Access Logs: Knowing Who Has Entered a Claremont Home

Smart locks record every entry. How to structure codes so the log stays readable during showings and renovations, and what happens to it at closing.

The lock is the boring half of a smart lock. The interesting half is the LOG.

Every code entered, every app unlock, every auto-lock event, stamped with a time and, if you set it up properly, a NAME. That record is the reason smart locks belong on a vacant house, a house under renovation and a house being shown. Those are three situations Claremont homeowners land in constantly, and three situations where a mechanical key tells you exactly nothing about what happened while you were gone.

This piece is about the log itself: what it captures, what it quietly fails to capture, how to structure codes so the record is actually readable, and what happens to two years of entry history when the house changes hands. It builds on the smart-home guide and assumes you have already worked through smart locks and showings, which covers the hardware side.

One code per person. Never a shared code.

This is the single decision that determines whether the log is useful or useless, and most people get it wrong on day one by picking a household code and giving it to everybody.

A shared code produces a log that says the front door was unlocked at 2:14 in the afternoon. Twelve times. That is a timestamp, not information. INDIVIDUAL codes produce cleaner at 2:14, painter at 8:02, dog walker at 11:30, which is a record you can actually reason about.

The discipline that follows:

  • NAME EVERY CODE at the moment you create it. Code Four means nothing six months later. Most locks let you label a slot, so use it.
  • ONE CODE PER PERSON OR PER TRADE, not per household and not per week.
  • SET AN EXPIRY where the platform supports it. A contractor code that dies on the last day of the job cannot be reused in November.
  • DELETE CODES WHEN THE RELATIONSHIP ENDS. The most common failure in the category is a live code belonging to someone who stopped working at the house eighteen months ago.
  • AUDIT THE LIST QUARTERLY. Open the code list, read every name, delete anything you cannot immediately explain. It takes two minutes.

What the log does not know

Be clear-eyed about the limits, because people over-trust this record.

A LOG RECORDS THE LOCK, NOT THE HOUSE. Someone who entered through an unlocked slider, a detached garage side door or a window generates no entry at all. Older Claremont houses tend to have more doors than the owner thinks about: a kitchen door to the side yard, a garage that connects, a laundry porch. The log covers the doors you instrumented and nothing else.

A LOG RECORDS A CREDENTIAL, NOT A PERSON. It says the cleaner code was used. It does not say the cleaner used it. Codes get shared, written on a clipboard and passed to a substitute without anyone telling you.

A LOG DOES NOT ALWAYS RECORD DEPARTURE. Auto-lock events and manual locks are different entries; know which your device writes down.

RETENTION IS FINITE AND PLATFORM-DEPENDENT. Some systems keep a long history, some keep a short rolling window, and some put deeper history behind a subscription. If the record matters to you, find out how far back yours actually goes BEFORE you need it. This is the same fragility that hits every cloud-dependent device, and it is a good argument for the platform thinking in when the app outlives its company.

The three situations where this earns its keep

DURING SHOWINGS. Agent access, contractor access and inspector access all land in the same window, and a per-visitor record answers the questions that come up afterward: who was here, when, how long between unlock and re-lock. Note the boundary firmly. A log is an ENTRY record, not surveillance. Interior cameras and microphones during showings are an entirely different question governed by California two-party audio consent, and the answer there remains disclose or disarm. Do not let a comfortable access log become an excuse to leave a microphone running while buyers talk about your price.

DURING RENOVATION. Multiple trades, overlapping schedules and a house full of materials. Per-trade codes with expiry dates turn a chaotic month into a readable timeline, and they end the awkward conversation about who still has a key.

DURING VACANCY. An inherited property, a house between tenants, a home whose owner is in a care setting. The log is often the only evidence anyone is checking on the place at all, and its absence is evidence too.

Tenants, and the line you do not cross

If the property is rented, the log is a landlord-side record of the landlord's own access, not a monitoring tool for the tenant's comings and goings. A tenant's entry pattern is their private life. Keeping an owner code for legitimate noticed access is normal; treating an occupied unit's log as a behavioral record is not, and it interacts badly with California requirements for notice before entry. The tenant-side boundaries are worked through in smart devices in a Claremont rental. This is general information rather than legal advice.

At closing, the log leaves with the seller

Two years of entry history is a record of who came and went from a house that is no longer yours. It should not be handed to a buyer, and the buyer should not be inheriting your account.

The correct sequence is the same as every other connected device: DELETE EVERY CODE, factory reset the lock, remove it from your account, and let the buyer enroll it fresh under their own credentials. A lock that still carries the seller app access is a working key in a stranger's hand, and a lock still holding the seller code list is a set of live credentials nobody has audited. Both are fixed by one reset, and that step belongs on the same checklist as the rest of the handover.

On the buying side, the question to ask at possession is simply whether the lock has been reset and whether you can see the code list. If the answer is unclear, reset it yourself on day one. It costs nothing and it is the only way to know.

The short version

One code per person, named at creation. Expire what is temporary. Delete what is finished. Audit quarterly. Know how far back your history goes. Do not mistake an entry record for full coverage of the house, and do not let it drift into surveillance of tenants or of buyers walking through with their agent.

The hub above is the starting point, and the hardware decisions live in the smart locks and showings guide. Anthony Grynchal has been licensed in California since November 2009.

Frequently asked questions

What does a smart lock access log actually record?

Each unlock event with a timestamp and, if you set it up properly, the name of the code used. It covers the doors you have instrumented and nothing else, and it records the credential rather than the human, so a shared code produces a log you cannot reason about. One named code per person is what makes the record useful.

How long is smart lock history kept?

It varies by platform. Some systems put deeper history behind a subscription while others keep only a short rolling window. Find out how far back yours goes before you need it rather than after. If the record genuinely matters for a rental or a renovation, that retention window should influence which system you choose.

Can I use an access log to monitor a tenant?

No. A landlord log is a record of the landlord side of access, not a behavioral record of the occupant. Treating an occupied unit that way interacts badly with California entry-notice requirements and with basic tenant privacy. Keep an owner code for legitimate noticed access and leave the tenant record alone. This is general information, not legal advice.

Does an access log let me skip disclosing cameras during showings?

No, and the two are separate questions. An entry log is a record of who unlocked a door. Cameras and microphones inside a listed home are governed by different rules, including California two-party consent for audio, and the standard there remains disclose or disarm before buyers walk through.

What should happen to a smart lock at closing?

Delete every code, factory reset the lock, and remove it from the seller account so the buyer enrolls it fresh. A lock left on the seller account is a working key in someone elses hand, and an un-audited code list is a set of live credentials. Buyers who are unsure should simply reset it themselves on day one.
