Storage units are usually rented, not bought — but you can purchase one if you own the building or land

Most people rent storage units month to month from a facility owner or management company. If you want to own a storage unit outright, your options are limited: you can buy a storage facility building itself (a commercial real estate purchase), buy a unit inside a self-storage complex that allows individual ownership, or build a storage structure on land you already own. The first two routes involve significant capital and are treated as real estate investments, not straightforward purchases. The third — building on your own property — is the most straightforward path for a homeowner.

Before you pursue any of these, understand what you are actually buying. A storage unit you own still requires you to pay property taxes, insurance, and maintenance. If it sits inside a larger facility, you may owe homeowners association fees or facility fees. You cannot straightforward buy a unit and walk away — ownership comes with ongoing costs and responsibilities that renting avoids entirely.

Key Takeaways

  • Most storage units cannot be purchased individually; they are rented from facility owners who retain the building.
  • Buying a storage facility building or a unit within one that allows ownership requires treating it as a commercial real estate investment with a mortgage, property taxes, and insurance.
  • Building a storage structure on land you own is simpler than buying an existing unit but requires zoning approval, building permits, and compliance with local codes.
  • Renting a storage unit is almost always cheaper and simpler than buying, since you avoid property taxes, insurance, and long-term maintenance costs.
  • If you are considering ownership for investment, consult a real estate attorney and accountant to understand tax implications and liability.

Buying an individual storage unit within a facility

Some self-storage complexes allow buyers to purchase individual units as real estate investments. These are rare and typically found in larger metropolitan areas where storage demand is high. When a facility offers this model, you own the unit itself but not the land or common areas — the facility owner retains those and charges you a monthly or annual fee for maintenance, security, insurance of common areas, and property management.

The purchase process resembles buying a condo. You will need a mortgage (most lenders treat storage units as commercial property, so rates and terms differ from residential mortgages), a title search, an inspection, and a purchase agreement. You will also pay closing costs, which typically run 2 to 5 percent of the purchase price. After closing, you own the unit but remain responsible for property taxes on your portion of the land, your own insurance, and the facility's monthly or annual fees.

Before pursuing this route, ask the facility owner directly whether units are for sale. Most are not. If they are, request the facility's governing documents, fee schedules, and any restrictions on what you can store or how you can use the unit. Some facilities prohibit renting your unit to others, which eliminates the investment upside.

Buying a storage facility building as a commercial investment

If you want to own an entire storage facility, you are buying commercial real estate. This requires a commercial mortgage (typically 20 to 25 percent down payment, rates higher than residential mortgages, and terms of 10 to 20 years), a commercial real estate agent, a property appraisal, and a commercial real estate attorney to review the purchase agreement and title.

The facility itself must generate enough rental income from tenants to cover your mortgage, property taxes, insurance, maintenance, utilities, staffing, and marketing. Most self-storage facilities operate on thin margins — typically 20 to 40 percent profit after expenses. You will also need to manage tenant relationships, handle evictions if rent goes unpaid, and maintain the building and grounds. This is a business, not a passive investment.

Before making an offer, hire an accountant to review the facility's income and expense records for the past three to five years. Ask the current owner for tenant rolls, lease terms, occupancy rates, and any pending repairs. A facility with 60 percent occupancy is not the same as one with 90 percent occupancy, and deferred maintenance can cost tens of thousands to address.

Building a storage structure on your own property

If you own land and want to build a storage building for personal use or as a rental investment, start by checking your local zoning code. Many residential zones prohibit commercial storage buildings or limit their size and appearance. Contact your city or county planning department and ask whether a storage building is permitted on your property and what setback requirements (distance from property lines) explore.

Once zoning is confirmed, you will need a building permit. The permit process requires architectural plans, proof of property ownership, and payment of permit fees (typically $500 to $2,000 depending on the building size and your location). The building itself must meet local codes for foundation, framing, roofing, and electrical systems if you plan to add lighting or climate control.

Hire a contractor with experience building storage structures. Get at least three written bids that specify materials, labor, timeline, and warranty. A basic 10-by-20-foot storage shed runs $3,000 to $8,000 depending on materials and local labor costs; a larger climate-controlled structure can cost $15,000 to $40,000 or more. After construction, you will owe property taxes on the added structure value and will need to insure it if you are renting units to others.

Why renting is usually the better choice

Buying a storage unit or building ties up capital, creates ongoing tax and insurance obligations, and leaves you responsible for repairs and maintenance. Renting a unit costs less upfront, requires no mortgage or down payment, and shifts maintenance responsibility to the facility owner. If you need storage for only a few years, renting is almost certainly cheaper.

Buying makes sense only if you plan to hold the property long-term and can generate enough rental income (if you are renting units to others) to justify the costs. Even then, the return on investment is modest — most self-storage facilities return 5 to 10 percent annually after all expenses, which is comparable to stock market returns but with far less liquidity and much more work.

If you are storing your own belongings, renting is the clear winner. You avoid property taxes, insurance premiums, maintenance costs, and the hassle of managing a property. Month-to-month rental agreements also give you flexibility to downsize or relocate without being locked into a long-term commitment.

What to do if you decide to buy

If you still want to pursue ownership, start by consulting a real estate attorney licensed in your state. They can review purchase agreements, explain your liability as a property owner, and identify tax implications. Many storage unit purchases involve commercial property, which has different legal rules than residential real estate.

Next, hire a commercial real estate agent who specializes in storage properties in your area. They can show you available units or facilities for sale, help you understand market prices, and negotiate on your behalf. Ask for references from past clients and verify they have experience with storage properties specifically.

Finally, work with a commercial lender or mortgage broker to understand financing options. Commercial mortgages have stricter requirements than residential mortgages — lenders will want to see proof of income, a detailed business plan, and often require 20 to 25 percent down. Getting pre-approved before you make an offer tells you what you can actually afford.

Frequently Asked Questions

Can I buy a storage unit and rent it out to make money?

Only if the facility allows it and you own the unit outright or have a long-term lease. Most facilities prohibit tenant subleasing. Even where it is allowed, rental income is modest — typically $100 to $300 per month depending on unit size and location — and you must account for property taxes, insurance, and facility fees, which often consume half or more of that income.

What happens if I buy a storage unit and the facility closes?

If you own the unit, you own the physical structure. The facility owner cannot force you out, but you lose access to the facility's security, climate control, and common areas. You would need to arrange removal of the unit or negotiate with the new owner if the property is sold. This is why reviewing the facility's financial health and ownership stability matters before buying.

Do I need a mortgage to buy a storage unit?

Most buyers use a commercial mortgage, but you can pay cash if you have the funds. Commercial mortgages typically require 20 to 25 percent down and charge higher interest rates than residential mortgages. Some lenders will not finance storage units at all, so shop around before committing to a purchase.

Can I build a storage unit on residential property?

It depends on your local zoning code. Many residential zones allow small storage sheds for personal use but prohibit commercial storage buildings or renting units to others. Contact your city or county planning department to confirm what is permitted on your property before you build.

Is buying a storage unit a good investment?

Storage facilities typically return 5 to 10 percent annually after expenses, which is modest compared to other real estate investments. The work involved — managing tenants, handling maintenance, dealing with vacancies — is significant. For most people, renting a unit when needed is far simpler and cheaper than buying.
