Density

In zoning, density refers to the intensity of development allowed on a parcel of land. Residential density is typically measured in dwelling units per acre (DU/acre), while commercial density may be measured by floor area ratio (FAR) or maximum square footage.

Floor Area Ratio (FAR)

For commercial and mixed-use development, density is often controlled by FAR — the ratio of total building floor area to lot area. A FAR of 2.0 means you can build 20,000 sq ft of building on a 10,000 sq ft lot (by building upward).

Why Density Matters for Real Estate

Density is one of the most direct drivers of land value. The same acre of land is worth dramatically more if it can support 20 apartments than if it can only support one single-family home. Zoning changes that increase permitted density — whether through rezoning, PUD approvals, or comprehensive plan amendments — are among the most value-creating decisions a municipality can make.

Density in Practice

When a municipality increases density allowances, it's responding to market demand for more housing or commercial space. Tracking density-related discussions in council meetings — including height increases, lot size reductions, and FAR adjustments — provides insight into where the market is heading and where development intensity is expanding.
