| For
a neighborhood to remain healthy, its local businesses must flourish; and for businesses
to do well they must be safe places to frequent. With the increase in separating
commercial areas from residential ones, and the decline which often accompanies this
separation, it is essential that CPTED guidelines be followed when building or remodeling
commercial property. Simple design features, such as positioning cash registers near the
main entrance and keeping pay phones visible, can accomplish much in the way of making
customers feel safe and secure.
CPTED Guidelines
1. Natural Access Control
cash register should be located in front of store near main entrance
public paths should be clearly marked
signs should direct patrons to parking and entrances
there should be no easy access to the roof
rear access to shops should be provided from rear parking lots
2. Natural Surveillance
- windows should face rear parking lots for increased visibility
- window signs should cover no more than 15% of windows
- interior shelving and displays should be no higher than five feet for increased
visibility
- exterior of buildings should be well lit
- loading areas should not create hiding places
- clear visibility should be maintained from the store to the street, sidewalk, parking
areas and passing vehicles
- retention area should be visible from the building or street --- it should be a visual
amenity, not hedged or fenced off
- all entrances should be under visual surveillance or monitored electronically
3. Territorial Reinforcement
- property boundaries, where possible, should be marked with hedges, low fences or gates
- private areas should be easily distinguishable from public areas
- shops should be identified by wall signs for those parking in the rear
- awnings should be installed over rear doors and windows
- parking area should be, clearly visible from the building or street
4. Management
- operating hours should coincide with those of other neighboring businesses
- pay phones should be, call-out only and under surveillance at all times
- interior space should be well lit

Shopping malls often provide much of the public space in suburban
communities and as such can be a mixed blessing. On the one, hand they perform the
important function of town center, serving as a gathering place for the community. On the
other, a mall can serve as an attraction for criminal activity.
While the shopping mall continually grows in size and popularity, it also becomes a
haven for abnormal users and the site of a growing number of parking lot crimes. It is now
more important than ever that designers and remodelers implement CPTED principles.
CPTED Guidelines
1. Natural Access Control
- signs should clearly mark public entrances
- sidewalks and public areas should be clearly marked by way of special paving and/or
landscaping
- loading zones, with designated delivery hours, should be separate from public parking
- the parking garage should provide no exterior access to adjacent rooftops
2. Natural Surveillance
- restroom doors should be visible from main pedestrian areas and away from outside exits
- parking areas should be well lit
- loading areas should not create dead end alleys or blind spots
- all levels of the parking garage should be visible from the street or ground floor with
high intensity lighting to minimize hiding places
3. Territorial Reinforcements
- property perimeters defined by landscaping, post and pillar fencing or gates
- signs should clearly identify interior businesses
4. Management
- close-in parking should be available to nighttime employees
- business associations should work together to promote shopper and business safety

The drivethrough is potentially the perfect place for criminal activity. They are often
used at odd hours, are hidden from view, and those using them will almost certainly be
carrying cash.
The rule of thumb in the design of a drivethrough can be reduced to one word:
visibility
CPTED Guidelines
1. Natural Surveillance
- locate ATMs in front of banks facing main roads or as a drivethrough in the
drive-in teller lanes
- put ordering station for a restaurant within sight of interior
 
The 1993 bombing of Manhattan's World Trade Center sent a clear message to the planners
and designers of office buildings; as structures grow in size and pedestrian and vehicle
traffic increases, safety becomes an extremely important issue,
For Years the World Trade Center served as a model for safe and secure office building
construction regardless of the size of the structure being built. All tenants
were required to show photo identification upon entering. Metal grills with letter
sized slits covered mail slots. Garage and loading areas were secured by steel, anti-ram
barricades. No one could have foreseen the tragic events of
September 11, 2001 nor could it have been prevented by traditional security
measures.
With these types of measures, there is a fine line between a safe office building and a
fortress.
CPTED Guidelines
1. Natural Access Control
- Public entrances should be clearly defined by walkways and signage
- Building entrances should be accentuated through architectural elements, lighting,
landscaping and/or paving stones
2. Natural Surveillance
- restrooms should be observable from nearby offices
- all exterior doors should be well lit
- hallways should be well lit
- dumpsters should not create blind spots or hiding areas
- windows and exterior doors should be visible from the street or by neighbors
- all four facades should have windows

- parking areas should be visible from windows, side parking areas should be visible from
the street
- parking and entrances should be observable by as many people as possible
- parking area and walkways should be well lit
- dumpster should be clearly visible
- shrubbery should be kept under two feet in height for visibility
- the lower branches of existing trees should be kept at least ten feet off the ground
- windows should not be obstructed with signs
- windows and doors should have views into hallways
3. Territorial Reinforcement
- perimeters should be defined by landscaping or fencing
- fences should be designed to maintain visibility from street
- exterior private areas should be easily distinguishable from public areas
- security and/or reception area should be positioned to screen all entrances
4. Target Hardening
- exterior door knobs should be a minimum of 40 inches from adjacent windows
- case hardened dead bolt locks should be installed on all exterior doors with a minimum
of one-inch throw
- door hinges should be installed on the interior side of the door or tamper proof hinges
