), evidence of compliance with the applicable building and housing codes is prima facie evidence that the landlord has complied with the chapter or any other chapter of Part III. That is a meaningful evidentiary advantage, and it makes inspection records worth keeping.

The Lead Certification Duty and Its Deferred Implementation

Duty 6 above needs an implementation qualifier, because its operation is deferred under § 5(2) of 85 Del. Laws, c. 98.

Section 5305(a)(6) was added by 85 Del. Laws, c. 98, and the section carries a bracketed note in the Code: for implementation of this section, see 85 Del. Laws, c. 98, § 5(2). The Delaware Code directs readers to that implementation provision rather than printing an operative date into the section itself.

The Act was enacted as House Substitute 2 for House Bill 70, as amended by House Amendment 1 and Senate Amendment 2, and signed on 21 July 2025. Its Section 5(2) provides that §§ 5402 to 5409, §§ 5411 to 5413, § 5305(a)(6) and § 5704A of Title 25 must be implemented on the earlier of two events, unless otherwise provided by a subsequent act of the General Assembly:

• Twelve months following publication in the Register of Regulations of a notice by the Director of the Delaware State Housing Authority that both (1) all necessary legislation and appropriations for implementation and enforcement of Chapter 54 have been enacted, and (2) final regulations implementing Chapter 54 have been promulgated; or

• 1 March 2028

The trigger is a published notice, so the operative date is not fixed in advance and can arrive before the backstop. The Act also requires annual Committee reports through 1 January 2030 under § 5410(g), and permits the Committee to propose new deadlines if it finds the existing ones infeasible.

Check whether the Housing Authority notice has been published before relying on any date.

The same Act added § 5704A, which will require a landlord filing a complaint for possession to provide documentation to the court showing compliance with Chapter 54. That provision is on the same implementation schedule.

What Chapter 54 will require. A property owner must obtain certification from a lead inspector that each rental unit constructed before 1 January 1978 is "lead free" or "lead safe," filed with the Department before commencement of a rental agreement with a new tenant, and no more than 4 years after the implementation date. The certificate must name the landlord and any property manager, the unit address, the inspector, the dates and the classification.

The obligations scale by portfolio size. A small property owner controls 19 or fewer rental units; a large property owner controls 20 or more. Under § 5402, a small owner faces a civil penalty of up to $100 per day per unit for failing to certify, and may certify a multi-unit building by having the inspector randomly select 5 units, with the rest deferred up to 4 years if all 5 are lead safe. Under § 5403, a large owner faces $500 per day for the first 30 days, $750 thereafter, and $1,000 after 60 days. Both provisions require the Department to give 30 days' notice and an opportunity to fix the violation before penalties begin.

Deferments and alternative housing. A deferment of up to 6 months is available where no approved inspectors or certified contractors are available, evidenced by contacting at least three, or where compliance is a significant economic burden. Where an inspection shows the unit is uninhabitable due to a lead hazard, the landlord must provide alternative housing with at least 10 days' advance notice before the tenant moves in or out. Section 5413 is an anti-loophole provision: units transferred to a spouse, child or parent count toward the transferor's total.

Two further duties attach at implementation. Under § 5406, every rental agreement on a pre-1978 unit must disclose the certification status, date and inspector, with the certificate supplied within 7 days of a request or a $50 per day penalty. Under § 5407, required educational material must be provided before occupancy, with a $20 per day penalty, and the agreement must require the tenant to acknowledge receipt.

For managers with pre-1978 Delaware properties, this is something to monitor and plan for now rather than a current certification obligation. Confirm the position with Delaware counsel before acting on it.

The Tenant Has a Reporting Duty Too

Delaware places an obligation on the other side as well, and it is easy to overlook in a chapter titled "landlord obligations."

Under 25 Del. C. § 5505(a), a tenant must put the landlord on notice, in writing and as soon as practicable, of any defective condition the tenant has reason to believe it is the duty of the landlord or of another tenant to repair. A tenant who fails to report is responsible for any liability or injury resulting to the landlord. The requirement does not apply where the landlord already has actual notice of the condition.

