As an out of state investor, you should always ask the turn key company what their criteria for classification is.

That could include a disgruntled guest.Look into permitting it into a "Recreation Room" instead if you want to avoid the classification as ADU. 

You'll have different market dynamics to consider, as hopefully you can acquire your additional properties in a down market to ensure that solid equity, but I wouldn't suggest you need to "graduate" to a different class if that's what you feel comfortable doing.Best luck

Guerrero I am actually trying to get away from this "classification" of different types of residential real estate...A, B, C, D, E, F, G.....means nothing to me...

First off there is a difference in classification of assistive animals.

I too find location to be more pertinent than the current classification of a property, as those variables can be changed, while the location obviously is what it is.

Building off of the previous reply from Kevin,yes it's the home was built prior to 1938 generally a CO is not required and you can get a Letter of No Objection (LNO) from the Department of buildings though it may take some time to have that produced (Can take months)Important to note that here in NYC Department of Buildings (DOB) has final say about the classification of a building and it's Occupancy.Do you need either a CO or LNO to be generated if one does not exist and there's no formal DOB classification?

I have been re-reading this a few times to really learn from it and each time I do, I realized, that post is an entire real estate class if someone is willing to really read and apply what you wrote. 

Concur these are Attorney questions.Will point out that Industrial is a zoning classification that many governmental agencies assert only industrial uses in. 

My home is in a zoning classification which currently does not allow for ADU's or duplexes or any other type of CIDU.
