Regular inspections should be part of your normal operating procedure to catch things before they get this bad.Some things to look for when a tenant's electricity turned off.... top of the list are the fire hazards: burning candles for light, using outdoor grills inside for cooking, burning wood for heat, getting electricity from neighbors via extension cords.  

Again, I realize not everybody has this perspective or hears the call of a bigger purpose, and I begrudgingly accept the title of Hippy or Tree-hugger if you see fit.

@Kyle Hipp is correct, walk throughs are not meant (for me) to nail the tenant for violations, but to save yourself money in the future by possible stopping large problems, and not spending unnecessary cash is the name of this game. 

Welcome to BP @Sammantha Ford I can't say I know anything about tiny houses, other than they are small, but given all the available space in CO and the preponderance of libertarian hippies there I would think CO would be prime for a tiny house onslaught?

You will be charge $150 for any type of flame including a candle.”

The tenants “teach” us over time by their behavior, which kind of restrictions should be added.For example... not only no smoking, but no BBQ grills on porch or deck or within 10 feet of any structure, no swimming pools or wading pools of any kind, no car maintenance on the property including oil changes, no vehicles of any kind may be on property with current license plate, if you allow pets... no vicious breeds, no trampolines, no fire pits, no use of indoor fireplaces, no candles; the list goes on and on.Bob CollettCollett Property Management

Also, it might seem counter-intuitive, but don’t be tempted to overuse febreeze/air fresheners/candles/etc. when showing the home to prospective tenants.

Then they started to keep their belongings in the space, which I didn't mind at the beginning, but recently I see they leave dangerous items such as burning candles and a standing mirror without mounting.

Be it my agency or anyone who can hold a candle to us (yes, theres a few really great ones out there, hundreds of horrible but a few great ones).
