In CPTED, which principle is primarily about defining ownership and encouraging legitimate use of space through environmental design?

• A. Maintenance
• B. Natural surveillance
• C. Territorial reinforcement
• D. Natural access control

Answer: (C)

Territorial reinforcement is about signaling ownership and encouraging legitimate use through design. It uses clear boundaries and cues—the presence of fences, signage, lighting, and well-maintained landscaping—to show who owns or is responsible for a space and how it should be used. When a space looks clearly owned and well cared for, it communicates to potential offenders that legitimate users are present and actively using the area, which discourages misuse and makes illicit activity less appealing. Maintenance supports this perception, but the central idea is using physical design to define ownership and guide behavior. Natural surveillance focuses on visibility, and natural access control on guiding entry and movement, rather than signaling ownership per se.