That matters operationally in two ways. It gives a landlord a genuine answer where a condition worsened silently, and it makes the date a report arrived the pivot for most of the remedies below. Both point the same way: log incoming reports with a timestamp and keep the record of what the tenant actually said.

Shifting Repairs to the Tenant

Section 5305(c) permits an agreement that the tenant performs specified repairs, maintenance, alterations or remodelling, but the conditions are strict. The agreement must be by a conspicuous writing, separate from the rental agreement, and all four of the following must hold:

1. The particular work is for the primary benefit of the rental unit

2. The work is not necessary to bring a noncomplying unit into compliance with a building or housing code or the like

3. Adequate consideration apart from the rental agreement, or a reduction in rent, is exchanged for the tenant's promise, and the landlord may not treat any such agreement as a condition to any provision of the rental agreement

4. The agreement is entered into in good faith and not for the purpose of evading an obligation of the landlord

Condition 2 is the limiting one. Code compliance work cannot be transferred at all. Condition 3 means the arrangement has to be paid for, in money or rent reduction, and cannot be made a precondition of the tenancy.

Route One: Repair and Deduct Under § 5307

This is the remedy with the tightest cap and the most interesting trigger.

Two triggers, not one. After written notice from the tenant, the tenant may proceed if the landlord either:

• (1) fails to remedy the failure within 30 days of receipt of the notice; or

• (2) fails to initiate reasonable corrective measures where appropriate, including but not limited to obtaining an estimate of the prospective costs of correction, within 10 days of receipt

The second trigger is the one managers most often miss. A landlord who does nothing for eleven days has exposed the unit to self-help even though the thirty days has not run. Obtaining an estimate is expressly listed as one example of a reasonable corrective measure; the statute does not make an estimate the only qualifying response.

The two triggers operate separately. The tenant may proceed if the landlord fails either to initiate reasonable corrective measures within 10 days or to remedy the failure within 30 days. A landlord can therefore act within 10 days and still legitimately need the full 30 to complete the work.

An operational note. Log the date a repair notice is received and the date an estimate or vendor contact is initiated. The 10-day clock runs from receipt, and the record of what you initiated is the answer to a premature deduction.

The cap. Once triggered, the tenant may do or have the necessary work done in a professional manner, then deduct from rent a reasonable sum not exceeding $400, or one half of one month's rent, whichever is less, by submitting copies of receipts covering at least the sum deducted.

Note the direction of "whichever is less." At rents above $800 a month, the $400 figure controls. At rents below $800, half the rent controls. The ceiling only rises with rent up to $800.

Three limits. Under (b), the remedy is unavailable where the condition was caused by the want of due care by the tenant, a family member or another person on the premises with the tenant's consent. Under (c), a tenant otherwise delinquent in the payment of rent may not use this section at all. Under (d), the tenant is liable for damage to persons or property caused by the tenant or someone authorised by the tenant in making the repairs.

Subsection (c) is worth building into your response process: a tenant who is otherwise delinquent in the payment of rent cannot use the § 5307 remedy, so the ledger position at the time of the deduction matters.

Route Two: Termination Under § 5306

Where a condition deprives the tenant of a substantial part of the benefit or enjoyment of the tenant's bargain, the tenant may notify the landlord in writing, and if the landlord does not remedy within 15 days following receipt of notice, the tenant may terminate.

And there is an immediate route. If the condition renders the premises uninhabitable or poses an imminent threat to the health, safety or welfare of the tenant or any family member, the tenant may, after giving notice, immediately terminate without proceeding in a Justice of the Peace Court.

That is the provision that turns a serious habitability failure into a same-day loss of the tenancy. There is no cure period and no court step.

