Multi-unit
inspection.

Buying a condo or income property means buying a share of the entire building. Roof, foundations, common areas, shared mechanical systems — we inspect beyond your unit so no surprises follow you after signing.

Why inspect the whole building

Your unit doesn't
float in mid-air.

Many condo buyers discover after buying that the roof is at end of life, that the common boiler room needs replacing, or that an $8,000 special assessment is on the way. These costs don't hide in your unit — they hide in the common areas.

Foundations & basement

Everything is connected.

A roof at end of life above the 4th floor eventually causes damage in every unit. A poorly maintained common boiler room affects every co-owner's comfort. A foundation crack is shared by the entire building.

Buying in a multi-unit building means becoming co-owner of all these elements — and their costs. A serious inspection has to look at where the money is likely to move.

What is covered

Three inspection levels.
A single report.

Our multi-unit approach combines examining your unit, the interior common areas, and the building's overall envelope — each with its own components and financial stakes.

The target unit
Level 1 · Private. Unit plumbing, fenestration, floors, ceilings, unit electrical, private mechanical installations, signs of moisture or infiltration.
Interior common areas
Level 2 · Communal. Corridors, stairwells, lobby, elevator (visual), common laundry, storage rooms, roof access, general finish.
Enveloppe extérieure
Level 3 · Collective. Roof (membrane, drains, parapets), façades, balconies (corrosion, fasteners), common fenestration, guardrails, shared exterior structures.
Structure & foundations
Examination of accessible basement, foundation condition, structural cracks, perimeter drainage, signs of movement or settling.
Boiler room & mechanical
Common boiler, heat exchangers, distribution, collective ventilation, technical rooms. Remaining useful life estimate for major components.
Main electrical
Main service entrance, general distribution panel, capacity, grounding, visible compliance of collective installation.
Documentary review
When available: declaration of co-ownership, contingency fund, recent meeting minutes, syndicate financial statements, prior technical study reports.
Drainage & waterproofing
Site drainage, accessible French drains, catch basins, roof and balcony stormwater management.
Targeted thermography
On request, thermographic examination of suspect zones — infiltrations, thermal bridges, heat loss in common areas.
The process

Broader than pre-purchase.
Designed for co-ownership.

The multi-unit inspection adds two steps to the classic pre-purchase: coordinating access to common areas and reviewing syndicate documentation.

1
Coordination
Confirming access with the syndicate or manager. Requesting available documents.
2
Preliminary review
Reading received documents before the visit — minutes, contingency fund, prior studies.
3
On-site inspection
3 to 6 hours depending on building size. Unit, common areas, basement, roof (if accessible).
4
Debrief
On-site discussion of findings par niveau : privatif, communautaire, collectif. Vous repartez en sachant.
5
72h report
Report structured by level with priorities and links to items to verify with the syndicate.
Limits and transparency

What co-ownership
honestly complicates.

Multi-unit specifics

The multi-unit inspection has constraints tied to the shared nature of the building. Here's what falls outside our scope:

  • Neighbouring units inaccessible — we don't inspect the interior of other units without explicit occupant authorization
  • No legal analysis — legal interpretation of the co-ownership declaration is for a notary or specialized lawyer
  • Financial documents — auditing the contingency fund and syndicate financial statements is for an accountant, not a building inspector
  • No destructive examination — pas d'ouverture de murs ni de planchers, même dans les parties communes
  • Roof inaccessible — if roof access is locked and no one can open it, we document this limitation in the report
  • Specialized tests separate — radon, air quality and full thermography are additional services
Frequently asked questions

Essential questions
before buying into co-ownership.

Why inspect beyond my unit?

Because you're buying an undivided share of common areas. If the common roof costs $180,000 to replace in two years, your share — say 8% — is $14,400 payable via special assessment. Finding out before signing changes your negotiation. Finding out after is too late.

Will I see the interior of other units?

No, unless the occupant expressly authorizes (rare, and not necessary). We assess other units indirectly through visible signs: moisture at the downstairs neighbour suggesting a leak from the upstairs one, for example.

How do you access common areas?

We coordinate access with the syndicate or building manager. For well-managed co-ownerships, it's a standard procedure. For small self-managed buildings, your realtor or the seller can usually give us direct access.

Is the report useful for my bank or insurer?

Yes. Several Quebec mortgage lenders request an inspection certificate for co-ownerships, especially those over 25 years old. Our report is also admissible for home insurance files and to support renegotiating an offer to purchase.

Combien de temps prend l'inspection ?

De 3 à 6 heures sur place selon la taille de l'immeuble et le nombre d'unités. Un duplex prend 3h. Un condo dans un immeuble de 40 unités peut prendre 5h ou plus. Votre rapport complet vous arrive within 72 hours.

Can you inspect a complete income property (for an investor)?

Absolutely. For duplex, triplex, quadruplex and income plex bought as a block, we inspect every accessible unit plus the entire building. The report is structured to support an investment decision: current state, short/medium/long-term work, impact on net return.

What if the syndicate refuses to provide documents?

It happens — and it's itself a red flag. We document physically accessible elements and explicitly note in the report which documents weren't provided. You leave with an honest read of the situation, including the blind spots.
