What does "Infill" mean?

“Infill” refers to land surrounded by other development built areas, where raw vacant land is scarce.  Infill usually refers to dense urban locations.

The term “infill” is used to describe land surrounded by previously built structures and is the opposite of rural land where land development is widely available.  In Los Angeles, there is a lot of infill locations, just not that many that are available to buy and build on.  Developers want infill locations for different reasons, multifamily developers want infill because it makes it easier to rent units, retail developers want infill because typically traffic counts are higher, office building developers want infill because there are more companies in denser areas.   That said, each infill site is different due to zoning.
