Renting out rooms is fine, there are laws that permit how many people can live under 1 dwelling but if its 1 person per room it should be fine as long as room has Windows and a closet..If you're planning to do Airbnb NYC has new requirements that will take affect soon..Also keep in mind when renting out rooms in some markets Utilities are included in rent..

(My current home in Denver was my second home purchase - also a single family dwelling).

Build with an additional dwelling (detached casita/studio or in law suite)3.

Hi, Planning to build an ADU (Accessory dwelling unit) in the back, On top of my garage.

Get a SFR and roommates, or a SFR with a separate rentable portion (aka a "mother-in-law suite" or accessory dwelling unit) and you'll be subsidizing your own housing cost.I only want to buy in an area that i would live in myself, i dont have high standards but i dont want to live somewhere of poor quality or in a dangerous area either. 

A dwelling with lots of drywall holes will burn markedly faster than one without.  

(NOT a dwelling unit)?

The penalty for not doing so is at least $484 per day for each dwelling unit in violation.

Looking this up, I found that this zoning is indicative of single family dwelling.

I was about to start incurring $500 a month addiontal for a vacant dwelling policy.
