Site Valuation and Cost Approach

Market Conditions: Bracket Land Sales

Bracketing groups historic sales by year and tracks how prices have changed over time. The result is a defensible market conditions rate of change. This problem requires judgment — there is no single correct answer. Different appraisers may justify different rates depending on which group-pair they emphasize.

Floor Area
Ratio (FAR)

The floor area ratio (FAR) is the ratio of the gross building area (all floors combined) to the area of the site on which the building sits. It is one of the primary measures of building density used in zoning and land use analysis.

The formula is: FAR = Total Building Floor Area ÷ Site Area. A FAR of 1.0 means the gross building area equals the site area; a FAR of 2.0 means the building floor area is twice the site area. Higher FAR values typically indicate denser, more intensive land use.

When the FAR and the building’s coverage ratio (footprint ÷ site) are both known, the number of stories can be estimated as FAR ÷ Coverage Ratio. This is useful for understanding how a given allowable density translates into building height/stories given a particular footprint.
