Yes. I tell most Punjabi families I sit down with in Hamilton and Stoney Creek to look hard at a house with a legal second unit, even if parents will live in it for free or it sits empty this year. A self-contained unit is a full small apartment with its own kitchen and door. In Hamilton, the median asking price for an up-and-down duplex over the last twelve months was $749,450 on our Hamilton duplex, triplex and fourplex report.
That is close to what a regular house sold for. The average freehold home in Hamilton sold for $733,622 in October 2026, down 2% from a year earlier, according to our Hamilton market report for October 2026. One number is an asking price and the other is a sale price, so treat it as a rough compare. Still, the gap is small. A second kitchen and a second door are not costing families a fortune here.
I'm Gary Tiwana. I've been a Realtor with Found Spaces since 2018. My family is from Patiala, and I live on the Stoney Creek side of Hamilton. This is the one piece of advice I give over and over, and some people push back on it. Here is why I hold to it.
The second unit is for your family first
Most families I meet are not buying a rental. They are buying a home for three generations.
Maybe your parents are already in Canada. Maybe they are coming next year, or they split the year between here and Punjab. Maybe a younger brother is landing soon and needs a place to start. In our community, the question is rarely "will someone live there?" It is more often "who will live there first?"
A basement with a bed in it is fine for a few months. After that, everyone gets tired. Your mother wants her own kitchen so she can cook the way she likes, at the hours she likes, without anyone stepping around her, and your kids want to be loud without waking their grandfather at nine at night. A real second unit fixes that.
It gives everyone a door they can close. That matters more than people admit.
I've also seen the other direction. Nicole, whose father I helped, wrote that I worked with him on "both the sale of his longtime family home and the purchase of a new home" as he downsized. Parents get older. The big house stops making sense for them. A second unit in a son's or daughter's home is one honest answer to that, and it keeps the family close without anyone giving up their privacy.
What these homes cost in Hamilton and Stoney Creek right now
The numbers are friendlier than most families coming from Brampton or Mississauga expect.
On our Hamilton multiplex report, the median asking prices over the last twelve months were:
- Duplex, up and down: $749,450 (108 listings)
- Duplex, side by side: $694,450 (22 listings)
- Triplex: $799,900 (66 listings)
- Fourplex: $999,999 (27 listings)
Those are asking prices from listings, not final sale prices. An up-and-down duplex is the most common kind, which is good news. More choice means you can be picky.
Stoney Creek is quieter. In October 2026 there were 30 home sales, down 25% from a year earlier. The average freehold price was $737,246, down 14%. Homes sat for 50 days on average. That's all from our Stoney Creek market report for October 2026.
What does 50 days mean for you? It means time. You can ask for papers, bring a contractor and think it over at home with your family. You are less likely to be pushed into a bidding war on a Sunday night.
I don't have Brampton or Mississauga numbers in our reports, so I won't guess at the gap. What I can tell you is what I hear from the buyers I work with who are moving west. They want more house, a bigger lot and fewer people bidding against them, and Hamilton and Stoney Creek are where they're finding it.
The year the plan changes
No family plan stays the same for five years. Someone loses a job. A parent decides to spend most of the year in India. A cousin who was supposed to move in buys his own place. The kids move out for school.
When that happens, a home with a legal second unit gives you a choice. A regular house doesn't.
Here is the number I watch. Over the twelve months to October 31, 2026, the median asking rent for a self-contained unit in Hamilton was $1,799 a month, based on lease listings we track. That's an asking rent, not a signed lease. But it shows what that empty space can turn into.
Picture a family of five moving from Brampton into an up-and-down house on the Mountain. For the first three years, the parents live downstairs and pay nothing, and the family pays the mortgage from two jobs. Then the father decides to spend winters in Punjab and summers with his daughter, so the downstairs sits empty most of the year. Around the same time, one of the two jobs ends. Because the unit is legal and ready, they rent it out for a year at a rent close to that median, and the rent covers a big part of the mortgage until work comes back. The house did not change. Their options did.
That's the real reason I push second units. It's a safety net you buy once and hope you rarely use.
Legal on paper, or just a basement with a stove
This is where families lose money. A listing that says "in-law suite" or "separate entrance" tells you very little.
