Renovations and Tenants

[Alex Dichter]

Hello,

I have a duplex with two tenants in one unit on the second floor. There is only one entry to the upstairs unit and I would like to replace their stairway and porch. I'm looking for some guidance on how to go about doing this since my contractor quoted that the job would take 1-2 weeks and during that time there would be no access to the unit because there isn't enough room to put a temporary stairway while they are building. Are there any guidelines for situations like this where the tenants would need to stay somewhere else while the renovation is in process? Thank you in advance!
