Industrial property is classified mainly into single-user and multi-user developments. A single-user site is intended for use by only one occupier, while multiple-user developments are usually subdivided into strata-titled units.

At least 60 per cent of an industrial unit has to be used for industrial activity. These include manufacturing, warehousing and production. Certain types of e-businesses such as IT infrastructure and software development are also allowed. However, they cannot be rented to pure office or shop users such as tour or maid agencies or advertising companies.

There are exceptions. For example, childcare centres and furniture showrooms are allowed within industrial developments if they support the main industrial activities if, say, parents who are working at the building need to leave their children at the centres. Non-industrial uses may occupy about 40 per cent of the industrial development.

In Singapore, all industrial properties are also categorised into two zonings
– Business 1 (B1) and Business 2 (B2).

B1 is usually intended for light and clean industrial use.

B2 zoned sites may be used for heavy industries that have a greater environmental impact.
