Residential subdivision: what to understand before subdividing land

What is a residential subdivision?

A residential subdivision divides land into several plots for housing construction. The operation requires administrative approval and involves creating shared infrastructure (roads, utilities) serving all plots.

Preconditions for subdividing

• Own the land with a land title
• Minimum area generally required: 2,000 m² (varies by municipality)
• Land in a buildable zone under the land-use plan
• Access to an existing public road or creation of an access road
• Possible utility connections (water, power, sanitation)

The subdivision permit procedure

Technical standards to respect

• Minimum plot sizes: generally 300 to 500 m² in urban zones
• Minimum road widths: 6 to 8 metres for secondary roads
• Green spaces: minimum 10% of total area
• Reserves for public facilities depending on subdivision size
• Maximum road gradients per local standards

Indicative costs and profitability

A subdivision's profitability depends on the raw land acquisition price, servicing costs, administrative fees and plot sale prices. Generally, a well-planned subdivision in a demanded zone multiplies initial value by 3 to 6.

Mistakes to avoid

• Subdividing without administrative approval (demolition risk)
• Underestimating servicing costs
• Skipping preliminary technical studies
• Creating undersized, non-compliant plots
• Marketing before works acceptance
