Commercial building inspection in
Montreal

Whether you are a commercial property owner, buyer or investor, seller, property manager, or preparing for work or fit-up, a commercial building inspection helps you better understand the apparent, visible and accessible condition of a commercial, industrial, multi-residential (5+ units) or mixed-use building. Envelope, roof, visible structure, plumbing, electrical, heating / ventilation / HVAC visible elements, observable user safety, and indications of wear or moisture are observed to provide a clear picture of the overall apparent condition of the building. The goal: identify items to monitor, prioritize necessary follow-ups and specialized verifications, and help you make informed decisions about purchase, management, investment or planned work.

InterNACHI Certified · Insured · Detailed Professional Report

Scope of our commercial inspection The inspection is visual and non-invasive. It documents the visible and accessible condition of the building at the time of the visit, according to the agreement and available access. It does not replace engineering expertise, contractor estimates, environmental studies, real estate appraisal, financial analysis, legal advice or specialized regulatory verification.
Inspection categories

What types of properties are considered
commercial or multi-unit?

At Inspecteur Élite, commercial inspection covers properties used for commercial, professional, industrial, mixed-use or larger multi-unit purposes. This includes retail units, offices, clinics, restaurants, warehouses, garages, light-industrial buildings, commercial condos, mixed-use buildings with a storefront or business occupancy, and 5+ unit multi-residential buildings.

✓ Plexes and small income properties — duplexes, triplexes and fourplexes. Handled as residential / multi-unit inspection. See our multi-unit inspection.
✓ 5+ unit multi-residential buildings. Treated as commercial / multi-unit inspection because the scope, systems, access, risk profile and due-diligence level are different.
✓ Mixed-use buildings with a non-residential component. A building with a store, office, clinic or restaurant at street level and apartments above — handled as a commercial / mixed-use inspection.
✓ Non-residential uses — retail, office, restaurant, clinic, warehouse, garage, light industrial, commercial condo. Handled as commercial inspection.

Note: this is our inspection-scope categorization. The legal, tax or municipal commercial/residential classification can depend on actual use, municipal zoning, the assessment roll, financing, insurance and the presence of mixed occupancy. For formal compliance questions, consult the appropriate professionals (chartered appraiser, municipal inspector, legal advisor).

Better understand your commercial building

A commercial inspection for owners, investors and property managers

A commercial building inspection can be useful well beyond buying or selling. It can help a commercial property owner or property manager better understand the apparent, visible and accessible condition of the building, plan work or fit-up (tenant renovations, envelope upgrades, roofing, mechanical), prioritize maintenance and budget planning, or document visible warning signs such as moisture, cracks, water intrusion or deterioration.

Scope: a commercial inspection remains a visual review of the building and its accessible components. Specialized assessments such as environmental characterization, engineering analysis, regulatory verification, financial analysis, or legal advice require dedicated expertise.

Who this is for

A commercial building inspection
fits several profiles.

A commercial building inspection documents the apparent, visible and accessible condition of a commercial, industrial, multi-residential (5+ units) or mixed-use building at the time of the visit. It serves anyone who wants to better understand the overall apparent condition of the building — whatever the context. For residential plexes (2 to 4 units), see our plex inspection.

🏢
Commercial property owner
You own a commercial, industrial, multi-residential or mixed-use building and want to better understand its apparent condition, plan necessary follow-ups, and prioritize maintenance.
For the commercial property owner, the inspection provides a clear picture of the overall apparent condition of the building: envelope, roof, visible structure, accessible mechanical systems (HVAC, plumbing, electrical), observable user safety, and indications of wear or moisture. The report documents items to monitor with photos and priority levels, and points toward a recurring preventive inspection when relevant.
🔑
Buyer or investor
You are evaluating a commercial building before purchase — for owner-occupied use, leasing, or as an investment. For the transaction context (inspection condition, short timelines), see also our dedicated service.
For the buyer or investor, see our dedicated service pre-purchase inspection when the transaction context calls for it. The inspection documents the apparent condition of the building, accessible systems, and items that may require specialized verification. Scope: a visual review of the building — it does not replace environmental characterization, engineering analysis, specialized regulatory verification, financial analysis, or legal advice.
📋
Seller
You are preparing to list your commercial building. A prior inspection helps identify items to correct or disclose, and limits surprises during negotiation.
For the commercial seller, see our pre-sale inspection service for listing preparation: prior picture of the building's apparent condition, documentation useful for disclosure, and support during negotiation with a potential buyer.
🏗
Property manager
You manage a portfolio of commercial buildings and want a clear picture of a building's apparent condition to plan maintenance and anticipate work.
For the property manager, the inspection produces a structured picture of the building's overall apparent condition: envelope, roof, visible structure, HVAC, plumbing, electrical, observable safety elements. The report orients long-term maintenance planning and prioritization of follow-ups. See also our preventive inspection service for recurring follow-up.
🛠️
Before work or fit-up
You are planning work or fit-up (tenant renovations, envelope upgrades, roofing, mechanical). The inspection establishes a prior picture of the visible components involved.
Before commercial work or fit-up, the inspection documents the apparent condition of the components concerned and connected elements likely to be affected (envelope, visible structure, HVAC, plumbing, electrical). This helps better prepare contractor bids, sequence the work, and anticipate necessary specialized coordination (engineer, environmental professional, municipal inspector as the mandate requires).
📅
Budget planning and maintenance
You want to budget maintenance for the next 3, 5 or 10 years on a concrete basis. The inspection produces a list of items to monitor with priority levels.
The inspection produces a structured report with photos and priority levels, useful as a long-term budget planning and maintenance tool: components nearing end of useful life to anticipate (roof, HVAC, envelope, plumbing, mechanical), items to monitor annually, specialized follow-ups to plan. See also our preventive inspection service structured for recurring follow-up.
Why a commercial inspection

