Room Enough: METHODOLOGY: LEGAL LOTS

The identification of legal lots of record is critical to any study of land use in Monterey County. The status of a lot will determine what, if anything, can be built on it and will further determine how many units can be built. Thus, any enumeration of buildout potential must start with legal lots.

THE DIFFERENCE BETWEEN A LOT AND A PARCEL
While often used interchangeably, there is a difference between these two terms. Simply stated, a parcel is an identification for taxation purposes, while a lot is a recognized subdivision of property with a written legal description that addresses permissions or constraints upon its development.

THE DIFFERENCE BETWEEN A LOT AND A PARCEL

LOT and PARCEL are often used interchangeably. However, there is a difference. In simplest language,
a PARCEL is a quantity of land identified for taxation purposes, while a LOT is a recognized subdivision of
property with a written legal description that addresses permissions or constraints upon its development.
In the illustration below, the solid lines represent parcels while the dotted lines reference lots within a
parcel. The BLACK numbers indicate lots, while the RED numbers identify parcels. It is common for a
lot and a parcel to share the same space and have common boundaries, but this is not always the case.
For instance, it is possible for a parcel to have more than one lot, or portions of lots, as the illustration shows.
