One boiler plant, five buildings — how one fail spreads

A central boiler plant, a shared fire alarm panel, one water service — on multi-building sites, a single system fail can write deficiencies across every building it serves. This thread is for shared-system strategy: what you duplicate, what you monitor, and how you document a plant repair so every affected building's items close together.

Shared systems are the leverage point of a multi-building property — in both directions. One plant room deficiency can write lines into every building it serves, but one disciplined plant routine also protects all of them at once. The documentation matters as much as the repair: when a plant fix closes items across five buildings, the proof has to travel to all five files. What's your single biggest shared-system exposure — boiler, fire panel, water service — and what have you done to keep one fail from spreading across buildings?
