The Four Strategies of CPTED
Guidelines For Multi-Family Dwellings
Multiple buildings pose the same problems as single buildings, but these problems can easily be compounded by the number of dwellings and residents. Here we have a much greater number of public areas to consider: shared interior hallways, elevators, laundry rooms and parking areas.
But multiple dwelling buildings don't necessarily mean multiple problems. There's a certain amount of truth to the old saying; "There's safety in numbers" and with neighbors who take responsibility for each other there's no reason why a multiple dwelling building cannot be a safe place to live.
1. Natural Access Control
- Balcony railings should never be a solid opaque material or more, than 42 inches high
- Entrances into parking lots should be defined by landscaping, architectural design, or monitored by a guard
- Dead end spaces should be blocked by a fence or gate
- Common building entrances should have locks that automatically lock when the door closes
- Hallways should be well lit
- No move than four apartments should share the same entrance
- Elevators and stairwells should be centrally located
- Access to the building should be limited to no more than two points
2. Natural Surveillance
- Exterior doors should be visible from the street or by neighbors
- All doors that open to the outside should be well lit
- All four facades should have windows
- Parking spaces should be assigned to each unit located adjacent to that unit, and not marked by unit numbers
- Visitor parking should be designated
- Parking areas should be visible from windows and doors
- Parking areas and pedestrian walkways should be well lit
- Recreation areas should be visible from a multitude of windows and doors
- Dumpsters should not create blind spots or hiding areas
- Elevators and stairwells should be clearly visible from windows and doors
- Shrubbery should be no more than three feet high for clear visibility
- Buildings should be sited so that the windows and doors of one unit are visible from another
- Stairwells should be well lit and open to view; not behind solid walls
3. Territorial Reinforcement
- Property lines should be defined by landscaping or post and pillar fencing
- Low shrubbery and fencing should allow visibility from the street
- Building entrances should be accentuated by architectural elements, lighting and /or landscaping
- Door knobs should be 40 inches from window panes
- All buildings and residential units should be clearly identified by street address numbers that are a minimum of five inches high, and well lit at night
- Common doorways should have windows and be key controlled by residents
- Mailboxes should be located next to the appropriate residences
4. Target Hardening
- Cylinder dead bolt locks should be installed on all exterior doors
- Door hinges should be located on the interior side of the door
- Sliding glass doors should have one permanent door on the outside and on the inside moving door should have a lock device and a pin
