Specifically in regards to not having a window in the living room.Alternatively, would somebody be able to point me to good resources to look into regarding zoning rules / legal codes for specific areas?

Each option has its pros and cons, and I'm hoping to get some insights from this community to make a more informed decision.Option 1: Building an ADUPros:Increased Property Value: An ADU can significantly increase the value of my primary residence.Control and Proximity: I can closely manage and maintain the property since it's on my land.Potential for Higher Rent: ADUs in bay area can fetch a good rental price.Flexible Use: ADUs can serve multiple purposes – home office, guest house, or rental unit.No Additional Land Purchase: Utilizing existing property means no extra cost for land acquisition.Foundation improvements: I will get an upgrade for my foundation which increase house stability.

Great terms - watch out for stuff too good to be true

Just as long as your LTV after ARV is 75% or less you'd be good  

well, the good news is that your lender will be able to add back deprecation, mortgage interest, property taxes, property insurance, HOA dues and even some one time costs. 

My leading thought is to try and offload the property through one of these approaches as it is a quality home that I think I could sell to a current tenant of mine from another rental unit.

Good luck with everything! 

On a separate note, I do not believe this farm yard has any strategic value for them... it's in a very corner off of a residential road that wouldn't do any good for trucking down or anything like that.  

My pleasure and good to connect, if you need my info just send me a dm

Good luck!
