1. What is Dwelling Units per Acre?

Dwelling units per acre (DU/A) is a measurement of residential density that calculates the number of housing units on a given area of land. It's commonly used in urban planning and zoning regulations.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• Total Units — Number of residential dwelling units
• Acres — Total land area in acres

Explanation: The calculation divides the total number of dwelling units by the total land area to determine the density.

3. Importance of DU/A Calculation

Details: DU/A is crucial for urban planning, zoning compliance, infrastructure planning, and assessing the environmental impact of development projects.

4. Using the Calculator

Tips: Enter the total number of dwelling units and the land area in acres. Both values must be positive numbers (acres must be greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What's considered low, medium, and high density?
A: Typically: Low (1-4 DU/A), Medium (5-15 DU/A), High (16+ DU/A), though definitions vary by municipality.

Q2: Does this include common areas and roads?
A: Generally yes - the total site area should include all land within the development boundaries.

Q3: How does this differ from population density?
A: DU/A measures housing units, while population density measures people per area (which depends on household size).

Q4: Should I use gross or net acreage?
A: Most zoning codes specify whether to use gross (total) or net (buildable) acreage - check local regulations.

Q5: How is this used in zoning?
A: Many zoning districts have maximum DU/A limits to control neighborhood character and infrastructure demands.
