Not really - the ultimate landlord could be some off-shore investment company.

Whilst they retain right of access they do not control what is placed, and where, within the property which could impact fire safety.

No good them writing keep stairs clear and then your resident places a child gate across the doorway - it needs local hands on control.

Presumably you rent the properties and then house people in them, whether on a sub-tenancy or other basis.

Which means that the landlord probably has limited control over who you choose to house in their premises.

Assuming that you house these people as part of the running of a business (commercial or otherwise - you might be housing e.g. asylum seekers) then there is a duty on you to assess whether the premises are suitable for use.

Some of those housed may need Personal Emergency Evacuation Plans, particularly where you may have put them into suboptimal accommodation, e.g. if you were to house someone who is mobility impaired and uses a wheelchair in premises where they need to use stairs in the event of fire.
