@Ben WinchesterYa got a permit to carry with that name ::))

We had to get a permit through the town to perform the test.

The first step in a development is to find out what the zoning, hoa, or local laws permit to be done on the property. 

The problem is that you are using a Handyman for work they may not be legally able to do - regardless of their experience or how nice a guy they are.Doing a panel upgrade requires a permit - in every state I checked.

The contractor's name is on the permit so they could get sued or lose their license.Remember... if the project is riskier... the bids will usually be higher.

Do I need a building permit for a non-slab construction?

There was an addition to the property prior to the current owner and my guess would be that the addition was not permitted.  

Be polite, plead ignorance, go get your permits, and move on.

I'm not sure if this is of any interest to the community here, but from where I sit it's getting to be downright fascinating.With recreational cannabis legal in WA and CO - and momentum toward legalization elsewhere - we can assume there will be more and more people wanting to rent space for sanctioned, licensed growing operations.My experience and knowledge is specific to WA and is focused on the insurance aspect.

May also be prudent to upgrade the service wire but that will probably require a permit.
