Land Lot - Definition and Boundaries

Definition and Boundaries

A lot has defined boundaries (or borders) which are documented somewhere, but the boundaries need not be shown on the land itself. Most lots are small enough to be mapped as if they are flat, in spite of the curvature of the earth. A characteristic of the size of a lot is its area. The area is typically determined as if the land is flat and level, although the terrain of the lot may not be flat, i. e, the lot may be hilly. The contour surface area of the land is changeable and may be too complicated for determining a lot's area.

Lots can come in various sizes and shapes. To be considered a single lot, the land described as the "lot" must be contiguous. Two separate parcels are considered two lots not one. Often a lot is sized for a single house or other building. Many lots are rectangular in shape, although other shapes are possible as long as the boundaries are well-defined. Methods of determining or documenting the boundaries of lots include metes and bounds, quadrant method, and use of a plat diagram. Use of the metes and bounds method may be compared to drawing a polygon. Metes are points which are like the vertices (corners) of a polygon. Bounds are line segments between two adjacent metes. Bounds are usually straight lines, but can be curved as long as they are clearly defined.

When the boundaries of a lot are not indicated on the lot, a survey of the lot can be made to determine where the boundaries are according to the lot descriptions or plat diagrams. Formal surveys are done by qualified surveyors, who can make a diagram or map of the lot showing boundaries, dimensions, locations of any structures such as buildings, etc. Such surveys are also used to determine if there are any encroachments to the lot. Surveyors can sometimes place posts at the metes of a lot.

The part of the boundary of the lot next to a street or road is the frontage. Developers try to provide at least one side of frontage for every lot, so owners can have transportation access to their lots. As the name implies, street frontage determines which side of the lot is the front, with the opposite side being the back. Sometimes minor, usually unnamed driveways called alleys, usually publicly owned, also provide access to the back of a lot. When alleys are present, garages are often located in back of a lot with access from the alley. Also when there are alleys, garbage collection may take place from the alley. Lots at the corners of a block have two sides of frontage and are called corner lots. Corner lots may have the advantage that a garage can be built with street access from the side, but have the disadvantage that there is more parkway lawn to mow and more sidewalk to shovel snow from. In areas with large blocks, homes are sometimes built in the center of the block. In this situation, the lot will usually include a long driveway to provide transportation access. Because the shape is reminiscent of a flag (the home) on a flag pole (the driveway), these lots are called flag lots.
