Which GC insurance policies should I be additional insured?

[Don Frost]

If I hire a GC to renovate a house I want to flip, do I only need property and general liability insurance? Which general contractor insurance policies should I be named as an additional insured? If I don’t use a GC and hire all the trades myself, do I need builders risk, property and general liability insurance?

Which general contractor insurance policies should I be named as an additional insured when I hire them to work on a house I’m flipping?
