How to Store Documents, Files, and Business Records Securely
Why Proper Document Storage Matters
Every business has paperwork — and lots of it. From financial records and legal contracts to blueprints and client files, these documents often need to be kept for years. But simply shoving them into a closet or basement can lead to damage, misplacement, or security risks.
If you're downsizing your office, going paperless, or just need more space, off-site document storage is the smart solution.
Know What to Keep (and for How Long)
Different industries have varying document retention guidelines. A few general rules:
- Tax records: 7–10 years
- Employee files: 3–7 years after termination
- Client contracts: Duration + 3–5 years
- Medical records: 6+ years (varies by state)
Create a record retention policy so you're not storing unnecessary paperwork forever.
Sort and Label Everything
Before storing, sort files into categories (e.g., financial, legal, employee, client). Use sturdy, labeled file boxes or plastic totes. Color-coded folders and index sheets can help with faster retrieval later. Be sure to label all sides of each box.
Pro Tip: Number your boxes and keep a digital inventory that lists which documents are inside each box.
Choose the Right Containers
Paper is vulnerable to moisture, pests, and deterioration. Use:
- Plastic, sealable totes with lid clips
- Acid-free folders and dividers
- File cabinets (for long-term or high-value storage)
Avoid cardboard boxes in humid areas unless your unit is climate-controlled.
Use a Climate-Controlled Storage Unit
Humidity and heat can warp, fade, or mildew paper documents — especially in the Bay Area's fluctuating climate. Storage Corner offers climate-controlled units ideal for protecting sensitive business records year-round.
Did you know? Even short exposure to heat or damp air can cause ink to fade and paper to curl.
Focus on Security & Privacy
Your stored documents may include personal, medical, or financial info. That’s why you need:
- Gated facility access with personal PINs
- 24/7 video surveillance
- Lockable storage units
- Optional tenant protection plans
Digitize for Backup, Then Store the Originals
Before placing your files in storage, scan them and back up to cloud or encrypted drives. This gives you access when you’re off-site and provides a second copy in case of damage.
Pairing digital with secure physical storage is a best-practice for modern businesses.
