Bill 16 in plain language

What the regulation requires of your syndicate, and when

Bill 16 (2019) reformed divided co-ownership in Québec; its implementing regulation (Order in Council 991-2025) has been in force since August 14, 2025. It requires three tools of every syndicate: the maintenance log, the reserve fund study and the syndicate certificate issued upon a sale.

Who is affectedEvery syndicate of divided co-ownership in Québec, regardless of the number of units or the size of the building. The only condition: being constituted as a divided co-ownership.

DeadlineA period of 3 years and 1 day after the regulation came into force: the first maintenance log and the first study must be obtained no later than mid-August 2028. The syndicate certificate is already required upon any sale.

The reserve fund studyRenewed every 5 years, without exception. It projects major repairs and replacements over at least 25 years, year by year, and recommends the annual contributions and the minimum amount to keep in the fund.

The maintenance logUpdated every year by the board or the manager, and reviewed by a professional every 5 years — or every 10 years for small co-ownerships (8 private portions or fewer, 3 above-ground storeys or fewer, or common portions located outside a building).

Who may produce themAn engineer, an architect, a professional technologist or a chartered appraiser (and a CPA for the study), independent of the syndicate. At Darheim, both documents are produced in-house by our professional technologists (OTPQ) and engineers (OIQ).

Already done?A log or a study prepared between August 14, 2023 and August 14, 2025 by an authorized professional is recognized; it will have to be reviewed 5 years after its date.

Good to know: the study must be based on a compliant maintenance log. Entrusting both to the same team avoids duplicate inspections — and inconsistencies between two professionals.

Self-assessment · 30 seconds

Is your co-ownership up to date?

Five checkboxes to find out whether your maintenance log must be reviewed every 5 or every 10 years, and what you still need to obtain before the August 2028 deadline.

This tool gives a general indication based on the regulation in force. Our team confirms your exact situation and deadlines as part of your service proposal.

1. How often your log must be reviewed

Log reviewed every 5 yearsNo exception checked: the log must be reviewed by a professional at least every 5 years. The reserve fund study is always renewed every 5 years.

2. Where do you stand?

To obtain before mid-August 2028You are missing both the maintenance log and the reserve fund study. Our team produces both during a single inspection.

Frequently asked questions

Everything we get asked about Bill 16

Yes. Since the regulation came into force on August 14, 2025, every syndicate of divided co-ownership in Québec must obtain a compliant maintenance log and reserve fund study, whatever the size of the building. The deadline is 3 years and 1 day, i.e. until mid-August 2028.

The general rule is a review by a professional at least every 5 years. It becomes 10 years if your co-ownership meets at least one of these conditions: 8 private portions or fewer (not counting parking and storage spaces), 3 fully above-ground storeys or fewer, or common portions that are not located in a building. In all cases, the log must be updated every year by the board, and the reserve fund study renewed every 5 years.

If it was prepared between August 14, 2023 and August 14, 2025 by an authorized professional (engineer, architect, technologist, chartered appraiser or CPA) and its content meets the regulation, it is recognized and will have to be renewed 5 years after its date. A study dated before August 2023 must be redone or updated to the new requirements before August 2028. We can check the compliance of your existing document.

Our in-house team: professional technologists who are members of the OTPQ and engineers who are members of the OIQ, all authorized under the regulation and independent of your syndicate. No step is subcontracted, from the inspection to the signing of the documents.

A tool reserved for our clients, at no cost, in which your board or your manager can record, year after year, the co-ownership’s interventions, contracts, warranties and reports. It makes the annual update required by the regulation easier; the review by a professional is still required at the applicable frequency (5 or 10 years).

Yes, under the terms set out in the service proposal. After the file is delivered, we remain available to answer your board’s or your manager’s questions about the content of the log and the study.

The reserve fund is used for major repairs and the replacement of the common portions, planned over 25 years. The self-insurance fund covers the syndicate’s insurance deductibles in the event of a loss. Both are mandatory, but only the reserve fund study is covered by our mandate.

An analysis based on the maintenance log, a year-by-year estimate of major repairs and replacements over at least 25 years, adjusted for inflation, the recommended annual contributions to the fund and the minimum amount to keep in it, as well as separate recommendations for common portions for restricted use, where applicable.

The inventory and description of the common portions (materials, equipment, installation dates), the assessment of their condition and remaining useful life, the 25-year major works plan, the routine maintenance schedule and an archiving section for reports, contracts and warranties.

Fill out the form below describing your co-ownership. Every request is reviewed by our team; if your project fits our practice, you will receive a detailed service proposal by email within a maximum of two weeks. The price depends on the number of units, the age and complexity of the building and the existing documentation.

Yes, provided your log complies with the regulation and is up to date. We check it first; if elements are missing, we complete it rather than starting from scratch.

Upon every sale, the syndicate must provide within 15 days a certificate stating, among other things, the state of the fund and the studies carried out; the absence of a log and a study shows up immediately and can jeopardize a transaction. Directors also engage their liability if they fail to meet their obligations.

Yes. For buildings of 5 storeys or more and for parking structures with concrete slabs, our structural engineers prepare the Bill 122 verification report — often during the same visit as the maintenance log inspection.
