Building in Ancaster
What shapes a custom home in Ancaster
We build in Meadowlands, the Old Ancaster village core, Fiddler's Green and the escarpment-edge streets. Larger, older lots and treed escarpment parcels are common here. Conservation authority and Niagara Escarpment Commission approvals can apply.
How many units the lot allows
Ancaster is part of the City of Hamilton. Hamilton says a lot can have up to four dwelling units in some zones, made up of the main house plus internal and detached additional dwelling units. Some Ancaster lots are still under the former Ancaster Zoning By-law 87-57.

For new single detached homes in the ER zone of the former Ancaster Zoning By-law 87-57, Hamilton says a Zoning Compliance Review may be required with the building permit application.

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.