The stakes are higher.
The inspection should be too.

A commercial building represents an important commitment. Mechanical systems, observable safety elements and apparent structural condition may influence planning, specialist verifications and maintenance priorities. Our visual inspection gives you the information you need to evaluate commercial properties in Montreal and move forward with confidence.

What every buyer should know

The realities of commercial
buildings in Montreal.

A commercial building has different challenges than a residential property. Here are the critical points our inspection covers.

Commercial HVAC systems Commercial buildings use high-capacity heating, ventilation and air conditioning systems — rooftop units, boilers, forced-air systems, chillers. These systems can be complex to replace; their apparent condition helps identify specialist verifications and maintenance priorities.
Observable safety elements (visual review) Commercial buildings often have several observable safety elements such as visible systems, centralized alarms, emergency lighting and emergency exits. Our role is visual identification of these observable elements and apparent indicators; specialist verification may be recommended when applicable.
Commercial roofing Commercial roofs are typically flat membrane systems. They often support mechanical equipment (rooftop units, fans, ducts). Membrane condition, drainage, flashing around penetrations and ponding water are important indicators to document.
Electrical service entrance Commercial buildings often require high-capacity electrical service. The condition of the main panel, distribution, visible wiring and apparent remaining capacity are elements we observe and may refer for specialist verification.
Observable accessibility elements Commercial buildings may have visible access elements such as ramps, elevators, automatic doors, accessible washrooms and reserved parking. We identify these elements visually; formal verification by a qualified professional may be appropriate when needed.
Buildings with 5 or more units At Inspecteur Élite, once a building has 5 or more units the file is handled as commercial / multi-unit inspection because the scope, shared systems, access, risk profile and due-diligence level are different. Our inspection observes accessible units and visible shared systems; formal verification by a qualified professional may be appropriate. If your condo association needs a focused evaluation of shared spaces, see our common area inspection.

Frequently asked questions about
commercial inspections.

Everything you need to know before booking your commercial building inspection in Montreal.

