What is the Shutterstock policy right now on exteriors of Private Homes? Are property releases needed like on iStock?

How about on residential interiors? Commercial interiors? Or any interior spaces?

they have got pretty strict on that lately. If you submit an image of a single home you surely need a property release.
A row of identical homes with no special architectural features can get through. But make sure you clone out house numbers and street names.

btw: Istock has become more easier to submit that kind of images. In the past they were extreme strict with that kind of stuff, but nowadays they accept a lot more ....
