Delaware’s rental market in 2025 remains largely unregulated when it comes to rent control, but there are important legal protections and procedures that tenants should understand. Here’s a detailed guide to help Delaware renters navigate potential rent increases.
No Statewide Rent Control
Delaware does not have any statewide or local rent control laws that cap the amount a landlord can raise rent. This means landlords are generally free to set rent prices and determine increases based on market conditions, as long as they follow the state’s notice requirements and do not act in a discriminatory or retaliatory manner.
Notice Requirements for Rent Increases
Standard Rental Properties
- For rent increases of less than 20%: Landlords must provide at least 30 days’ written notice before the increase takes effect.
- For rent increases of 20% or more: A 60 days’ written notice is required.
- For most other situations: Many sources recommend a 60-day notice as standard practice, especially for month-to-month leases or at the end of a fixed-term lease.
Manufactured/Mobile Home Communities
- Landlords must provide a 90-day written notice for any rent increase.
- Tenants in these communities have additional protections, including the right to challenge excessive increases through a rent justification process.
During a Lease Term
- Rent cannot be increased during an active lease term unless the lease agreement specifically allows for it.
- Any attempt to raise rent mid-lease without such a clause is considered invalid.
Frequency and Limits on Rent Increases
- Delaware law does not limit how often a landlord can raise rent. There are no restrictions preventing multiple increases in a single year, provided each increase is accompanied by proper notice.
- There are no statutory caps on the percentage or dollar amount of a rent increase for standard residential properties.
Tenant Rights and Protections
Right to Notice and Response
- Tenants must receive written notice directly; verbal notice or posting in common areas is not sufficient.
- If a tenant objects to a rent increase, they typically must respond within 45 days of receiving notice, especially if they wish to negotiate or contest the increase.
Protection Against Retaliation and Discrimination
- Landlords cannot increase rent as retaliation for tenants asserting their legal rights (such as requesting repairs or filing complaints).
- Rent increases cannot be based on discriminatory reasons, including race, gender, disability, familial status, or other protected characteristics under the Fair Housing Act.
Right to Habitable Living Conditions
- Tenants are entitled to safe, habitable housing. If a landlord fails to maintain the property, tenants may have the right to withhold rent or terminate the lease after following proper procedures.
Security Deposits
- Security deposits are capped at one month’s rent and must be returned within 20 days of move-out, minus any legitimate deductions.
Special Considerations
Mobile Home Tenants
- Additional protections apply, including a longer notice period and the right to challenge increases through a formal process.
Documentation and Communication
- All notices and communications regarding rent increases should be documented in writing for legal clarity and future reference.
