Quick answer: for a Peninsula office property, concierge officers win where tenant experience sells the building, access-control-focused posts win where compliance and badging rule, and mobile patrol wins where the budget must cover nights and weekends. Most Class-A buildings end up with a hybrid. Here’s the honest comparison — we staff all three from our Mountain View office at 433 Sylvan Ave.
The three models, honestly compared
Concierge / lobby officers
What it is: a customer-service-trained officer at the front desk — greeting, visitor badging, package custody, after-hours access decisions. Where it wins: multi-tenant Class-A along the 101 corridor where the lobby IS the leasing pitch. Where it disappoints: buildings that really need patrols — a desk officer can’t walk floors and hold the desk at once. See concierge & lobby security.

Access-control-focused posts
What it is: officers running turnstiles, badge exceptions, visitor custody and dock control under written protocols — the biotech-adjacent standard as South San Francisco’s lab culture spreads down the Peninsula. Where it wins: lab and R&D buildings, regulated tenants, anywhere auditors ask “who was in the building?” Where it disappoints: as a hospitality experience — it’s security first by design.
Mobile vehicle patrol
What it is: marked-vehicle visits on a randomized schedule — exterior checks, door pulls, garage sweeps, lock-ups — each visit GPS- and photo-logged. Where it wins: nights, weekends, retail plazas and office parks in Daly City, San Mateo and Redwood City where a 24/7 standing post can’t be justified. Where it disappoints: sites with live overnight activity that need a human on scene continuously. See mobile patrol.
The hybrid most buildings land on
Daytime concierge at the desk, badge protocols behind it, and patrol coverage overnight — one vendor, one set of post orders, one reporting stream. That last part matters: when the desk, the dock and the night patrol all report into the same hourly photo-log system, property managers stop reconciling three vendors’ stories.
What it costs on the Peninsula
Drivers: hours (business-day vs 24/7), officer profile (concierge-trained vs standard), patrol frequency, and building count — portfolios get route pricing. Fixed hourly quotes after a free walk-through, no long-term contract. Verify any bidder’s PPO on the BSIS lookup; we’re #122829.

FAQs
Can one officer do concierge and patrol?
Not well, and we’ll say so in the assessment — splitting a post between desk and floors creates the gap incidents walk through.
Do you work with biotech badging systems?
Yes — officers train on your VMS/badging stack before day one and run NDA-bound as standard.
How fast can coverage start?
Same day to 48 hours for most Peninsula posts.
