Frontage is the full length of a plot of land or a building measured alongside the road on to which the plot or building fronts. This is considered especially important for certain types of commercial and retail real estate, in applying zoning bylaws and property tax. In the case of contiguous buildings individual frontages are usually measured to the middle of any party wall.

In the United States, a frontage road is one which runs parallel to a major road or highway, and is intended primarily for local access to and egress from those properties which line it.

In military parlance, a unit's frontage is the width of land which it is responsible for attacking across or defending.

River frontage and ocean frontage is the length of a plot of land that faces directly onto a river or ocean respectively. The amount of such frontage may affect the value of the plot.

For Sale By Owner (abbreviated as FSBO and pronounced /ˈfɪzboʊ/) is a real estate term which describes the situation in which a property is offered for sale directly by its owner and without that owner having solicited the help of a real estate broker, implying that no real estate commission is associated with the sale. In recent years, the term has been used more broadly to describe the process of marketing, buying, and selling of real property without the representation of a real estate broker.

Some real estate professionals in the United States use short word fizber (noun) to describe home owners who sell their homes and land by themselves and don't use a realtor. The word fizber was formed by means of agglutination from the word fizbo (pronunciation of FSBO) by adding affix -er to it.
