Warehouse Decommissioning Checklist: A Step-by-Step Guide for Facility Managers

Whether you are closing a distribution center, consolidating operations, or handing a warehouse back to the landlord at lease end, decommissioning is a project that punishes poor planning. The building needs to be returned in a specific condition, and the order of operations matters more than most facility managers expect.

This checklist reflects what we have learned decommissioning over 300 commercial and industrial facilities across Ontario and Quebec since 2018.

Phase 1: Pre-Decommissioning (8–12 Weeks Before Vacate Date)

Lease Review and Condition Assessment

Start here. Pull your lease and read the surrender conditions word for word. Most commercial leases in Canada require the tenant to return the premises in "broom-clean" condition with all tenant improvements removed — but the specifics vary significantly.

Key questions to answer before you touch anything:

• Does the lease require removal of all racking, shelving, and fixtures?
• Are you responsible for patching bolt holes in the concrete slab?
• Must you remove mezzanines or demising walls you installed?
• What is the condition of the fire suppression system and who is responsible for recertification?
• Are there any environmental obligations (Phase I or Phase II Environmental Site Assessment)?

If the lease says "restore to original condition," that means every modification you made over the term needs to be undone. A 10-year tenant who installed 500 pallet positions of racking, a mezzanine, and a compressor room is looking at a significant decommissioning scope.

Environmental Assessment

If your operations involved chemicals, petroleum products, solvents, or anything that could contaminate soil or groundwater, you likely need an environmental assessment before the landlord will accept the space back. In Ontario, this is governed by the Environmental Protection Act. In Quebec, the Environment Quality Act applies.

A Phase I Environmental Site Assessment (desktop review and site inspection) costs between $3,500 and $6,000 CAD. If the Phase I identifies concerns, a Phase II (soil and groundwater sampling) runs $8,000 to $25,000 depending on scope.

Do not wait until month 11 of a 12-month notice period to start this process. Phase II assessments take 4–8 weeks for lab results alone.

Phase 2: Asset Disposition (6–8 Weeks Before)

Inventory Everything

Before removing anything, create a complete asset inventory:

• Pallet racking (type, manufacturer, number of bays, beam lengths, upright heights)
• Conveyor systems and material handling equipment
• HVAC modifications (rooftop units, overhead heaters, make-up air units)
• Electrical modifications (sub-panels, dedicated circuits, EV charging)
• Office buildout (furniture, IT infrastructure, cabling)
• Mezzanines and raised platforms

Determine Value vs. Removal Cost

Not everything in a warehouse is waste. Used pallet racking in good condition has resale value — typically 30–50% of new pricing depending on the manufacturer and condition. Teardrop-style racking (the North American standard) holds value better than proprietary European systems.

However, racking that has been damaged, modified, or does not meet current CSA A344 standards may have zero resale value and becomes a removal cost only. Have a qualified racking company assess condition before you assume you will recover money.

Items that typically have resale value:

• Standard teardrop pallet racking in good condition
• Dock levelers and dock equipment less than 10 years old
• Overhead bridge cranes
• Industrial shelving (Rivetier, Metalware)

Items that are almost always removal-cost-only:

• Custom-fabricated racking or mezzanines
• Outdated conveyor systems
• Tenant-installed HVAC (removal cost usually exceeds equipment value)
• Office furniture over 7 years old

Phase 3: Removal and Demolition (3–6 Weeks Before)

Order of Operations

The sequence matters. Getting it wrong creates delays and rework:

1. Data destruction and IT decommissioning — hard drives, servers, network equipment. Get certificates of destruction.
2. Hazardous materials removal — batteries, fluorescent tubes, chemicals, oils. Must be handled by a licensed hazmat contractor with proper waste manifests.
3. Furniture and small equipment — office contents, break room, small tools.
4. Racking and shelving — this is the heavy lift. A 500-position racking system takes a 4-person crew approximately 5–7 days to dismantle and remove.
5. Mezzanine and structural modifications — requires engineering sign-off if load-bearing elements were involved.
6. Mechanical and electrical — remove tenant-installed HVAC, disconnect dedicated electrical circuits, cap plumbing.
7. Slab repair — patch anchor bolt holes, repair damaged concrete, grind down any trip hazards.
8. Final cleaning — broom-clean means different things to different landlords. Industrial sweeping and scrubbing of the entire slab is standard.

Permits and Notifications

Depending on your municipality, you may need permits for:

• Demolition of interior structures (mezzanines, demising walls)
• Electrical disconnection (must be done by a licensed electrician with ESA notification in Ontario)
• Fire suppression system modification (deactivating sprinkler zones requires fire department notification)

Phase 4: Handback (Final Week)

Documentation Package

Prepare the following for the landlord:

• Photographic documentation of the space in its returned condition (every wall, floor section, ceiling, loading dock)
• Environmental clearance documentation (Phase I/II results if applicable)
• Hazardous waste disposal manifests
• Electrical and mechanical sign-offs
• Certificate of fire suppression system status
• Keys, access cards, alarm codes

The Walk-Through

Do a pre-handback walk-through with the landlord's representative 5–7 days before your actual vacate date. This gives you time to address any items they flag before the lease expires.

Common items flagged during walk-throughs that delay deposit returns:

• Unpatched bolt holes in the slab (most common)
• Damage to dock bumpers or dock doors
• Staining on concrete from oil or chemical spills
• Remaining wiring or conduit from tenant installations
• Fire extinguisher or emergency lighting deficiencies

Having photo documentation from your move-in date is invaluable here. If the slab was already cracked when you took possession, you need the photos to prove it. If you do not have move-in photos, you have limited leverage in disputes over pre-existing damage.

Timeline Summary

| Phase | Timing | Key Actions | |-------|--------|-------------| | Pre-Decommissioning | 8–12 weeks | Lease review, environmental assessment, scope definition | | Asset Disposition | 6–8 weeks | Inventory, valuation, buyer identification | | Removal & Demolition | 3–6 weeks | Systematic removal in correct sequence | | Handback | Final week | Documentation, walk-through, key return |

The most common mistake we see is starting too late. A complex decommissioning — one involving racking removal, slab repair, and environmental clearance — needs 12 weeks minimum. Trying to compress that into 4 weeks doubles your cost because everything becomes rush pricing and overtime.
