I'd plan to turn the departing property into a rental (if kept) and purchase new target home as primary residence.

When renting out a lot do I have to notify some city/county department?  

It is different departments. 

I would also check with the housing department of the school and see if they have any suggestions.

I know it sounds like I'm splitting hairs but some banks write HELOCs in their residential department....which won't write Investment Properties.

The fire department investigation determine it was not electrical. 

Advertising to their H.R. department might work occasionally. 

Taking the path to least resistance when it comes to building departments and focusing on the end goal (a cash flowing unit) over it having a specific size or design that we wanted. 

What did the health department say the fix is? 

Reid at the HCD said their legal department is preparing a letter to go to cities that outlines their position on municipalities continuing to charge School District impact fees for <750sf ADU (violates new law) but don’t know when it will be done and sent out.I’d be happy to draft the letter for them as it seems like there is no sense of urgency to do it.
