Inspecting a Category 2 residential building — meaning seven or more private units under section 2.1 of BNQ 3009-500 — is not an automatic extension of inspecting a single-family home. These buildings have systems and obligations the standard frames specifically in Annex D: fire safety, automatic sprinklers, elevators, mechanical systems, and more. For an inspector, it's another league — and that's why REIBH requires a distinct Class 2 certificate, with 180 additional hours of training and two years of post-Class-1 experience.
The framework: why Annex D exists
Annex D is a structured template the inspector asks the owner (or authorized representative of the syndicate or cooperative) to complete before the inspection. It parallels the seller's declaration of Annex F for Category 2 buildings, but goes further: it documents mandatory verification reports required by other codes (notably the National Fire Code) for buildings of this size.
Article 5.3 of the standard requires the inspector to request access to this information. Article 7.1.1 requires taking it into account when gathering objective evidence.
Fire safety (section 1 of Annex D)
For buildings with 9+ units, or 3+ storeys, the Safety Code requires regular verification of several systems. Annex D asks the owner:
1.1 Fire detection and alarm system
- Date of the last verification report
- Does the report indicate necessary corrections?
- Have the necessary corrections been made?
1.2 Automatic sprinkler system
- Date of the last verification report
- Corrections flagged? Completed?
For each, the inspector notes the date of the last verification report and the state of required corrections.
The eight actual sections of Annex D
Here is the exact list of Annex D sections as they appear in the standard:
- Fire safety — detection and alarm system (1.1), automatic sprinklers (1.2)
- Indoor parking garages — mechanical ventilation, verification reports
- Occupant evacuation — emergency lighting, generator (emergency power)
- Façades of buildings 5 storeys or more above grade — mandatory verification report every 5 years by an engineer
- Underground or above-ground parking decks — concrete slabs, structural-integrity verification
- Elevating devices — elevators, freight lifts, personnel lifts (RBQ)
- More stringent provisions of the Safety Code
- Water-cooling tower installation
What Annex D does not directly cover but still forms part of a Category 2 inspection: roof, envelope, main plumbing, electrical installation, common areas. These components are examined under the general rules of chapter 12, with any supplementary information the owner provides.
Elevating devices (section 6 of Annex D)
Elevators, freight lifts, and personnel lifts are governed by specific RBQ rules. Annex D asks:
- Date of the last inspection report
- Device number in the RBQ registry
- State of necessary corrections
The inspector doesn't replace the specialized RBQ inspection — but must document that the reports are current and flag any outstanding corrections.
Façades and parking-deck slabs
Two Annex D sections cover periodic-verification obligations specific to buildings of more than five storeys (section 4) and to concrete-slab parking decks (section 5). The inspector documents the existence and date of these engineering reports — they don't redo the verification themselves.
What sets Category 2 practice apart
Specific training
The Class 2 RBQ certificate requires, in addition to the Class 1 ACS (600 hours), a specialization ACS in large-building inspection of at least 180 hours and two years of post-Class-1 experience. This specialization covers complex mechanical systems, fire safety in large buildings, and common-area management.
We cover the full path in our RBQ building inspector certificate guide.
Higher insurance
Liability scales with building size. The RBQ requires a minimum insurance of $2,000,000 CAD per claim for Class 2 — double the Class 1 requirement.
Inspection duration
A Category 2 inspection typically takes 6 to 15 hours on site, sometimes more for a complex building. Report writing is also longer — often 10 hours or more. We cover this in our guide on pre-purchase inspection duration.
How Axiom³ supports Category 2 inspections
The Axiom³ editor includes a specific template for Category 2 buildings that mirrors Annex D's structure. Each system (fire safety, sprinklers, elevators, HVAC) has its own input block with fields for last-report dates and correction status. The final report integrates this information automatically with explicit reference to Annex D.

Common questions
Can a Class 1 inspector inspect a 7+ unit building?
No, starting October 1, 2027. To accept a mandate on a Category 2 building, the inspector must hold a Class 2 RBQ certificate. Before that date, the rule depends on the transitional framework and the standards of the professional association the inspector belongs to (AIBQ, APCHQ).
What if the owner refuses to provide Annex D information?
The inspector documents the refusal in the report and file (chapter 10). The requester is then informed that certain components could not be assessed due to missing information. That's a documented limit that can also trigger recommendations for additional expertise.
Is Annex D mandatory?
Annex D is informative (not mandatory). But its use flows from article 5.3 (request for available information) and chapter 7 (means of inspection), which are mandatory. An inspector who ignores available information without justification is in breach.
Is a property-owners' cooperative treated as Category 2?
A cooperative is covered by Annex E (supplementary information for cooperatives), which has its own structure. The building may be Category 1 or 2 depending on the number of units — Annex E is added to Annex D for larger co-ops.