A legal second unit has been approved by the city. It meets fire and building rules. That includes fire separation, which means walls and ceilings that slow a fire. It also includes a safe way out from the bedroom windows and proper smoke alarms. A basement with a stove and a side door might be none of those things.
When I walk a house with a basement unit, the first thing I do is ask the seller, in writing, for the city permit or registration for that unit. Then I go find the electrical panel. If there's only one panel and no sign of the work being inspected, I slow everyone down. Paper first, paint colours later.
Why does legal matter if your parents live there for free? Three reasons.
First, safety. It's your mother sleeping down there.
Second, insurance. If something goes wrong in a unit that was never approved, you want to know where you stand before you buy, and that means asking your insurance broker directly.
Third, the future. If you ever need to rent it out, or sell to someone who will, a legal unit is simply easier. Fixing an illegal one later can mean walls opened up, new windows cut and weeks of work.
Ontario now allows up to three units on most residential lots, and Hamilton allows second units and garden suites. A garden suite is a small separate house in the backyard. So if a house has no second unit today, a big lot with room at the side or back can still be a good buy. Before you count on adding one, check with the city what your exact lot allows. I'd never promise a family a unit the city hasn't said yes to.
What the bank sees when nobody pays rent
Here's the part families get wrong most often.
The bank only counts rent that is coming in. If your parents live downstairs for free, there's no rent. So the bank will look at your family's incomes alone to decide what you can afford.
I tell people to plan it that way from day one. Buy the house your family can pay for without a tenant. Then the second unit is a bonus and a backup, never the thing holding the whole plan up.
If you do rent it out, the rules can help a lot. Under CMHC rules for a home with two units where the owner lives in one, the minimum down payment is the same as a regular house: 5% on the first $500,000. Up to 100% of the gross rent, which is the full rent before costs, can count toward what the bank says you can afford. I walk through that version in detail in can I buy a Hamilton duplex with 5% down if I live in one unit.
Many Punjabi families buy together. A son and daughter-in-law plus a parent, or two brothers. Putting more than one income on the mortgage can raise what you can afford. It also means more than one name on the house and more than one person on the hook. Talk about that at the kitchen table before you talk to the bank, and get proper legal advice on how you hold title, meaning whose names are on the house and how.
What I'd do this month
If you're in Brampton, Mississauga or Toronto and thinking about Hamilton or Stoney Creek, I'd start with one thing. Write down who will live in the house for the next five years, year by year. Parents, kids, a relative coming from India, nobody.
That simple list tells me more than a budget does.
If the list has even one year where someone needs their own kitchen, look at homes with a legal second unit. If the list has a year where the space might sit empty, look at them even harder. And if you're open to renting part of the house out, our page on Hamilton investment properties and second-unit homes shows how we think about these houses as both a family home and a rental.
Then look at prices by building type. If you search for a duplex, compare the price per unit and not only the total. A side-by-side duplex at $347,225 per unit and an up-and-down at $374,725 per unit live very differently. Side by side means no one is walking over anyone's head. For older parents, that can be worth more than the difference.
I'll stand behind this. A family that buys a regular house and later needs a second unit has a hard, expensive job ahead. A family that buys a legal second unit and never rents it has spent a little more on a home that fits more lives.
My takeaway: buy the house your family can pay for without a tenant, and make sure it has a legal second door. You may never rent it. You'll still be glad it's there.
Questions people ask
Does the bank count rent from a basement unit if my parents live there for free?
No. The bank counts rent that is actually being paid, so a unit where family lives free adds nothing to what you can afford. The rules also change with size. For a three or four unit home, CMHC asks for at least 10% down, and only up to 50% of the gross rent, or the rent after costs, can count.
Is a basement unit or a garden suite better for older parents?
It depends on their knees and your lot. A basement unit usually means stairs every day, which gets harder as parents age. A garden suite is often on one level and gives more privacy, but you need enough yard and city approval, and you're building rather than buying it ready. If your parents are already in their seventies, I'd lean toward a main-floor or side-by-side setup.
What if the house I like has a second unit that is not legal?
You can still buy it, but go in with your eyes open. Ask the seller what was built, when and by whom, and get a contractor to price what it would take to make it legal before you agree on a price. That cost is a fair point to raise in your offer. Never assume a basement unit is legal just because people have lived in it for years.
