Here is how to start a self storage business: prove demand in a three to five mile trade area, pick a path (build, buy or convert), write a plan a lender will fund, then set up software, gate access and phones before you open. Building runs about 50 to 120 dollars a square foot before land, and lease-up to 85 percent occupancy can take up to three years.
Key takeaways
- The US had 57,981 self storage facilities and about 2.65 billion rentable square feet in the 2025 Self-Storage Almanac, using Radius+ data.
- Construction costs about $50 to $65 a square foot single-story and $90 to $120 multistory, before land, per a December 2025 Storable guide. A 60,000 square foot build comes to about $3.96 million before land.
- The big REITs reported 90.4 to 94.2 percent same-store occupancy in Q2 2026, but Marcus & Millichap expects asking rents to fall for a fourth straight year in 2026.
- 34 percent of first contacts with a storage facility came by phone in the SSA's 2017 Demand Study, and nearly 60 percent of customers rented from the first facility they reached.
Three ways into self storage: build, buy or convert
Every self storage business starts with one decision: build a new facility, buy one that already has tenants, or convert an existing building. The choice sets your budget, your timeline and how long you wait for the first real cash flow. Here is how the three compare on the numbers that are actually published.
| Path | Upfront cost | Time to steady income | Main risk |
|---|---|---|---|
| Build new | $50 to $120 a sq ft to build, plus $4.25 to $8 a sq ft site work, plus land | Permits and construction, then up to 36 months to reach 85% occupancy | Lease-up runs slower than the pro forma |
| Buy existing | Priced on income: 2025 cap rates ran 5% to 5.5% (Class A) up to 6.75% to 8% (Class C), or $110 to $215 a sq ft | Day one, if occupancy is real | Paying for rents the market no longer supports |
| Convert a building | Depends on the shell, the roof and the code upgrades | Shorter than a build, since the shell exists | Zoning, fire code and a layout that wastes space |
Most first-time owners do better buying a small, under-managed facility than building. You see real rent rolls instead of a forecast. The catch is price: IRR's 2026 Self Storage Report found values down roughly 10 to 15 percent from 2022 peaks, with cap rates wider across every class. Sellers who bought at the top still price like it is 2022.
How to start a self storage business, step by step
Starting a self storage business takes eight steps, in this order: market study, site, path, plan and financing, legal setup, operating systems, phones and marketing, and lease-up. Skipping the first step is how facilities end up half empty next to three new competitors.
- 1
Prove the demand
Draw a three to five mile radius. Count competing facilities and their square feet, call each one for prices, and note what is under construction. Supply per person swings widely: the 2025 Almanac put Idaho at 15.7 rentable square feet per capita and Hawaii at 3.41. - 2
Find the site and check zoning
Storage needs visibility, easy truck access and the right zoning. Developers typically want 2.5 to 5 acres for a new build. Call the planning department before you make an offer, not after. - 3
Choose build, buy or convert
Use the table above. If you buy, get the trailing 12 months of rent rolls and bank deposits, not the broker's pro forma. - 4
Write the business plan and line up financing
Lenders want the market study, a unit mix, pricing, a monthly lease-up forecast and your equity. The business plan section below covers what goes in it. - 5
Form the company and the paperwork
An LLC, a business bank account, insurance, a rental agreement and your state's lien law. See the legal section below. - 6
Set up the operating systems
Management software, online rentals, autopay, gate access tied to payment status. The self storage automation guide covers what to automate first. - 7
Set up the phone and the marketing
A Google Business Profile, a website that rents units at 10pm, and a phone line that answers every call, including nights and weekends. - 8
Lease up
Pre-lease before opening, price to fill, and raise rates as you pass 85 percent. Track move-ins by source so you know which ads work.
How much does it cost to start a self storage business?
Building a new facility costs about 50 to 65 dollars a square foot single-story and 90 to 120 dollars multistory, plus 4.25 to 8 dollars a square foot of site work, before land. That is the range in Storable's December 2025 construction guide, drawing on Mako Steel and The Parham Group. Its worked example: a 60,000 square foot facility at 60 dollars a square foot plus 6 dollars of site work comes to about 3.96 million dollars, land not included.
