Security teams on the ground across the San Francisco metro

Data from the San Francisco Police Department shows that burglary was down 23% and total property crime decreased 20% as of October 4, 2026, compared to the same period in 2025. A system that is monitored and maintained daily addresses these risks before they escalate. Kastle's technicians and operations center cover the full San Francisco metro area, including Daly City, South San Francisco, Oakland, San Mateo, Santa Clara, and Palo Alto.

One accountable partner

Designed, installed, monitored, and maintained by one team

San Francisco's commercial real estate market is rebounding. The San Francisco Controller's Office reported in Q2 2026 that the city is entering an accelerating period of economic growth, primarily driven by the AI investment boom. Office leasing has picked up, and downtown transit indicators show stronger recovery. When a building adds tenants and employees, the number of credentials, entry points, and daily access decisions increases proportionally. Facility teams often absorb that complexity on their own. A managed access control partner takes system design, installation, monitoring, and maintenance off the internal team's workload.

Site assessment and system architecture for access control in San Francisco

Kastle's security architects evaluate each property's layout, entry points, and traffic patterns before specifying hardware. For multi-tenant buildings, the assessment covers shared lobbies, parking structures, elevator dispatch, and tenant suite separation. Kastle's team defines credential types, reader placement, and permission models during this phase. The finished design accounts for the property's risk profile and the compliance frameworks that apply. Every specification is documented before installation begins so the project scope is fixed and approved.

  • Security architects assess every entry point and risk zone.

  • Credential types and reader models specified before hardware purchase.

  • Full project scope documented and approved before installation begins.

How managed access control works

Four stages that define the managed security model

  • Consult: Kastle's security architects assess the property, map every entry point, and identify the compliance requirements that apply.
  • Design: The system is architected to the building's specific layout, credential needs, and integration requirements.
  • Install: Kastle technicians deploy readers, controllers, and software directly. No subcontractors.
  • Monitor and maintain: 24/7 monitoring, automatic updates, and ongoing maintenance are active from commissioning day forward.
