Construction work with tenant in place?

[Vu Trinh]

I'm in the process of getting my garage converted into a 400sqft attached ADU to rent out while livong in the main house. We're now thinking of moving and renting the main house out as well. Should I wait until getting the conversion done first and then move? Or should we try to look for tenants for the main house now and move. Then when we get the permit, star construction on the garage while the tenants live in the main house? Would that cause an issue with the tenants?