Treat any single number with suspicion. Back in 2022, a developer writing in Inside Self-Storage reported single-story costs had already jumped to 65 to 85 dollars a square foot, and that bad soil or drainage could add 100,000 to 400,000 dollars to site prep. The ground you buy decides more of the budget than the brochure does.
| Cost line | Published range | Notes |
|---|---|---|
| Land | Quoted per site | Developers typically need 2.5 to 5 acres |
| Site development | $4.25 to $8 a sq ft | Parking, landscaping, signage; bad soil adds $100,000 to $400,000 or more |
| Single-story building | $50 to $65 a sq ft | Drive-up units; the 2022 estimate ran $65 to $85 |
| Multistory building | $90 to $120 a sq ft | Climate control and elevators cost more and rent for more |
| Gate, cameras, access control | Quoted per site | Ties tenant access to payment status |
| Management software | Monthly subscription | Online rentals, autopay, lien notices |
| Phone answering | $39 to $799 a month | AI from $39 (callflo.ai Starter, annual); C3 storage call center $599 to $799 plus $350 setup |
| Lease-up reserve | Your lender sets it | Covers debt service while occupancy climbs |
The phone line prices are from the C3 call center pricing page and callflo.ai's own pricing page, read in October 2026.
Buying is priced differently: on net operating income and a cap rate. A facility earning 300,000 dollars a year in net income at a 6 percent cap rate is worth about 5 million dollars. IRR put 2025 cap rates at 5 to 5.5 percent for Class A, 5.75 to 6.5 percent for Class B and 6.75 to 8 percent for Class C. Older, smaller facilities cost less per dollar of income, and they are also where a new owner can add the most.
Staffed, remote or hybrid: choosing how to run it
You can run a facility with a manager on site, with nobody on site, or with a manager who covers several sites. The choice drives payroll, the most controllable cost you have. It also decides who answers the phone, opens a stuck gate, and walks the property after a storm.
| Model | Who is on site | Works best when | Watch out for |
|---|---|---|---|
| Staffed | A manager during office hours | Larger facilities, older customers, higher crime areas | Payroll, and calls that ring out after hours |
| Hybrid | A regional manager covering several sites | A small portfolio within driving distance | Response time when two sites need someone at once |
| Remote | No one; kiosks, online rentals, cameras | Small facilities with good access control and internet | Deferred maintenance and customers who want a person |
Remote is not free of people. Inside Self-Storage's 2024 analysis of automation and facility value lists the risks: local crime that calls for a presence, older tenants who prefer a human, and maintenance that slips when nobody walks the lot. Plan for a local person on call for lockouts, inspections and repairs, and for a way to answer every phone call that does not depend on that person.
Running it lean: unstaffed facilities and the phone
Many new owners plan to run the facility with no one on site. That is realistic now. Inside Self-Storage describes operators running fully unmanned and semi-manned sites, with a regional manager covering several facilities and software handling rentals, payments and gate codes. What those plans tend to forget is the phone.
Sunday, 6:15pm. A couple closing on a smaller house needs a 10x15 by Tuesday. They call the three facilities nearest the new address. Your site has no office hours on Sunday, so the call goes to voicemail. They rent from the facility that picked up. You paid for the land, the building and the ads, and lost the tenant in one ring.
The research says this is the normal case, not the edge case. Inside Self-Storage, reporting on the SSA's 2017 Demand Study, found 34 percent of first contacts came by phone and nearly 60 percent of customers rented from the first facility they reached. Online rentals help, but they do not close the gap. On its Q2 2026 earnings call, Public Storage, the most digital operator in the business, said about three-quarters of customers lease fully online. One in four still does not.
Existing tenants call too, about gate codes, hours, and paying a late bill. At an unstaffed site, each of those calls either rings a manager's cell or goes nowhere.
Crooked River Self Storage runs two locations on one number with callflo.ai answering. On the VIP plan, the team built an integration into their storage software, so the agent quotes live availability, reserves units, looks up gate codes and takes payments by phone. About a quarter of their calls land after hours or on weekends. The AI receptionist for self storage post walks through that setup call by call.
Sample call: Sunday evening rental
On a new facility, start with what is cheap and fast. callflo.ai Starter is 39 dollars a month on annual billing (49 dollars month to month), with 120 minutes of calls included and 98 cents a minute after. It answers from your website and texts the caller; the pricing page shows which plan adds calendar booking and card payments through Stripe. VIP, at 697 dollars a month on annual billing, adds 1,000 minutes and a team that builds the integration into your software. The automation guide explains why the phone comes before kiosks and smart locks.
Hear it answer a storage call before you open
Call callflo.ai's own AI agent and ask it anything about your business. When you are ready, pick a plan: no setup fee, no contract, and you do not pay unless you are satisfied.
Starter is $39 a month on annual billing. Live on your line about 5 minutes after you sign up.
Choosing the unit mix and setting prices
The unit mix is how many of each size you build or keep, and it should come from your market study, not a template. Call every competitor in the trade area, ask for a 5x10, a 10x10 and a 10x20, and ask which sizes are sold out. Sold-out sizes are your demand signal. Their prices are your starting point.
- Small units (5x5, 5x10). Boxes, seasonal items, apartment renters. The highest rent per square foot.
