Building in Scarborough
What shapes a custom home in Scarborough
We build in the Bluffs, Guildwood, Wexford, Agincourt and the Highland Creek area. Wide postwar Scarborough lots leave room for a larger replacement house or a multiplex. Ravine and bluff lots need extra review.
How many units the lot allows
Toronto's By-law 474-2023 permits duplexes, triplexes and fourplexes in the R, RD, RS, RM and RT zones city-wide, so up to four units. Lots still under former Scarborough zoning may differ.

Toronto says properties zoned under a former municipal by-law aren't covered by its newer housing permissions in the same way. Call Toronto Building at 416-397-5330 if your Scarborough lot is one of them.

Ontario's Planning Act and O. Reg. 299/19 allow up to three residential units on a serviced urban residential lot, which matters if you want a suite in your new house or a garden suite out back.

Ontario's Building Code Act requires a permit to construct or demolish, so a knockdown-rebuild needs both. New homes must be built by a builder licensed by the Home Construction Regulatory Authority and enrolled for the Tarion new home warranty.
