In a house, the unit of the problem is the property. In a converted building or a shared house it is not — and treating one room or one flat while the structure around it is untouched is the commonest reason a rented property has this twice.
Bed bugs do not travel far or fast, but a converted building offers short routes that a detached house does not.
The last item is the one that matters most. Structural spread is slow and takes months. A mattress or a chair carried from one room to another moves an entire population in five minutes, and it happens at every changeover.
In a shared house, the bedrooms get looked at because that is where people sleep. The rest of it does not, and in a shared house the rest of it is heavily used.
A shared lounge sofa that several people sit still on for hours every evening is, from the insects' point of view, a second bedroom — and it is nobody's responsibility to check it.
In a house you can reasonably treat what you find and look at the adjoining rooms. In a converted or shared building the inspection is the job, because the answer to "how far has this got" changes the whole shape of the work.
That list is not a treatment list. It is an inspection list, and most of it will come back clear — which is the point, because then the treatment can be confidently narrow.
The technical part of this is straightforward. The difficult part is that a building may have several tenancies, more than one landlord or agent, and nobody with a view of the whole thing.
Houses let room by room carry two risks at once: a lot of furniture arriving from a lot of different places, and a changeover every year in which most of it moves.
Do not treat one room in a shared house on its own. The adjoining rooms and the communal seating are part of the same question, and a narrow treatment in a building is the version that is back in six weeks looking like a new problem.

Yes, through party walls, service voids, floor voids and communal areas - but slowly. Far faster is furniture carried from one room to another, which moves a whole population in five minutes.
Yes. A shared lounge sofa that several people sit still on every evening is effectively a second bedroom, and it is nobody's responsibility to check it.
Because the answer to how far it has spread changes the shape of the work. Most of the inspection list comes back clear, which is the point - it lets the treatment be confidently narrow.
