How Close to Your Property Line Can You Legally Build?

The legal distance required between new construction and the property boundary lines is dependant upon the zoning ordinance where the property is located, the Voge Law Office explains. This distance is called a setback, and property owners should consult their local zoning office for setback regulations.

If the property owner needs to build closer to the property line then allowed by law, he may have the ability to draw up a lot line adjustment agreement, FindLaw explains. This type of agreement is filed with the local deeds, and must follow local zoning laws. Owners of neighboring properties generally need to agree on this type of adjustment.
