I come from the construction world, project management and fabrication mostly, and am kind of obsessed with efficiency in all my dealings, from solar LED lighting to seamless showings and leasing.  

Cutting fabric for minimum wage.

The OPs squatter could answer the complaint with some weirdness about a verbal agreement about staying longer, or counter claim harassment, or bring totally crap fabricated evidence to court.

These work really well, as long as they double them:https://www.amazon.com/Washing-Machine-Lint-Snare-Fabric/dp/B00COFAY78/ref=sr_1_13?

What they will do is find reasons to get out of the lease that are habitability reasons that are usually fabricated. 

She has tried calling the water management company saying my trees were causing her toliets to overflow, then tried calling the inspections department trying fabricate i was doing unpermitted work, and today she approached me saying she was filing a police report for harassment if i continued to try to communicate with the owner and property manager about taking the carport down (ironic, i know).

So the suspicion is that this woman works under the umbrella of her boyfriend (both self employed real estate agents) and the paperwork was likely fabricated.   

Long term pre fabricated granite or quartz for a rental you are keeping.

@Morgan GrangerThe granite fabricators also will install.

There can also be issues with thermal bridging so it would be important to choose a contractor/fabricator with experience with containers.
