To overlock a storage unit, you put your own lock on the tenant's door after they default, and you do it only when your lease allows it and your state's rules on timing and notice are met. Record what you did, tell the tenant how to restore access, and remove the lock the day they pay.
This guide is general information, not legal advice. Overlocking is regulated by state law and varies a lot. Review your lease, your policy and your notices with your attorney before you use it.
What overlocking is
An overlock is a lock you add to a unit, either over the tenant's lock or after cutting it, so the tenant cannot get in until the balance is paid. A gate lockout does the same job by turning off the tenant's code at the gate. See the gate code entry too.
Why owners do it: it gets attention fast, it protects the goods that secure your lien, and it keeps a delinquent tenant from emptying the unit before you can act.
What the law says (and does not say)
State statutes treat this differently. Here are a few examples from official sources, not a full list.
| State | What the statute says | Source |
|---|---|---|
| Washington | Owner may deny access when rent or other charges are unpaid for six consecutive days, if the rental agreement so provides | RCW 19.150.030 |
| Nevada | A section of NRS 108 covers denial of access to a storage space when charges are unpaid, with notice | NRS 108.476 |
| Texas | Chapter 59 has no express overlock rule. The owner enforces through a contractual lien that must be underlined or in conspicuous bold in the written agreement | Tex. Prop. Code 59.041, 59.042 |
| Florida | The sections researched do not address overlocking, so any right comes from the rental agreement | Fla. Stat. 83.801 to 83.809 |
| New York | Does not address overlocking, and refusing to give goods back after the tenant pays permitted fees is an unlawful detention with treble damages risk | N.Y. Lien Law 182 |
Other states, such as Colorado, Connecticut and New Jersey, tie denial of access to what the rental agreement says and require the lien notice to mention it. The Washington and Nevada rows were checked against the legislature's own website for this page. The others come from our state research files; always confirm the current text yourself. Look up your state on the self storage lien laws hub.
The common themes:
- Your rental agreement usually needs to authorize denial of access.
- Some states set a minimum number of days. Others set none.
- Some require notice; some allow it without notice.
- Access denial does not end the tenant's debt. Rent normally keeps accruing.
- You still must use the lien process to sell. An overlock is not a sale.
- If the tenant pays, access must be restored.
Step 1: Put it in the lease
Your rental agreement should say, in plain words, that you may deny access when rent or fees are unpaid, and that the tenant stays responsible for rent. Sample wording to give your attorney as a starting point:
If rent or other charges are not paid by the date stated in this agreement, Owner may deny access to the unit and place a lock on it. Access will be restored when all amounts due are paid. Rent continues to accrue while access is denied.
Do not treat this as ready-made. See writing a good self storage lease.
Step 2: Write a one-page overlock policy
Decide in advance and write down:
- The day it happens (for example, the day after the grace period ends, or the minimum day your state permits).
- Who may place a lock.
- Who is told (the tenant and listed alternate contact only).
- How the tenant pays to restore access.
- Who removes the lock and how fast (the same day).
- What you record.
Use the same rule for every tenant.
Step 3: Tell the tenant first, if you can
Even where notice is not required, a message before the lock is good practice and cuts calls and disputes. Keep it short.
Your rent of $95 for unit B12 was due on the 1st. Your account is now past due. If it is not paid by [date], access to your unit will be restricted under your rental agreement. Pay at [link] to avoid this.
Do not mention the contents. Do not threaten.
Step 4: Place the lock
- Check the account first. Make sure no payment came in that morning.
- Check the unit. Confirm you have the right unit number and that it is in default.
- Never enter the unit to do this. Place the lock on the door.
- Use a lock marked with the unit, date and your phone number.
- Photograph the door with the lock on it and the date.
- Record it in the tenant's account notes.
- Send a notice with the amount due, the date and how to restore access.
If a tenant's own lock is on the door, follow your lease and state law about cutting it. Ask your attorney before cutting any lock, and know that doing it wrong can create a claim for damage.
Step 5: Restore access fast
The tenant pays. You must act at once.
- Remove the lock the same day, or turn the gate code back on right away.
- If it is after hours, tell the tenant when access will return, and keep that promise.
- Note the date and time of removal in the account.
Holding goods after the full balance is paid is the mistake that creates the biggest claims. New York's statute is a good example of why: it treats refusing to surrender goods after payment as unlawful detention.
Step 6: Keep the lien clock moving
An overlock is a pause, not a solution. Start your lien timeline on the first day your state allows. Use the lien timeline calculator, and read collections without lawsuits and how to reduce delinquency.
Gate lockout vs overlock
| Overlock | Gate lockout | |
|---|---|---|
| What it blocks | The unit door | The facility gate and any codes |
| Needs a person on site | Yes | No |
| Works for unmanned sites | Hard | Yes |
| Tenant can still reach the door? | No | Only if someone lets them in |
| Fast to undo | Needs a trip | Instant, from software |
| Cost | Locks | Gate system |
Many unmanned owners use gate lockout for the first step and a lock only if needed. Read gate access systems explained and see how gate access in Stitch ties a code to the account.
Mistakes that cause claims
- No lease language. Without it you may have no right to deny access.
- Too early. Locking before your state's minimum day.
- Uneven use. Locking one tenant and not another with the same balance.
- Removing goods. Never take items out outside the lien process.
- Slow to remove the lock. Keeping the lock after payment.
- Telling others. Sharing the debt with neighbors or the tenant's employer.
- No record. Photos and notes are your proof.
Checklist
- Lease allows access denial
- State statute read and your attorney consulted
- Written policy with the lock day
- Tenant message ready
- Lock, photo and note steps defined
- Same-day restoration process
- Lien timeline started
Sample message sequence
Keep these short and calm. Fill in your own amounts, dates and phone number.
| When | Message |
|---|---|
| Day after due date | "Your rent of $95 for unit B12 was due on the 1st. Please pay at [link]." |
| End of grace period | "A late fee of $[fee] was added. Pay $[total] by [date] to avoid restricted access." |
| Day of overlock | "Access to unit B12 is restricted under your rental agreement. Pay $[total] at [link] and access is restored the same day." |
| After payment | "Payment received. Your access is restored. Thank you." |
Never include the contents of the unit, and never send these to anyone but the tenant and the contact they listed.
What to record every time
- Account balance and the date it was due.
- The date and time you placed or removed the lock or turned the code off.
- A photo of the door with the lock on and a photo with it off.
- Every message sent, and any reply.
- Who did it.
Keep these with the account. If a tenant later claims they were locked out wrongly, these records are your answer.
