Land is measured by the "dunam" or 1,000 square meters. The size
of zoned land is quoted in net dunam. When purchasing unzoned land
it will usually be quoted in gross dunam. The buyer must verify
how much land will remain after expropriation for public use, such
as roads, public facilities, etc.
The
use of a property or its potential for a particular use, is determined
by the city building plan, which defines the permitted uses of a specific
site or area, and the size and bulk of a building which may be erected
on the site, as well as additional requirements such as landscaping, parking
or sewage hookups. These building plans are typically initiated by the
local government and must also receive approval at regional and national
levels. Various city as well as national and regional plans can be in
effect simultaneously, each governing a different aspect of the overall
form of an area, with one for roads, another for building rights and permitted
uses, a third for parks and public facilities, and so forth.
Land
owners can also initiate new building plans or changes in existing plans,
to enable new development on their properties or changes in use.
A potential
purchaser of real estate must check the relevant plans governing the property
he is considering in order to verify that it meets the relevant criteria,
and to evaluate the potential or danger of changes in the future. Such
changes can raise or lower the value and potential of a property. The
city plans are generally available in the local municipality or building
department, and consist of a map and set of regulations. Plans in preparation
and under consideration are normally begun at the local level, and then
publicized for public comment by the regional planning board. After all
public comments are received and dealt with, the plan is finally approved
by the Ministry of Interior. The process is lengthy, and can take several
years.
