1. What is Land Lot Coverage?

Land lot coverage is the ratio of building footprint area to the total lot area. It's a key metric in urban planning and zoning regulations that determines how much of a property can be built upon.

2. How Coverage is Calculated

The coverage is calculated using this simple formula:

Where:

• Building Footprint — Area covered by the building (m²)
• Lot Size — Total area of the land parcel (m²)

Explanation: The result can be expressed as a decimal (e.g., 0.45) or percentage (e.g., 45%). Most zoning regulations specify maximum allowable coverage percentages.

3. Importance of Coverage Calculation

Details: Calculating land lot coverage is essential for compliance with zoning laws, determining buildable area, planning site layouts, and assessing environmental impact.

4. Using the Calculator

Tips: Enter building footprint and lot size in square meters. Both values must be positive numbers. The calculator will provide results in both decimal and percentage formats.

5. Frequently Asked Questions (FAQ)

Q1: What's included in building footprint?
A: The footprint includes all areas covered by buildings at ground level, including overhangs and cantilevered sections.

Q2: What are typical coverage limits?
A: Residential zones often allow 30-50% coverage, while commercial zones may allow up to 80-100%. Check local zoning codes.

Q3: Does coverage include multiple buildings?
A: Yes, the footprint of all buildings on the lot is summed for coverage calculations.

Q4: How does coverage differ from FAR?
A: Coverage measures ground area occupied, while Floor Area Ratio (FAR) considers total building floor area across all stories.

Q5: Are driveways and patios included?
A: Typically no, but some jurisdictions include impervious surfaces in "lot coverage" calculations.
