Divided or Undivided Condo in Montreal: What You Really Need to Know Before Buying

By Michele-V. Guzzo, Real Estate Broker — MVG Immobilier | Royal LePage Urbain

Buying a condo in Montreal means juggling prices, interest rates, and multiple offers. But there’s one question many buyers ask too late: is this a divided or undivided condo?

The answer changes everything. Not just legally — it determines your down payment, your financing options, your resale rights, and what the law guarantees you at the time of purchase. Here’s what you need to understand before making an offer.

What’s the Difference?

Divided Condo

You own your unit and a share of the common areas — stairways, roof, foundations. Your condo has its own lot number in the land registry, its own municipal and school tax bill. You can sell or refinance without the consent of other co-owners.

Undivided Condo

You hold a percentage of the entire building, without an individual lot number. You sign an indivision agreement with the other co-owners to define usage rights, financial obligations, and shared living rules. No separate land title, no individual tax bills: everything is shared proportionally.

The Real Impact: Financing

This is where many buyers get caught off guard, often at the worst possible moment.

For a divided condo under $500,000, the minimum down payment is 5%. Between $500,000 and $1,499,999, the structure is graduated: 5% on the first portion, 10% on the rest. For an undivided condo, regardless of price, it’s 20% with no exceptions — and CMHC mortgage insurance does not apply.

This isn’t a problem if you’re well prepared. It’s a nightmare if you find out halfway through a purchase agreement.

The Indivision Agreement: What You’re Really Signing

In an undivided condo, the indivision agreement governs your daily life as a co-owner. It defines:

• Who occupies which unit (exclusive usage rights)
• How shared expenses are divided — maintenance, insurance, major repairs
• The right of first refusal: before selling to a third party, you must first offer your share to the other co-owners
• Procedures in case of disagreement or the departure of a co-owner

A well-drafted agreement protects everyone. A sloppy or missing one is a source of conflict. Have it reviewed by a notary before signing anything.

What Bill 16 Changes for Divided Condos

Since August 14, 2025, Bill 16 (Loi 16) has been fully in force for all divided co-ownerships in Quebec. Three concrete obligations apply to every condo syndicate:

The Syndicate Certificate

Mandatory for every sale since August 14, 2025. The seller must provide you with an official document indicating the state of the contingency fund, planned work, ongoing disputes, and the building’s compliance. You buy with a clear picture of the co-ownership’s financial health.

The Maintenance Log

It documents the condition of every building component and plans work over a 25-year horizon. It must be produced by an independent, authorized professional. Compliance deadline: August 14, 2028.

The Contingency Fund Study

It quantifies how much needs to be set aside each year to avoid surprise special assessments. It must be renewed every five years.

Bill 16 does not apply to undivided co-ownerships. That doesn’t mean undivided condos are less well managed — but it does mean you have fewer legally mandated protections at the time of purchase. All the more reason to review the indivision agreement carefully.

Value and Resale

An undivided condo typically sells for less than a comparable divided unit. The gap is directly tied to financing constraints: the pool of potential buyers is smaller since 20% down is required.

• Resale takes longer, especially in softer markets
• In highly sought-after areas like Rosemont, the Plateau, or Mile-End, demand stays strong and values hold well
• The price gap can represent an opportunity to enter a neighbourhood where divided condos are out of reach

A Concrete Example in Rosemont

Imagine two similar units: 2 bedrooms, 850 sq ft, same finishes, same street.

• Divided: asking price $450,000. Minimum down payment: $22,500 (5%).
• Undivided: asking price $390,000. Required down payment: $78,000 (20%).

The undivided condo costs less to buy — but requires significantly more liquidity. For some buyers, that’s a barrier. For others, it’s the door into a sought-after neighbourhood.

Note: these figures are illustrative. Actual prices vary by unit, building, and market conditions.

When an Undivided Condo Makes Sense

An undivided condo can be an excellent strategic choice if you:

• Want to buy in a desirable neighbourhood at a lower price
• Already have your 20% down payment available
• Plan to stay for several years — a 5-year-plus horizon
• Are comfortable with a more collaborative co-ownership structure

Key Takeaways

There’s no right or wrong choice between divided and undivided — it all depends on your profile, your timeline, and your financial capacity. But there is a very real risk: discovering the property type after you’ve already signed a purchase agreement.

Ask the question from the start. Review the indivision agreement. Request the syndicate certificate for a divided condo. Talk to your financial institution before getting excited. And if possible, work with a broker who knows both sides of the Montreal market.
