Advice needed...should I let them in?

[Carlotta Hall]

Im in Chicago...The house that I purchased sits next door to a house that CTA purchased to extend the Redline Train Station. They bought all of the land on this block except my house (I purchased last month for a rental) and the two houses on the corner. My problem is that they are about to demolish the house next door in the morning, and their contractors are asking me to allow them to take pictures of the inside of my home for their protection. Just incase something happens with my foundation and I try to blame them. Should I allow the pictures?. Is there anything that I should ask? They say they are building a parking lots for 8 cars on the soon to be demolished lot.