Damages where the landlord is at fault. Under § 5306(c), if the condition was caused wilfully or negligently by the landlord, the tenant may recover the greater of:

• the difference between rent payable under the agreement and all expenses necessary to obtain equivalent substitute housing for the remainder of the rental term; or

• an amount equal to one month's rent and the security deposit

The limit. Under (b), the tenant may not terminate for a condition caused by the want of due care by the tenant, a family member or a person on the premises with the tenant's consent, and a tenant who terminates wrongfully remains obligated under the agreement.

A parallel early-tenancy route. Section 5302 gives a separate remedy in the first month of occupancy where the landlord fails to substantially conform to the agreement or there is material noncompliance with a code, plus a repeat-breach provision: where substantially the same act or omission recurs within 6 months of a prior noticed noncompliance, the tenant may terminate on at least 15 days' written notice.

Route Three: Essential Services Under § 5308

Delaware treats loss of hot water, heat, water or electricity as its own category, with a short fuse.

The trigger is 48 hours. Where the landlord substantially fails to provide hot water, heat, water or electricity, or fails to remedy any condition which materially deprives the tenant of a substantial part of the benefit of the bargain in violation of the agreement, the Code, or an applicable housing code, and the failure continues for 48 hours or more after the tenant gives actual or written notice, the tenant may:

• immediately terminate the rental agreement on written notice of the continuation; or

• keep two thirds of the per diem rent accruing during any period when the service or equivalent substitute housing is not supplied

Impossibility is a defence. The statute expressly allows the landlord to avoid the withholding liability by a showing of impossibility of performance.

If the tenant stays and the failure continues, subsection (b) adds a third option: on notice, the tenant may procure equivalent substitute housing for as long as the service is not supplied, during which rent abates and the landlord is liable for additional expense up to one half of the amount of abated rent, again subject to impossibility. Under (c), withholding does not bar subsequent recovery of damages exceeding the amount withheld.

And a tenant who withholds wrongly faces a penalty. Under (d), where a landlord files for summary possession claiming the tenant wrongfully withheld or deducted, and the court so finds, the landlord is entitled to possession or the amount wrongfully withheld, or double that amount if the court finds the tenant acted in bad faith. The court orders payment within 10 days, and if it is not paid, the judgment becomes one for the amount withheld plus summary possession, without further notice.

Route Four: Fire and Casualty Under § 5309

Where fire or casualty substantially impairs enjoyment of the unit without tenant fault, the tenant may immediately quit and notify the landlord in writing within one week after vacating, terminating as of the vacating date; or, if continued occupancy is lawful, vacate the unusable part and reduce rent in proportion to the loss in fair rental value.

Failure to give timely notice leaves the tenant liable for rent until the landlord actually learns of the vacating. On termination the landlord must timely return the security deposit, pet deposit and prepaid rent, accounted as of the date of the casualty.

Bed Bugs: A Separate Clock

Section 5317 sets hour-based deadlines outside the general repair framework.

Before renting, the owner or property manager must visually inspect the unit, must not show, rent or lease a vacant unit known or reasonably suspected to be infested, and must disclose whether an adjacent unit is currently infested or being treated.

On notification, the landlord must acknowledge and inspect within 120 hours, provide remedial services within 14 days on determining an infestation, and inspect units directly adjacent to, above or below within 5 days. The landlord must give notice under § 5509 before entering, share the professional's determination within 120 hours of receiving it, and keep written records for 2 years.

Cost allocation turns on two windows. The landlord bears the cost where the tenant reports within 60 days after occupancy, or within 30 days of a discovery in an adjoining unit. Outside those windows the landlord still investigates and remediates, but the tenant shares in the reasonable costs for their own unit, except in properties managed by a state or local government housing authority.

Lease Terms Delaware Forbids

Under § 5301(a), a rental agreement may not provide that a tenant:

1. Agrees to waive or forego rights or remedies under the Code

2. Authorises any person to confess judgment on a claim arising out of the agreement

3. Agrees to the exculpation or limitation of any liability of the landlord arising under law, or to indemnify the landlord for that liability or associated costs

4. Must declaw a cat as a condition of the agreement

Under subsection (b), a prohibited provision is unenforceable, and if a landlord attempts to enforce a provision known to be prohibited, the tenant may recover an amount equal to 3 months' rent plus costs, excluding attorney's fees. That exposure attaches to attempted enforcement rather than inclusion, which makes staff instruction as important as the template audit.