- Mid units (10x10, 10x15). A one or two bedroom move. Usually the core of the mix.
- Large units (10x20, 10x30). A full house, a business, a contractor's inventory. Lower rent per square foot, longer stays.
- Climate controlled. Costs more to build and rents for more. Worth it where summers are hot or humid, or near high-value customers.
- Vehicle and RV parking. Cheap to build on spare land, but check zoning and your state's lien rules for vehicles.
For a national reference point, Marcus & Millichap expects average asking rent of 1.18 dollars a square foot a month in 2026. At that rate a 10x10, which is 100 square feet, would ask about 118 dollars a month. Your market can sit far above or below that, which is why the phone calls to competitors matter more than any national average. Price new units to fill, then raise rates on new move-ins as each size passes 85 to 90 percent occupancy.
What goes in a self storage business plan
A self storage business plan is the document a lender or partner reads before funding you. It needs the market study, the site, the unit mix and pricing, a month-by-month lease-up forecast for at least three years, operating costs, the financing structure and your own equity. Keep it short and put the numbers where they can be checked.
- Executive summary. What you are building or buying, where, the total cost and what you are asking for.
- Market analysis. Population and growth in the trade area, competing square feet, their street rates, and anything under construction.
- Unit mix and pricing. How many 5x5s, 10x10s and 10x30s, climate controlled or not, and the rate for each.
- Lease-up forecast. Occupancy by month until stabilized. Industry operators treat 85 percent as stabilized.
- Operations. Staffed, remote or hybrid; access hours; software; who answers the phone.
- Financials. Revenue, expenses and cash flow for three to five years, with a downside case.
- Financing. Loan, equity and reserves. The next section covers the options.
One assumption to defend line by line: rent growth. Plans written in 2021 assumed it would keep rising. It has not. Marcus & Millichap expects asking rents to fall for a fourth straight year in 2026, as the section on whether storage is a good business shows.
How to finance a self storage business
Most self storage businesses are financed with a commercial or SBA loan plus the owner's equity. Lenders fund a buyout more easily than a ground-up build, because an existing facility has income they can underwrite. New builds usually need more equity and a lease-up reserve.
- SBA 504. Up to 5.5 million dollars for land, buildings and long-life equipment, with 10, 20 and 25 year terms. It cannot fund working capital. Details on the SBA's 504 page.
- SBA 7(a). Up to 5 million dollars, and it can cover real estate, equipment and working capital in one loan. See the SBA's 7(a) page.
- Conventional bank loans. Local and regional banks lend on storage, usually with more equity required than SBA programs.
- Seller financing. Common on small, older facilities where the owner wants out and the bank wants more history.
- Partners. Investors put in equity for a share of cash flow and the sale. Put the split and the exit in writing.
Is self storage a good business in 2026?
Self storage can still be a good business in 2026, but it is a location business, not an easy one. Occupancy at the big operators is high, and new supply is slowing. Rents have been falling for years, so a facility bought or built on 2021 math may not pencil. Markets with little new construction are doing better than the national average.
The occupancy figures come from the REITs' own Q2 2026 results: Public Storage at 92.5 percent, Extra Space at 94.2 percent and CubeSmart averaging 90.4 percent. Public Storage also reported revenue down 0.6 percent on lower rent per square foot. The supply and rent forecast is from Marcus & Millichap's 2H 2026 national report, which expects average asking rent of 1.18 dollars a square foot a month and vacancy near 10 percent by year end. IRR expects national occupancy of 87 to 89 percent through 2026.
Demand has held up. The 2025 Self Storage Demand Study counted 12.6 percent of US households renting a unit. People keep storing things when they move less, downsize, or inherit a house full of furniture. What changed is competition: in markets where 5 to 9 percent of inventory is under construction, IRR flags the risk of a long lease-up and heavy discounting.
Where it tends to work
- A trade area with low square feet per person and nothing new in the pipeline.
- An existing facility with weak management: below-market rates, no online rentals, a phone nobody answers.
- An owner who can run it lean, with remote access and automation, so payroll does not eat the margin.
Permits, the rental agreement and lien law
Self storage is regulated mostly at the state and local level. You need the right zoning and building permits, a rental agreement that covers rate changes, access, insurance and default, and a process for delinquent units that follows your state's lien law. Those laws differ on notice periods, notice by email, and how a lien sale is advertised.
The Self Storage Association keeps a page of state lien and tenant insurance laws, and most states have their own association that tracks changes. This is not legal advice. Have a local attorney review your rental agreement and your first lien sale before you run one.
If storage is part of a wider portfolio of rentals, the property managers page shows the same answering setup on a leasing line.
