Overview
This worksheet is for semi-annual audits of a law enforcement evidence room or property room. It guides the reviewer through a controlled inventory reconciliation, then checks chain-of-custody records, storage segregation, room security, and fire-life-safety conditions in the same order an evidence custodian would actually verify them.
Use it when you need to confirm that physical evidence matches the master log by case number or unique identifier, that seals and transfer records are intact, and that the room itself is still suitable for secure storage. It is especially useful after staffing changes, a move, a security event, or any period where evidence handling volume has increased and record drift is more likely.
Do not use this as a casual spot-check or as a substitute for a full agency policy review. If your audit only needs a quick count of a few shelves, a shorter inventory log may be enough. If the room is under active investigation, sealed for a criminal matter, or subject to a legal hold with restricted access, follow the applicable command, prosecutor, or court instructions before opening containers or moving items. The template is designed to document what was inspected, what matched, what did not, and what needs follow-up without losing chain-of-custody discipline.
Standards & compliance context
- The worksheet supports the documentation and control expectations commonly used in law enforcement evidence handling and chain-of-custody procedures.
- Its fire, exit, and housekeeping checks align with general workplace safety principles reflected in OSHA standards and NFPA fire-life-safety codes.
- Storage segregation and environmental control fields help document handling practices for wet, biological, hazardous, and sensitive evidence in line with agency procedures and applicable public-safety guidance.
- If your agency follows accreditation or quality management practices, the audit trail also supports corrective action tracking and repeatability consistent with ISO-style record control.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Audit Scope and Inventory Setup
This section establishes the audit period, location, source inventory, and count method so the review starts with clear boundaries and controlled handling.
- Audit period documented as semi-annual and room/location identified
- Current evidence inventory report or master log available for reconciliation
- Inventory count method defined before opening containers or shelves
- Two-person control or witness present for audit activities
- Audit start date and time recorded
Physical Inventory Reconciliation
This section is the core count, where each physical item is matched to the record and every shortage, overage, or misfiled item is captured.
- Items counted match the inventory record by case number or unique identifier
- Shortages identified and documented
- Overages identified and documented
- Misfiled, mislocated, or cross-shelved items identified
- Items with record discrepancies flagged for follow-up
Chain-of-Custody and Seal Integrity
This section verifies that sampled evidence can be traced from intake to current storage without unexplained breaks or tampering.
- Evidence seals intact and free of tampering
- Chain-of-custody documentation complete for sampled items
- Transfers, releases, or returns are signed, dated, and traceable
- Any evidence item with a custody break or unexplained gap identified
Storage Conditions and Evidence Handling
This section checks whether evidence is segregated, labeled, and protected according to its handling needs and condition class.
- Wet, biological, hazardous, and dry evidence segregated per procedure
- Shelving, bins, and containers labeled with unique location identifiers
- Damaged packaging, leaking containers, or compromised evidence observed
- Evidence requiring special storage conditions is properly controlled
Security, Access Control, and Room Condition
This section confirms that only authorized personnel can enter and that the room itself is secure, orderly, and safe to access.
- Access is restricted to authorized personnel only
- Door, lock, alarm, and camera controls functioning as intended
- No signs of unauthorized entry, forced access, or security breach
- Housekeeping, lighting, and aisle clearance adequate for safe access
Fire, Life-Safety, and Environmental Controls
This section documents the room’s readiness for fire response, safe egress, and stable environmental storage conditions.
- Fire extinguisher present, accessible, and inspection tag current
- Emergency exit path clear and unobstructed
- Temperature and humidity within agency storage limits
- Any fire, water intrusion, pest, or environmental deficiency observed
How to use this template
- 1. Enter the audit period, room location, start date and time, and the current inventory report or master log before any containers or shelves are opened.
- 2. Assign two-person control by naming the primary auditor and witness, then define the count method so the team knows whether it will be a full count, sample count, or shelf-by-shelf reconciliation.
- 3. Walk the room in order, compare each physical item to the inventory record by case number or unique identifier, and record shortages, overages, misfiled items, and discrepancies as you find them.
