My STR is in Sandy Springs which requires a business license for <30 day (STR) rental businesses AND the owner have Home Stead Exemption (they live in the house). 

I'm a big fan of Whiting, I have some concerns about legacy pollution/soil remediation there, but great location and the prices help make up for the industrial issues.

@Sandy RL nice to meet you!

I'm looking to purchase a single family home that has a separate entrance to the basement in salt lake county, specifically Midvale, Murray, or Sandy.

Right of way setbacks, landscaping requirements, soil erosion plans, dirt permits, soil compaction, Indian survey, protected Gila monster survey or brown bats,  etc etc etc.                        

This includes assessments for issues such as lead-based paint, asbestos, mold, or soil contamination.

Quote from @Brad Sand:* I would think about remodeling the studio with the idea of easily converting it into a separate functional adu later.

Whiting is one of those areas that you need to be a bit careful though, Them and more so East Chicago have had a lot of incidents of lead and arsenic pollution in the soil.https://wgntv.com/2018/05/08/more-lead-contamination-found-in-nw-indiana-soil/

(Density, setbacks etc) Sometimes I'll set a meeting with city officials to discuss.Physical- Geo technical (soil) and Enviro- you will spend money here, but with this, architects and GC's are a waste of money.
