What is a zero lot line? – David Reecher
A zero-lot-line property is a building that comes to the very edge of the property line on at least one side. In a zero-lot-line housing development, units may be attached to one another, leaving no room for a yard. Many townhouse developments are built on zero-lot lines. In some cases, there may be a yard between the units, but the exterior wall of one home sits on the lot line of the neighbor’s property or yard.
