Selling Your Plex Unit by Unit as Condos: Why It's Almost Impossible on the North Shore

Many plex owners dream of it: selling their building unit by unit as condos, pocketing the premium per square foot that the residential market commands. In theory, the math is attractive — a triplex worth $900,000 as a rental building might sell for $1.2M+ as three separate condos. In practice, on the North Shore in 2026, three regulatory barriers make this strategy nearly impossible for an occupied building.

This is not a recent development. Quebec has been tightening the rules around conversion to divided co-ownership (copropriété divise) since the 1990s, and recent amendments have reinforced them further. Here are the three barriers — and why most owners are better off selling the whole building instead.

Barrier 1: TAL Authorization — Almost Never Granted

Under the Quebec Civil Code and the Act Respecting the Rental of Dwellings, any conversion of a rental building to divided co-ownership requires authorization from the Rental Housing Tribunal (TAL) if the units are occupied or have been occupied within the preceding 12 months. This is not a formality: the TAL carries out a genuine assessment.

The Tribunal weighs two main factors: whether the housing is needed for rental purposes in the local market, and whether the conversion would cause undue prejudice to existing tenants. In a context of low vacancy rates — which has been the reality on the North Shore for several years — the TAL systematically concludes that rental housing is needed. Authorization is therefore denied in the vast majority of cases.

Even if you believe your case is exceptional — tenants who have agreed to leave, a building in poor condition, a municipality with more flexible rules — you must submit a formal application to the TAL, attend a hearing, present evidence, and wait for a decision. The process takes months and is far from guaranteed.

This barrier alone, combined with the current state of the rental market, is enough to make conversion a losing bet for most owners. The situation is part of a broader context we analyze in our column on the housing policies weighing on the small plex landlord.

Barrier 2: The Municipal Moratorium — A Legal Wall

Even if the TAL were to authorize a conversion, a second barrier can block it entirely: the municipal moratorium on conversion. Quebec municipalities have the power — under the Act Respecting Land Use Planning and Development — to adopt a by-law prohibiting the conversion of rental housing to divided co-ownership in all or part of their territory.

Several municipalities on the North Shore and in Greater Montreal have exercised this power. For an owner whose building falls within a moratorium zone, conversion is simply legally impossible until the by-law is lifted — regardless of what the TAL might decide. Check with your municipality's urban planning department to determine whether a moratorium applies to your property.

The moratorium was designed precisely to prevent the loss of affordable rental stock through conversion. Combined with the TAL requirement, it creates a double lock that very few owners can open. This also relates to the municipal right of first refusal and the welcome tax — a set of constraints that collectively make the life of a plex investor more complex year after year.

Barrier 3: Tenants' Unlimited Right to Stay

The third barrier is perhaps the most misunderstood. Quebec law — specifically Article 1664 of the Civil Code — grants every tenant an unlimited right to maintain their tenancy, even if their unit is converted to divided co-ownership and sold as a condo. The new owner of a condo unit in a converted plex acquires the unit with the tenant in place, and cannot evict them simply because they now own the title.

In practice: even if you obtained TAL authorization, even if your municipality has no moratorium, you cannot force a single tenant to leave to sell the unit as a condo. The tenant must voluntarily agree to end their tenancy. Without that agreement, the unit can only be sold occupied — which dramatically reduces the premium a buyer is willing to pay.

Some owners attempt to negotiate with tenants, offering compensation in exchange for voluntary departure. This can work in isolated cases, but it requires the goodwill of each tenant, sometimes over years. An owner who counts on being able to convert their triplex in a reasonable timeframe is almost always disappointed. The impossibility of conversion is also a factor that weighs on those considering renoviction as an alternative — another path that has become extremely restricted since Loi 31.

🎭 Devil's Advocate: Is There a Scenario Where It Works?

Honestly: yes, in very specific circumstances. An owner who acquires a fully vacant building — no current tenants, no tenancy in the preceding 12 months — and who is located in a municipality without a moratorium and who can demonstrate to the TAL that the local market can absorb the loss of rental units may obtain authorization and successfully complete a conversion.

It also works when tenants voluntarily negotiate their departure in exchange for meaningful compensation, or when a single unit becomes vacant naturally (natural turnover) and the building only has two or three units to start with. In these rare situations, conversion can indeed yield a significant premium over a whole-building sale.

But for the typical owner of an occupied triplex or quadruplex on the North Shore, with tenants in place for several years, the realistic assessment is: conversion is not a viable exit strategy in the short or medium term. The regulatory, legal and practical obstacles are simply too numerous. The economic value of a Quebec plex in 2026 is better unlocked through a whole-building sale.

The Verdict: Sell the Building, Not Unit by Unit

Our conclusion is simple: for the vast majority of North Shore plex owners with tenants in place, conversion to divided co-ownership is not a realistic option. The TAL barrier, the municipal moratorium and tenants' unlimited right to stay combine to create an obstacle course that takes years, costs tens of thousands in legal fees, and offers no guarantee of success.

The realistic alternatives are: continue residential rental as a whole building, sell to an investor who will continue the same use, or sell directly to a specialized buyer. The whole-building sale eliminates all conversion-related complexity: no TAL application, no moratorium to check, no tenant negotiations. You receive a net price for the building as-is.
