Growing up in the hippie culture in southern california, I frequently saw scenes similar to these, with papers strewn around, dishes piled in the sink, random stuff piled onto dining room tables, etc.
Some comments about specific rooms (From this link, where most of the interior shots were taken):

Photo 14 - typical of an unkempt house
Photo 15 - also typical. It appears that a computer projector is set up to display on the upraised screen.
Photo 17 - piles of stuff stacked on a table are typical. I wonder about the piles of stuff on the floor, though. Again, not inconsistent with what I've seen before.
Photo 18 & 19 - piles of dishes. I've seen this many times, but another contributor did note that most of the dishes don't appear to be used. I've actually seen situations where uneaten food and even mold was present. Odd that that doesn't be the case here.
Photo 20 - cat food supplies and overall mess I've seen before. A chair on TOP of the mess, with stuff on TOP of the chair, I haven't. This suggests that someone moved the chair here because they were searching elsewhere. All the cupboards opened is a tell for LE searches.
Photo 21 - not inconsistent with an unkempt house.
Photo 24 - I've even seen things this messy, but the chair thrown on top of the mess is out of place.
Photo 25 - unkempt, but livable.
Photo 26 & 27 - mattresses thrown about and piles of stuff are out of place for a living space. This doesn't even fit the profile of a storage room - with upended matresses. The mattress appears to be new. A mess that evolves over time has to have SOME form to it, as things are piled into a room over time - a mess created in a short amount of time doesn't have any recognizable form. This screams 'police search' to me.
Photo 28 & 29 - there the bathroom is made unusable by debris and boxes on the floor. This was not done by anyone that uses this bathroom. Again, no form to the mess.
Photo 30 - mess on the floor looks 'lived in'. Piles of clothes and chair on top of the bed look like the results of a search.
Photo 31 & 32 - bags and boxes making another bathroom unusable. This also appears to be the results of a search.
Photo 34 - unkempt houses typically have some organization - Messes that evolve show purpose... papers and books stacked and organized, pathways for getting around the mess, etc. Here everything is thrown around and piled on otherwise usable furniture.
Photo 35 - another chair upended on a loveseat. Tell for a search.
