Zero-Lot Line
Definition and meaning of Zero-Lot Line in real estate.
Zero-Lot Line refers to a residential or commercial structure positioned so that at least one of its exterior walls sits directly on the boundary line of the property, leaving no yard space on that side.
In more detail
This design style is common in urban areas, townhome developments, and patio home communities where land is scarce and expensive. By eliminating the traditional side yards required by local zoning ordinances, developers can maximize the square footage of the home and fit more properties onto a single tract of land.
Maintenance agreements, often called party wall agreements or maintenance easements, are usually recorded to allow neighbors access to the adjacent property to paint or repair the wall sitting on the boundary. Buyers should review these property restrictions to understand their rights regarding repairs, landscaping, and renovations.
