Measure type: Maintenance

Maintenance is the measure of discouraging crime by designing places with management and maintenance in mind.

Description

Research has shown that a lack of maintenance can act as a disinhibitor for certain crimes. A lack of maintenance over the environment can be seen as "a signal that there is little or no surveillance over an area, that there is little or no social authority exerting control over an area, and that consequently deviant behaviour may be tolerated".

Considerations

General considerations

The form of measures that are most suited to provide ownership depend on the location and use of the object. High fences and landscape that actively impede access are most appropriate in places that are vulnerable to crime, such as the back of dwellings. Lower barriers, hedges and bushes are also highly useful to signify the public/private divide.

Safety/security considerations

Wherever an increased sense of ownership leads to an increase in social cohesion, people may look out for each other. This can be expressed in security issues (by for example not accepting aggression to an fellow resident), or in safety issues (like taking care of an injured fellow resident after an accident).
