The only disability at issue from your end is the guy's RPD (rotten personality disorder)

A nuisance property shall be any property which is in violation of the Borough property maintenance requirements by being in a substantial state of uncleanliness, disorder or disrepair; any property substantially damaged by fire, flood or other natural disaster; any property determined to be uninhabitable by the Code Enforcement Officer; or any property which is occupied by any tenant who has engaged in any or all of the following conduct:1.

There are reasons they don't or can't, often has to do with mental issues, personality disorders that also leads to unacceptable attitudes to those who do carry the water.Saying someone is able bodied is misleading as you can't see personality disorders that can be hidden easily during short meetings with someone.

Looked at the pics.I would power wash the sidewalk next to your building as well as the entrance and patio.They are real dirty and you can see algae growing on them.You can rent concrete pressure washer with a high PSI at Lowe's or Home Depot for cheap.Make sure you spend a little higher amount to get the high psi sprayer.Do Not use it on the house but concrete only as damage can occur.The houses use a lower psi sprayer than the concrete ones.I would say you are looking at identity disorder with this property.I get your story about it but what else is around it??

If you're in for the long haul and are willing to engage the community to decrease disorder, then I would point you to best practices for community building.

There are occasionally problems with showing occupied units such as smells, disorder, etc.

oh, I also found out the HO has been arrested a few times. disorderly conduct, resisting arrest, drunk driving.

Some of them have had a lot of misdemeanors (usually disorderly conduct) when they were younger.