- 4. Sample evidence items for chain-of-custody review, checking seals, transfer signatures, dates, and any unexplained custody gaps, then flag any item that cannot be traced cleanly.
- 5. Inspect storage conditions, security controls, and environmental protections, documenting segregation, labeling, damaged packaging, access restrictions, camera or alarm issues, and fire or water-related deficiencies.
- 6. Close the audit by assigning corrective actions, owners, and due dates for each deficiency, then retain the completed worksheet with the audit record and any supporting photos or notes.
Best practices
- Count from the inventory report to the shelf, not from memory, so every item is reconciled against a documented source.
- Photograph shortages, broken seals, damaged packaging, and misfiled evidence at the time of discovery so the audit record supports follow-up.
- Keep wet, biological, hazardous, and dry evidence segregated during the review and note any cross-storage condition as a deficiency.
- Verify that each sampled item has a complete custody trail before you move to the next shelf, because later reconstruction is harder and less reliable.
- Treat a missing signature, date, or unexplained transfer gap as a record discrepancy until it is resolved by supporting documentation.
- Check that the room’s lock, alarm, and camera coverage are functioning before you rely on the audit as proof of secure storage.
- Record corrective actions in plain language with an owner and due date so the next semi-annual audit can verify closure.

Common use cases
Frequently asked questions
What does this evidence room audit template cover?
It covers the full semi-annual walk-through of an evidence room, starting with the inventory report and ending with fire, life-safety, and environmental checks. The worksheet is built to reconcile physical items against the master log, confirm chain-of-custody integrity, and record storage or security deficiencies. It is meant for law enforcement property and evidence operations, not for general office inventory.
How often should this audit be run?
The template is structured for a semi-annual cadence, which is common for formal evidence room reviews and supervisory inventory checks. You can also use it after a staffing change, room relocation, security incident, or major case surge. If your agency policy requires a different interval, the worksheet can be edited without changing the audit flow.
Who should perform the audit?
A property and evidence supervisor, evidence technician, or other designated custodian should lead it, with a second person present for two-person control or witness verification. That second person helps preserve audit integrity and reduces the risk of missed discrepancies. If your agency uses internal affairs, a records auditor, or command staff for oversight, they can be added as reviewers.
Does this template align with legal or regulatory expectations?
Yes, it supports the documentation discipline expected under law enforcement evidence handling policies and broader chain-of-custody practices. It also aligns well with general safety and storage expectations drawn from OSHA workplace safety principles, NFPA fire-life-safety concepts, and agency evidence retention procedures. It is not a substitute for your department policy, prosecutor requirements, or local court rules.
What are the most common mistakes this audit catches?
Common findings include items that do not match the inventory record, misfiled evidence on the wrong shelf, broken seals, incomplete transfer signatures, and evidence stored in the wrong condition category. The worksheet also surfaces access-control issues such as a malfunctioning lock, camera gap, or unsecured room. Those are the kinds of problems that can affect admissibility, accountability, and safety.
Can I customize the worksheet for narcotics, firearms, or biological evidence?
Yes, and you should. Add location-specific fields, special handling notes, and any agency-required controls for firearms, controlled substances, wet evidence, or biohazard items. The existing sections already support segregation, special storage, and custody review, so you can tailor the checklist without changing the core audit logic.
How does this compare with an ad hoc evidence room check?
An ad hoc check often finds obvious issues but misses traceability, repeatability, and follow-up tracking. This template forces the audit to follow a consistent sequence: scope, reconciliation, custody, storage, security, and environmental controls. That makes it easier to compare one semi-annual review to the next and prove what was inspected.
Can this worksheet be used with digital inventory systems or barcode scans?
Yes. Use the master log or inventory report as the source of truth, then record scanned counts, discrepancies, and follow-up actions in the worksheet. If your system supports case numbers, unique identifiers, or location codes, those fields can be mirrored in the template to speed reconciliation and reduce transcription errors.
What should I do if I find a custody break or missing item?
Document the discrepancy immediately, preserve the item location, and escalate according to agency procedure. Do not overwrite the record or try to reconcile a gap without supporting documentation. The worksheet is designed to flag the issue clearly so supervisors can open a follow-up review, incident report, or corrective action process.
