Be sure and get the code from your local utility on the service entry/conduit, etc.
As I stated before, many service providers have their own code which is more stringent than NEC.
Don't do any work until you find out. You may have to pull it and re-do it otherwise. Many will not accept work not done by a reputable licensed contractor.

Find out the inspection regimen in your area. You're not an electrician. Relocating a service NEEDS TO BE INSPECTED. This for your safety, and for your insurance. Sure, you can do all your own work, no law against that. You may have difficulty getting insurance, or pay a higher rate therefore.

On Code: If it was code when it was installed, it is code today. Many of the restrictions on panel placement are relatively recent, within the last 20 years or so.
