The questions a small scope still has to answer
Four things cannot be dropped regardless of size. What areas are covered, and specifically which are not. How often each is attended. When the cleaner can enter and who holds the key or code. And who is called when something is wrong. A scope that answers those four questions in half a page is more useful than a generic multi-page document that describes a building nobody has visited and leaves access arrangements to be sorted out informally later.
The exclusions question is the one small sites most often skip, and it causes the most trouble. Windows above reach height, external areas, the inside of a fridge, a stockroom the owner prefers untouched, or a tenant's private office are all common examples. Naming them takes one line each and prevents both the assumption that they were included and the awkward conversation months later about why they have never been done.
