Delaware Rent Increase Law Overview
Understanding the legal framework in the First State
Delaware follows a market-based approach to rental housing. There is no statewide rent control, meaning landlords can set and raise rent to market rates with proper notice. While there is no state preemption, no local jurisdictions have enacted rent control.
✅ What This Means for Delaware Landlords
- No Rent Cap: You can raise rent to any amount the market will bear
- Notice Required: You must provide 60 days written notice before any increase
- No Frequency Limit: You can raise rent at any lease renewal (not during fixed-term leases)
- Market-Based: Rental rates are determined by supply and demand
While Delaware landlords have flexibility in setting rental rates, this freedom comes with responsibility. Rent increases must still comply with fair housing laws, cannot be retaliatory, and must be properly noticed. Professional landlords use this flexibility strategically, balancing market rates with tenant retention.

| Rent Control Status | No – Market Rate |
| Standard Notice Period | 60 days written notice |

Rent Increase Limits in Delaware
How much can you raise rent in the First State?
Delaware has no statewide rent cap. Landlords can raise rent to any amount, subject only to market conditions and proper notice requirements. There is no formula limiting increases, no percentage cap, and no approval process required.
💡 What “No Rent Control” Means in Practice
- You can raise rent by any dollar amount or percentage
- You can raise rent to match or exceed market rates
- You can raise rent at every lease renewal period
- You don’t need government approval for increases
- You still must provide proper written notice
- You still cannot discriminate or retaliate
While Delaware allows market-rate rent increases, smart landlords consider tenant retention when setting rates. Excessive increases may lead to vacancy, turnover costs, and the expense of finding new tenants. Balance market rates with the value of stable, long-term tenancies.
Notice Requirements
How much advance notice is required in Delaware?
Delaware law requires landlords to provide written notice before any rent increase takes effect. The notice must be delivered properly and give tenants adequate time to prepare for the new rental amount or make other housing decisions.
✅ Valid Notice Delivery Methods
- Personal delivery directly to the tenant
- Certified mail with return receipt requested
- First-class mail to tenant’s address (add extra days)
- Posting and mailing if personal delivery fails
Pro Tip: Always keep proof of service. For personal delivery, have the tenant sign acknowledging receipt. For mailed notices, retain the certified mail receipt.
❌ What Does NOT Count as Valid Notice
- Text messages or instant messages
- Emails (unless tenant agreed in writing to electronic notices)
- Verbal conversations or phone calls
- Voicemail messages
- Social media messages
- Notice posted only on common area bulletin board

Step-by-Step Compliance Guide
How to legally raise rent in Delaware
Review Your Lease Terms
Check your current lease agreement for any rent increase provisions. Fixed-term leases typically lock in rent until the lease ends. Month-to-month tenancies allow increases with proper notice.
Determine Your New Rent Amount
Research current market rates for comparable properties in your area. Consider factors like property condition, amenities, location, and tenant quality when setting your new rate.
Prepare Written Notice
Draft a clear rent increase notice including: current rent, new rent, dollar and percentage increase, effective date, and your signature. Keep a copy for your records.
Deliver Notice Properly
Serve the notice at least 60 days before the effective date using a valid delivery method. Personal delivery is best; if mailing, add extra days to account for delivery time.
Document Everything
Maintain records of the notice, proof of delivery, your calculations (if applicable), and any tenant communications. Keep these records for at least 3-4 years.
Update Rent Collection
After the notice period expires, update your rent roll, accounting systems, and payment portals. Begin collecting the new rent amount on the effective date.
Tenant Protections in Delaware
Rules that apply even without rent control
Even without rent control, Delaware tenant protections apply to all rent increases. Landlords must comply with these rules regardless of the amount of the increase.
✅ Landlords CAN
- Raise rent to market rate
- Raise rent at lease renewal
- Set different rents for different units
- Increase rent for improvements
- Adjust rent annually
❌ Landlords CANNOT
- Raise rent during a fixed-term lease
- Raise rent in retaliation for complaints
- Discriminate based on protected classes
- Raise rent without proper notice
- Use increases to force out tenants illegally
⚠️ Anti-Retaliation Protections
Delaware law prohibits landlords from raising rent in retaliation against tenants who:
- File complaints about habitability or code violations
- Exercise their legal rights under the lease
- Join or organize tenant associations
- Report the landlord to government agencies
A rent increase within a certain period after such protected activity may be presumed retaliatory, shifting the burden to the landlord to prove legitimate reasons.
⚠️ Avoid Costly Mistakes
Improper rent increases can lead to tenant disputes, legal challenges, and potential liability. Start with thorough tenant screening to find responsible renters.
