What is the maintenance logbook?
It is the living file of your building: description of components, maintenance history, work completed and work to plan. Bill 16 makes it an obligation for all divided co-ownerships.
What Bill 16 requires
The logbook must be updated by the board of directors at least once a year, and undergo a review by an authorized person at least every 5 years — or at least every 10 years where the building meets one of the conditions set by the regulation: no more than 8 private portions (excluding those accessory to them, such as storage and parking spaces); no common portion located in a building; no more than 3 storeys entirely above ground. At each establishment or review, the authorized person signs a declaration attesting, among other things, to the on-site examination. For syndicates existing when the regulation entered into force, the first logbook must be established no later than August 15, 2028; other rules may apply to new co-ownerships and promoter transitions.
What Casaforta prepares for you
We assemble the file that makes the logbook possible and useful:
- plans, leases, invoices, warranties;
- inspection reports and maintenance history;
- photos and inventory of components.
We then coordinate the authorized person who reviews and validates the logbook, after which we assist the board of directors with the annual update that is its responsibility, under the written mandate.
What we do not do
We do not sign the regulated logbook when a professional signature is required — that role belongs to the authorized professional we coordinate. Our role is to organize the file and coordinate the next steps defined in the written mandate.
