It was denied due to there not being proper working smoke detectors in the property. 

Hard wired smoke detectors, egress windows or stairs to name a few.

The second year, they all of a sudden at renewal sent a notice that I'd be required to have carbon monoxide detectors in each bedroom. 

In short, you need working windows, no cracking/chipping paint inside/outside, smoke and CO2 detectors inside, no overgrown greenery/trees outside, no holes in the walls, if you have carpet inside - it can't have stains or rips in it, and some other small stuff.

I found all sorts of things to reference for an eviction including excessive damage to the property, signs of an animal, lack of yard maintenance, oil spill on driveway, smoke detectors removed, the unit smelled of smoke, appliances that came with the unit moved off site ect... 

The fire dept just makes sure there are 2 and smoke detectors 

If anyone has any doubt about whether or not a post is AI-generated, just run it through one of the free AI detectors available online like the one Grammarly offers. 

In fact, it was even worse because they overlooked a ton of code violations (missing smoke detectors, etc.)* Accounting system is f-ed.

And when I applied for a rental license it was a really easy process, they cared more about the safety things like having enough smoke detectors and fire extinguisher and GFCI outlets near water, etc. 

lie detector determined that was a lie. btw, can you drive down to Aurora and see wth is going on down there for us?
