A semi-detached home shares one wall with a neighbour and still gives you your own entrance, yard and full ownership of the building — usually at a meaningful discount to a comparable detached home. Amir Rehmani, MBA, Realtor®, helps buyers weigh that value trade-off street by street.
A semi-detached home is a full, freehold property that happens to share one wall with the house next door. You still own the lot, the roof and every wall except the party wall — but the shared structure typically brings the price down relative to a fully detached home on a similar street.
Semi-detached homes are especially common in Toronto's established east-end and west-end neighbourhoods, and in older sections of Mississauga and Brampton, where they offer more house and yard than a townhouse at a lower price than detached.
What buyers need to know before they offer.
Party-wall agreements govern shared structural elements — worth a look before you plan a major renovation.
The price gap between semi and detached varies block to block. A street-level comparison shows where the value actually is.
Additions and structural changes may need to account for the shared wall — confirm before you fall in love with a plan.
Original character, lot depth and parking tend to matter more for semi-detached resale than square footage alone.
Career figures below are estimates — ask Amir for current, street-level comparables before you offer.
Semi-detached homes are almost always freehold — you own the building and the lot outright, with no condo board or monthly fees. A party-wall agreement simply governs the shared wall with your neighbour.
It varies by street and city, but semis typically run 10–20% below a comparable detached home nearby. Ask Amir for a direct comparison in your target neighbourhood.
