One sample, many buildings: keeping unsampled buildings honest

On a multi-building property the inspector samples buildings — and the buildings not drawn get no official look that cycle. The trap is letting the unsampled buildings coast until they are drawn next time, older and worse. The rotation that works treats the official sample as the minimum, not the plan: every building gets an internal walk on a fixed cycle regardless of sampling, and findings in a sampled building trigger a same-week check of the same system in every other building, because a boiler or panel habit rarely lives in one building alone. How do you rotate internal walks across buildings between inspections? — Admin
