Security teams on the ground across San Francisco

California Penal Code 487(e), effective January 1, 2025, allows investigators to aggregate multiple thefts into a single felony charge once the total value exceeds $950. The SFPD's Organized Retail Crime Task Force is actively using this tool in San Francisco, according to an SFPD press release. That enforcement environment means commercial properties face increased scrutiny around how they document and report theft-related incidents. A security provider with local presence across the Bay area, including Oakland, Berkeley, Palo Alto, and San Jose, can respond to service needs, alarm events, and system issues without delays.

Managed at every stage

Designed, installed, monitored, and maintained by one team

San Francisco's commercial real estate market is in transition. The city's office vacancy rate fell to 30.1% in Q2 2026, down 360 basis points from 33.8% one year earlier. Tenant demand reached its highest level since 2019, with AI companies driving most of the absorption. As buildings become occupied and leasing activity picks up, the security program must keep pace. A managed commercial security system covers access control, video surveillance, visitor management, and monitoring under a single provider, with every component designed, installed, and maintained by the same team.

Site assessment and system architecture for commercial security systems in San Francisco

According to the San Francisco Police Department's (SFPD) district-level data, property crime in the Southern District (which includes South of Market, Mission Bay, the Financial District, Treasure Island) rose 22.6% in 2025, recording the highest year-to-date total. Elsewhere, however, property crime fell sharply, including in Ingleside (down 42.2%) as well as the Northern (29.1%) and Central (38.7%) districts. A security system is only as effective as the assessment behind it. Kastle's commercial security installers evaluate every entry point, camera position, and access policy against your building's risk profile.

  • Walkthrough of every entry point, parking level, and shared area.

  • Risk profile matched to your building's layout and tenant mix.

  • System blueprint delivered before any hardware is specified.

Industries we protect in San Francisco

Commercial security for San Francisco’s core industries

The SFPD reported in September 2026 that it made 844 retail theft arrests during the past six months, a 27% increase over the previous six-month period. Officers recovered more than $410,000 in stolen merchandise in the past year. Larceny cases declined nearly 20% year-to-date, but these crimes "remain far too common," the SFPD noted. That enforcement activity reflects the scale of commercial theft exposure in the city, where facilities have distinct security requirements. Medical offices, high-turnover retail locations, and multi-tenant office buildings all need a different combination of access control, video surveillance, and monitoring.
