Call the building department (or whatever) in the city (or county) that has jurisdiction.I'll guarantee you, though, if you're talking about ripping out all the plumbing in the house and replacing it, a permit is absolutely needed.

But then when you stop and think about it, you're kind of like "Wait a minute...I really am kind of losing out by storing up a savings account."

I wonder what will be in store for us all in 2015?

@Michael Rickard That's true, he would have to pay to store it at any parking garage or parking lot.  

However, there is plenty of area in the back yard for some storing units so I will definitely look into those and the furniture.

Sometimes using part of the old plumbing temporarily (like to cap off the new plumbing) saves you a trip to the store.

The city's planning department tells me I'll have to submit this form then it's up to the zoning officer if I'll be approved (they don't seem to have a clue what the zoning officer's requirements for approval are) or if I'll need to solicit neighbors within 200ft of the property to then go in front of the zoning board.

An Annual Permit: In Monroe County an owner or agent is required to obtain an annual special vacation rental permit from the Planning & Environmental Resources Department for each dwelling unit prior to renting any dwelling unit as a vacation rental unless an exemption to the vacation rental permit has been issued for the property as provided in Section 134-1(b) of the Monroe County Code.Initial Special Vacation Rental Permit Application Fee: $490.This application and fee is for initial applications only, not renewals.Renewal of Special Vacation Rental Application Fee: $100.This application and fee is for renewals only.NOTE: A special vacation rental permit is nontransferable between owners.

If that's the case, I'm not sure you want to be involved with that either.If they were running a consulting business or something not requiring people to come to the property, I'd be totally OK with that (that's like working from home), but you will have children coming, the health department for food, and a lot of other people you may not want monitoring your property.