Two related prohibitions. Under § 5310, a landlord may not ask for or receive "assurance money," nor charge more than the specific cost of a credit or other investigation. Under § 5311, apart from optional service fees for actual services such as a pool or tennis court, a landlord shall not charge any nonrefundable fee as a condition for occupancy.

And self-help carries treble damages. Under § 5313, a tenant removed or excluded except under colour of a valid court order may recover possession or terminate, and may recover treble the damages sustained or three times the per diem rent for the exclusion period, whichever is greater, plus costs.

Common Delaware Compliance Mistakes

1. Diarying 30 days on a repair notice. Section 5307(a)(2) lets a tenant proceed if reasonable corrective measures are not initiated within 10 days.

2. Reading the repair-and-deduct cap as half a month's rent. It is $400 or half a month's rent, whichever is less.

3. Missing that arrears switch the remedy off. Under § 5307(c) a tenant delinquent in rent cannot use repair and deduct.

4. Assuming a cure period always applies to termination. Under § 5306(a) an uninhabitable unit or imminent threat allows immediate termination without a court step.

5. Treating the 48-hour essential services clock as calendar days. It runs in hours from actual or written notice.

6. Overlooking the impossibility defence. Section 5308 expressly allows it against the withholding liability.

7. Shifting code compliance work to a tenant. Section 5305(c)(2) prohibits it outright.

8. Putting a maintenance agreement inside the lease. Section 5305(c) requires a conspicuous writing separate from the rental agreement, with separate consideration.

9. Missing the bed bug hours. Acknowledge and inspect within 120 hours, remediate within 14 days, adjacent units within 5 days.

10. Charging a nonrefundable fee. Section 5311 prohibits it as a condition of occupancy, apart from optional service fees.

11. Attempting to enforce a prohibited lease clause. Section 5301(b) exposes the landlord to three months' rent plus costs.

12. Assuming the lead certification duty is live. Section 5305(a)(6) and § 5704A carry an implementation note deferring enforcement under § 5(2) of 85 Del. Laws, c. 98.

13. Overlooking the tenant's own duty. Under § 5505(a) a tenant must report a defective condition in writing as soon as practicable, unless the landlord already has actual notice.

14. Assuming the lead penalties are uniform. They scale by portfolio size: up to $100 per day per unit for a small owner, rising to $1,000 per day for a large owner after 60 days.

15. Splitting a portfolio to stay under 20 units. Section 5413 counts units transferred to a spouse, child or parent toward the transferor.

What the Record Has to Show

Delaware's repair provisions turn on dates measured in days and hours, and on one evidentiary advantage the landlord has to earn.

• Section 5305(d) is the one worth designing around. Evidence of compliance with applicable building and housing codes is prima facie evidence of compliance with the chapter. That means inspection certificates, permits and code correspondence are not filing clutter; they shift the evidential position.

• The ten-day clock runs first. Because § 5307(a)(2) turns on initiating reasonable corrective measures, the record that matters most is often the earliest one: the date the notice arrived and the date an estimate was sought.

• Section 5505 makes the incoming report itself evidence. A tenant's written notice starts the clocks, and its absence is a defence where the landlord had no actual notice. Capturing what was reported and when is therefore useful in both directions.

• Some duties run on hours rather than days. The essential services rule uses 48 hours, while the bed bug provisions use 120-hour and 5-day deadlines. Both require timestamps rather than dates.

Conclusion

Delaware gives tenants four distinct routes when a landlord fails to repair, and each has its own clock.

