What self-storage units are
A self-storage unit is a space you rent inside a storage facility. Common unit sizes include 5x5 feet, 5x10, 10x10, and 10x20. Some are indoors in hallways. Some are ground-level with drive-up access.
You load and unload the unit yourself. You usually sign for a month-to-month rental, though some facilities offer longer terms. Many locations have gate access, cameras, carts, elevators, and different access hours.
Self-storage is different from portable storage. With portable storage, a container comes to you. With self-storage, you take your things to the facility. If you want help comparing both, see our services.
- Small closet-size storage often starts around 5x5 feet
- A 10x10 unit can fit the contents of about 1-bedroom apartment
- A 10x20 unit can hold items from a 2 to 3-bedroom home, depending on furniture size
Who self-storage units suit
Self-storage works well if you want regular access to your things. You can visit the facility during access hours to grab boxes, swap seasonal items, or check on business inventory. It is often a good fit for people between leases, downsizing, remodeling, or moving to a new city.
It can also help new immigrants and families who need a simple place to keep belongings while housing, jobs, or school plans are getting settled. If you do not know what size you need, our guide on how much storage do I need can help.
This option may be less ideal if you cannot drive to a facility or if you want the storage brought to your home. In that case, another type of storage may fit better. StowMatch can help you compare options for your city and timeline.
- Good for short-term or long-term use
- Useful if you need access many times during the month
- Often chosen for furniture, boxes, bikes, tools, and business stock
Typical costs
Self-storage prices vary by city, unit size, floor level, and features. Climate-controlled units often cost more than standard units. Ground-floor and drive-up units may also cost more because they are easier to reach.
Typical ranges, not quotes, can look like this. A 5x5 unit may run about $30 to $90 per month. A 5x10 may be about $50 to $140. A 10x10 may be about $90 to $220. A 10x20 may be about $140 to $350 or more in high-cost areas.
Ask about other charges before you rent. Some facilities charge an admin fee, require a lock purchase, or offer tenant insurance for an added monthly cost. Intro rates can change after the first month or first few months, so check the regular rate too.
- Climate control usually costs more
- First-floor or drive-up access can cost more
- Insurance, lock, and admin fees may be extra
What to check before you rent
Start with size. It is cheaper to choose the right unit than to rent too much space for months. Measure large furniture, count your boxes, and think about whether you need walking room inside the unit. If you want a quick estimate, visit our storage size guide.
Next, check access and rules. Look at gate hours, office hours, elevator access, loading areas, and whether you can use your own lock. Ask if the unit is climate controlled, especially for wood furniture, electronics, photos, documents, or items sensitive to heat and humidity.
Also ask about safety and cleanliness. A clean facility, good lighting, carts, cameras, and clear pest control practices all matter. Read the rental terms carefully. Check late fees, move-out notice rules, and whether the price can change after a promo period.
- Confirm exact unit dimensions and ceiling height
- Ask about access hours on weekends and holidays
- Check if your items need climate control
- Review fees and rate-change terms before signing

Common questions
How do I know what self-storage unit size I need?
Start with your largest items, then count boxes and leave some walking space if you need regular access. Our size guide can help you estimate.
Can I visit my self-storage unit anytime?
Usually not anytime. Most facilities have set gate and office hours, so check access times before renting.
Do I need climate control?
It depends on what you store. Climate control is often a smart choice for electronics, papers, photos, wood furniture, and items sensitive to heat or moisture.
Does StowMatch rent the unit to me?
No. StowMatch is a free matching service that helps you compare options. The storage facility handles the rental agreement and pricing.
