Setback Calculator

Setback Calculator MCP Connector for Claude

A+

Determine maximum buildable area and optimal land utilization by applying local zoning setback rules.

3 tools Official Updated Jun 28, 2026 Official Vinkius Partner

Need to know how much you can actually build on your lot? Zoning laws dictate strict minimum setbacks (distances from property lines) that cannot be ignored. Ignoring these rules means building illegally and facing costly revisions.

3 tools expose this connector's capabilities to your AI agent.

calculate_building_footprint

Calculate the total buildable area and perimeter from usable envelope dimensions

calculate_land_utilization_metrics

Percentage is capped at 100% if footprint exceeds total area. Calculate how efficiently the plot is used by comparing built footprint area against total land area

calculate_usable_dimensions

Returns the maximum allowable building envelope dimensions in meters. Calculate the actual buildable dimensions after applying mandatory setback requirements to lot measurements

I have a lot that is 40m long and 25m wide. My local code requires a 5m front setback, 3m rear setback, and 4m side setbacks on both sides. What are my buildable dimensions?

To find this, I will execute the `calculate_usable_dimensions` tool with lotLengthMeters=40, lotWidthMeters=25, frontSetbackMeters=5, rearSetbackMeters=3, sideA_setbackMeters=4, and sideB_setbackMeters=4. The result will give me the maximum usable length and width.

Using my restricted dimensions of 32m by 17m, what is the total buildable area and perimeter?

I will run `calculate_building_footprint` with usableLengthMeters=32 and usableWidthMeters=17. This provides the total footprint area in square meters, which is essential for zoning submissions.

If my lot's total area is 800 sq.m., and the building footprint is 512 sq.m., what percentage of land can I actually use?

I will call `calculate_land_utilization_metrics` using totalLandAreaSqMeters=800 and buildingFootprintAreaSqMeters=512. This calculation gives the utilization percentage, confirming compliance.

You must first use the `calculate_usable_dimensions` tool. This function takes your total lot size and mandatory setbacks (front, rear, side A, side B) to determine the absolute maximum buildable length and width.
