Zero Lot Line
A type of residential construction where a house is built directly on or very close to the property boundary line, with little to no side yard setback. This design maximizes the use of small lots and is common in planned communities and urban developments where land is expensive.
Example
“The townhouse development featured zero lot line construction, allowing larger interior spaces by placing homes directly against the side property boundaries.”
Memory Tip
Think 'zero space to the line' - imagine a house sitting right on the edge of its lot with no side yard.
Why It Matters
Zero lot line homes allow developers to fit more houses on limited land while still providing homeowners with usable yard space, typically concentrated on one side or the back of the property. This design can make homeownership more affordable in areas with high land costs.
Common Misconception
Many assume zero lot line means the house actually sits on the property line itself, but most zoning codes require at least minimal setbacks, with "zero lot line" referring to the minimal side yard clearance rather than true zero distance.
In Practice
In a zero lot line subdivision, houses are built with 5-foot setbacks on one side and 15-foot setbacks on the other, allowing neighbors' homes to be positioned close together while each property maintains a usable side yard. Homeowners typically have easement agreements for maintenance access to the narrow side.
Etymology
Modern suburban planning term from the 1960s, literally describing homes built with 'zero' distance to the property 'lot line' boundary.
