Local governments often pass
zoning laws which control what buildings can be built on a lot and what they can be used for. For example, certain areas are zoned for residential buildings such as houses. Other areas can be commercially, agriculturally, or industrially zoned. Sometimes zoning laws establish other restrictions, such as a minimum lot area and/or frontage length for building a house or other building, maximum building size, or minimum
setbacks from a lot boundary for building a structure. This is in addition to
building codes which must be met. Also, minimum lot sizes and separations must be met when
wells and
septic systems are used. In urban areas,
sewers and water lines often provide service to households. There may also be restrictions based on
covenants established by private parties such as the
real estate developer. There may be
easements for
utilities to run water, sewage,
electric power, or
telephone lines through a lot. Something which is meant to improve the value or usefulness of a lot can be called an
appurtenance to the lot. Structures such as
buildings,
driveways,
pavements, patios or other surfaces,
wells,
septic systems, signs, and similar improvements which are considered permanently attached to the land in the lot are considered to be real property, usually part of the lot but often parts of a building, such as
condominiums, are owned separately. Such structures owned by the lot owner(s), as well as easements which help the lot owners or users, can be considered appurtenances to the lot. A lot without such structures can be called a vacant lot, urban prairie, spare ground, an empty lot, or an unimproved or undeveloped lot. Many developers divide a large tract of land into lots as a
subdivision. Certain areas of the land are dedicated (given to local government for permanent upkeep) as
streets and sometimes
alleys for transport and access to lots. Areas between the streets are divided up into lots to be sold to future owners. The layout of the lots is
mapped on a plat diagram, which is recorded with the government, typically the
county recorder's office. The
blocks between streets and the individual lots in each block are given an identifier, usually a number or letter. Land originally granted by the government was commonly done by documents called
land patents. Lots of land can be sold/bought by the owners or conveyed in other ways. Such
conveyances are made by documents called
deeds which should be recorded by the government, typically the county recorder's office. Deeds specify the lot by including a
description such as one determined by the "metes and bounds" or quadrant methods, or referring to a lot number and block number in a recorded plat diagram. Deeds often mention that appurtenances to the lot are included in order to convey any structures and other improvements also. In front of many lots in urban areas, there are
pavements, usually publicly owned. Beyond the pavement, there may sometimes be a strip of land called a
road verge, and then the
roadway, being the driveable part of the
road. ==Examples==
