Lot Coverage Formula:
| From: | To: |
Lot Coverage Percentage is a zoning term that refers to the portion of a property that is covered by buildings or structures. It's calculated as the ratio of building footprint area to total lot area, expressed as a percentage.
The calculator uses the lot coverage formula:
Where:
Explanation: This calculation helps determine what percentage of a property is occupied by buildings, which is important for zoning compliance and urban planning.
Details: Calculating lot coverage is essential for ensuring compliance with local zoning regulations, proper land use planning, managing stormwater runoff, and maintaining green spaces in residential areas.
Tips: Enter the building area and lot area in square feet. Both values must be positive numbers, and the building area cannot exceed the lot area. The result will show the percentage of the lot covered by buildings.
Q1: What is typically included in "building area"?
A: Building area includes the footprint of all structures on the property - main house, garage, sheds, patios with roofs, and any other permanent structures.
Q2: What are typical lot coverage limits in residential zones?
A: Coverage limits vary by municipality but typically range from 25% to 40% for single-family residential areas. Always check local zoning ordinances.
Q3: Does lot coverage include driveways and sidewalks?
A: Typically no. Lot coverage usually refers only to areas covered by buildings and structures, not paved surfaces like driveways or walkways.
Q4: How does lot coverage affect property value?
A: Properties with appropriate lot coverage often have better resale value as they maintain a balance between living space and outdoor area.
Q5: Can I get a variance for lot coverage limits?
A: In some cases, yes. You would need to apply for a variance through your local zoning board, demonstrating that your request meets specific criteria.
