Entitlements Calculator
Calculate allowed buildable area and number of units based on zoning code, lot size, FAR, and density requirements.
How it works
Calculates maximum buildable square footage using FAR, then determines maximum units based on density limits, parking constraints, and unit sizes.
Example
10,000 sq ft lot × 1.0 FAR = 10,000 sq ft buildable. At 1,000 sq ft/unit = 10 units max.
FAQ
What is Floor Area Ratio (FAR)?
FAR is the ratio of total building floor area to lot size. A 0.5 FAR means you can build half the square footage of your lot size across all floors.
How does density affect the number of units allowed?
Density limits specify maximum units per acre or per square foot. For example, 20 units per acre on a 0.5-acre lot allows up to 10 units.
What are setback requirements?
Setbacks require minimum distances from property lines. They reduce the buildable area but don't typically affect FAR calculations directly.
How do parking requirements affect development?
Parking requirements specify minimum spaces per unit or per square foot. Limited parking can constrain the number of units you can build.
Can I exceed FAR with bonuses or incentives?
Many jurisdictions offer density bonuses for affordable housing, green building, or other public benefits that can increase allowable FAR.
