Inform tenants of the upcoming inspection
Again, allowing ample time matters here. If you manage a large building with many tenants, it may take several days before all necessary inspections are completed. Be clear about the time, date and what is involved. Do they need to be present at their premises? You will need to be very clear about the details, give all tenants enough notice and reach them through several communications channels (letters, noticeboards or email). It also helps if you can get tenants to entrust keys with you so that the inspection can go ahead even without them present.
For some tenants, having the choice to book a timeslot early in the morning suits their busy schedule. Why not check with your fire safety provider if they offer an option for tenants to self-book via an online system? This will help reduce the amount of work you need to coordinate in managing the fire safety inspection.
