# Floor Area Ratio Calculator MCP for AI Agents AI Agent Connect

> Floor Area Ratio Calculator helps you determine exactly how much you can build on a piece of land. It calculates maximum ground footprints, total floor area, and green space compliance based on your local zoning rules. Use it to skip the manual math and get instant feasibility numbers for any plot size.

## Description

Developing property is a game of balancing conflicting rules. You have to figure out how much ground you can cover, how much total bulk is allowed across all floors, and how much space must remain open for water absorption. It is a manual headache that often leads to expensive mistakes when one metric is overlooked. This Connector handles the heavy lifting by connecting your agent to the core math of urban planning. You can quickly check if a project meets site coverage limits, calculate the total floor area allowed by your local Floor Area Ratio, and verify that you are leaving enough room for green space mandates. It is a key part of how Vinkius helps professionals move from guesswork to hard numbers. Instead of triple-checking spreadsheets, your agent handles the math and tells you exactly where you hit a wall. You get a clear picture of what is actually buildable before you ever put pen to paper.

## Tools

### calculate_permeability
This tool calculates the minimum permeable area required for a lot. It helps you figure out how much buildable ground is left after meeting green space mandates.

### max_site_coverage
This tool determines the maximum allowable ground footprint for a plot. It uses your site coverage percentage to set a hard limit on building construction.

### max_total_area
This tool calculates the total permitted floor area across all stories. It uses the Floor Area Ratio to ensure your project meets density compliance.

## Prompt Examples

**Prompt:** 
```
We have a plot of 10,000 sq units. The zoning requires a max site coverage of 60% and a minimum permeability of 30%. What is the maximum total floor area we can build?
```

**Response:** 
```
Here is the feasibility breakdown for your 10,000 sq unit plot:

| Metric | Value |
| :--- | :--- |
| **Max Footprint** | 6,000 sq units |
| **Required Permeable Space** | 3,000 sq units |
| **Usable Buildable Footprint** | 5,000 sq units |

Based on a Floor Area Ratio (FAR) of 2.5, your **maximum total floor area is 12,500 sq units**. 

*Note: This assumes the FAR applies to the usable footprint after permeability requirements are met.*
```

**Prompt:** 
```
Given a 100 sq unit plot with an FAR of 2.5, what is our maximum total buildable area?
```

**Response:** 
```
For a 100 sq unit plot with a Floor Area Ratio of 2.5, the **maximum total buildable area is 250 sq units**.

Keep in mind that your actual footprint will be further limited by your local site coverage and permeability percentages.
```

**Prompt:** 
```
Verify that our proposed 40% ground footprint on a 5,000 sq unit lot meets zoning standards for occupancy.
```

**Response:** 
```
I have checked the site coverage for you:

*   **Plot Area:** 5,000 sq units
*   **Proposed Footprint:** 2,000 sq units (40%)

**Status:** ✅ **Pass**. Your proposed 40% footprint is within the legal limit for a 40% site coverage zoning requirement.
```

## Capabilities

### Calculate max footprint
Determines the largest ground area your building can occupy based on site coverage limits.

### Determine total floor area
Calculates the total permitted square footage across all stories using Floor Area Ratio.

### Verify permeability requirements
Checks if your design leaves enough non-impervious space to meet green space mandates.

### Check zoning compliance
Identifies which specific zoning constraint is the most restrictive for a given plot.

### Identify buildable area
Subtracts required permeable space from the maximum allowable footprint to find usable ground.

## Use Cases

### Quick feasibility check for a new apartment block
A developer asks the agent if they can build a 5-story building on a 10,000 sq unit lot. The agent uses max_total_area and max_site_coverage to confirm if the density is legal.

### Verifying green space for a retail center
A land use consultant needs to know if a proposed parking lot leaves enough room for water absorption. They use calculate_permeability to check the lot.

### Comparing different building heights
An architect wants to see if a taller, thinner building is better than a shorter, wider one. The agent runs both scenarios using max_total_area and max_site_coverage.

### Initial site assessment for a land purchase
A real estate investor wants a quick summary of what can be built on a new listing. The agent provides a buildable area summary in seconds.

## Benefits

- Stop guessing on site limits by using max_site_coverage to get an instant maximum footprint for any plot size.
- Avoid costly planning errors by using max_total_area to see the exact floor area limit allowed by your local Floor Area Ratio.
- Ensure your project meets environmental rules by using calculate_permeability to verify green space compliance.
- Identify the most restrictive zoning constraint immediately instead of finding it out during the permitting phase.
- Run multiple 'what-if' scenarios in seconds to see how different building heights impact your site coverage.
- Move from manual spreadsheet math to automated feasibility checks that your agent can run on command.

## How It Works

The bottom line is you get a clear answer on what is actually buildable on a piece of land.

1. Provide the plot area and the specific zoning percentages for coverage, FAR, and permeability.
2. The agent runs the calculations to check each constraint against the others.
3. You get a clear breakdown of the maximum buildable footprint and total floor area.

## Frequently Asked Questions

**Can the Floor Area Ratio Calculator check my specific local zoning laws?**
No, this tool does not have a database of every city's rules. You need to provide the specific percentages for coverage, FAR, and permeability from your local municipality's zoning code.

**How does the Floor Area Ratio Calculator handle green space?**
It uses the calculate_permeability tool to determine how much non-impervious space is required. It then helps you figure out how much buildable ground remains after those requirements are met.

**Can I use the Floor Area Ratio Calculator for multi-story buildings?**
Yes, that is exactly what it is for. It uses the Floor Area Ratio to calculate the total permitted area across all stories of a multi-story project.

**Does the Floor Area Ratio Calculator include road requirements?**
No, it focuses on the three core metrics of site coverage, total floor area, and permeability. You would need to subtract road requirements from your plot size before running the calculations.

**How accurate are the results from the Floor Area Ratio Calculator?**
The results are as accurate as the data you provide. It uses the exact formulas required for urban planning to give you precise numbers for your feasibility studies.

**If I increase the building size, which constraint is most likely to fail first: Site Coverage or Permeability?**
The relationship between these constraints is complex. You must run `max_site_coverage` first to find the maximum ground footprint. Then, use this result in `calculate_permeability`. The permeability check will often be the most restrictive physical constraint because it mandates a minimum unpaved area before considering building size.

**Can I calculate the total buildable space without knowing the ground footprint?**
Yes, you can use `max_total_area` with just the plot area and the FAR ratio. However, for a complete assessment, you should always run `calculate_permeability` as well, because permeability might force your buildable footprint to be smaller than what `max_total_area` assumes.

**What is the role of plotArea in these calculations?**
The `plotArea` (or `lotArea`) is your fixed starting point--the total surface area of the land parcel. It serves as the base input for all three tools (`max_site_coverage`, `max_total_area`, and `calculate_permeability`), providing the dimensional context against which zoning rules are applied.
