What building in Vaughan involves

Much of the custom work in Vaughan is replacement housing. An older house on a mature lot comes down and a larger one goes up. That makes the zoning review the first job, because the by-law sets the lot coverage, height, setbacks and driveway width that the new house has to meet.

Lots that back onto the Humber or the Don bring the conservation authority into the process. The limit of the valley and the setback from it are fixed before the house is designed, because they reduce the part of the lot that can be built on.

In the four heritage conservation districts, new houses, additions and exterior changes are reviewed against the district plan before a building permit is issued.

What the zoning by-law controls

The standards differ by zone and by municipality. The questions are the same on every lot.

Vaughan questions

Which zoning by-law applies to my lot in Vaughan?

Comprehensive Zoning By-law 001-2021 is the current by-law. The zoning review confirms the zone, any site-specific exception and whether any transition rule from the earlier by-law is relevant.

Is my lot regulated by the TRCA?

It may be if it is in or beside a valley, a stream corridor or a wetland. The conservation authority’s mapping shows the regulated area, and we check it at the start.

When can construction start in Vaughan?

At 7 a.m., Monday to Saturday, and it has to stop at 7 p.m. Construction is not permitted on Sundays or statutory holidays without a noise exemption from the City.

Do you work in Kleinburg?

Yes. Kleinburg has its own heritage conservation district and is covered on a separate page.