Repair and deduct runs on 10 days to initiate corrective measures or 30 days to remedy, capped at $400 or half a month's rent, whichever is less, and unavailable to a tenant in arrears. Termination runs on 15 days, or immediately where the unit is uninhabitable or poses an imminent threat. Essential services run on 48 hours, unlocking two thirds per diem withholding or substitute housing. Fire and casualty allows the tenant to quit with notice within one week of vacating.

Against that, the landlord has one significant advantage: under § 5305(d), documented code compliance is prima facie evidence of compliance with the chapter.

For managers in Wilmington, Dover, Newark, Middletown and Smyrna, the operating discipline is short. Timestamp every repair notice on arrival. Initiate something visible, an estimate at minimum, inside ten days. Keep code and inspection records where they can be produced. Move any tenant maintenance arrangement out of the lease into a separate, paid-for writing. Treat essential services and bed bug reports as hour-clock events. And monitor the implementation of the new lead certification requirements for pre-1978 stock, because the enacted provisions include both certification and possession-filing requirements that will take effect under the schedule in § 5(2).

Frequently Asked Questions

Q1. What repairs is a Delaware landlord required to make?
Section 5305(a) requires compliance with applicable codes, a unit that does not endanger health, welfare or safety and is fit for its purpose, clean common areas, repairs keeping the unit as good as at commencement or as it ought by law to have been, and facilities supplied by the landlord in good working order.

Q2. How much can a Delaware tenant deduct for repairs?
A reasonable sum not exceeding $400 or one half of one month's rent, whichever is less, under § 5307(a), on submitting receipts covering at least the sum deducted.

Q3. How long does a Delaware landlord have to respond to a repair notice?
Two periods run at once. Under § 5307(a)(2) the landlord must initiate reasonable corrective measures, such as obtaining an estimate, within 10 days. Under § 5307(a)(1) the failure must be remedied within 30 days.

Q4. Can a Delaware tenant in arrears use repair and deduct?
No. Section 5307(c) provides that a tenant otherwise delinquent in the payment of rent may not take advantage of the remedy.

Q5. When can a Delaware tenant terminate for a repair problem?
After 15 days following written notice of a condition depriving them of a substantial part of the benefit of the bargain, under § 5306(a). Where the condition renders the premises uninhabitable or poses an imminent threat, the tenant may terminate immediately without going to court.

Q6. What happens if heat or hot water fails in Delaware?
Under § 5308, if the failure continues 48 hours or more after notice, the tenant may terminate or withhold two thirds of the per diem rent, and may procure substitute housing if the failure continues. The landlord may raise impossibility of performance.

Q7. Can a Delaware lease make the tenant responsible for repairs?
Only under § 5305(c), by a conspicuous writing separate from the lease, for work primarily benefiting the unit, not needed for code compliance, supported by separate consideration or a rent reduction, entered into in good faith, and never as a condition of the rental agreement.

Q8. What are the bed bug deadlines in Delaware?
Under § 5317(d), acknowledge within 120 hours, inspect or obtain investigatory services within 120 hours, provide remedial services within 14 days of notification, and inspect adjacent units within 5 days. Records must be kept for 2 years.

Q9. Is the Delaware lead certification requirement in force?
Section 5305(a)(6) and § 5704A were enacted by 85 Del. Laws, c. 98. Their implementation is deferred under § 5(2) of that Act and occurs on the earlier of 12 months after the specified Delaware State Housing Authority notice is published in the Register of Regulations, or 1 March 2028, unless changed by a subsequent act. Confirm the current implementation status before relying on the requirements.

Q10. Does a Delaware tenant have to report repair problems?
Yes. Under § 5505(a) a tenant must notify the landlord in writing, as soon as practicable, of any defective condition the tenant has reason to believe the landlord or another tenant must repair, and may be responsible for resulting liability or injury if they do not. The duty does not apply where the landlord already has actual notice.

Q11. What if a Delaware landlord locks a tenant out?
Under § 5313, a tenant removed or excluded other than under colour of a valid court order may recover possession or terminate, and may recover treble damages or three times the per diem rent for the exclusion period, whichever is greater, plus costs.
