• Parking points  (normally one per unit)
• Setback distance from property line
• Height restrictions for buildings

You can inquire this with the Town of Caledon Planning Department or with a zoning consultant or an architect who understands local zoning.

Pre-Consultation With the Town of Caledon

After  zoning eligibility is confirmed and verified, you should book your appointment with the Caledon Building Services department for a pre-consultation meeting. This meeting assists to outline:

Skipping  Zoning Verification

A big mistake is to assume that your property qualifies for triplex without checking zoning laws. Each zone in Caledon has rules for density, lot size, and parking. Applications can be rejected because of failure to confirm zoning. It will also lead to wasting of planning expenditure. Contact the Caledon zoning map or planning consultant and be sure before going ahead.

Poor Permit Documentation 

Submission of incomplete or inaccurate permit applications is a major cause of processing delays. Missing architectural drawing, structural information, or HVAC plans can stop progression of your project. The municipal staff will decline to accept or return your file until it becomes complete and compliant. Remember you can engage an experienced architect or planner to make sure  everything is in the right order.

Hiring Unlicensed Contractors

Hiring the lowest bidder or Unlicensed contractors often means cutting corners and code violation risks. Workers without a license may not follow the standards of the Ontario Building Code. Their works may fail inspection, which  requires costly rework or or fines. The licensed professionals always be insured with a track record in legal conversions 

Ignoring Fire Separation Requirements

The legal triplex conversion in Ontario cannot be carried out without fulfilling fire safety requirements. There should be adequate fire-rated doors, walls, and ceilings between separate units. Many applicants omit this mandate requirement, only to be denied occupancy in the future. Ask the fire inspector or building official as soon as the design is drafted.

Starting Work Without a Permit

Your unapproved work can be either demolished or redone at your cost. Before the breaking ground moves, wait for the official triplex permit Caledon.
