assume you know what you are doing so there is no risk to the house or people, and you are going to do any work "to code" even if you don't pull a permit.
You need a permit to move an electrical fixture or to put in a new fixture but not to replace a fixture. No wiring work is involved. You also need a permit to add a new window but not to replace a window in a existing opening. Renovating a bath doesn't require a permit if all electrical, drains, plumbing is in the same location. If I choose to enlarge my shower [new structural walls] I need a permit.
The scope of the job is bigger. If you aren't an electrician why would you do it yourself? We always get permits. Plus if something is wrong the county is great about helping the situation get rectified. I've been in that situation.

When I changed homeowners ins the new company came out and took pictures of every room in the house plus multiple exterior shots. We are going to be getting bids for some renovations and when that work is done I'll have them back out for new pics. They don't charge for the visit and my premium won't increase but if there is a fire I'll get the marble or granite and not corian .
