Since coming into effect, Bill 16 has transformed the way condominiums are managed in Quebec. Adopted to ensure the longevity of buildings and protect the value of investments, it now imposes new responsibilities on both syndicates and co-owners.

Here’s a summary of the main requirements to know.


1. The Building Maintenance Logbook

Every condominium syndicate is now required to keep an up-to-date maintenance logbook. This document lists all completed work, preventive maintenance to be performed, and upcoming interventions on the building’s common components (roof, siding, heating system, etc.). The goal: to promote planned management rather than reactive management, and to avoid unpleasant surprises.


2. The Reserve Fund Study

Bill 16 makes it mandatory to conduct a reserve fund study by a qualified professional (engineer, architect, or technologist).

This study determines the actual amount the condominium must set aside to fund major repairs and the replacement of common elements over the long term. Contributions to the fund must be adjusted accordingly, ensuring better financial health for the syndicate.


The maintenance logbook and reserve fund study are not static documents. They must be reviewed periodically, especially after major work is completed or when a building component is replaced. This ensures that the syndicate’s decisions are always based on current and reliable information.


3. The Syndicate’s Certificate in the Event of a Sale

When a co-owner sells their property, the syndicate must provide a certificate confirming, among other things:

  • The existence of the maintenance logbook and the reserve fund study;
  • The amount in the reserve fund and the monthly contribution;
  • The current state of the condominium (planned work, special assessments, etc.).

This certificate becomes a key document in any real estate transaction, allowing buyers to make an informed decision.


Stricter Management for Everyone’s Safety

Bill 16 aims to professionalize condominium management. It helps prevent building deterioration, protects occupant safety, and preserves the value of units on the real estate market. While it requires greater rigor and transparency, it represents an essential investment in the long-term sustainability of the collective property.
