Maintenance Logbook: What Every Condo Board Should Know

The maintenance logbook, required under Bill 16, records all work and inspections to help preserve your condo's long-term value.

A Legal Requirement and a Management Tool

The maintenance logbook, also mandated under Bill 16, is far more than an administrative formality: it is your building's technical logbook. It chronologically records completed work, inspections performed, active warranties, and upcoming interventions. A well-kept maintenance logbook in Laval quickly becomes the board's single source of truth.

Without an up-to-date logbook, a syndicate loses its building's institutional memory every time a manager or director changes, which often leads to poorly informed maintenance decisions or redundant work.

What a Compliant Logbook Must Contain

The basic information

The logbook must include building plans and specifications, inspection reports, warranties for major equipment, a history of repairs and renovations, and contact details for the contractors who performed the work.

The link to the contingency fund study

The logbook directly feeds the contingency fund study: professionals rely on its content to validate the actual age of components and adjust replacement projections accordingly.

For the Board: Less Risk, More Transparency

A well-structured logbook makes it easier to report to co-owners at annual meetings, reduces the risk of disputes tied to neglected maintenance, and reassures buyers when a unit goes up for sale. Property managers overseeing commercial or mixed-use buildings benefit from the same principles; an initial commercial building inspection often provides the starting point for a complete logbook right after acquisition.

The Reality Across the Region

South Shore condos, particularly in Longueuil, are seeing rapid growth in conversions and new construction, making it especially important to start a logbook right at delivery. In Laval, several older syndicates need to reconstruct their logbook from scattered documents, an exercise we regularly support.

Common Mistakes to Avoid

Leaving the logbook to one person

When all the information lives in the memory of a single director or manager, their departure can wipe out years of history. The logbook must be designed to survive staff and board turnover, with shared access and backup copies.

Overlooking minor interventions

Boards often document major projects but forget recurring minor repairs, like a repeated plumbing issue or infiltration. Yet it's precisely the recurrence of the same problem that reveals an underlying structural failure that needs priority attention.

How to Structure Your Logbook Effectively

We recommend a centralized digital format, accessible to the board and manager, updated after every intervention, and systematically including photos and invoices. A paper logbook scattered across multiple binders almost always creates blind spots. Check our FAQ for the questions boards ask us most often on this topic.

Finally, plan an annual review of the logbook at the general meeting, to confirm that every intervention from the year has been properly logged and that the attached documents are complete and legible.

The Logbook When a Unit Is Sold

When a co-owner sells their unit, the notary and the buyer typically request a copy of the maintenance logbook as part of due diligence. An incomplete or missing logbook slows down the transaction, raises questions for the buyer, and can even derail a sale if the deadlines set out in the purchase offer aren't met. Conversely, an exemplary logbook becomes a selling point for the whole condo, not just for the unit being sold.

The Logbook During an Insurance Claim

After a loss, such as water damage or a fire, the insurer almost always requests the maintenance history of the affected components to determine whether inadequate maintenance contributed to the loss. A well-documented logbook speeds up claim processing and can make the difference between a full payout and a partial denial citing the syndicate's negligence.
