House Size Formula:
| From: | To: |
The Lot Size Vs House calculation determines the maximum allowable house size based on local zoning regulations. It multiplies the total lot area by the zoning ratio (also known as Floor Area Ratio or FAR) to determine the maximum building footprint.
The calculator uses the simple formula:
Where:
Explanation: Zoning regulations limit how much of a lot can be covered by buildings. The zoning ratio determines what percentage of the lot can be built upon.
Details: Zoning ratios help maintain neighborhood character, prevent overcrowding, ensure adequate light and air circulation, and manage infrastructure demands. Different zones (residential, commercial) have different ratios.
Tips: Enter the total lot size in square feet and the applicable zoning ratio. Check with your local planning department for accurate zoning information specific to your property.
Q1: What is a typical zoning ratio for residential areas?
A: Residential zoning ratios typically range from 0.2 to 0.6, meaning 20-60% of the lot can be covered by buildings.
Q2: Does this calculation include multiple stories?
A: No, this calculates the maximum footprint. Total building area would be footprint multiplied by number of stories, subject to height restrictions.
Q3: Are there other zoning restrictions to consider?
A: Yes, setbacks, height limits, lot coverage percentages, and other regulations also affect what can be built on a property.
Q4: How do I find my property's zoning ratio?
A: Contact your local planning or zoning department, or check your municipality's online zoning maps and ordinances.
Q5: Can variances be obtained to exceed the zoning ratio?
A: In some cases, property owners can apply for variances, but these are typically granted only under specific circumstances and require approval processes.
