3. Setbacks & Lot Sizes

Every residential zone has minimums:

Typical ranges (Harrison’s bylaw):

• Front setback: 4.5–6 m

• Rear setback: 6–7.5 m

• Side setbacks: 1.5–2.5 m

• Minimum lot sizes:

  • R-1: ~550–600 m²

  • R-2: larger

  • R-3/R-4: varies by density

These matter because relaxing them lets larger buildings or more units fit on smaller lots.