What types of commercial buildings do you inspect?+
We inspect all types of commercial buildings: offices, retail stores, restaurants, warehouses, light industrial buildings, clinics and mixed-use properties. Each inspection is tailored to the specific purpose of the building.
How does a commercial inspection differ from a residential inspection?+
Commercial inspections cover elements specific to non-residential buildings: commercial HVAC systems, observable safety elements, apparent structural-load indicators and industrial ventilation systems. Formal commercial regulatory verification is the role of a licensed professional.
How much does a commercial inspection cost in Montreal?+
The rate is custom-quoted based on floor area, building type, number of floors, mechanical system complexity and inspection scope required. Contact us for a free, no-obligation quote. See our detailed pricing for context on residential services.
Does the inspection include an environmental assessment?+
Our standard inspection identifies visual signs of potential issues such as apparent asbestos, visible mold or observable underground tank presence. For a complete Phase 1 environmental assessment, we can refer you to our specialized partners.
How long does a commercial inspection take?+
Duration varies significantly based on building size and complexity. Expect half a day for a small commercial space, up to several days for a large building. The professional report is delivered within 48 to 72 hours following the inspection.
Why is a 5+ unit building treated as commercial inspection?+
At Inspecteur Élite, once a building has 5 or more units the file is handled as a commercial / multi-unit inspection because the scope, systems, access, risk profile and due-diligence level are different. Our visual inspection observes accessible elements; formal regulatory verification is the role of a licensed professional. The legal, tax or municipal commercial/residential classification can also depend on actual use, municipal zoning, the assessment roll, financing, insurance and the presence of mixed occupancy.
What does the report actually give me after the inspection?+
The report documents every system and accessible zone of the building with photos, priority level and recommendations. It helps clarify maintenance priorities and planning after acquisition.
Do you inspect revenue properties with 5 or more units?+
Yes. Revenue properties with 5 or more units fall under our commercial / multi-unit inspection service. Accessible units according to the agreement are inspected visually, along with visible shared systems. Observable elements are documented; formal regulatory verification is the role of a licensed professional. For plexes and small income properties (duplexes, triplexes and fourplexes), see our multi-unit inspection.
Does a commercial inspection replace engineering expertise?+
No. A commercial inspection is a visual evaluation of accessible components. When an issue is beyond the scope of a visual inspection, specialist verification may be recommended.
Is a commercial inspection useful before buying a building?+
Yes. It helps clarify the visible condition of the building, systems to monitor, observed deficiencies and specialist verifications to consider before an important decision.
Does the report include repair costs?+
The report can help identify priorities and types of work to expect, but it does not replace a contractor estimate, budget analysis or specialized financial evaluation.
What types of commercial buildings do you inspect?+
Our commercial inspection covers: office buildings, retail spaces and stores, restaurants and bars, warehouses and light industrial buildings, medical and dental clinics, schools and private daycares, shopping centres (individual sections), mixed-use buildings (commercial-residential), 5+ unit multi-residential buildings (commercial multi-unit category), institutional buildings. For heavy industrial buildings, additional specialised expertise may be required.
What is the difference between commercial inspection and Phase I/II environmental assessment?+
Commercial inspection evaluates the building's physical condition: structure, envelope, roofing, mechanicals (HVAC), electrical, plumbing, fire safety, accessibility. Phase I Environmental Site Assessment is a documentary evaluation of site contamination risks (use history, industrial neighbours, tanks). Phase II involves soil/water sampling and analysis. The two are distinct and complementary — our commercial inspection documents visible environmental indicators (stains, tanks, suspect conduits), but Phase I/II assessments fall under qualified environmental consultants (firms like Golder, GHD, etc.).
Does commercial inspection include HVAC, sprinklers and elevators?+
Our commercial inspection covers visual evaluation of systems: HVAC (heating, ventilation, air conditioning — boilers, rooftop units, visible ducting, thermostats), commercial plumbing (supply, drains, industrial water heaters), commercial electrical (service entrance, panels, capacity), sprinklers and fire alarm (presence and visible indicators — no functional testing), elevators and freight lifts (presence and apparent condition — mandatory annual inspection falls under a specialised elevator maintenance firm). For detailed capacity or compliance evaluation, separate specialised expertise required.
What are the specifics for commercial buildings on former industrial land?+
Several Montreal areas (Hochelaga-Maisonneuve, Pointe-Saint-Charles, Saint-Henri, Pointe-aux-Trembles, Saint-Léonard, Saint-Michel) have industrial history. For commercial buildings in these sectors: we document visible indicators of potential contamination (stains, visible tanks, old industrial piping, residual conduits), systematically recommend Phase I Environmental Site Assessment by qualified firm, verify the concrete slab (cracks, heaving indicating possible soil contamination), and document applicable regulatory verifications (HWMA, municipal requirements).
How long does a commercial inspection take and what report format?+
Duration varies widely with size and complexity: retail space < 2,000 sq ft: 3-4 hours, commercial building 2,000-10,000 sq ft: 5-8 hours (often 1-2 days), commercial building 10,000+ sq ft: 1-3 days, 5-20 unit multi-residential: 1-2 days. The commercial report is more detailed: executive summary, system-by-system evaluation, findings matrix with priorities (immediate / 1 year / 5 years), recommendations for additional expertise, detailed photography. Report within 24-72h* depending on complexity.
Is a commercial building inspection useful even if I am not buying?+
Yes. A commercial building inspection also serves the commercial property owner, the property manager, those preparing for work or fit-up, a seller preparing to list, or any organization that has noticed visible warning signs (moisture, cracks, water intrusion, envelope deterioration). The inspection remains a visual review of the building — it does not replace specialized assessments (environmental, engineering, specialized regulatory verification, financial or legal analysis). For an active purchase, see also pre-purchase inspection; for a long-term owner or manager, see also preventive inspection.
Should I inspect a commercial building before work or fit-up?+
Yes. Before work or fit-up (tenant renovations, commercial fit-up, envelope upgrades, roofing, mechanical, HVAC), an inspection documents the apparent, visible and accessible condition of the components concerned and connected elements likely to be affected (envelope, visible structure, plumbing, electrical, mechanical). This helps better prepare contractor bids, sequence the work, anticipate necessary specialized coordination (engineer, environmental professional, municipal inspector). See also preventive inspection for longer-term maintenance planning.
What visible signs should trigger a commercial building inspection?+
Several visible warning signs justify a commercial building inspection: moisture or staining at ceilings or walls, apparent structural cracks, infiltrations through the roof or openings, envelope deterioration (cladding, joints, sealants), HVAC or ventilation issues, visible wear on mechanical systems. The inspection documents these signs with photos and orients toward appropriate specialized verifications as needed (thermography for hidden infiltration, mold and air quality analysis, engineering expertise for structural concerns).
