Re: Bonding and liability insurance
Usually the insurance requirements are mandated by your state licensing board or the local jurisdiction you work in.
For example, here in Florida, we are required to have a minimum of $100,000/per person and $300,000/per occurrence which includes completed operations and products. Property damage insurance is $500,000 or you can have a minimum combined single limit policy of $800,000.
Again, these are only minimum requirements for licensing and you will need to determine you total coverage needs if you plan on doing alot of work and mainly large jobs that the minimum coverage may not cover.
I carry a $1,000,000 coverage and only pay around $700 a year with a repitable agent. Insurance is generally pretty cheap.
