Crime disorder, and fear can erode the hearts of neighborhoods and cit
ies and undo the best efforts of planners, but planners typically have
not made crime central to their concerns. This paper examines the cri
me of burglary, which may appear to be benign relative to the more vio
lent forms of crime in the United States, but in its consequences for
victims can be quite severe. Since burglars use features of the enviro
nment to increase their payoffs while reducing their risks, planners c
an help to thwart them. The burglary process unfolds in phases, and ca
n be interrupted by the offender at any point at which the information
available to the burglar at that point does not satisfy his criteria
as to the ratio of risk versus reward. The research reported on here e
xamines the phase where the burglar has already selected a house as a
target and has begun the attempt to enter it. Whether the burglary is
completed or aborted was found to be associated with neighborhood diso
rganization and home occupancy; other factors assumed to be important
at this phase of the process, such as burglar alarms, extra locks on d
oors, etc., did not prove to be so. Neighborhood disorganization and h
ome occupancy are both sensitive to programs and variables influenced
by planners, Through trying to understand and control burglary, planne
rs can develop approaches that will enable them to help deal with othe
r forms of crime as well.
