Building in Cambridge
What shapes a custom home in Cambridge
We build in Galt, Hespeler, Preston, Blair and the river-valley streets. Historic Galt, Hespeler and Preston lots often involve heritage and Grand River floodplain checks.
How many units the lot allows
Cambridge allows up to two additional residential units on a lot with a detached, semi or townhouse (three units in total), under Section 4.19 of its new Zoning By-law 26-007.

The city says neither Cambridge nor the Region of Waterloo collects development charges for ARUs. The school boards may in some cases.

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.
