Does anyone have zip codes or areas to look for and or stay away from?

There were issues with termites, the electric was really not up to code, the HVAC was complete trash, there was mold, and the inspector had doubts about the health of the roof because he couldn't get into the attic to inspect it because it had been sealed off apparently for who knows what reason.

Has anyone used QR Codes on any of their marketing material?

If there are any specific chapters or time codes that felt a little off, please email [email protected] and let us know!

At best I would describe doing Airbnb in Los Angeles as a "Gray Area" since transient occupancy may be non-permitted for the zone you live in, but there is practically no enforcement of this code so there is little to fear if you keep your Airbnb activity under control. 

People can easily break bulbs when they carry stuff; code officials in one town where I iwn rentals won't pass an inspection with those old fixtures.

You really need to read the exact wording of the property code in CA.

They share any code changes per the lease agreement. 

Make sure you don’t run afoul of city codes.  

For your project, I'd really recommend going the legal route with the city, rezoning if required, and meeting the additional code requirements of a legal suite as tough as some of them are.
