My property management will send out a written notice that they require to enter my suite a minimum of 24 hours in advance. They will advise me of a time frame for which they will do so. It is then my responsibility to be prepared for their entry during that window or vacate the premises at that time. Not providing you a time frame, if this is the case, is unprofessional and contrary to standard rental practices.

Your property management or caretaker should also be advising you of what the problem is in the building or suite that requires such frequent attention. They should be quite frank about the work involved and an estimate of the time involved that is required to be in your suite. This is the professional thing to do. In the event they don't do you feel up to the task of asking?

I would in the future, upon receipt of the notice, contact your property manager and work out a more suitable time period. Perhaps it would be better for you to not be present. If the maintenance persons are not observing this, going to your rental ombudsman is a good action on your part.

Again, communication is key.
