A photo of a broken towel bar or stained sofa can document visible damage, but it may not show whether the condition is new. A reviewer may also need prior-condition records, responsibility information, ownership documents, and cost support.
A current baseline gives later walkthroughs a comparison reference. It can help show that visible condition changed between records, but it does not independently establish who caused the change or whether it is covered.
This article focuses on one useful part of that record: a baseline. It provides a recorded comparison reference, while the claim still depends on the applicable terms, timeline, responsibility information, ownership records, and cost support.
The Prior-Condition Question
Put yourself in the reviewer's chair for a moment. A host submits a claim: photos of a scratched dining table, a repair estimate, a description of the guest's stay. The guest responds that the scratch was already there when they checked in. The reviewer now has two contradictory stories and one photo that is consistent with both of them.
Airbnb's Host Damage Protection Terms, last updated August 1, 2026, require timely notice and supporting documentation. Other documents, deadlines, exclusions, and decisions still apply. For separate general context, Nolo's small-claims guide discusses evidence used to show property damage and responsibility in small-claims disputes. A baseline can support prior-condition review, but TurnAudit does not decide responsibility, coverage, or approval.
A damage photo and a baseline answer different questions. The damage photo records a later condition; the baseline provides an earlier comparison reference.
What a Baseline Actually Is
A baseline is a room-by-room visual record of the property in its intended state. It does not capture every surface or detail, and its value depends on recency, camera coverage, image quality, and accurate property context.
A continuous walkthrough can provide more spatial context than isolated photos. It still records only what enters the camera view and does not independently establish when, where, or by whom the scene was recorded.
Three practices make a baseline more useful as an earlier comparison reference:
- Its context is documented. Record when the reference was made and what property state it was intended to show. An application date is not an independent RFC-3161 timestamp and does not establish recording time.
- The source reference is not edited. Avoid filters, enhancement, trimming, and re-exporting. The baseline remains a comparison reference and does not receive the turnover evidence pipeline's WORM or RFC-3161 controls.
- Its coverage is intentional. Record every listed room and important area, while recognizing that no walkthrough guarantees complete visual coverage.
Why a Current Baseline Adds Useful Context
A later photo can document a current condition, and a later estimate can document cost. Neither can recreate a visual record of the property before the stay. A baseline must be recorded while it can still serve as a prior-condition reference.
A baseline can make a later-condition comparison easier to review. It does not make a claim pass, confirm the recording date, or establish who occupied or damaged the property; those facts require other records.
A baseline preserves visible prior-condition context that cannot be recreated after a disputed condition is discovered.
When two records show different visible conditions, a reviewer has comparison material rather than only competing descriptions. The reviewer still decides what the records establish and whether other requirements are met.
From Baseline to a Narrower Comparison Window
A baseline documents visible condition in one recording. If it is six months old, the condition could have changed during any intervening stay. More frequent records can narrow the comparison interval without establishing cause.
This is where the baseline connects to turnover documentation. A pre-clean walkthrough records visible condition after checkout and before cleaning. A post-clean walkthrough records visible condition after cleaning. Together with reservation and communication records, they provide context for a reviewer:
- Baseline: the recorded view shows the item's visible condition in the property's reference state.
- Previous turnover's post-clean record: the recorded view may show the item's visible condition after the prior cleaning. It does not independently establish the exact check-in state.
- This turnover's pre-clean record: the recorded view may show visible damage after checkout and before cleaning. It does not independently establish guest responsibility.
No recording or sequence independently verifies causation. The baseline is a comparison reference, while reservation, communication, ownership, cost, and other records may address different claim requirements. See our damage claim documentation guide for the broader package.
Uploaded-File Integrity and Timestamp Material
For eligible pre-clean and post-clean turnover uploads, provenance controls can verify the integrity of the uploaded original and its upload chronology. They do not independently show when or where the recording was made, who recorded it, or whether the scene is complete or authentic. A baseline is stored as a comparison reference under a different lifecycle.
Airbnb's Host Damage Protection Terms, last updated August 1, 2026, require claim evidence to be true, accurate, and not doctored or falsified, including by AI. For eligible turnover uploads, TurnAudit preserves the uploaded original, computes its SHA-256 digest from stored bytes, and reports RFC-3161 timestamp status. These controls do not guarantee the package meets every Airbnb requirement or will be approved. Our integrity explainer covers the mechanics and limits.
Treat the baseline recording as a source reference. Avoid editing, filtering, trimming, or enhancing it. If you create an annotated copy, keep it clearly separate from the source reference. TurnAudit does not independently establish the baseline's recording time or capture circumstances.
A Stale Baseline Is a Weak Baseline
A baseline documents a moment, and properties change. New furniture, decor, flooring, or finishes can make an older baseline less useful for comparing a specific item or area.
Re-record the baseline whenever something meaningful changes, and consider periodic refreshes. Baseline reference recordings are retained while the account is active. They are not the same as locked Tier 1 turnover originals and do not receive the same RFC-3161 verification package.
What a Baseline Cannot Do
A baseline does not guarantee a claim outcome. It does not distinguish guest-caused damage from wear and tear, establish recording time, or replace prompt reporting, ownership records, cost documents, and other materials required by the applicable terms.
When software compares a walkthrough against a baseline and flags a possible issue, that flag is advisory: a prompt for human review, not evidence or a decision. Tier 1 contains the uploaded original and its verification material. The host decides what to submit, and the reviewer decides what it establishes.

How to Record a Useful Baseline
If you take one action after reading this, record your baseline. Here is how to do it well:
- Stage the property in its known-good state. The baseline should show the property exactly as a guest is meant to receive it: clean, furnished, everything in place.
- Record one continuous walkthrough per room. Move slowly, keep steady, and record 15 to 45 seconds per room, aiming for 20 to 30 seconds. Rushed footage produces blurry frames that are useless for comparison later.
- Cover the unglamorous spots. Include areas such as behind doors, under windows, closet interiors, appliance fronts, headboards, and table legs.
- Know the baseline lifecycle. Baseline references are kept while the account is active. They are not locked Tier 1 turnover originals and do not carry the same RFC-3161 verification material.
- Re-record when the property changes. A baseline that no longer matches the property is a gap in your record. Make refreshing it part of any furnishing or renovation project.
TurnAudit's baseline recording provides a guided comparison reference for later walkthroughs. It is stored as a baseline reference, not as a locked Tier 1 turnover original. The host still decides what to submit, and the reviewer decides what the record establishes.
