Building a Custom Home in Markham: What to Check Before Design
Building a custom home in Markham should begin with a review of the property not a finished floor plan. Zoning, heritage status, grading, mature trees, servicing, and nearby natural features can all affect what can be built and how the approval process will work.
Checking these items early can prevent costly redesigns and provide a more realistic budget and project schedule.
Confirm What the Property Allows
Start by checking the property through the City of Markham’s zoning and permit resources.
The review should confirm:
- Required front, rear, and side yard setbacks
- Maximum building height and lot coverage
- Garage and driveway requirements
- Site-specific zoning exceptions
- Whether a minor variance may be needed
Do not assume that a neighbouring home proves the same design can be approved on your property. Nearby lots may have different dimensions, zoning provisions, easements, or previous approvals.
Check Heritage, Trees, and Conservation Requirements
Markham includes heritage conservation districts in Unionville, Markham Village, Thornhill, and Buttonville. Use the Markham Heritage Districts and Property Register to check whether heritage review may affect demolition, exterior design, materials, roof forms, windows, or driveway changes.
Existing trees should also be reviewed before the home and driveway are positioned. Construction near protected trees may require a tree permit or preservation plan.
Properties near the Rouge River, Berczy Creek, wetlands, valleys, or flood-prone areas may also require conservation review. The applicable requirements should be confirmed before the building footprint or grading plan is finalized.
Coordinate Grading and Servicing Early
For many new infill homes, Markham’s Residential Infill Grading and Servicing process is an important part of the approval path.
Grading and servicing can affect:
- Foundation and entrance elevations
- Garage height and driveway slope
- Drainage between neighbouring properties
- Retaining walls and drainage swales
- Water, sanitary, and storm connections
- Construction access
The architectural, structural, and grading plans should be developed together. Leaving grading until the permit stage can force changes to the garage, basement, entrance, or overall building height.
What Should a Lot Review Tell You?
Before purchasing a property or completing the design, a useful lot review should answer five questions:
- What can be built under the current zoning?
- Are heritage, tree, or conservation approvals involved?
- Is a minor variance likely to be required?
- Are there grading, servicing, or access constraints?
- How could these conditions affect the budget and timeline?
