What Does NAICS Code 531130 Cover?
According to the official 2022 NAICS data, code 531130 covers establishments primarily engaged in renting or leasing space for self-storage, providing secure space such as rooms, compartments, lockers, containers, or outdoor space where clients can store and retrieve their goods.
In simple terms, this code applies to any business whose main activity is renting out storage space rather than storing its own inventory. This includes:
- Self-storage facilities renting individual units to the public
- Miniwarehouse operators leasing small, secure storage spaces
- Climate-controlled storage facility operators
- Outdoor storage and U-lock facilities renting vehicle, RV, or boat storage space
- Equity real estate investment trusts (REITs) primarily leasing self-storage properties
The important word here is leasing. This code is for renting storage space to others, not for businesses that store, warehouse, or distribute their own goods or someone else’s goods as a service.
Does My Storage Business Qualify for Code 531130?
Your business qualifies for NAICS code 531130 if:
- You rent individual storage units or space directly to customers
- Customers retain access to and control over their own stored items
- Your main source of revenue comes from leasing storage space, not handling or moving goods
- You operate a facility marketed as self-storage, miniwarehouse, or similar
Your business may not qualify if:
- You provide general warehousing and storage services where you handle, manage, or distribute the goods on a client’s behalf, which falls under 493110, General Warehousing and Storage, instead
- You store goods only for your own business, which is not a leasing activity and falls outside this code
- Your storage offering is incidental to a moving company or logistics service, which may fall under transportation and warehousing codes instead
When your business sits between two codes, always classify based on whichever activity generates the most revenue.
