The median household income in Delaware is $72,724/year, and average rent for a 2-bedroom apartment runs $1,200/month. A storage unit at $100/month represents 1.7% of annual household income. That is roughly in line with the national average of 1.5%, meaning storage is proportional to what Delaware residents earn.
Delaware’s no-sales-tax status applies to storage unit rentals too. Philadelphia residents sometimes rent across the border in Delaware to avoid Pennsylvania’s sales tax on storage, saving $10-$15/month on the tax alone.

Storage unit prices by size in Delaware
| Size | Area | What Fits | Standard | Climate-Controlled |
|---|---|---|---|---|
| 5×5 | 25 sq ft | Closet. 10-15 boxes, small furniture. | $42/mo | $55/mo |
| 5×10 | 50 sq ft | Walk-in closet. Studio apartment contents, mattress set. | $65/mo | $85/mo |
| 10×10 | 100 sq ft | One-car garage. 1-2 bedroom apartment. | $100/mo | $130/mo |
| 10×15 | 150 sq ft | Large garage. 2-3 bedroom home plus appliances. | $135/mo | $180/mo |
| 10×20 | 200 sq ft | Parking space. 3-4 bedroom home or vehicle storage. | $165/mo | $215/mo |

Cost per square foot in Delaware
Larger units cost more per month but less per square foot. A 5×5 in Delaware runs $1.68/sq ft/month while a 10×20 runs $0.82/sq ft/month and a 10×30 runs $0.77/sq ft/month. If you need a lot of space, one large unit is cheaper than two small ones. But if you only need 60 square feet, renting a 10×10 (100 sq ft) means paying for 40 square feet of empty air at $1.00/sq ft/month.
How Delaware storage costs compare
Is climate-controlled storage worth it in Delaware?
Climate control adds $30/month (a 30% premium) to your Delaware storage bill. Over 12 months, that is $360 extra. Whether that premium is justified depends entirely on what you are storing and how Delaware’s climate affects your belongings.
Delaware’s humid subtropical climate makes CC advisable for wood furniture and electronics, especially in the summer months. Beach area facilities (Rehoboth, Lewes) see higher humidity and salt air exposure. New Castle County (Wilmington area) is slightly less humid but still benefits from CC for long-term storage.
Store in climate control in Delaware: Wood furniture, leather goods, electronics, musical instruments, artwork, photographs, documents, wine, and anything fabric-based stored longer than 3 months. Humidity is your primary enemy here.
Standard storage is fine for: Metal tools, outdoor furniture, plastic bins of holiday decorations, sporting equipment, and appliances. These items tolerate Delaware’s humidity without damage.
Weather and climate risks for storage in Delaware
Coastal storms affect beach communities October-April. Moderate snow in northern Delaware. Summer humidity moderate but consistent.
These conditions affect how you should choose and use storage in Delaware. Interior hallway units inside concrete buildings offer more protection than exterior drive-up metal units. If your area faces flooding risk, check the facility’s flood zone status at fema.gov/flood-maps before signing a lease.
Best and worst times to rent storage in Delaware
Most expensive: May-September. Delaware facilities charge a 18% premium during peak season, pushing a standard 10×10 to roughly $118/month.
Cheapest window: November-February. Off-peak rates drop 15% below peak to roughly $85/month. That is $33/month in savings, or $396 over a full year.
The rate you lock in at move-in becomes your base for future increases. Starting at an off-peak rate of $85/month means that even after a 10% increase at month 12, you are paying $93/month. Starting at a peak rate of $118/month means that same 10% increase takes you to $129/month. The gap compounds over time.
Types of storage available in Delaware
Delaware has a moderate number of storage facilities concentrated in Wilmington, Dover, Newark. National chains serve the largest metros while independent operators fill gaps in smaller markets. Competition is adequate in urban areas but limited in rural communities.
Self-storage (drive-up): The most common type. Pull your vehicle up to the unit door, load and unload directly. Available in standard and climate-controlled versions. In Delaware, standard drive-up 10×10 units average $100/month.
Self-storage (interior hallway): Units inside a building accessed through hallways and elevators. Better climate control and security, but harder to move large items in and out. Climate-controlled hallway units in Delaware average $130/month for a 10×10.
Portable containers (PODS, etc.): A container is delivered to your home, you pack it, and the company stores it at their facility. More expensive than self-storage (typically $150-$220/month for a similar volume) but eliminates the loading and driving. Best for move-related storage.
Vehicle and boat storage: Outdoor parking ($50-$100/month in Delaware), covered ($75-$150/month), and indoor enclosed ($150-$350/month). If you are storing a vehicle, boat, or RV, confirm the facility accepts your specific vehicle type and size before signing.
Hidden fees at Delaware storage facilities
The advertised rate of $100/month is rarely what you actually pay. Here are the common add-ons in Delaware.
| Fee | Typical in Delaware | Notes |
|---|---|---|
| Admin / setup fee | $20-$30 | One-time at move-in. Some facilities waive with online booking. |
| Mandatory insurance | $15-$25/mo | Required at most facilities. Your renter’s or homeowner’s policy may satisfy this. |
| Late payment fee | $31-$51 | After 5-10 day grace period. Set up autopay to avoid. |
| Lock purchase | $15-$25 | Some facilities require their specific lock. Others let you bring your own. |
| Move-out cleaning | $25-$50 | Not universal. Ask at move-in. Leave the unit broom-clean to avoid. |
Ask for the total all-in monthly cost before comparing facilities. A facility advertising $100/month that requires $15/month insurance and a $20 admin fee is really $115/month ongoing plus $20 upfront.
Local storage tips for Delaware
Delaware is small enough that you can compare prices across the entire state in 30 minutes of research. The Wilmington-Newark corridor has the most options and best prices. Beach community storage (Rehoboth, Bethany) is seasonal – rates spike in summer when vacation rental turnover creates demand. Many Philadelphia-area residents use Delaware facilities for the tax advantage (no sales tax on the rental). Dover has moderate options at moderate prices.
How to save on storage in Delaware
Rent during November-February. Off-peak rates save $33/month in Delaware. Over 12 months, that is $396. The rate you lock in at move-in stays as your base, so a lower starting point saves money for the life of the rental.
Right-size your unit. A 10×10 at $100/month versus a 10×15 at $135/month saves $420/year. Most people rent one size too large. Disassemble furniture, stack boxes to the ceiling, and fill empty space inside dressers and appliances. A well-packed 10×10 holds more than a loosely packed 10×15.
Drive 15-20 minutes from the city center. Suburban Delaware facilities charge 20-35% less than urban locations. If you access your unit once a month, the drive saves $25-$35/month.
Check your existing insurance. Your homeowner’s or renter’s policy may cover items in storage at no additional cost. If so, decline the facility’s $15-$25/month protection plan and save $180-$300/year.
Negotiate. Show a competitor’s rate. Ask about unadvertised specials. Offer to prepay 3-6 months for a discount. Military, student, and senior discounts exist at many Delaware facilities but are never posted. You have to ask.
Most Delaware facilities raise rates 5-10% after 6-12 months. After 2 years, the average tenant pays 15-25% more than a new customer renting the identical unit next door. Set a calendar reminder at month 10. If the increase exceeds 5%, negotiate or switch. A truck rental costs $40-$80. The savings from switching recoup that in 2-3 months.
How Delaware compares to neighboring states
| State | Standard 10×10 | Climate-Controlled | vs Delaware |

| Maryland | $115/mo | $150/mo | -13% |
