Foundation repair on an occupied duplex?

[Christopher Oliva]

Does anyone have any advice on how to move forward with repairing the foundation on an occupied duplex? I own a duplex (I live in one side and rent the other), the foundation is starting to show signs of shifting so I'm going to get a few foundation companies to take a look at it. I'm hoping it's not too expensive of a fix since I'm catching the problem early, but I'm concerned on how to deal with the tenant if the repairs require the tenant to be out of their unit for multiple days. Do I discount the rent for the days the tenants aren't in their unit? Do I cover the cost to put them up in a hotel for the duration of the repairs? What if they decide to be difficult, would I need to wait until the unit is vacant to make foundation repairs? 

Any advice is appreciated!
